How to manage peach orchard in summer?

How to manage peach orchard in summer? Please introduce the summer management of the peach orchard can refer to the following methods: first, look at the tree fertilization: in late May, apply fertilizer to the peach trees with more fruit this year and weaker tree potential. On the contrary, the peach trees with less fruit and more prosperous trees do not apply fertilizer. When fertilizing, dig a circular fertilization ditch about 1 meter long and 0.25 meters deep and 0.25 meters wide at the dripping place of the tree crown. For adult fruit trees, each tree was fertilized with 40-50 kg of water fertilizer, 0.3-0.4 kg of ammonium phosphate (or 0.25 kg of urea, 0.5-0.8 kg of superphosphate) and returned to the soil to cover the nest. The small trees were fertilized in half, and the peach trees were fertilized outside the roots, and 0.1% green Fenwei No. 1 foliar fertilizer (or 0.2% potassium dihydrogen phosphate and 0.3% urea mixed fertilizer solution) was sprayed once every 15-20 days, 4-5 times in a row. Do a good job in the drainage of Taoyuan, especially the low-lying Taoyuan, dig the main ditch and back ditch to 0.5 meters deep and 0.3 meters wide respectively, in order to lower the groundwater level and benefit the growth of peach trees. Third, summer pruning: summer pruning of peach trees from May to June. ⑴ wiping buds and heart-picking: wipe off the long buds in the crown and the competitive buds and twin buds under the cut, and pick the heart when the new shoots grow to 50-60 cm. ⑵ branch pulling and twisting: for upright peach trees with prosperous growth, the methods of pulling branches, hanging branches and supporting branches are adopted to increase the angle of the main branches and ease the tree potential. At the same time, twist the upright long branches and other strong long branches 180 degrees, but do not twist them off, so that they grow upward to grow horizontally, so as to turn the long branches into fruiting branches. ⑶ spraying hormone: when the secondary branch of the peach tree is about 60cm, spraying 15% paclobutrazol wettable powder can effectively control its growth and promote flower bud differentiation. Fourth, prevention and control of diseases and insect pests: from May to June, 80% anthrax Fumei or 75% chlorothalonil or carbendazim were sprayed on the crown for 3 times continuously to control gum disease, anthracnose and so on. For the trees that have been glued, scrape off the disease spots first, and then add methyl topiramate wettable powder to edible vinegar or smear the affected area with 402 sterilization solution. At the same time, the tree crown sprayed 2-3 times 50% enemy kill 1500 times liquid, 20% aldicarb or propofol 1200 times solution and other mixed solution to control peach borer, aphids, peach small (or pear small) heart borer and so on. Fifth, ploughing and weeding: on a sunny day in summer, artificial weeding is used in peach orchards with intercropping crops, and weeds are buried in the crown dripping place, or weeds are covered under peach trees, and the mixture of glyphosate (Roundup) and herbicides can also be sprayed in peach orchards, which plays a covering role after weeds die, which is beneficial to moisturizing and drought resistance, turning into the soil in autumn to increase soil organic matter.
