Modifier for promoting plant rooting and sprouting, preparation method thereof and application

Abstract

The invention discloses a modifier for promoting plant rooting and sprouting and a preparation method thereof and belongs to the technical field of crop growth modifiers. The modifier comprises 3-8 parts of rhamnolipid surfactant and 5-15 parts of sucrose ester surfactant. Preferably, the modifier comprises 5 parts of rhamnolipid surfactant and 10 parts of sucrose ester surfactant. The modifier is prepared from, by weight parts, 3-8 parts of rhamnolipid surfactant, 5-15 parts of sucrose ester surfactant, 2-10 parts of compound bacteria powder, 30-60 parts of thoroughly-decomposed livestock excrement, 35-45 parts of fermented bean dregs, 30-50 parts of thoroughly-decomposed straw, 5-10 parts of potassium fulvic acid, 3-10 parts of dicalcium phosphate and 2-6 parts of zinc gluconate. The modifier can promote rooting and sprouting, enables branches and leaves to flourish, improves yield and is low in production cost, simple in preparation process and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of crop growth regulators, and in particular relates to a regulator for promoting plant rooting and germination, a preparation method and an application. Background technique [0002] The root system, as the crop's overall water and fertilizer resource capturer and an important organ for synthesizing various physiologically active substances, is closely related to soil moisture, nutrient distribution, migration and consumption. The ability to absorb and utilize water and nutrients directly affects the establishment of the aboveground canopy of crops, the distribution of assimilates and the formation of final yield. Optimize the root system function, regulate the growth and development of the whole plant through the root system, so as to achieve the purpose of high yield, high efficiency and high quality. [0003] Different water and fertilizer measures have obvious regulatory effects on the physiological ac...
