Method for solving biennial fruit bearing of citrus

Abstract

The invention discloses a method for solving biennial fruit bearing of citrus, which comprises the steps: (1) thinning flowers, to be specific, thinning to remove abnormal flowers and dense leafless flowers in the differentiation period of citrus buds, and spraying a flower thinning agent; (2) thinning fruits, to be specific, thinning fruits twice, thinning to remove dense and dysplastic malformedfruits in the late May for the first time, dense thinning to remove young fruits, diseased and infested fruits and mechanically damaged fruits in the early July for the second time, with the fruits uniformly distributed; (3) pruning, to be specific, selecting relatively strong branches, and cutting off shade branches and diseased and insected branches to balance tree vigor; and (4) applying fertilizers, to be specific, spraying trees and citrus leaves, and heavily applying organic fertilizers in the deep-turning fertilization process. The invention provides the method for solving the biennialfruit bearing of citrus by providing a mode of managing citrus in various periods.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, and more specifically relates to a method for solving the size and size of citrus. Background technique [0002] The purpose of cultivating citrus is to obtain high-yield, stable-yield, and high-quality fruits. However, the phenomenon of citrus large and small annual fruits generally exists in various production areas, resulting in large fluctuations in yield, decreased fruit quality, poor fruit uniformity, small fruit, sour taste, Rough oil cells, thickened fruit skin, and increased deformed fruit directly affect the economic income of fruit farmers. [0003] The main reasons for citrus to produce large and small annual results are as follows: [0004] 1. Types and varieties: Generally speaking, sweet oranges, grapefruits, lemons, etc. bear lighter fruit every other year, and citrus with wide skins is the most common. In the same category, different varieties have different fruit...

Problems solved by technology

[0008] 5. Improper cultivation technology measures: If too much fertilizer is applied, especially in small years, too much N fertilizer will cause excessive growth of branches, insufficient fertilization, and weak tree vigor; improper use of medicine will cause tree damage to the tree and affect the growth of branches and fruits. , aggravate the damage of diseases and insect pests, excessive construction, late harvesting and other measures can affect the flower bud differentiation of the tree body, forming large and small annual results

[0009] In the prior art, the size and size of citrus is regulated mainly through mechanical thinning of flowers and fruits or spraying of plant growth regulators, which is easy to cause mechanical damage and adverse effects on fruits, vegetables, etc., or the hormones in plant growth regulators affect the growth of fruit trees or fruits
