Rape seed pelleting fertilizer

Abstract

The invention relates to a rape seed pelleting fertilizer which is prepared by grinding and refining macroelement fertilizer of NPK, microelement fertilizer of boron, active ingredients of plant growth regulator heteroauxin and the like, with inactive ingredients of film-forming agent hydroxyl propyl cellulose, auxiliaries and the like. The invention is of a novel fertilizer which is used for pelleting rape seeds, and coating the fertilizer on the surfaces of the rape seeds. According to the invention, the mass ratio of fertilizer to seeds is 1:30-1:60, a pelleting film with a microfine film pore channel is formed on the surfaces of the seeds in pelleting, the fertilizer nutrients are slowly released by the pore channel, and the duration period lasts for 60 to 73 days. The rape seed pelleting fertilizer is suitable for pelleting various rape seeds, conducts direct seeding or seedling growing, and can prompt the growth of rape, enhance stress resistance, improve the percentage of seedling emergency by 9.6 percent to 15.2 percent, save fertilizer by 20.8 percent to 28.1 percent, and save seeds by 8.7 percent to 14.0 percent. The rape seed pelleting fertilizer is simple and convenient to produce, low in cost, and convenient to use, and has obvious economic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention relates to a preparation for coating rapeseeds and wrapping fertilizers on the surface of seeds, and belongs to the fields of novel fertilizer preparation technology and rapeseed cultivation technology. Specifically, it is a rapeseed coating fertilizer, which is a rapeseed coating fertilizer obtained by grinding and refining macroelement fertilizers, trace element fertilizers, plant growth regulators, film-forming agents, colorants and auxiliary agents. Background technique [0002] Since German chemist Liebig J V first proposed the theory of plant mineral nutrition in 1840, fertilizers have become a powerful force to promote the development of global agricultural production. However, after more than 100 years of development, the release rate of fertilizer nutrients has been uncontrollable. The release rate is too fast, and the crops will lose it before they can absorb it, resulting in a low fertilizer utilization rate, generally only 30%...

AI Technical Summary

Problems solved by technology

[0005] (2) The coating materials of the existing slow / controlled release fertilizers are expensive, the equipment investment is large, the production process is complicated, the coating process requires long-term high temperature (80-170°C) treatment, and the energy consumption is large, resulting in slow / controlled release fertilizers The production cost is high, and its price is 5 to 14 times that of ordinary fertilizers before coating

[0006] (3) Existing slow / controlled release fertilizers use petroleum solvents such as toluene, xylene, and petroleum ether to dissolve coating materials, which are highly toxic and harmful to the health of production and application personnel; some use trichloroethylene, tetrachloroethylene, etc. As a solvent, it will destroy the ozone layer and cause air pollution

[0007] Due to the above reasons, the application range of existing slow / controlled release fertilizers is very limited, mainly used for high-value economic crops such as flowers, lawns, fruits, and tobacco, and rarely used for field crops such as cotton, rapeseed, and rice
