What are the lease and maintenance schemes for flower green plants?

Winter pruning: comprehensively pruning deciduous trees; Prune dead branches, disabled branches, pest branches and branches that hinder overhead lines and buildings. Inspection of street trees: check the binding and stacking of street trees in time, and rectify immediately if loose, lead wire embedded and pile body shaking are found. 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. Green space conservation: attention should be paid to the removal of large weeds in green spaces and flower beds; 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.

Maintenance is basically the same as that in June 5438+ 10. 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. Pest control: continue to prevent 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. Planting trees: Spring is a good 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. 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. Fertilization: after the soil is thawed, apply base fertilizer to the plants and irrigate them. 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. 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. Irrigation: Continue to water the green land in time.
