Summer is an important period for the growth of peach tree branches and fruit enlargement. Strengthening the management of Taoyuan is the key to the increase in production and the high yield in the next year. First, see the tree fertilization: In late May, more results this year, peach trees with weaker vigor exert a top dressing. Conversely, peach trees that are less fruitful are not fertilized. During fertilization, a circular fertilization ditch with a length of about 1 meter, a depth of 0.25 meters and a width of 0.25 meters was fertilized at the dripping point of its crown. Adult fruit trees are planted, and 40-50 kilograms of fertilizer and acquaintances are used for each plant, and 0.3-0.4 kg of ammonium phosphate (or 0.25 kg of urea and 0.5-0.8 kg of superphosphate) are applied to fertilize the soil. Small trees are used for half-fertilization, while peaches are top-dressed and the leaves are sprayed with 0.1% Phytonite No. 1 foliar (or 0.2% KH2PO4 and 0.3% urea mixed fertilizer) every 15 to 20 days. Spray 1 time, 4-5 times in a row. 2. Drainage and flood prevention: Peach trees are afraid of embarrassment. In June-July, it is a rainy season. The main ditch and back ditch and sinking sand mound should be frequently dredged and cleaned up. Do a good job of Taoyuan drainage, especially the low-lying Taoyuan, dig the main ditch and back ditch to depths and widths of 0.5m and 0.3m, respectively, to lower the groundwater level, which will benefit the growth of peach trees. 3. Summer pruning: Summer pruning of peach trees in May-June. (1) Tossing the tips of the buds: Wiping off the buds of buds in the canopy and the buds and twin buds under the clippings. When the new shoots grow to 50-60 cm, they will be picked up. (2) Pulling branches and twisting shoots: To erect peach trees that grow more prosperously, take the methods of pulling branches, hanging branches, and spreading branches, and increase the angle of the main branch to ease the tree potential. At the same time, turn the upright leggy branches and other prosperous branches 180 degrees, but do not twist them so that they turn from upward growth to horizontal growth, causing the leggy branches to turn into fruiting branches. (3) Spraying hormones: When the second branch of peach trees grows to about 60 cm, a 15% paclobutrazol WP can be sprayed 500 times, which can effectively control its growth and promote flower bud differentiation. Fourth, pest control: From May to June, with 80% anthrax or 75% chlorothalonil 800 times, or carbendazim 800-1000 times continuous spray canopy 3 times to prevent fluidosis, anthrax and so on. For trees that have been flowed, scrape off the lesions first, then add vinegar to the thiophanate-methyl WP or smear the affected area with 100 times sterilized with 402. At the same time, the canopy was sprayed 2-3 times with 50% adversary 1500 times liquid, 20% anti-influx, or 1.25 times liquid of purofurazone, etc., to prevent and control peach aphid, aphid, peach (small pear), etc. . V. Cultivated weeding: In summer sunny days, artificial weeding is applied to the peach plantation in the intercrop plant, and weeds are buried in canopy drips, or weeds are covered under peach trees, and glyphosate can also be sprayed in the peach orchard. (Dongda) and Keluozhi herbicide mixed liquid, weeds play a covering role after withered, it is beneficial to moisturize and resist drought, fall into the soil in autumn, increase soil organic matter.
