Problems solved by technology

[0003] Grain filling in rice is a complex and orderly dynamic process, including the regulation of sucrose-starch metabolism-related enzymes and their genes, as well as the regulation of plant hormones and their anabolism-related genes. The low conversion efficiency of sucrose to starch in the middle and later stages of the grain is the main reason for the poor grain filling of the weaker grains

Abstract

The invention discloses a chemical regulator for improving rice grain filling and filling, a preparation method and a use method thereof, and belongs to the technical field of plant growth regulators. The chemical regulator is mainly composed of salicylic acid, vitamin C, zinc sulfate, potassium dihydrogen phosphate, boric acid and an emulsifier, which can increase the thousand-grain weight of rice grains, increase the initial potential, maximum grain filling rate and average grain filling rate of rice grains , to shorten the time required to reach the maximum grain filling rate, thereby increasing the polished rice rate and the whole polished rice grain rate, reducing the imperfect and chalky grain rate of the grain, especially for the regulation of weak rice grains. In addition, the regulator of the present invention has easy-to-obtain raw materials for each component, is low in cost, has no toxic and side effects, and is simple to use and easy to realize. The preparation method of the chemical regulator for improving rice grain filling and filling provided by the invention has the advantages of simple process, simple and convenient operation, and easy industrial popularization and application.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulators, and in particular relates to a chemical regulator for improving rice grain filling and filling and a preparation method thereof. Background technique [0002] Food shortage is one of the most serious global problems in this century. In recent years, with the rapid development of social economy and the continuous improvement of agricultural technology, the problem of food shortage has been alleviated. However, in 2009, 1.02 billion people in the world were still malnourished, and The world population will continue to grow in the coming decades and is expected to reach 9 billion by the middle of this century. In order to meet the ever-expanding food demand due to rapid population growth, the world's total grain production needs to increase by 70% by 2050, and China's total grain production needs to increase by 35% by 2033. As one of the important food crops, rice accounts for 21% o...
