How to manage the peach orchard in summer?

How to manage the peach orchard in summer? Summer is an important period for branch growth and fruit expansion of peach trees. Strengthening the management of peach trees is the key to increase production in the current year and high yield next year. First, look at the trees to fertilize. In late May, topdressing was applied to peach trees with more fruit and weaker tree strength this year. On the contrary, the peach trees with less fruit and more prosperous trees are not fertilized. 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 water fertilizer for mature human livestock and poultry, and 0.3-0.4 kg ammonium phosphate (or 0.2 kg urea, 0.5-0.8 kg superphosphate) was added to the soil to cover the nest. The small trees were fertilized by half, and the peach roots were fertilized at the same time, and 0.1% green Fenwei No. 1 foliar fertilizer (0.2% potassium dihydrogen phosphate and 0.3% urea mixed fertilizer solution) was sprayed once every 15-20 days for 4-5 times. Second, drainage and waterlogging prevention. Peach trees are afraid of waterlogging, June-July is a rainy season, should often dredge and clean the main ditch and back ditch, sand sinking and so on. 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. Peach trees are pruned in summer 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 prosperous long branches 180 degrees, but do not twist them off, so that their upward growth is turned into lateral growth, and their overgrown branches are turned 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 pests. From May to June, the canopy was sprayed with 80% anthrax Fumei or 75% chlorothalonil or carbendazim 1000 times continuously to prevent and 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, or a mixture of glyphosate (Roundup) and gram untracked herbicides can be sprayed in peach orchards. Weeds play a covering role after death, which is beneficial to moisturizing and drought resistance, turning into the soil in autumn to increase soil organic matter.
