A kind of rice machine direct-seeding growth-promoting granule and its preparation method and application

Abstract

The invention relates to the technical field of rice planting, in particular to a rice machine-directed growth-promoting granule and its preparation method and application, which consist of preservatives, insecticides, fungicides, oxygen enhancers, plant growth regulators, trace elements , rodent repelling agent, filler, nano microsphere of natural polysaccharide, coating agent and binder. Active ingredients such as pesticides and fertilizers in the granules of the present invention are separated from the seeds to avoid direct contact with the inhibitory and toxic effects on seed germination and seedling tissue growth. For large areas of rotten seeds and lack of seedlings caused by seed rot and fermentation, the emergence rate of rice mechanical direct seeding can be increased by 18.33%-26.83%, and the seedling rate can be increased by 63.07%-109.51%.

Description

Technical field[0001]The present invention relates to the field of rice planting, and in particular, a live granule and preparation method thereof of rice machine and its preparation method thereof.Background technique[0002]At present, with the development of rice cultivation technology, the improvement of rural economy, the change of labor structure, the increase in agricultural mechanization, and the growth of agricultural investment costs, and rice live is lightly simplified, and the characteristics of the provinces are deeply affected by my country. Welcome to workers. Especially because live rice is more likely to achieve mechanization, it can save a lot of labor in large-area rice planting, to mitigate the contradiction between labor season, and have an important significance for realizing the lightweight, specialization, and scale of rice production, with broad Application prospects. Therefore, rice mechanized live broadcast has become one of the important directions of rice ...

AI Technical Summary

Problems solved by technology

[0005] (1) The coating thickness of seed dressing coating powder and coated seeds is difficult to ensure consistency, resulting in different sizes of coated seeds, thus failing to meet the requirements of mechanical direct seeding precision sowing

[0006] (2) Coated seeds are easy to absorb moisture, which is not convenient for long-term storage of seeds

[0008] (4) Oxygenating agent components commonly used in seed coating agents such as calcium peroxide produce a large amount of alkaline components at the same time as oxygen is released, because of direct contact with germinated seeds, resulting in dehydration or "salt damage" of seedlings, resulting in the emergence of direct-seeding rice rate drop

However, the coating components of the current method need to be directly attached to the seeds, so all or part of the above-mentioned shortcomings cannot be avoided.
