How to manage planting peach trees in greenhouse?

How to manage planting peach trees in greenhouse? Please introduce the management of planting peach trees in greenhouse with reference to the following methods: first, anti-sprouting and pruning. Greenhouse peach tree sprouting period, timely removal of unreasonable sprouting. After flowering, the dense branches, overgrown branches, erect branches, shadow branches and cross branches should be removed in time according to the situation. The fruit tree retracted 4-6 weeks before harvest, and only one new shoot was left in front of the fruit shoot, which could be cut off properly. The structure of the tree should be adjusted to have uniform flower spots under the tree at noon. Second, control the crown. Each backbone branch retains a suitable direction of vigorous new shoots. When the upward growing fruit platform secondary shoots grow to 10 large leaves, they are continuously coring and wiping lateral buds to form blind branches, and other prosperous new shoots are stained with 50-fold 15%PP333. These measures can effectively control the vigorous growth, increase the yield per plant, and reduce the physiological and pre-harvest fruit drop. Third, pick leaves and hang branches. 20 days before fruit picking, remove the light-affected leaves of the fruit and hoist the drooping branches to the light-receiving surface to promote the coloring of the fruit. Four or six weeks before harvest, hanging or pulling the drooping fruit branches above the crown with a rope can greatly improve the light conditions of the tree and increase the coloring of the fruit. Fourth, spray plant growth regulators and fertilizers. Spray LXL Guoling or fructins containing 1.8%GA4+7 and 1.8% 6-benzyladenine once at flowering stage and 2 weeks after anthesis to increase fruit setting rate and promote fruit expansion. About 10 days after peach blossom, spray 0.5% urea and 0.2% potassium dihydrogen phosphate mixture 2 times. Spray should be carried out in the evening without wind or on cloudy days, once every 2 weeks. Fifth, topdressing and watering. In the greenhouse, the peach fruit in the hard core stage and the fruit expansion stage were topdressing once, and each plant was topdressing 30 grams of urea and 30 grams of potassium dihydrogen phosphate. Combined with fertilization, each is watered once, and the amount of watering depends on the soil moisture. Sixth, prevention and control of diseases and insect pests. ① disease. The main diseases are peach bacterial perforation, mildew spot perforation and brown spot perforation. Spraying Baume 5 degree stone sulfur mixture on the tree before sprouting can reduce the infection source of bacteria and the overwintering base of pests. After the root disease was found, the root was irrigated with Duoxiaoling solution in time. ② pest. Peach aphid, pink aphid and peach tumor aphid are mainly harmful to leaves and tender shoots. Commonly used pesticides are aphid lice once clean, quick killing and enemy killing and so on. ③ is used to prevent diseases and pests after fruit picking. After fruit picking, peach trees in greenhouse should also strengthen the prevention and control of diseases and insect pests, combined with foliar fertilization, in order to prevent abnormal defoliation in early autumn and promote leaf photosynthesis efficiency and photosynthate accumulation. thus, the poor quality of flower bud differentiation and the degeneration of pistil caused by the lack of storage nutrients can be overcome.
