Problems solved by technology

Although the above-mentioned patent can improve the safety of rice seedlings to pretilachlor, but for the control of weedy rice, it also improves the resistance of weedy rice to pretilachlor, which greatly reduces the control effect
There is no direct-seeding rice seed soaking agent that can specifically improve the safety of rice seedlings to pretilachlor

Abstract

The invention discloses a paddy rice seed soaking agent and application thereof. The paddy rice seed soaking agent mainly comprises a safener and a plant growth regulator, wherein the safener is femclorim; and the plant growth regulator is one or more of indolebutyric acid, naphthylacetic acid and brassinolide. Moreover, other aids such as a carboxylate dispersing agent, a polyether-modified high molecular wetting agent, xanthan gum, an antifreezing agent, a defoaming agent and the like. The paddy rice seed soaking agent has high safety, and is suitable for seed soaking of manual direct seeding, mechanical direct seeding, direct seeding on dry paddy fields and direct sowing in flooded paddy fields; by adopting the paddy rice seed soaking agent, the pesticide damage of pretilachlor to paddy rice can be reduced remarkably, the growth of rice roots can be facilitated simultaneously, and the quality of paddy rice seedlings is enhanced; and meanwhile, compared with spraying after seeding of paddy rice, the seed soaking agent has the advantages of small using amount and low cost.

Description

technical field [0001] The invention relates to a rice seed soaking agent specially used for direct-seeding paddy fields and an application thereof. 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). According to the law of the development of foreign rice cultivation technology with industrialization and marketization, adopting direct seeding is one of the important directions 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 improvement of the sca...
