Cause The main reason for fruit tree draws in winter is excessive dehydration of branches. Most draws occur on young fruit trees, especially on new shoots. The new shoots have less nutrient accumulation, poor water retention and osmotic adjustment ability, lower lignification, and are prone to wind and wound formation. In addition, the new shoots have a large skin pore density, and the appearance of smooth water spreads faster, which can easily cause young Water stress in shoots. Because there is no transpiration pull, the root water can only be powered by root pressure, the water supply is slow, coupled with the strong ultraviolet rays in winter and high-temperature burns at noon, which exacerbates the death of young shoots. Measures First, choose varieties that are resistant to drawing. Followed by effective forward and backward control. Deep application of water and fertilizer in the early stage promotes deep root rooting and photosynthesis. In the summer, pull branches, twisted tips, topping, ring peeling, and shoot growth are promoted. In the autumn, new shoots are towed. Control growth. The trunk is coated with water-retaining antifreeze, or it can be wrapped with straw rope or plastic film to reduce the loss of water caused by sunburn and strong wind. In windy areas and sections, wind barriers are set up on the windward side, which are reasonably densely planted and adopt happy and Y-shapes to make branches closer to the roots to supply water more quickly.
