Summer is an important period for the growth of peach branch shoots and fruit enlargement. Strengthening management of peach trees is the key to increase production and high yields next year.
First, see the tree fertilization. In late May, topdressing peach trees with more results and weaker tree vigor was applied this year. Conversely, peach trees with less fruit and more vigorous tree vigor 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 were planted, and each plant had 40-50 kg of fertilizer and acquaintance for livestock and poultry, 0.3-0.4 kg of ammonium phosphate (or 0.2 kg of urea, and 0.5-0.8 kg of superphosphate) were fertilized to cover the soil. The trees were halved and fertilized outside the roots of the peach trees. The foliar spray was applied with 0.1% Fenfen No. 1 foliar fertilizer (0.2% potassium dihydrogen phosphate and 0.3% urea mixed fertilizer solution) every 15 to 20 days. Spray 1 time, 4-5 times in a row.
Second, 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 cleared 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.
Third, summer trim. Peach trees are pruned in summer from May to 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, turning the branches of the appetite into 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, control pests. From May to June, 80% of anthrax or 75% of chlorothalonil 800 times, or 800-1000 times of carbendazim was sprayed on the canopy 3 times continuously to prevent fluidosis and anthrax. 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. .
Fifth, weeding and 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. It is also possible to spray glyphosate (Nongda) in the peach orchard. Gram-free herbicide mixture liquid, weeds cover from the dead, is beneficial to moisturizing and drought, fall into the soil in autumn, increase soil organic matter.
Progesterone is a female hormone that is produced in the highest amount after ovulation. Progesterone is very valuable during IVF cycles, and can also be an important part of preventing miscarriage in older female animal and in female animal with a history of miscarriage.
