Scientific comprehensive maintenance management of greening should take corresponding technical measures according to different periods of trees in order to maintain properly and well. However, the project of garden tree conservation and management is very complicated, and the situation in different regions is different; There are great differences among tree species, even within the same tree species and between different ages. But in general, there are still some rules to follow. Now, taking the projects in recent years as an example, the main maintenance and management projects in a year are made into annual work calendars on a monthly basis:

1 month: the month with the lowest temperature throughout the year, and the open trees are dormant.

1. Winter pruning: comprehensively prune deciduous trees; Prune dead branches, residual branches, insect and disease branches and branches that hinder overhead lines and buildings on Platanus acerifolia and large and small trees.

2. Check the street trees; Check whether the streets are covered with sand (⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ ⑾ 3. Pest control: Winter is a favorable season to eliminate garden pests. The pupae and cocoons of moths can be dug up in the loose soil under the tree and burned to death. In mid-June, 5438+10, the scale insects began to move, but at this time, they moved slowly, so we can take the method of scraping off the larvae on the trunk. Controlling pests in winter often gets twice the result with half the effort.

4, green space maintenance: street green space, flower beds and other places should pay attention to pick out large weeds; The lawn should be picked and trimmed in time; Pay attention to the antifreeze and watering of green space.

February: The temperature is higher than last month, and the trees are still dormant.

1, maintenance is basically the same as 1.

2. Pruning: continue to prune dead branches and diseased branches of Platanus acerifolia and large and small trees. Prune all kinds of trees before the end of the month.

3. Pest control: continue to control moths and scale insects.

March: The temperature keeps rising. After the middle period, trees began to sprout, and some trees (such as camellia) bloomed in the later period.

1, planting trees: Spring is a favorable time to plant trees. After the soil thaws, we should seize the opportunity to plant trees immediately. Before planting trees of different sizes, do a good job in planning and design, dig (plane) tree pits in advance, transport them with digging, and water them with planting. When planting shrubs, we should dig, transport and plant them, and water them properly to improve the survival rate of seedlings.

2. Spring irrigation: due to the drought and windy in spring, the evaporation is large. In order to prevent the spring drought, the green land should be watered in time.

3. Fertilization: After the soil is thawed, apply base fertilizer to the plants and irrigate them.

4. Prevention and control of pests and diseases: This month is a critical moment to prevent and control pests and diseases. Some seedlings (such as pittosporum, etc. ) appears in sooty blotch, and so does Euonymus japonicus (using cartap and other pesticides to control it). The method of digging pupae can continue to be used to control moths.

April: The temperature continues to rise, and trees sprout, bloom or spread their leaves into a vigorous growth period.

1. Continue to plant trees: In early April, we should plant trees that germinate late, pull out and replant shrubs that died in winter (azaleas, safflower, etc.). ) in time, and fully water the new tree.

2. Irrigation: Continue to water the green land in time.

3. Fertilization: combined with lawn and shrub irrigation, topdressing with quick-acting nitrogen fertilizer, or foliar spraying as required.

4. Pruning: You can prune the evergreen hedge by cutting off dead branches in winter and spring.

5. Pest control: (1) After molting for the second time, the scale insects gradually move to bark cracks, tree holes, trunk bases, corners and other places to secrete white waxy thin cocoons to pupate. You can use a hard bamboo broom to sweep, and then concentrate on burying or soaking. Or by spraying pesticides such as cartap. (2) Apriona longicorn begins to move, and larvae can be removed by grafting knife or homemade steel wire, but the smaller the wound, the better. (3) Prevention and control of other pests and diseases.

6. Green space maintenance: pay attention to weeds and climbing plants in large green spaces. Lawns should also be picked and trimmed.

7. Grass flowers: Replace winter grass flowers in May Day, and pay attention to watering.

8. Others: paint, clean and maintain the green guardrail.

May: The temperature rises sharply and trees grow rapidly.

1. Watering: During the tree exhibition in Ye Sheng, the water demand is very large, so water should be done in time.

2. Trim: Trim the residual flowers. Trees on the roadside were pruned for the first time.

3. Pest control: continue to focus on catching longicorn beetles. The first generation of stickleback moth has hatched, but it has not reached the degree of harm, so the reserve should take corresponding measures according to the actual situation. Sooty blotch caused by scale insects and aphids. It has also entered the peak period (for crape myrtle, pittosporum, oleander, etc. ). Spraying turpentine mixture with 10-20 times and 50% triglyceride emulsion with 1500-2000 times in the middle and late May to prevent diseases and kill insects. (Insecticide, Huabao and other pesticides can be used)

June: The temperature is high.

