1. Carry out maintenance of maintenance equipment : including lawn mowers, sprayers, water supply equipment, etc.; prepare for the purchase of various means of production, including pesticides, fertilizers, etc.

2. Planting of garden plants: Mid-to-late March is the best time to plant garden plants. The dead seedlings during the winter should be cleaned or replanted. According to the actual needs and the phenological period of different plants, some herbs, perennials, ornamental flowers and ornamental foliage plants should be newly planted and replanted. Greening renovation projects should be started early rather than late. Planting work can be carried out from the beginning of soil thawing. Generally, planting work is required to be completed before the plants sprout (before Qingming Festival at the latest). Transplanting large trees should be properly tied and supported.

3. Lawn management: Use garden machinery such as grass trimmers and hole punches to treat green spaces, which can break up the dead grass layer, increase soil permeability, and raise ground temperature early. Bald lawns should be replanted and transplanted in a timely manner, and signs should be set up to prohibit trampling. Uneven lawn plots should be filled with soil in a timely manner, and weeds should be removed at any time. The lawn should be trimmed to about 2-3 cm according to the situation and combined with grass trimming, which can promote the lawn to turn green earlier. Depending on the growth of the lawn, it should be trimmed every 15-20 days on average.

4. Fertilization and watering: According to the amount of fertilizer applied last year and the growth and fertilizer requirements of the plants, apply various fertilizers before Qingming or before flowering. Fertilization should be applied in small amounts and multiple times, and should be carried out as much as possible when it rains and when it is watered. Through reasonable fertilization, the number of flowering plants and the height of the lawn can be reduced. In years with less precipitation in winter, thaw water should be applied from the beginning of March to replenish soil moisture and nutrients and promote the growth of plant roots. Water should be applied once every 15-20 days.

5. Pest and disease control: Pay close attention to the occurrence and development of overwintering pests and diseases, and carry out prevention and control at the best time to minimize the base number of pest and disease sources and control the degree of damage caused by pests and diseases to the lowest level. For example, pay special attention to aphid control for peach trees, crabapples, Koelreuteria paniculata and pine plants; focus on plants and plots that suffered from pests and diseases last year, and spray pesticides according to actual conditions (aphids: 800 times solution of Yashima, and trunk-boring pests are controlled by "Shuchongkang" series products by root irrigation, direct trunk spraying, infusion, etc.).

6. Pruning: Prune the plants that were not treated last year before budding, remove old and dead branches and diseased and insect-infested branches, and appropriately shorten the annual branches for renewal and rejuvenation. Prune all kinds of hedges before budding.

7. Breeding: Most garden plants can be sown and seedled in early April, and preparations such as land leveling and seed treatment should be done in advance.

8. Remove cold protection: Gradually remove cold protection equipment according to the temperature. Do not put hedges and other plants in place all at once. Ventilate the area for a few days before gradually removing them.

1. Planting of flowers, plants and trees: According to actual needs and the phenological periods of different plants, continue to plant and replant some herbs, perennials, flowering plants and foliage plants; for plants that died or did not sprout during the winter, determine their survival by checking the bark and branches.

2. Fertilization and watering: According to the precipitation conditions, plant growth conditions and fertilizer requirements, apply various fertilizers (more nitrogen fertilizers) before budding or flowering. If you encounter spring drought, watering is the main method to resist drought. Water (spray) every 5-7 days to replenish soil moisture and nutrients, promote plant root growth and early greening of the lawn.

3. Pest and disease control: Pay close attention to the occurrence and development of overwintering pests and diseases, and carry out prevention and control in the best period to minimize the base number of pest and disease sources and control the degree of damage caused by pests and diseases to the lowest level. For example, pay special attention to aphid control for peach trees, crabapples, Koelreuteria paniculata and pine plants; focus on plants and plots that suffered from pests and diseases last year, and spray pesticides for prevention and control according to actual conditions (aphids: 800 times liquid of "Yashima", for stem-boring pests, inject the drug dry with a syringe and wrap it with plastic film, usually with fumigants). Manually cut off branches damaged by pests and diseases.

4. Breeding: Most herbaceous flowers can be sown and bred in mid-April. To ensure the survival rate and quality of seedlings and increase soil temperature, mulch can be used for ground covering. After seedlings emerge, spray pesticides in time to prevent and control diseases and pests and strengthen fertilizer and water management.

5. Festival flower arrangement: In late April, relevant personnel will be arranged to manage the potted flowers placed during festivals. On sunny days, water them thoroughly after 3 pm every day. Large plants can be watered according to their actual water needs. On cloudy and rainy days, water them frequently according to the situation.

