The first is to do a good job in the replanting of green seedlings, conduct a comprehensive statistical survey of dead seedlings in the green belt in winter, and seize the current favorable opportunities for replanting, replacement, and timely watering to ensure the survival rate of new seedlings. The second is to do a good job of renewing improved seedlings. Seedlings of improved seedlings are a prerequisite for improving the green landscape. With the rapid development of society, some of the original trees cannot grow to meet the needs of green space and must be replaced in time. 2. Add water. Watering in spring is very important. The author thinks that watering two to three times better water in spring by practicing autumn plant seedlings. 3. Fertilization Management of soil fertility and water is an important part of seedling management. After thawing, the soil should be applied with quick-acting he-p-k and organic fertilizer. Spring is a period of vigorous plant growth. 4. Demolition of cold protection facilities should be treated differently. For relatively strong seedlings, the measures of burying soil at the roots are adopted, which can be dug out by soldiers when pouring frozen water in early spring. The tree-wrapped rope seedlings can be removed during germination (if the distance between the leather ropes is large and cannot be removed, continue to keep); the covered flowers and shrubs should take a step-by-step method to remove the landscaping non-woven film for beautification, which can be used in early spring On the south side of the hole, and then increase the number of holes every week, in early April will be all the non-woven film removed. When the monsoon wind stops, the wind deflector can be removed at the end of the spring and the support can be maintained. 5. Pruning and pruning should be based on different species, different types of seedlings, pruning, different locations, different ecological characteristics, weak branches, and branches with diseases and insect pests. The dead branches should be cut off, and the excessive growth of the branches should be properly contracted to improve the air permeability inside the canopy Under the conditions of light transmission, ideal trees are cultivated to ensure that trees and grain molds grow smoothly and cut exquisite shapes. 6. Prevent dull buds Stagnant buds means that the seedlings do not germinate when they germinate, which are mainly caused by deep planting in autumn, low ground temperature and slow root growth. When there are no buds, the plant can be uprooted and replanted. The planting depth should be 5 cm above the top root. The soil must be firm after planting to prevent it from leaking, depending on the level of soil moisture after watering. 7. Pest control Establish a pest prediction and forecast system, and arrange for special personnel to be responsible for observation and monitoring. Combining the occurrence rules and growth habits of various pests and diseases, scientifically formulate prevention and control plans to realize early detection and treatment, and ensure the healthy growth of green seedlings.
