This year, there is a lot of rain, and the climate is good for winter wheat sowing, but for fertilizers that are too large and overly pruned, orchards are harmful. It is of utmost importance to distinguish between advantages and disadvantages, and to determine the law according to the situation and change the damage. After the fruit trees entered the mid-to-late September, the vegetative growth basically stopped, and the roots entered the third peak of growth. The tree nutrients began to accumulate highly, and the late-maturing cultivars began to be sugar-stained. At this time, if there is excessive water shortage in the underground, it is not conducive to nutrient conversion and fruit coloring, and the fruit has bad taste. Moderate rainfall can not only solve the adverse consequences caused by water shortage, but also provide favorable conditions for restoring tree vigor, increasing nutrient accumulation, and improving fruit quality and flower bud quality; however, excessive rainfall can easily stimulate the growth of fruit trees. , A large number of strips, waste of nutrition, weaker tree vigor, the tree is very vulnerable to disease infection. Therefore, due to the regulation of the situation, in addition to the foliar spray of nutrients and fungicides, the management of trees needs to be converted, and the use of bio-organic compound fertilizers under the trees, but also to strengthen orchard drainage to prevent the root system, the grass orchard to Grass regulates balance. The second peak of rot disease occurred in the middle or late September. To carefully inspect the trees and old orchards with more wounds and find the disease, we should take preventive measures in time.
