Rice seed cold-resistant germination-promoting seedling-strengthening agent and use method thereof

Abstract

The invention relates to a rice seed cold-resistant germination-promoting seedling-strengthening agent and a use method thereof, and belongs to the technical field of crop cultivation, quick lime (with the content >= 95%), a Bacillus subtilis commodity strain (10 billion live Bacillus bacteria / gWP), plant ash powder and ginkgo leaf or ginkgo fruit peel extract are mixed according to the mass ratio of 80-150:1.0-2.5:100-200:5-15, clean water is added to completely dissolve the mixture into a 1%-3% water solution, rice seeds are soaked in the water solution for 45-60 minutes for accelerating germination in accordance with the seed-soaking germination-accelerating technology in the prior art; when in seeding, the 1%-3% water solution is prepared according to the mass ratio, the 1%-3% water solution is uniformly poured onto the surface of pieces of a water cultivation seedling field or a seedbed of dry land seedling cultivation, or uniformly applied and mixed into seedling throwing plate nutrient soil, or applied to the surface of pieces of a direct sowing paddy field, and then seeding is performed. The rice seed cold-resistant germination-promoting seedling-strengthening agent can effectively solve the problems that rice seeds are slow to sprout and germinate, and not irregular to germinate, seedlings are weak, seedlings are susceptible to diseases, and the like, and can improve germination rate, seedling-forming rate and seedling rate of the rice seeds and strong seedling rate.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of rice cultivation, and specifically relates to the preparation and use method of a rice seed anti-cold germination-promoting and seedling-strengthening agent used under the existing rice seed soaking, germination-accelerating and seedling-raising technology and seedling-raising facilities in my country, in particular to It is a kind of rice seed soaking and germination acceleration, which can promote seed germination and germination in the process of field seedling cultivation, improve the seedling rate of rice seeds, cultivate strong seedlings, and reduce the diseased plant rate of rice seedlings in rice seedling seedlings. Preparation of the drug and its method of application. [0003] Background technique: [0004] Rice is currently the most important food crop in my country's agricultural production, and it has an important impact on our economic and social development and national food security. ...

AI Technical Summary

Problems solved by technology

During the seedling cultivation period, the atmospheric environment and the water temperature and mud temperature of the seedling cultivation site are low, and the light in the greenhouse is poor. In such an environment with low temperature and little light, it often leads to difficult germination, slow emergence, irregular seedling emergence, weak seedlings, and susceptibility at the seedling stage. disease, the emergence rate, seedling rate and strong seedling rate are low, which affects the improvement of seedling quality and the normal growth and development of rice plants after transplanting

[0005] At present, the anti-cold agent technology commonly used in production has poor effects, cannot effectively prevent the occurrence and damage of seedling diseases, and cannot improve its own material transformation and utilization during the germination process, and enhance its own stress resistance. The ability to resist unfavorable environments, and then improve its germination rate, seedling rate, strong seedling rate and stress resistance
