Abstract

The invention provides a microcolloid particle fertilizer and its application, which is characterized in that the dispersion liquid is sprayed onto the surface of the completely suspended fine chemical fertilizer raw material particles, sprayed and dried rapidly, and the fertilizer particles with different nutrients coated by the colloid are mixed according to the needs to obtain A microcolloid particle fertilizer. After the fertilizer is dispersed in water, it forms a dispersion liquid rather than a completely dissolved solution. Even if the fertilizer is slightly soluble or insoluble, the fine particles presented after coating are uniformly dispersed in water. Further, as a water-soluble fertilizer, the micromicelle fertilizer can be used as a water-soluble fertilizer for drip irrigation, sprinkler irrigation, flushing fertilization, foliage fertilizer or high-concentration liquid fertilizer, which can replace the existing water-soluble fertilizer, and form a colloidal dispersion after being dissolved in water. The mulched fertilizer particles are transportable in the soil, increasing the uptake of nutrients by plants. It belongs to a new generation of water-soluble fertilizer integrating water and fertilizer.

Description

technical field [0001] The invention relates to the field of water-soluble fertilizers, in particular to a microcolloid particle fertilizer, and further relates to the application of the microcolloid particle fertilizer to drip irrigation and fertilization or the preparation of high-concentration liquid fertilizers to replace existing water-soluble fertilizers. Background technique [0002] Water and fertilizer integration technology can promote the rational allocation of cultivated land resources and the adjustment of planting industry structure, ensure food security, improve agricultural efficiency, and at the same time avoid the blindness and irrationality of farmers' water use, fertilizer use and production management, and reduce farmers' production burden. The realization of modern agriculture is of great significance and has broad application prospects. The fertilization method of water-soluble fertilizer is to apply the fertilizer soluble in water directly to the root...
