Composition for increasing fruiter fruit setting rate and application thereof

Abstract

The invention provides a composition for increasing fruiter fruit setting rate and relates to the technical field of plant regulators. The composition comprises, by weight, 1-5 parts of diethyl aminoethyl hexanoate and 0.2-0.5 part of gibberellin. By spraying a preparation comprising the composition onto fruiters, fruit dropping rate of pear can be lowered from higher than 5% to about 1% while that of peach can be lowered from about 15% to about 10%, fruit dropping rate of plum can be lowered from 40% to 20% while that of two-ovary plum among the plum is lowered from 99% to 90%, so that fruitdropping rate of the fruiters is lowered remarkably, and fruit setting rate of various fruiters is increased.

Description

technical field [0001] The invention belongs to the technical field of plant regulators, and in particular relates to a composition for improving the fruit setting rate of fruit trees and an application thereof. Background technique [0002] Plant growth regulators are a class of pesticides used to regulate plant growth and development, including synthetic compounds with similar effects to natural plant hormones and natural plant hormones extracted from organisms. Ordinary plant growth regulators have a single component and a narrow range of use, resulting in a single function. [0003] For target plants, plant growth regulators are exogenous non-nutritive chemical substances, which can usually be transmitted to the site of action in plants, and can promote or inhibit certain links in their life processes at very low concentrations, making them To meet the needs of human development. Each plant growth regulator has a specific purpose, and the application technology require...

[0004] Moreover, the existing regulators for preserving flowers and fruits for fruit trees are mostly multi-component products, and have different concentrations or methods for different tree species. However, there are no reports about the regulators for preserving flowers and fruits of binary compounds at present.