1. Lawn management: Continue to rejuvenate all bald lawns, remove dead grass leaves and replant as soon as possible. Set up signs to prevent trampling. Remove weeds at any time. The temperature this month is conducive to lawn growth. On average, mow the lawn every 10 days or so according to its growth potential, and control the mowing height to 3-5 cm.

2. Management of soil, fertilizer and water: Watering this month is mainly for drought resistance. Watering should be carried out according to the situation. Generally, large trees need more water at this time, so watering should be done thoroughly. If drought continues, increase the number of irrigations. Pay attention to the water requirements of cultivated herbaceous flowers and potted flowers. Apply topdressing to all plants, mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers. Fertilizer should be applied in appropriate amounts. Apply fertilizer to lawns, dig pits around the tree trays for trees and shrubs, and dig trenches for herbaceous and perennial flowers. Water immediately after fertilization.

3. Pest and disease control: This month is a critical period for pest and disease control, and pests and diseases are concentrated. For example, if the tops of pine plants turn yellow and dry, they should be cut off immediately; peach trees, crabapples, hibiscus, large-leaf boxwood, small-leaf boxwood and other plants should focus on controlling aphids, leafhoppers, red spiders, silkworms and other pests. Try to use biological pesticides to prevent and control to avoid pollution to the environment. Generally, spray once every 7 days. Insecticides and fungicides can be used together, but pay attention to the combination of the properties of the drugs.

4. For plants that have not sprouted: Determine their survival status by checking the bark and branches. For plants that have partially died, cut off the dead branches. Protect plants with damaged bark with straw ropes. Clean up the seedlings that have completely died in a timely manner.

5. Thin out the flowers and buds of herbaceous flowering plants according to their growth conditions to prevent nutritional imbalance.

1. Lawn management: Continue to rejuvenate all bald lawns, remove dead grass leaves and replant as soon as possible, and remove weeds in time. Mow the lawn on dry and sunny days, on average every 10-15 days. The height is generally controlled at 4-6 cm.

2. Management of soil, fertilizer and water: Water according to weather conditions. In case of continuous drought, increase the number of watering. Special care should be taken for plots with poor local growth and thin soil. Supplementing peat soil with plots lacking soil can reduce evaporation and help retain water. Property management circle. Generally, the lawn is watered less before mowing, and watered after mowing in combination with fertilization. This month is the growth period of plants, so pay attention to the management of fertilizer and water. Use a mixture of nitrogen, phosphorus and potassium for topdressing and foliar spraying. If it rains continuously, phosphorus and potassium fertilizers should be used as the main fertilizers, and nitrogen fertilizers as the auxiliary fertilizers.

3. Prevention and control of pests and diseases: This month is a high-risk period for pests and diseases. Prevention is the main measure. Spray the plants in the park every 7 days. Insecticides and fungicides can be mixed, but attention should be paid to the combination of the properties. Prevention is mainly for aphids, spider mites, powdery mildew, and brown spot. For aphids, use 800 times of "Yashima", 1000 times of "Manfu", 800 times of "Fenxiu'an", and 800 times of "Yeban Tongsha" for brown spot. The drugs should be changed to avoid continuous use of the same drug to increase the resistance of pests and diseases.

4. Summer pruning: In order to keep the flowering period of roses, pearl bushes and some flowering herbs, shrubs and perennial flowers longer, they must be pruned in time after flowering. Other plants can also be pruned according to their growth potential to remove branches that are too long or too long or have diseases and insect pests.

5. Pay attention to the maintenance of sown plants, increase humidity while preventing the invasion of diseases and pests.

1. Lawn management: It has entered normal maintenance management. Weeds should be removed in time, and lawns should be planted in the bald areas. It is recommended to choose the rainy season for planting. At this time, the lawn should be in close contact with the soil below to prevent air permeability. After the lawn is planted, nitrogen fertilizer should be sprayed immediately. Topdressing should not be used. This season is hot and humid. The lawn should be perforated for ventilation. It should be trimmed in time according to weather conditions, generally keeping it about 4-5 cm. Pay attention to timely draining water from low-lying areas when watering.

2. Soil, fertilizer and water management: Pay attention to the frequency and degree of watering in this season. Try to water in the evening and drain the water in low-lying areas in time. Strengthen fertilizer management, mainly phosphorus and potassium fertilizers. Water and fertilizer loss is large in this season. Increase the frequency of foliar spraying and liquid fertilization, and appropriately add trace elements, such as iron fertilizer and zinc fertilizer. Pay attention to drainage after rain.

