Support the trunk. After transplanting, the tree must be fixed to prevent the crown from skewing, and fixing the root system is beneficial to the root growth. Generally, the three-column support method is adopted to support the tree firmly and ensure the stability of the tree. Usually after one year, the big tree roots can be removed after they are restored.

Water and fertilizer management. Generally, from June to September, most of the time the temperature is above 28℃ and the humidity is low, which is the most difficult period to control. If improper management leads to water shortage in roots and cracking in bark, trees will die. At this time, the management should pay special attention to: first, sun protection; The second is root irrigation; The third is to keep the trunk leaves moist. In spring, there is much rain and high temperature. At this time, the main thing is to resist flooding. Measures to keep out the cold and keep warm should be strengthened in winter. First, wrap it with straw rope to keep warm.

Fertilize after planting. The transplanted trees are seriously damaged and cannot be fertilized in the first year after planting. According to the growth of trees, farmyard manure or foliar fertilizer should be applied 2-3 times in early spring and autumn of the following year to improve the nutritional level of trees and promote their health. At the same time, prevent excessive fertilization from damaging the root system and use it carefully.

Prevention and control of pests and diseases. When the tree saw is transplanted, there are many wounds, tender buds and leaves, and the trees are weak in resistance and vulnerable to pests and diseases. If you don't pay attention to prevention, pests or trees may die soon after infection, so you should strengthen prevention. The newly grown branches and leaves are easy to cause aphid damage, so it can be controlled by mixing carbendazim, thiophanate, triamcinolone acetonide and spraying 1200 times diluted liquid medicine. It is divided into three stages: April, July and September. This medicine is sprayed continuously every seven days in each stage, which can achieve the purpose of prevention and control in general.
