First, bagging must be completed in the middle of June, bagging work must be sprayed protective and therapeutic fungicide before bagging.
Second, fertilizer and water management
Topdressing: Dressing in June is particularly important. In this period, top dressing should be based on quick-acting fertilizers, with potash fertilizer, nitrogen fertilizer, and auxiliary phosphate fertilizers highlighted. The key period of flower bud differentiation should be stepped up as soon as possible. The purpose is to enrich the top buds and increase the quality of flower buds next year.
Foliar Spraying: In mid-June, the whole tree was sprayed with 300-fold amino acids 1 or 2 times, 6000 times with Steadcope, 1,000 times with heavy calcium or 800 times with calcium lactate, or 800 times with Galesia to supplement nutrition and promote flower buds. Differentiation, reduce bitter pit, pox spot disease and other calcium deficiency disorders.
Underground fertilizer: topdressing nitrogen fertilizer in June is very important, it is the maximum fertilizer efficiency of nitrogen fertilizer. Mainly available nitrogen fertilizer, appropriate application of phosphate fertilizer and potash fertilizer.
Third, the orchard-covered straw covers the surface of the orchard soil, which can reduce the intensity of sunlight irradiation, reduce the temperature in the summer, and reduce the evaporation of ground water. Improve the growth environment of fruit trees and the microclimate of orchards, promote the growth and development of underground and above-ground parts of fruit trees, and improve fruit yield and quality.
Fourth, summer trim
Thinning: It is necessary to promptly eliminate excessive and excessively dense branches.
Ring cut: Continue cutting around Wangshu and Wangzhi to control growth and promote flower bud differentiation.
Twisting tip: twisting the shoots on the branches that have been half-wooded and over the branches, twisting branches and branches can also be performed at the same time.
Take branch softening: After mid-June, after the spring shoots are stopped, the branches can be softened by 1-3 years old shoots. The method is: from the base to the tip, the upright branches are manually twisted from the upright state to the horizontal or down state.
Topping the leaves: The time of picking the leaves to the leaves should be carried out every time the vegetative growth is close to the length, ie in mid-late and late July.
Sapling branching: Each orchard must determine the branching angle of branches according to the actual situation so as to control the extension of growth and promote the formation of flowers as soon as possible.
V. Pest Control
Ringworm disease: Branches of stems and a variety of dead bacteria on dead branches have entered a period of large numbers of spore formation. If there is rain or high humidity, a large number of spores are emitted to infect the fruit, leading to fruit carrier. Spraying pesticides in time after rainfall is the key to reducing late-stage rotting. Distinctive deciduous disease: In late June, if there is more rainfall, the young shoots of the disease may be infected by pathogens, and the disease will be severe in July and August. The Marshal should pay close attention to the orchard and spray it in time to prevent and cure the disease.
Hawthorn Leafhopper: Fallen leaves in the middle and late June. Before and after wheat harvest, we must pay attention to doing a good job of prevention and control.
Peach fruit borer: Overwintering larvae are the peak of excavation in the middle and late June. There is close relationship between the emergence of larvae and rainfall, and the control effect of pesticide application is better when larvae are unearthed.
Rot Disease: From June to July, it is a critical period for the control of apple tree rot.
