The fruit trees are drawn because the watering season is too busy and excessive nitrogen fertilizer is applied to the growth of the saplings. The growth of the saplings is excessively prosperous, and the temperature in winter or early spring is high, and there is less rain and snow. The branches need water and root water supply. A serious imbalance has occurred, causing the shoots to dry out. A few are caused by the damage of Daqingye.
Preventive measures: First, spring planting is encouraged. After the autumn planting, planting can be carried out first, by digging the ditch with a depth of 50 to 70 centimeters. In the slope of the ditch at a 45 degree angle, the tree seedling is placed on the slope. The roots are filled with wet soil, and then the seedlings are placed in turn and filled with soil until the saplings are released. Then, 90% of the height of the saplings is covered with wet soil and the water is finally poured into the pits. Immediately after the convulsions in spring, the colonization was performed.
Second, after planting and drying, each tree is nested into a long plastic film bag, which can prevent rods from pulling and prevent pests. It can also promote sprouting and growth.
Thirdly, after planting, dip oil and use glycerin or animal oil to squat up from the bottom of the seedling to prevent water loss. After the colonization has occurred after the colonization, in the early April, the part of the budding part is cut off at the lower part of germination, and the remaining part is left with 2 to 3 buds in the upper part, and the rest of the buds are erased.
Fourth, when intercropping vegetables, it is necessary to pay attention to the control of Daphnia in autumn.