3. Prevention and control of pests and diseases: Peach trees, crabapples, roses and other plants of the Rosaceae family should pay attention to the prevention and control of aphids, red spiders and moths; Sophora japonica species should pay attention to the prevention and control of pests such as Sophora japonica; Conifers should pay attention to the prevention and control of longhorn beetles; Flower shrubs should pay attention to the prevention and control of aphids and spot diseases; Flowers should pay attention to the prevention and control of leaf-eating moths. Prevention is the main approach to the control of pests and diseases, and comprehensive control is used. Spray once every 7 days. Insecticides and fungicides can be mixed, but attention should be paid to the combination of the properties of the drugs. It is best to choose a windless and sunny morning for spraying, and each spray should be comprehensive and thorough. High temperature and high humidity weather is the best time for pests and diseases to occur. Send a special person to inspect the disease status of plants. Once the disease occurs, it should be cured in time. At present, underground pests are also relatively active, especially lawns and some perennial flowers. Pests that damage the roots are extremely severe. Contact killers with a 1000-fold solution can be used to irrigate the roots. In addition, pests are very active, so pay attention to the spraying location, such as dense planting, low-lying areas, and poorly ventilated areas.

4. Pruning: Mainly pruning roses, flowering shrubs, herbs and perennial flowers after flowering. Add fertilizer in time after pruning. Remove weeds in tree trays, grass, flowers and ribbons in time. Fix climbing plants with branches and wires in time. Prune dead branches, diseased branches and damaged branches in time.

1. Drainage: This month is the rainy season. After the heavy rain, drainage should be carried out in time to prevent waterlogging, especially for plants that are afraid of waterlogging, such as Pinus tabulaeformis.

2. Inspection and rescue: During periods of strong winds and heavy rains, trees are prone to falling and branches breaking. Preparations should be made in advance in terms of labor organization, materials, tools and equipment, and people should be sent to inspect at any time to deal with dangerous situations in a timely manner.

3. Pruning: Mainly for lawn and hedge pruning. Hedges should be shaped and pruned, and fungi should be sprayed after pruning to prevent fungal infection of the cut. Hedge pavilions can also be sprayed. Lawns should be pruned regularly when weather permits, once every 10 days or so, and the height of the grass should be controlled at 6 cm, slightly higher in the early stage and lower in the later stage. If the lawn grows too high due to rain and other reasons, it should be pruned in two times. The first time, the highest gear only cuts off the top, and the second time, it is cut to an appropriate height at a lower gear.

4. Replanting and reseeding of lawns: Due to diseases and insect pests, the lawn may suffer from alopecia. If it cannot recover in time, replanting or reseeding is necessary. If sowing is required, it can be done in the second half of the month.

5. Soil, fertilizer and water management: This month, waterlogging prevention is the main focus. After the rain, water accumulation in tree trays and low-lying areas should be removed in a timely manner. However, if drought continues, watering can be increased. Topdressing should be applied to seedlings with weaker growth potential, using a mixture of nitrogen, phosphorus and potassium fertilizers.

6. Pest and disease control: Pay attention to the damage of pests such as aphids, scale insects, red spiders, noctuids, and locust tooth gourds; in addition, prevent the invasion of diseases such as powdery mildew, brown spot, rot, downy mildew, and black spot; pay more attention to the damage of underground pests for lawns and perennial flowers. Generally, spray the pesticide once every 7 days. If pests and diseases have occurred, spray the pesticide once every 2-3 days, and spray the pesticide three times in a row, but the concentration of the liquid should not be too high.

1. Maintenance of hedges, roses, and perennial flowers: Pay attention to the dry and wet conditions when watering. Water thoroughly each time, but avoid water accumulation, because there is a temperature difference between day and night in mid-to-late September. If the humidity is too high, it is easy to get black spot disease. Pay attention to pruning. The autumn tips of hedges may grow unevenly, so prune them according to requirements; roses and flowers may be used in conjunction with the National Day, so control the flowering period according to the growth conditions, and spray phosphorus and potassium fertilizers to shape the flowers.

2. Maintenance of evergreen trees: Apply phosphorus and potassium fertilizers before watering to strengthen the roots and branches. Spray nitrogen fertilizer on the leaves to enhance the color and texture. Burning may occur in places where evergreen trees are planted too densely. Pruning can be done according to the ornamental effect, or transplanting can be done in late September according to weather conditions. When planting near roses, pay attention to rust. If it occurs, spray "Fenxiu'an" 800 times diluted in time. If it is serious, prune the diseased branches and burn them in time. In addition, pay attention to the prevention and control of scale insects and pine nematodes. For scale insects, spray "Piaolu Jiezhi" 800 times diluted in time.

