Main points of autumn and winter maintenance of newly planted trees
Reasonable irrigation
The autumn should make the tree tissue grow more substantial, fully lignified, enhance resistance, and prepare for overwintering. Irrigation should be controlled at this time to avoid excessive growth. However, if the soil is too dry, you can irrigate it appropriately. In particular, the root system of newly planted trees is not well developed and has poor water absorption, so as to prevent the trees from wilting due to lack of water.
Increase base fertilizer
Combine basic fertilizer and then apply quick-acting chemical fertilizer to increase tree accumulation and cell sap concentration, thereby enhancing the wintering ability of trees and laying a solid foundation for growth and development in the coming year. Applying basal fertilizers in autumn will have sufficient time for organic matter to decay and decompose, and increase the degree of minerality. It can be supplied to trees in time for absorption and utilization in the coming spring to promote root growth.
Trimming and shaping
Newly planted trees should be trimmed after falling leaves in autumn, cutting off sprouting tillers, long branches, cross branches, juxtaposed branches, and diseased branches. The shrubs with the new shoots of the year are suitable for pruning in autumn and winter. The shrubs that bloom in the spring will prun the old branches and maintain the ideal tree posture after they bloom in the next spring. The pruning of trees is mainly fixed branches, and the trigeminal nine-top type is cultivated according to the characteristics of the tree. Canopy. Note that trees with poor cold resistance are pruned in early spring to avoid wind damage. The pruning sequence is "from base to tip, from inside to outside".
Pest Control
Since the beginning of autumn, the temperature has gradually dropped, and various seedlings have begun to enter the autumn secondary growth stage. At the same time, it is the peak period of pest damage. For example, the peak period of damage by the American white moth and other leaf-eating pests. Cocoons live through the winter, so it is extremely important to do a good job of preventing and controlling diseases and insect pests in autumn, reducing the number of insect populations in the coming year, and ensuring normal leaf growth of broad-leaved tree species and full winter bud formation.
Trees protect against cold and overwinter
Newly planted trees that are not cold-tolerant must be well protected from the cold. Cedar, bamboo, etc. must be surrounded by wind barriers. For tong, purple-leaf plum, crape myrtle, and hibiscus, the trunk must be wrapped with straw ropes and colored strips.
Pouring foot with frozen water
The trees have stopped growing from November to December. In order to make the trees survive the winter well and not suffer from the drought in winter and spring, the frozen water should be potted during this period, and it should be arranged around the beginning of November. The tree hole (tree hole) should be repaired according to the size of the tree. 10 times the diameter of the tree trunk), use small water to slowly irrigate. After irrigation, the water penetrates 50 cm to 100 cm of the soil (the root distribution area is 10 cm to 100 cm). It can not only meet the water needs of the tree itself, but also improve the cold resistance of the tree.
Trunk painted white
Whitening the trunk in winter can not only reduce the damage to the trunk caused by the large temperature difference between day and night in winter, but also eliminate the overwintering pests in the cracks of the bark. Whiten all the trees on the street and the trees in the green space (the whitening formula is 10 parts quicklime, 1 part salt, 40 parts water).
