Plant growth regulator composition

Abstract

The invention discloses a plant growth regulator composition, which is prepared from the following components in parts by weight: 0.001%-1.0% of brassinolide, 0.3%-20% of gibberellin (one of GA3, GA4, GA7 or GA4+7), 0.005%-5.0% of S-abscisic acid, 1.0%-3.0% of a synergist oat polypeptide, 1.0%-5.0% of a synergist Isoimperatorin, and the rest of auxiliary materials such as conventional auxiliaries, solvents, emulsifiers, wetting dispersants or surfactants and the like. According to the invention, the absorption effect of plants is greatly improved, fruits are promoted to expand and premature, the yield-increasing and quality-improving effects are obvious, and especially the effects of improving color, sugar degree and appearance glossiness are more obvious; and the labor intensity that S-abscisic acid must be used for fruit soaking or fruit spraying to promote coloring is relieved, and the side effect that leaf surfaces are yellowed and fall off due to the fact that S-abscisic acid is sprayed to whole plants is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural growth regulators, in particular to a plant growth regulator composition containing brassinolactone, gibberellin, S-induced antibiotic and a synergist and its application. Background technique [0002] Plant growth regulators are artificially extracted and synthesized according to the structure, function and action principle of plant hormones. They can change the synthesis, transportation, metabolism and action of hormones in plants, thereby regulating plant growth and physiological functions. A large class of chemical substances. Auxins, gibberellins, ethylene, cytokinins, abscisic acid, brassinolides, etc. have been found. Plant growth regulators can promote or inhibit the growth and development of plants at relatively low concentrations. So far, plant growth regulators have been more and more widely used in the production of crops, fruit trees, and vegetables. [0003] At present, many p...

AI Technical Summary

Problems solved by technology

[0003] At present, many plant growth regulators used alone often fail to achieve the desired effect. The disadvantages of single-dose application of plant growth regulators are: the biological activity is relatively single, the growth regulation effect is relatively low, and the usage amount (or use concentration) is relatively large. And generally can only play a role in regulating the growth of crops in a certain growth period

[0007] Oat polypeptide has excellent moisturizing properties, accelerates cell proliferation, promotes cell and plant metabolism, and activates cells. It is better than the control in terms of surface finish and water retention of grapes, and the storage time is also extended.
