What is the greening maintenance plan from 1 to 12?

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, disabled branches, pest branches and branches that hinder overhead lines and buildings.

2. Inspection of street trees: check the binding and piling of street trees in time, and rectify immediately if it is found to be loose, buried with lead wire and shaking piles.

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.

4, green space maintenance: green space, flower beds and other places should pay attention to pick out big 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 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 appeared in sooty blotch, as did Euonymus japonicus (controlled by spraying pesticides such as cartap). 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 move to bark crevices, tree holes, trunk bases, corners and other places to secrete white waxy thin cocoons and 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.

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.

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 500? 800 sprays. (or spraying compound BT emulsion) continue to artificially capture longicorn beetles.

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.

First-class maintenance quality standard

1, sufficient greening, reasonable plant configuration, loess is not open.

2, garden plants to do:

(1) Growth potential: good. The growth amount exceeds the average growth amount of this tree species (the average growth amount is to be determined after investigation).

(2) Strong leaves:

① The color of the leaves is normal, and the leaves are large and thick. Under normal circumstances, the leaves are not yellow, scorched, rolled or defoliated, and there are no insects, urine, insects and net dust on the leaves;

② The heaviest leaf bite is below 5% per plant (including 5%, the same below).

(3) Strong branches:

① There are no obvious dead branches, dead branches and thick branches, and the new branches are lignified before winter;

(2) live eggs and worms without stem borers;

(3) The most serious main branch of scale insects has live insects 1 each below 100 square centimeter (including 1 each, the same below), and the smaller branch has less than 5 live insects per foot (including 5, the same below); The number of plants is below 2% (including 2%, the same below);

(4) The crown is complete: the branch points are appropriate, the distribution of main and lateral branches is balanced and the number is appropriate, the inner room is not chaotic and ventilated.

(4) Good measures: seriously carry out maintenance according to the requirements of first-class technical measures.

(5) There are few trees on the street.

(6) The lawn coverage rate should basically reach100%; Lawn weeds should be controlled within 10%; Lush growth, normal color, no yellowing; Prune more than 6 times a year in warm land type and more than 15 times a year in cold land type; No pests and diseases.

3. There are no dead trees in street trees and green spaces, and the trees are trimmed reasonably and beautifully, which can solve the contradiction between trees and wires, buildings and transportation in time.

4. Greening produces garbage (such as branches, leaves, grass foam, etc. ) key areas can be cleared with the production, and other areas and road sections can be cleared daily; Green space should be clean, free of bricks, bricks, baskets, plastic bags and other wastes, and kept clean regularly.
