Abstract

The invention relates to a regulator for promoting growth of fruit tree flowers and a preparation method of the regulator, belongs to the technical field of fruit tree cultivation and aims to solve the problems of low yield of orchards in season and vigorously growing saplings, hormone residues on fruits and the like. The regulator for promoting the growth of the fruit tree flowers comprises components in parts by weight as follows: 1.2-1.8 parts of choline chloride, 0.6-0.9 parts of sodium bisulfite, 0.6-0.9 parts of potassium bicarbonate, 3.9-5.5 parts of paclobutrazol, 0.8-1.3 parts of uniconazole, 0.2-0.4 parts of 6-benzyladenine, 13.8-16.8 parts of monopotassium phosphate, 11.3-13.8 parts of zinc sulfate, 15.9-19.4 parts of boric acid, 2.4-3.7 parts of ammonium molybdate and 0.6-0.8 parts of a wetting dispersant. A preparation process of the regulator for promoting the growth of the fruit tree flowers is simple, low in cost and convenient to use, the regulator has remarkable shoot controlling, flower growth promoting and yield increasing effects, the hormone residues on the fruits are reduced effectively, the regulator has better social and economic benefits and has wide application prospect in open-ground cultivation, facility cultivation and potting cultivation of various fruit trees.

Description

technical field [0001] The invention relates to a fruit tree flower growth-promoting regulator and a preparation method thereof, belonging to the technical field of fruit tree cultivation. Background technique [0002] The top dominance of fruit trees and excessive nitrogen fertilizer lead to vigorous plant growth, imbalance between vegetative growth and reproductive growth, small number of flower bud differentiation and poor differentiation quality, which directly affect the yield and quality of fruit trees. In fruit tree production, agronomic measures such as topping, section pruning, branch pulling, circumcision, and girdling are usually used to suppress the dominance of the top of the fruit tree, keep the tree dwarfed, and promote flower bud differentiation, which play an important role in the high-yield cultivation of fruit trees. However, these technical measures require professional manual operations every year, and the labor intensity is high, especially the continuo...
