Growth-promoting granule for mechanical direct sowing of rice and preparation method and application thereof

Abstract

The invention relates to the technical field of rice planting, and particularly relates to a growth-promoting granule for mechanical direct sowing of rice and a preparation method and application thereof. The growth-promoting granule is prepared from a preservative, an insecticide, a bactericide, an oxygen producer, a plant growth regulator, microelements, a mice and sparrow repellent, a filler, natural polysaccharide nanospheres, a film agent and a binder. The effective ingredients, such as a pesticide and a fertilizer, in the granule are separated from seeds, and inhibition and poisoning effects of direct contact on seed germination and seedling tissue growth are avoided. The preservative is added to the granule, so that large-area seed decay and seedling missing caused by seed decay and fermentation in high-humidity and flooding environments can be effectively prevented, the emergence rate of mechanical direct sowing of the rice can be improved by 18.33-26.83%, and the seedling rate can be improved by 63.07-109.51%.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a rice machine-directed growth-promoting granule and a preparation method and application thereof. Background technique [0002] At present, with the development of rice cultivation technology, the improvement of rural economy, the change of labor force structure, the improvement of agricultural mechanization and the increase of agricultural input cost, rice direct seeding is favored by my country's agricultural industry because of its lightness, simplification, cost saving and labor saving. Workers welcome. In particular, since direct-directed rice is easier to mechanize, it can save a lot of labor when used for large-scale rice planting, and alleviate the contradiction of labor seasonal tension. application prospects. Therefore, mechanized direct seeding of rice has become one of the important directions of rice cultivation in my country. [0003] In view of the silted ...

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.
