Multifunctional growth regulator composition for peach trees

Abstract

The invention relates to a multifunctional growth regulator composition for peach trees and belongs to the field of plant growth regulation. The multifunctional growth regulator composition comprises, by weight, 4-11 parts of gibberellin, 5-10 parts of pimacol, 8-22 parts of diethyl aminoethyl hexanoate, 20-40 parts of auxiliaries and 33-50 parts of additives, wherein the auxiliaries refer to one or more of a fruit expander, a sugar increasing substance, a drought-resistant and water-retaining agent, a flower bud differentiation agent, ferrous sulfate, magnesium sulfate, vitamins and amino acids, and the additives refer to one or more of calcium carbonate, bentonite and kaolin. The multifunctional growth regulator composition for the peach trees has the effects on resisting adverse factors and synergy through synergism through all components and has a variety of efficacy without side effect.

Description

technical field [0001] The invention relates to a high-efficiency multifunctional peach tree growth regulator composition, which belongs to the field of plant growth regulation. Background technique [0002] Plant growth regulators are exogenous non-nutritive chemical substances aimed at target plants, which can usually be transmitted to the site of action in the plant body, and can promote or inhibit certain aspects of its life process at a very low concentration. Each plant growth regulator has a specific purpose, and can produce a specific effect on the target plant only under specific application conditions (including external factors). By using different types and different concentrations of exogenous hormones or plant growth regulators, the stress resistance and adaptability of plants can be improved, the photosynthetic efficiency of plants can be improved, the balance between plant vegetative growth and reproductive growth can be improved, and nutrition can be transfe...

AI Technical Summary

Problems solved by technology

This method can make the young fruit grow rapidly, but because the application of the agent is easy to be uneven, the pear fruit is prone to low-quality fruits such as deformed fruit, stiff fruit, and uneven surface.

In addition, although the fruit swelling factor has a significant effect on fruit enlargement, there are still some problems: (1) the produced fruit has low sugar content, poor flavor, and serious iron head disease; (2) the fruit stalk is easy to burn, so Increased the problem of mechanical fruit drop; (3) cause the annual physiological defoliation of peach trees 2-3 times, reduce the total photosynthetic output of the tree body, the quality of branches and buds is poor, and the formation of flower buds is few, resulting in late flowering in the next year, small flowers and small fruits (4) the stalk smear method is cumbersome to operate and requires a large amount of labor

Compared with smearing pectin on fruit stems, the spraying method of nutrient elements and plant growth regulator mixture saves labor and trouble, but, due to the small amount, it cannot promote the overall growth of roots, stems, leaves, flowers and fruits, and often fails to achieve the desired effect
