The main reason why fruit trees draw in winter is excessive water loss from shoots. Most of the draws occur on young fruit trees, especially new shoots. Due to less accumulation of nutrients in new shoots, poor water retention capacity and osmotic adjustment, low degree of lignification, and easy wind folding to form wounds, as well as the dense skin density of new shoots, the appearance of smooth moisture diffuses faster and tends to be younger. Water stress in shoot tissue. Since there is no transpiration, root water can only rely on the root pressure to provide power, slow water supply, plus intense ultraviolet radiation in the winter and high temperature burns at noon, exacerbating the death of the phantom. Second, prevention measures of fruit trees First, choose the type of anti-draw bar. The second is to effectively promote the post-control. Early application of water and fertilizer to promote deep roots and photosynthesis, in the summer by pulling branches, twisting tips, picking hearts, girdling, promoting shoot growth, autumn shoots topping, no later applied nitrogen fertilizer, more phosphorus and potassium fertilizer, spraying leaves before the application of ethephon Control growth. According to local conditions, necessary pest control. In addition, care should be taken to remove diseased shoots in winter. The trunk is painted with water and antifreeze, and it can also be wrapped with straw rope or plastic film to reduce the loss of water caused by daily burns and strong winds. Wind barriers are installed on the windward side in windy areas and lots, and are densely planted. The shape of happy-shape and Y-shape are used to make the water supply near the roots faster. Spraying carboxymethyl cellulose and other water-retaining agents before the leaves are fully developed in the early spring season can also effectively prevent excessive water loss in the early spring.
