Yellow leaves of fruit trees Excessive rainfall can easily cause the supply of major nutrients to be full or even excessive. It also causes the supply of some elements to fall short. This leads to the phenomenon of yellow leaves in fruit trees. Therefore, after the rain, we should do a good job of top-dressing in a timely manner, combine underground fertilizer and foliar fertilizer, and supplement the nutrients missing from fruit trees. Before application, observe the symptoms of deficiency and supplement the corresponding elements. At the same time, it is necessary to control the growing fruit trees. Appropriate fertilization, increased fertilization, help restore tree vigor. With 0.3% potassium dihydrogen phosphate solution, every 10 days or so foliar spray, even spray 2 to 3 times, spraying foliar spray can be carried out simultaneously with the drug. Affected heavier orchards should take more points to apply topdressing phosphorus and potash fertilizers, special fertilizers for fruit trees, diammonium phosphate, etc., about 40 kg per mu. Causes rot The main reason for rotten roots is caused by the low orchard or poor drainage work after heavy rain. Due to too much water, the root system appeared anoxic phenomenon, thereby rooting and affecting the supply of nutrients, resulting in rapid wilting of the leaves, followed by rot. In this case, eliminate water. After the storm, individual orchards are low-lying and the accumulation of water after the rain will cause anaerobic respiration of the roots of the fruit trees. This will cause some roots to root and affect nutrient supply, resulting in rapid wilting of the leaves in the short term and crushed roots. It can be drained in open drains, and after turning it over slightly, it can be used to produce lime and spray to savor sterilizing. Flower bud differentiation blocked The prolonged growth of fruit trees caused by heavy rain will affect the conversion of vegetative growth to reproductive growth of fruit trees, so that the nutrient distribution of fruit trees will be less effective in flower bud differentiation, resulting in impeded differentiation of flower buds, poor differentiation, and then affecting the yield in the coming year. Therefore, it is particularly important to work in the summer. It is necessary to remove too many back branches in time, or to use branches to adjust the tree potential, so as to balance and coordinate the supply of nutrition. Spraying potassium dihydrogen phosphate and growth inhibitors can also be used to promote the benign process of flower bud differentiation. Clear Garden Pruning The turmoil will cause the orchard to be messy and decay. The garden should be cleared in time to strengthen post-disaster pruning. Fruit orchards in the orchard must be completely removed from the orchard that has been produced, and digging deep outside the orchard. Cut off the broken sticks, clean out the park and focus on burning, so as to reduce the spread of germs and promote air and light transmission. If the fruit bag is damaged and the fruit is not damaged, the damaged bag is removed, the fungicide is sprayed again, and the solution is allowed to dry and the bagged soil is straightened again. For fruit trees that lean or fall on the ground after the disaster, support the soil in a timely manner. Whether orchard management is in place directly affects the growth of the tree, fruit production and quality. Therefore, the orchard management after the rain can not be ignored, and the management work must be in place. Disclaimer: Some articles in this website have been transferred from the Internet.
