Problems solved by technology

Its existence can affect and effectively regulate the growth and development of plants, including a series of plant life processes from cell growth and division to rooting, germination, flowering, fruiting, maturation and shedding. Among them, abscisic acid has the function of inducing and promoting rooting. It is a key factor to balance the metabolism of plant endogenous hormones and related growth active substances. It has the ability to promote plants to absorb water and fertilizer in a balanced manner and coordinate metabolism in the body. It can be used as a raw material for the preparation of plant growth regulators to effectively regulate plant roots / shoots and Vegetative growth and reproductive growth play an important role in improving the quality and yield of crops. However, the currently disclosed plant growth regulators for promoting root growth such as: naphthaleneacetic acid, indoleacetic acid, sodium nitrophenolate, paclobutrazol, etc., mainly It is to promote the growth of the main root or lateral root, and it is not significant enough to promote the vitality of the root system, that is, the growth promotion of the root hair area

Abstract

The invention provides a plant growth regulating composition and a preparation and an application thereof; the plant growth regulating composition provided by the invention includes abscisic acid and polyamino acid, wherein polyamino acid is one or more of polyaspartic acid, salts of polyaspartic acid, polyglutamic acid and salts of polyglutamic acid; through compounding of abscisic acid and polyamino acid, and through controlling the amount ratio of the two components, the obtained compounded plant growth regulating composition has a cooperative synergism effect.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a plant growth regulating composition and its preparation and application. Background technique [0002] The root is an organ developed by plants to adapt to life on land during the long-term evolution process. Its function is not only to fix the aboveground part of the plant in the soil, but also to absorb water and nutrients needed for plant growth from the soil, and to carry out organic compound synthesis. Synthesis, transformation, storage and delivery of nutrients. Whether the root system is developed or not means strong and long-lasting vitality for plants. The most active part of the root system to absorb water from the soil is the root hair area, and the most active part to absorb minerals is the root cap With the apical meristem and the root hair area, various ions in the soil are first adsorbed on the root surface, and then enter the cell through the cell membrane through ener...
