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.

Embodiment Construction

[0019] Unless otherwise defined, technical terms used in the following embodiments have the same meanings as commonly understood by those skilled in the art to which the present invention belongs. The test reagents used in the following examples are conventional biochemical reagents unless otherwise specified; the experimental methods are conventional methods unless otherwise specified.

[0020] The present invention will be described in detail below with reference to the embodiments.

[0021] The test site was Jizhou District, Tianjin City. The test variety was Xianyu 335, which was sown on May 1, 2020. The experimental group was divided into five groups, namely the experimental group and the control group. Each group was set up with three replicates. The group was treated with clean water, and the plant growth regulator in the experimental group was prepared according to the following formula:

[0022] Experimental group 1:

[0023] Active ingredient: 10 copies of ethephon...

Abstract

The present invention provides a plant growth regulator for promoting corn grain filling and its application, including the following effective active ingredients and auxiliary synergistic ingredients, wherein the effective active ingredients include: 1-30 parts of ethephon; 1.5 parts; the auxiliary and synergistic ingredients include: 1-5 parts of fatty glucosinolates; 1-5 parts of calcium salts; and 1-5 parts of magnesium salts. The plant growth regulator of the invention can significantly improve the grain filling speed of corn grains, can significantly shorten the grain filling time, and reduce the production cost; achieve the effect of increasing production.

Description

technical field [0001] The invention belongs to the field of plant growth regulators, in particular 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 fodder crops in my country, and it is also an important chemical, fuel and pharmaceutical raw material. Studying the growth process of maize and improving the final yield of maize by means of manual intervention is one of the effective means to solve the shortage of resources and solve the continuous increase of domestic demand for maize, which has far-reaching significance. Crop chemical control cultivation is an important application technology of cost saving, efficiency improvement and yield increase in planting industry, and it has been widely used in agricultural production at present. In recent years, the application of plant growth regulators has attracted more and more attention as a means of regulating crop growth and ...
