Fruit tree canopy closure disease rescue method

Abstract

The invention relates to a fruit tree canopy closure disease rescue method, and relates to the technical field of planting. The method comprises the following steps: budding water is irrigated before budding, and budding top dressing is applied at a same time; during a fruiting period, flowers and fruits are thinned, and a protection agent, a fungicide and an insecticide are applied; fertilization is carried out twice in autumn; fruits are bagged; bags are removed, and the fruits are colorized; pruning is carried out in the four seasons, and lime sulfur is applied. With the method provided by the invention, fruit trees with a canopy closure problem can be rejuvenated, and fruit tree canopy closure disease can be effectively solved. With the method, fruit tree full productive period can be maximized; fruit nutrients are comprehensive; fruit taste is good; and fruit farmer economic benefit is improved. The method is convenient, feasible and economical. The method can be implemented by every fruit farmer, and is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to a method for rescuing fruit tree "depression" and belongs to the technical field of planting. Background technique [0002] The planting of fruit trees such as apples and pears is one of the important industries for farmers to get rich. After years of growth, fruit trees have entered the aging stage. Planting efficiency directly affects the income of fruit farmers. The branches of fruit trees suffering from "depression" are thick, airtight and light-proof, resulting in small fruit size, poor sales, and price increases. According to the previous method, it is to cut down old trees and plant new ones. However, fruit farmers are reluctant to cut down their own "money tree", because new fruit trees have to wait 3 to 4 years before they can enter the fruiting and full fruiting period. [0003] At present, researchers have proposed a renewal and rejuvenation method to transform the "canopy closure" of fruit trees, that is, on the b...

Problems solved by technology

However, cultivating new branch groups requires technical support, is difficult for most fruit growers to implement, and requires a lot of manpower and material resources, and the cultivation cycle is long, which increases the economic burden for fruit growers and restrains the income of fruit growers.
