A kind of fruit tree growth regulator pharmaceutical composition and application thereof

Abstract

The invention belongs to the field of plant growth regulation, and in particular relates to a plant growth regulator pharmaceutical composition for regulating the growth of fruit tree tops. The composition includes the following effective ingredients for regulating plant growth: prohexadione calcium, sodium nitrophenolate / aminohexanoate / sodium naphthalene acetate / triacontanol / brassinolide / 6-benzylaminoadenine; In terms of components, the composition is diluted with water to a concentration of 150-800 mg / kg for regulating the growth of fruit trees. Compared with the prior art, the medicament composition provided by the present invention solves the problem that it is difficult to synchronize the shoot control, flower promotion and safe production increase in the process of fruit tree tip control; Ratio, inducing nutrient elements to concentrate on the fruit, increasing the rate of flowering and fruit setting, inhibiting vegetative growth and promoting reproductive growth, the effect of increasing yield is obvious, and the quality of fruit is significantly improved.

Description

technical field [0001] The invention belongs to the field of plant growth regulation, and in particular relates to a plant growth regulator pharmaceutical composition for regulating the growth of fruit tree tops. Background technique [0002] In order to increase the yield of artificially cultivated fruit trees, high-density planting is often used. It is difficult to control the size of the canopy, which affects the ventilation and light transmission of the tree, which is not conducive to photosynthesis and the distribution of carbohydrates to the fruit. Therefore, the vegetative growth of the tree is coordinated. The relationship between reproductive growth and reproductive growth is one of the important prerequisites for high fruit yield. At present, artificial pruning and plant growth regulators are mostly used in production to control shoots and promote flowers, and increase fruit tree yield. However, the manual pruning method requires a lot of labor and requires relati...

Problems solved by technology

[0004] The application of conventional plant growth retardants such as paclobutrazol, uniconazole, chlormequat, biju, ethephon and other plant growth regulators has always had less and less obvious drug effects, larger doses, high residues, high Many problems such as cost, such as paclobutrazol, which is commonly used at present, can slow down vegetative growth and reduce the amount of new shoots, but it has a long residual period, poor environmental friendliness, and strict requirements on the concentration of use. If it is too low, it cannot achieve the effect of controlling shoots and promoting flowers. If 2,4-D or ethephon is used to regulate the growth of fruit tree tops, improper use will easily lead to yellow leaves, fallen leaves and large areas of fruit drop. affect the output

However, there is no relevant report that prohexadione calcium or its compound pharmaceutical composition is used to regulate the growth of fruit trees.
