Organic-inorganic mixed fertilizer specially used for soybean

Abstract

The invention provides organic-inorganic mixed fertilizer specially used for soybean. The organic-inorganic mixed fertilizer specially used for the soybean is obtained by carrying out the following ten steps: preparing a fertilizer adsorbing and releasing matrix material, preparing a fertilizer retaining matrix material, preparing a fertilizer-philic matrix material, preparing root-philic organic fertilizer, mixing, testing, formulating, preparing macroelement inorganic fertilizer, compounding and mixing as well as pelletizing. The organic-inorganic mixed fertilizer specially used for the soybean has the beneficial effects that an adsorption structure in soil can be improved, and nutrient elements released from mixed fertilizer can be conveniently adsorbed and released; the nutrient elements released from the mixed fertilizer can be prevented from being lost; the fertilizer-philic matrix material and the root-philic organic material can enable the mixed fertilizer to be well contacted with and compatible with roots of the soybean, so that nutrient element absorption efficiency of the roots is improved; a nutrient structure meets need of the soybean; and by applying the organic-inorganic mixed fertilizer specially used for the soybean, fertilizer loss can be reduced, harm to the ecological environment is reduced, healthy growth of the soybean is promoted, dry matter accumulation amount is increased, soybean yield is increased, soybean quality is improved, the soybean yield is increased by 14-19%, and economic benefit is greatly increased.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a special organic-inorganic compound fertilizer for soybeans conforming to the nutritional structure and absorption characteristics of soybeans. Background technique [0002] Fertilizer occupies a very important position in modern agricultural production. With the development of modern agriculture and profitable agriculture, the amount of chemical fertilizer is increasing. However, due to some unreasonable factors in the use process, the role of fertilizer has not been effectively exerted. , resulting in unbalanced distribution of fertilizers, serious waste, decreased soil fertility, lowered fertilizer utilization rate, a large amount of fertilizers that have not been absorbed by crops after application enters the environment, pollutes the environment, destroys the ecological environment, not only destroys land resources, And it also poses a threat to human health. [0003] In order to i...

However, this patent only provides a fertilizer whose nutrient structure meets the nutritional requirements of soybean plants, and does not consider how to effectively release and preserve the fertilizer and enable the roots of soybean plants to effectively absorb the fertilizer, so that the fertilizer is In practical application, it still cannot be effectively used, and there will be nutrient loss, soil nutrient imbalance, and environmental pollution.
