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

Embodiment

[0043] The granules used in this embodiment are composed of sodium benzoate 0.1%, imidacloprid 5%, metalaxyl, carbendazim, prochloraz mixture 5%, calcium peroxide 5%, indole acetic acid, paclobutrazol, gibberellin mixture 0.2% , zinc fertilizer (zinc oxide), manganese fertilizer (manganese sulfate), boron fertilizer (borax), copper fertilizer (copper sulfate) mixture 8%, carbofuran 2%, phosphate rock powder 20%, nano-microspheres of chitosan oligosaccharide 2%, sulfur 3%, attapulgite 49.7%, prepared according to the production process; the values ​​in the parentheses of the above components are mass percentages.

[0044] When the rice is directly broadcasted mechanically, the seeds in the seed tube are precisely sown through the seeding tube, and 3-5 grains are sown on demand, with a distribution diameter of 2 cm. The granules of the present invention are discharged through the discharging tube and dispersed around the seeds at a distance of 0.5 cm from the seeds.

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 ...
