A lot of fruit farmers have asked us if they need to strengthen orchard management after fruit harvesting. Experts clearly stated that it is very necessary to strengthen post-harvest management of orchards and give the following suggestions to the majority of growers:
Disease prevention and insect protection
The correct management of the harvesting results is directly related to the growth and results of fruit trees in the second year. The first work that farmers should do after harvesting is the disease prevention, insecticide and leaf protection of the orchards. Because there are still some insects in the park that damage the leaves, some of them cause defoliation, so they have to fight some fungicide and kill. Insecticides prevent insects and insects. This applies to all fruit trees. Do not allow leaves to fall off in advance because the photosynthetic nutrients produced by the leaves from the time they are harvested to the time before the leaves are used for the late and next year of the tree. During growth, the nutrients stored by the tree determine the cold resistance of the fruit trees in winter and the disease resistance of fruit trees in the second year. The more nutrition is stored, the cold resistance of the fruit trees and the second year of disease resistance. The better. The growth of fruit trees in the second year also depends on the nutrition that was stored in the previous year, and more than 40% of the nutrition of the fruit trees before the early summer shoots were collected from the time when the leaves were harvested.
Improve leaf photosynthetic efficiency
Improving the photosynthetic efficiency of the leaves by applying foliar fertilizer is another important aspect of post-harvest management of fruit trees. In the process of spraying foliar fertilizer, a large number of elements and trace elements need to be supplemented. The symptoms of zinc deficiency and iron deficiency in the second year of fruit trees are due to too little nutrition accumulated in the previous year, and the fruit trees in the second year are In the process of sprouting, there will be some illnesses after very few nutrient accumulations have been consumed. Therefore, special attention should be paid to the nutritional supplement of fruit trees after defoliation, especially the supplement of trace elements. If it does not make up, the second year's deficiency factors. It will be shown soon. In the process of spraying leaf surface fertilizer, attention should be paid to both positive and negative surfaces, and the fruit trees need less trace elements, so the method of adopting foliar spraying is very effective.
Grasp fertilization
After the fruit is harvested, we must pay close attention to fertilization. Whether it is organic fertilizer or chemical fertilizer, we must step up and strive to complete in September. At this time, the root system grows and absorbs vigorously. Remind the majority of farmers not to wait until the leaves have fallen before fertilizing. This time fertilization is no longer useful, because the roots have stopped growing, stop absorbing nutrients, and the applied fertilizer can not be absorbed, even if it can absorb part of it, it can only wait until the second year.
