Abstract

The invention provides a micro colloid particle fertilizer and application thereof. The micro colloid particle fertilizer is characterized by being prepared through the following steps: spraying a dispersion liquid to the surface of completely suspended micro chemical fertilizer raw material particles, quickly performing spray-drying, and finally blending colloid-coated fertilizer particles different in nutrients according to the needs. The fertilizer is dispersed in water to form a dispersion rather than a non-completely dissolved solution; even the micro particles of a slight soluble or insoluble chemical fertilizer after being coated can be evenly dispersed in water. Furthermore, the micro colloid particle fertilizer, as a water-soluble fertilizer, is applied to a drop irrigation fertilizer, a spray irrigation fertilizer, a flushing fertilizer and a leaf fertilizer, or applied to preparing a high-concentration liquid fertilizer; the micro colloid particle fertilizer is capable of taking the place of the existing water-soluble fertilizers and dissolved in water to form a colloid dispersion; the colloid-coated chemical fertilizer particles are transportable in soil so that the absorbing ability of plants to nutrients can be enhanced. The micro colloid particle fertilizer belongs to a new generation water-fertilizer integrated water-soluble 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...
