How to manage peach trees in the rainy season? Please introduce the method of peach trees in rainy season can refer to the following methods for management: 1, drainage waterlogging peach trees are more sensitive to water, showing resistance to drought and fear of waterlogging. If there is stagnant water, the oxygen in the soil is insufficient, the respiration of the root system is blocked, the tree is weak, and if the heavy tree is dead, the water must be discharged in time. The peach orchard on the hillside uses contours to dig drainage ditches according to the tree potential. Flat orchards usually dig a drainage ditch between every two rows of trees, connect these ditches and drain water out of the peach orchard. In case of short-term stagnant water, clayey soil should be dried (after drainage, clean up the soil under the tree to keep the main root exposed for a few days, and then buried). 2. It is easy to infect diseases, such as anthracnose, brown rot, solid rot and soft rot, etc., especially when the fruit is near maturity. It can be sprayed with 1500 times of 80% methyl topiramate wettable powder or 50% carbendazim wettable powder and used alternately. At the same time, we should pay attention to the control of various pests, such as red spider, red-necked longicorn beetle, leaf moth, leaf roll moth, white star flower golden turtle and so on. Should pay attention to the weather forecast, timely spraying, such as 24 hours after spraying large-scale rainfall, should immediately re-spray, in order to ensure the effect of spraying. 3. Scientific fertilization in flood season should "eat less food for many times", especially in river beach and hilly thin land. Topdressing should use hole application or strip ditch application, mainly potassium fertilizer, accounting for more than 40% of the total fertilizer application, properly combined with nitrogen and phosphorus fertilizer. Can also be combined with spraying for extra-root topdressing, the concentration is generally 0.4% 0.5% potassium dihydrogen phosphate, 0.5% 0.1% calcium superphosphate, 0.3% 0.5% urea. 4. Reasonable pruning of early-maturing varieties can be pruned after fruit harvest, mainly cutting off the disease and insect branches, overgrown branches, crossed branches, overlapping branches and drooping branches in the crown, so as to ensure the light of the branches and facilitate the differentiation of flower buds. In the peach orchard with closed canopy, the disease is more serious, so the overdense branches and overgrown branches must be removed before ripening, so as to make the crown ventilated and transparent, resist the occurrence of diseases, and be conducive to coloring and ripening. However, it is not suitable to trim the fruit too heavily to avoid sunburn. The unfruited young trees are in the period of vigorous growth in the flood season, so we should do a good job in summer pruning to promote shaping and branch maturity. 5. The varieties with lower trunk and more open main branches, such as Okubo, after entering the full fruiting period, because of more fruit, the branches and fruits droop close to the ground, and when it rains for a long time, the fruits and branches and leaves are easy to be infected with diseases due to the influence of ground evaporation water. Before the flood season comes, the main branches should be lifted away from the ground to reduce the occurrence of diseases. 6. timely ploughing and weeding with high temperature and humidity in the rainy season is very suitable for the growth of weeds. If it is not treated in time, it will easily lead to weeds and aggravate the occurrence of diseases and insect pests.
