Rice seed soaking agent and preparation method and application thereof

Abstract

The invention discloses a rice seed soaking agent and a preparation method and application thereof. The rice seed soaking agent is prepared from, by weight, 0.001-1% of a brassinolide compound, 1-5% of calcium saccharine, 0.01-5% of vitamin E nicotinate, 0.5-10% of dipotassium glycyrrhizinate, 0.025-2.5% of polyglutamic acid, 0.025-2.5% of sodium diacetate and the balance solvents. The rice seed soaking agent can greatly promote the growth of rice root systems, enhance the quality of rice seedlings, remarkably improve the germination activity of rice seeds, promote the rapid rooting germination of rice, increase the yield of the rice and improve the quality of the rice, and is easy to degrade without residue; in addition, the photosynthetic efficiency of the rice can be promoted, photosynthesis and plant tissue differentiation can be promoted, cold resistance of plants can be improved, the water retention capability of the plants can be improved, cell membrane permeability can be reduced, and resistance can be enhanced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice seed soaking agent and its preparation method and application. Background technique [0002] Rice direct seeding technology is popular among farmers for its advantages of reducing labor intensity and saving production costs. According to incomplete statistics, the area of ​​direct-directed rice in my country has exceeded 2 million ha (hectares) at present. According to the law of the development of foreign rice cultivation technology with industrialization and marketization, direct seeding will be an important direction of rice cultivation in my country in the future. In developed countries such as Europe, America and Australia, since the 1970s, driven by industrialization and urbanization, almost all rice planting adopts direct seeding. At present, the area of ​​direct-directed rice in my country is also increasing year by year. It can be predicted that with the ...

AI Technical Summary

Problems solved by technology

Adjust the physiological and biochemical functions of seeds through chemical control technology, and promote the rapid rooting and germination of rice seeds, which is used to solve the problem of increased soil carbon-nitrogen ratio in the prior art, microorganisms and rice seedlings competing for nitrogen, and insufficient nitrogen supply capacity for rice seed germination; at the same time, the soil is too loose , there are many large pores, the seeds cannot be in close contact with the soil, which will affect the germination and growth, the roots will not be firm, yellow seedlings, dead seedlings, and yield reduction will appear.
