Agent for preventing fruit dropping of peach trees and preparation method thereof

Abstract

The invention belongs to the technical field of plantation of fruit trees, and especially relates to an agent for preventing fruit dropping of peach trees and a preparation method thereof. The agent for preventing fruit dropping comprises the following compositions in parts by mass: 15-20 parts of calcium dihydrogen phosphate, 5-10 parts of biological calcium, 2-4 parts of boric acid, 5-9 parts of naphthylacetic acid, 5-10 parts of a bactericide, 2-4 parts of sodium lignin sulfonate, 3-7 parts of composite amino acid, 1-4 parts of sodium salicylate and 800-1000 parts of deionized water. The beneficial effects obtained by employing the technical scheme comprise that the agent for preventing fruit dropping and applied to peach trees is capable of supplying sufficient nutrients for peach trees, helping to guarantee reproduction growth balance of peach trees and normal growth of fruits, and avoiding generation of the phenomenon that peach drops in advance; the output of peach is improved by 80% or more; and also peach is large, sufficient in water content, good in mouthfeel and well received by consumers.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, in particular to an anti-dropping agent for peach trees and a preparation method thereof. Background technique [0002] Nutritious, peaches are a favorite summer fruit. During production, due to various reasons, peaches will drop early. Peach trees lose fruit physiologically, those who fall first are mostly those with poor pollination and fertilization, and those who fall later are because the nutrients stored in the tree body have been exhausted at this time, and the number of new leaves is insufficient. Failure to meet the needs of young fruit development resulted in a large number of fruit drop. [0003] There are many reasons for the fruit drop of peach trees. The daytime temperature is higher than 33°C, and the nighttime temperature is lower than 10°C; the tree leaves too much light and deteriorates; adjacent fruits collide with each other; water and fertilizer management is ou...

Problems solved by technology

[0004] At present, when people apply fruit-setting fertilizers to peach trees, they generally use manure, bean cakes, urea, etc. to fertilize. Although they can also increase production to a certain extent, the various nutrients in the fertilizers are far from reaching The nutritional needs of peach trees, and the application of immature chicken manure or ammonium bicarbonate and other chemical fertilizers, the release of a large amount of ammonia gas has harmed the peach trees, resulting in yellow leaves, few flowers, and few fruits. The peaches produced are small in size and heavy in weight. Lightweight, slow growth, fruit trees are prone to various fruit tree diseases due to long-term lack of fertilizer