1, watering: plants need a lot of water, so they should be watered in time, instead of "eating with the weather".

2. Fertilization: combine loosening soil, weeding, fertilizing and watering to achieve the best effect.

3. Pruning: continue to peel buds and remove tillers from street trees. Trim hedges, balls and some flowering shrubs.

4. Drainage: Pay attention to drainage in low-lying areas during rainstorm.

5. Pest control: In the middle and late June, the moth enters the peak of incubation period, and measures should be taken in time. At present, 50% acetaminophen emulsion is basically sprayed 500-800 times. (or spraying compound BT emulsion) continue to artificially capture longicorn beetles. Powdery mildew of rose and tree lice of tung flowers should also be prevented and controlled in time.

6. Check the trees before flood control, straighten, reinforce and re-bind the loose and inclined trees.

July: The temperature is the highest, and there is strong wind and heavy rain after the middle.

1, Transplanting Evergreen Trees: In rainy season, conifers and bamboos can be transplanted, but pay attention to the weather changes, and water them in time in case of high temperature.

2. Drainage: Drainage should be done in time after heavy rain.

3. Topdressing: Dry apply quick-acting fertilizers such as nitrogen fertilizer before it rains.

4. Roadside trees: Trim the branches that contradict the wires and check the stumps one by one. If they are loose or unstable, they should be righted and fastened immediately. Prepare the labor organization, materials, tools and equipment in advance, and send someone to check at any time, and handle the danger in time when it is found.

5. Pest control: continue to control longicorn beetles and borers. We can use 50% cartap 1: 50 times solution to control longicorn beetles, and then seal the hole, which can also achieve good results. The moth of camphor tree should be cut off in time, and the insect nest should be destroyed to avoid further harm.

August: It's still rainy season.

1. Drainage: After heavy rain, low-lying accumulated water should be drained in time.

2. Typhoon prevention work for street trees: Continue to do typhoon prevention work for street trees.

3. Pruning: In summer, in addition to general tree pruning, hedges should be trimmed.

4, intertillage weeding: weeds grow vigorously, weeding in time, can be combined with weeding for fertilization.

5, pest control: mainly catch longicorn beetles, pay attention to the roots of longicorn beetles. Aphids and camphor moths should be controlled in time. Pay attention to powdery mildew and rot in wet weather and take timely measures.

September: The temperature drops, so do a good job in welcoming the National Day.

1, pruning: In order to meet the needs of city appearance, street trees are stripped below the tertiary fork. Hedge modeling pruning. Weed and mow the lawn in the green space, clean up dead trees in time, and make the green space clean and tidy.

2. Fertilization: For some trees with weak growth and insufficient branches, some phosphorus and potassium fertilizers should be applied as topdressing.

3, grass flowers: welcome the National Day, change grass flowers, choose colorful grass flowers, pay attention to adequate watering.

4. Pest control: perforation (cherry blossom, peach, plum, etc. ) for the peak, with 500% carbendazim 1000 times solution to prevent infection. Long-horned beetles began to turn to the roots for harm, so attention should be paid to catching the root beetles. Moths on willows should also be prevented in time. Do a good job in the prevention and control of other pests and diseases.

5. Check all kinds of greening facilities before the festival.

October: The temperature drops. 10 In late October, early winter began, trees began to shed leaves and gradually entered a dormant period.

1. Prepare for planting trees in autumn. As soon as the cold-resistant trees shed their leaves in the later stage, they can be planted.

2. Green space maintenance: clear dead trees in time and water them in time. It is necessary to do a good job of picking grass and trimming the green space and lawn. Grass flowers that don't grow well should be fertilized

3. Pest control: continue to catch longicorn beetles. Camphor moths should also pay attention to observation and prevention.

1 1 month: At night, the soil begins to freeze and enter the deep winter festival.

1. Tree planting: Continue to plant cold-tolerant plants, and finish before the soil freezes.

2. Turn over the soil: Turn over the soil in the green space to expose the pests that are about to overwinter.

3. Water: Water the dry and hard soil before freezing.

4. Pest control All kinds of pests are preparing for winter in the later stage, and the control task is relatively light.

1February: The temperature is low, and the winter maintenance work is started.

1. Winter pruning: Prune some evergreen trees and shrubs.

2. Eliminate overwintering pests and diseases.

3. Prepare for next year's adjustment: After deciduous plants shed their leaves, observe the nature reserve and draw the orientation to be adjusted.
