High-yield cultivation method for fruit trees

Abstract

The invention relates to a high-yield cultivation method for fruit trees and aims to solve the problem that coordination and unity of early yield, high yield and high quality are hard to achieve in current fruit tree cultivation. The method includes: selecting arbor rootstock long branch type fruit trees for close planting, selecting appropriate axillary buds, promoting budding and sprouting, and smearing bud eye sprouting accelerant on the axillary buds on two sides and at the back of branches when the new branches grow to 30-40cm so as to promote the axillary buds to differentiate into flower buds and flower branches; in August to September of the year when branches sprouts from fruit tree bud seedling stems, performing branch taking and softening on the sprouted branches in prior to angle opening, wherein the angle opening positions are 2-5cm away from branch bases, and the opened angle ranges from 100 degrees to 120 degrees. By the method, fruit tree flourishing, yield and quality are coordinated, nutrition distribution is changed, nutrition growth is changed into reproduction growth, a large amount of high-quality flower buds are formed, early yield is promoted, and fruit yield and quality are increased. In addition, the method is simple to operate, small in crown size, concentrate in fruiting, and capable of reducing manpower of each link.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a high-yield cultivation method for fruit trees capable of realizing early harvest, high yield and high yield. Background technique [0002] Fruit trees such as apples, sweet persimmons, and pear trees have a large area of ​​cultivation in my country. In terms of pruning techniques for these types of fruit trees, there are short cuts, long releases, thinning branches, retraction, topping, twisting tips, straightening branches, table shears, hat shears, pigtailing, girdling, girdling, etc. Pruning method, steps are loaded down with trivial details. In production practice for many years, most fruit growers are difficult to master and implement proficiently, and then can't effectively manage fruit tree production. At present, most orchards still adopt the plastic cultivation management method of trunk evacuation and layering, and the spacing between plants and rows ...

AI Technical Summary

Problems solved by technology

[0003] In recent years, people continue to explore new management models for fruit tree cultivation and have made some progress: arborization and dense planting of fruit trees have appeared, and tree types such as improved spindle and slender spindle have also appeared. For example, Yiyuan County, Shandong Province Wang Chunzhen, a fruit farmer in Yanya Township, explored and formed the apple tree weeping willow pruning technology in practice, which solved some technical problems to a certain extent, but the planting density was still unsatisfactory (the spacing between plants and rows was 3m×4m), which had a negative impact on the overall yield of apples. The improvement is limited, and in the process of pruning, it is necessary to implement operations such as bud wiping, cutting buds, and pruning branches. It takes 3 to 4 years for the final pruning to take shape. Moreover, the buds that are constantly erased and the prosperous branches that are cut off consume a large amount of nutrient resources in the fruit tree, and the above-mentioned pruning techniques have not been able to transform and utilize these valuable nutrient resources from the source.
