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 the grain filling plumpness of rice, and a preparation method and a use method thereof, and belongs to the technical field of plant growth regulators. The chemical regulator is prepared by mainly compounding salicylic acid, vitamin C, zinc sulfate, potassium dihydrogen phosphate, boric acid and an emulsifier, can improve the thousand seed weight of rice grains, increase the initial power of grain filling, the maximum filling rate and the average filling rate and shorten the time required by reaching of the maximum filing rate to improve the polished rice rate and the entire polished rice rate of grains and reduce the unsound grain rate and the chalky grain rate of the grains, and has a substantial regulation effect on rice weak power grains. The regulator has the advantages of easily available raw materials, low cost and no toxic side effects. The use method is simple and is easy to realize. The preparation method of the chemical regulator for improving the grain filling plumpness of rice has the advantages of simple process, simple operation, and easy industrial popularization 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...
