Recently, Luoyang City, Henan Province, fruit farmers to ask for help from this newspaper, saying that their persimmons are not yet mature, persimmon leaves and green persimmons have fallen a lot, I do not know what caused it, I hope experts can give solutions. To this end, the reporter interviewed Tian Jiayu, a soil and fertilizer expert at the Northwest A&F University, seeking solutions. Tian Jiaxuan introduced that the fruit drop was mainly caused by pests and fruit tree pruning. Persimmon trees also need to be trimmed in time. It is necessary to balance the tree potential, combine the shrinkage, timely cut off the head, promote the branching, and cultivate the branch group to ensure the healthy growth of the persimmon tree. "In the cultivation of persimmon trees, if you do not do pest control work, there will be fruit drop. Therefore, it is not a good phenomenon to drop soft persimmons. At this time, it is necessary to do the pest control work in a timely and effective manner. When the small fruit falls, if the fruit tree has too many fruits, then the fruit drop at this time belongs to the physiological adjustment of the organism, which is a normal phenomenon. However, if the fruit falls after the small fruit falls, it is necessary to carry out pest control work." Tian Jiaxuan said. Experts suggest that for the current situation, the method of trapping can be used, which is a physical control, and there is no damage to the persimmon fruit. Mix sugar and vinegar, put the sweet and sour mixture in the bowl at night, hang it under the tree, the smell will pass, the drowning will fall, or use insecticidal lamp or sticky insect board. To the same effect. Chemical control can spray matrine, which is a highly effective and low-toxic agent. However, due to its slow effect, it can be applied 1-2 days earlier, and the drug cannot be mixed with alkaline agents. Disclaimer: Some articles on this website are transferred from the Internet.
