Before sprouting in early spring, due to too late pruning or mechanical damage, it would be difficult for the transmitting tissues of the branches to heal, and a large amount of nutritional components poured out from the wound would be wasted. Injury is light, grape production decline; in serious cases the whole plant died. Grape infestation generally occurs from mid-March to bud germination, which lasts for more than a month. In particular, the high temperatures in winter last year made it more likely to cause injury. According to the author's research on the grape injury flow in recent years, I now recommend two small tricks to prevent and treat injuries: 1. Use lime to prevent and control the wound flow, which is economical and practical, and the effect is good. The method is: add some lime to the hydration and then add appropriate water to make a thick paste. Apply it to the cut or wound. After the lime solidifies, stop the wound. 2. It is easy and convenient to use plastic to wrap wounds. The method is: Using a plastic film or two layers of plastic film, cut the mouth or the wound tightly with a string to make it airtight. Or use a plastic strip to wrap the wounded area tightly and tightly, using the impervious fluid as the degree. To remind farmers in general, do not fertilize the grapes in the early spring so as to avoid injury due to root disconnection. It is advisable to apply fertilizer in autumn, and dressing should be carried out after fruiting. Hydrolyzed Sponge White Powder Sponge Chengdu Sino Tech company , https://www.cnherbfun.cn
