After heavy rain, many fruit trees are seriously damaged, and long-term accumulation of water in the later period will lead to yellow leaves and weak tree vigor. In severe cases, dead trees will be caused, and a large number of bacterial sources will be hidden in the leaves and phloem. Many bacteria spread to the leaves and roots along with the rain. In the cause of various diseases. What are the effective measures to take? I. Drainage drainage in time to prevent waterlogging. There is no attention to drainage, and there are no drainage facilities, especially some low-lying orchards, and orchards that often cause poor drainage after heavy rainfall and are prone to damage, and promptly eliminate water from orchards to promote the reduction of groundwater levels. Orchard humidity, enhance fruit tree plant resistance, reduce disease occurrence. Young orchards need to open deep gutters so that the gutters can communicate with each other, and the rain stops to promote the steady growth of roots. Second, fertilization. After heavy rains, decomposed and thinned human fecal urine is suitably added in orchards and nurseries, and 0.5% urea or 0.5% potassium dihydrogen phosphate aqueous solution can also be used for extra-root dressing, which can effectively improve the resilience of fruit trees. The increase of nitrogen fertilizer in the orchards with more rainy days and less sunshine can promote the photosynthesis of fruit trees, reduce the nitrogen starvation of fruit trees, and reduce the loss of fruit production. Fruit trees that have passed the picking period cannot be ignored. To protect it, you cannot influence the harvest in the coming year. Third, appropriate spraying, prevention of disease in advance. After strong winds and heavy rain showers, the branches, leaves, and roots of fruit trees become fragile and susceptible to infection by bacteria. At this time, it should be applied 300 times in loquat fruit, 600 times in Woolfin, 1000 times in garlic oil, and spray on silicone leaf. Destruction of cells, providing nutrients such as trace elements, direct bactericidal while the active ingredients absorbed by the leaves can be transmitted to the root system, killing bacteria in the root system. The point to note is that if it rains within 4 hours after application, it needs to be re-sprayed. Spray 2 or 3 times, each time between 5 and 7 days.
