Scientific comprehensive maintenance management of greening should take corresponding technical measures according to different periods of trees in order to maintain trees well. However, the project of garden tree conservation and management is very complicated, and the situation in different regions is different, and the tree species in different ages and even the same tree species are very different. But in general, there are still some rules to follow.

Key points of greening and maintenance in March:

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 rubrum, etc. ) sooty blotch has appeared, and the leaf roller moth with colorful safflower has also appeared (spraying pesticides such as cartap for control). The method of digging pupae can continue to be used to control moths.

Key points of greening maintenance in April:

1. Continue to plant trees: In early April, we should seize the time to plant trees that germinate late, uproot and replant shrubs that died in winter in time, and adequately water new trees.

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. Official: Do a good job in painting, cleaning and maintaining the green guardrail.

Key points of greening and maintenance in May:

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. ). In the middle and late May, spray turpentine mixture with the times of 10-20 and 50% triglyceride emulsion with the times of1500-2,000 to prevent diseases and kill insects. (Insecticide, Huabao and other pesticides can be used)

Key points of greening and maintenance in June:

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

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. Rose powdery mildew, kapok psyllid, etc. It should also be prevented in time.

6, do a good job of checking trees before flood control, straighten, reinforce and re-bind loose and inclined trees.

Key points of greening and maintenance in July:

Prepare the labor organization, materials, tools and equipment in advance, and submit them for inspection at any time, and handle them in time if any danger 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.

Key points of greening and maintenance in August:

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.