3. Maintenance of deciduous trees: Mainly moth control, prevention first, comprehensive control. Combine watering with topdressing, mainly phosphorus and potassium fertilizers, the purpose is to increase root growth and cold resistance. Pay attention to pruning diseased branches, weak branches, and broken branches. Watering should not be too frequent at this time.

4. Maintenance of flowering shrubs: The key is to prevent and control aphids, scale insects, red spiders, powdery mildew, and black spot disease; water thoroughly, but not too much; fertilize in conjunction with watering, mainly with phosphorus and potassium fertilizers, and you can also use "Leaf Power" to spray the leaves to increase leaf color texture and shape the flowers.

5. Lawn maintenance: This month is the best growth period for lawns. Lawn transplantation is effective quickly, and renewal and rejuvenation should continue. Select healthy lawns to replant dead plots. Mow once every 10 days depending on the growth situation. Appropriately lower the mowing height each time, increase the mowing frequency, and appropriately increase fertilizer and water to extend the greening period of the lawn. At this time, prevent the damage of lawn rust and underground pests, and prevent and control according to the situation. Rust is generally treated with a mixture of 1000 times diluted "Fenxiu'an" and fungicides such as "Genjian". Underground pests can be irrigated with 800 times diluted "Disong No. 1", or "Dongfangzan" can be spread. After pruning, spray "Ye Li" on the leaves to prevent diseases and insect pests.

6. Arrangement of flower beds: Preparations for flower beds should be made in early September, and they should be placed in mid-September. After the flower beds are placed, they need to be managed by a dedicated person. Water them once a day on sunny days. If they are planted directly on the ground, water them according to the soil moisture. You can spray "Ye Li" foliar fertilizer.

1. Fertilizer and water management: The temperature difference between day and night is large in this season, so pay attention to the amount and time of watering. Generally, flowering shrubs, lawns and flowers still require a lot of water. Choose to water them before 10 am, so that a day can be used for evaporation to avoid black spot disease caused by excessive humidity at night; apply the last fertilizer to green seedlings in mid-to-late October, and you can bury "floating green ball fertilizer".

2. Prevention and control of diseases and pests: The focus is on green spaces and flowers, which are mainly attacked by red spider mites, leaf-eating moths, scale insects, rust, and black spot. However, if fungal diseases occur, immediately remove the diseased branches and burn them, and then spray "Yeban Tongsha" and "Fenxiu'an" for prevention and control. In addition, the overwintering pests have begun to choose nests, so the amount of medicine and the number of spraying can be increased to completely clear them out.

3. Pruning: Lawns, hedges, flowers and other plants can be pruned comprehensively. The last pruning should be done at the end of October. Generally, 5-6 cm is left on the lawn, and the hedges are also appropriately reduced in autumn. Flowers should be pruned according to their growth to remove weak and diseased branches. Perennial flowers will gradually die by the end of the month and their branches and leaves can be ignored. Roses can be pruned back for renewal and rejuvenation.

4. Management of National Day flower beds: In early and mid-October, they should be maintained according to normal management, but the flowers will gradually wither and should be pruned in time to improve the ornamental effect. However, by late October there will be almost no ornamental effect, so they should be cleaned up in time.

1. Pruning: Pruning is done in combination with cold protection. Prune weak branches on large trees, and prune shaped trees according to their shapes. This is also called winter pruning.

2. Watering with frozen water: Water all plants thoroughly before the end of this month, especially large trees and lawns. Ensure that they are adequately watered. When the temperature is too low, try to arrange watering at noon. When watering, you can dilute the fungus and medicine and irrigate together.

3. Cold prevention: Whitewash trees; shade cedars; contract for newly planted trees; build sheds and cover hedges planted this year. Cold prevention work must be thorough.

4. Pest and disease control: Pests should no longer be active at present, but you can apply rat poison to hedges and flowers to prevent groundhogs from infesting the area, but you must put up warning signs.

5. Others:

1. Plants that cannot overwinter outdoors need to be moved into a greenhouse for maintenance as soon as possible.

2. Check the irrigation system and drain all the water from the pipes with the drain valve after the last watering to prevent freezing and cracking. Cover all manhole covers with plastic film and then straw mats to compact them.

3. Snow and wind prevention: Clear the snow accumulated on the trees in time after snow to avoid breaking the branches; trim the branches broken by the wind in time after strong winds, and reorganize the trees to prevent cold after snow and wind.

4. Fire prevention: As we enter the dry winter season, special personnel will conduct patrols to avoid fires.

5. Garbage management: Assign special personnel to clean up garbage in the park.
