A kind of growth regulator for promoting the root growth of regenerated rice and its application method

Abstract

The invention discloses a growth regulator for promoting growth of the root of regeneration rice and an application method thereof. The plant hormones of the growth regulator are prepared from 2,4-epibrassinolide, gibberellin and 3-heteroauxin. The regulator can effectively promote generation of new root of the regeneration rice and growth of the root, the yield of the regeneration rice can be increased by 17%, the effect of the growth regulator is outstandingly better than independent application or mixing application of two of 2,4-epibrassinolide, gibberellin and 3-heteroauxin.

Description

technical field [0001] The invention relates to the field of plant growth regulators, in particular to a growth regulator for promoting root growth of regenerated rice and an application method thereof. Background technique [0002] The contradiction between population increase, arable land decrease, and lack of water resources has led to a very severe food security situation in my country. Rice production is closely related to my country's food security. However, rapid urbanization has led to the loss of agricultural labor, and the increase in production costs has led to a decline in economic benefits. At present, rice production is facing serious problems of lack of people and no one willing to farm. Under the new situation, it is necessary to solve the problem of increasing the yield and efficiency of rice production, among which, ratooning rice has become one of the most effective production methods. [0003] In recent years, researches on variety selection and scientif...

AI Technical Summary

Problems solved by technology

[0005] At present, the types of root-growth-stimulating regulators on the market are relatively single, and the effects of applying different root-growth-stimulating hormones to different plants are also different, and there are relatively few studies on compound root-growth-stimulating regulators. In addition, plant There is a complex relationship between growth hormones. How to compound growth hormones to produce synergistic effects and further improve the effect of growth hormones in crops, because of its ratio, selection and combination of types and effects on different plants There are still huge technical difficulties in different parts
