Plant growth regulator for promoting filling of corn kernels, and application thereof

Abstract

The invention provides a plant growth regulator for promoting corn kernel filling and application thereof, the plant growth regulator comprises the following effective active components and auxiliary synergistic components, the effective active components comprise 1-30 parts of ethephon and 0.001-1.5 parts of phytoncide; and the auxiliary synergistic components comprise 1-5 parts of fat glucosinolate, 1-5 parts of calcium salt, and 1-5 parts of magnesium salt. According to the plant growth regulator provided by the invention, the filling speed of the corn kernels can be obviously increased, the filling time can be obviously shortened, and the production cost can be reduced; in addition, the plant growth regulator can improve indexes such as the number of grains per ear and the weight per hundred grains of the corn, so that the effect of improving the yield is achieved.

Description

technical field [0001] The invention belongs to the field of plant growth regulators, and in particular relates to a plant growth regulator for promoting corn grain filling and its application. Background technique [0002] Corn is one of the main food crops and feed crops in my country, and it is also an important chemical, fuel and pharmaceutical raw material. Studying the growth process of corn and increasing the final yield of corn through artificial intervention is one of the effective means to solve the shortage of resources and the continuous growth of domestic corn demand, which has far-reaching significance. Crop chemical control cultivation is an important cost-saving, efficiency-enhancing, and yield-increasing application technology in planting industry, and it is widely used in agricultural production at present. In recent years, the application of plant growth regulators as a means of regulating crop growth and development has received more and more attention. ...

Problems solved by technology

However, studies have shown that ethephon can dwarf corn plants after being used in corn, create a good plant shape, and effectively prevent corn lodging, but because ethephon is not conducive to grain development, it is an important factor that causes grain abortion. As a result, it is easy to make the ear shorter and thinner, the number of grains per ear is reduced, and the thousand-grain weight is reduced, resulting in reduced yield.
