Quick collapsed suspension liquid compound fertilizer and preparation method thereof

Abstract

The invention provides a suspension liquid compound fertilizer capable of rapidly disintegrating, and the suspension liquid compound fertilizer comprises a thickening agent, a dispersing agent, a disintegrating agent, fertilizer nutrients and water, wherein the fertilizer nutrients include nitrogen fertilizer, phosphate fertilizer, potash fertilizer, humic acid and trace elements. The optimization of composition of the thickening agent, the dispersing agent and the disintegrating agent, under the condition of maintaining stable physical properties of the suspension liquid compound fertilizer, the disintegrating agent allows the suspension liquid compound fertilizer to be rapidly disintegrated, and significantly quickens dissolving speed, improves the using efficiency of the suspension fertilizer, in addition, the technological problem of matched use of the trace elements, the humic acid and the fertilizer can be solved, major element and trace element nutrients and organic matters required for crop growth and development are provided, deficiency symptoms in the crop growth process can be solved, soil degradation problem caused by long-term application of chemical fertilizers can be alleviated, and the domestic blank is filled. The suspension liquid compound fertilizer has the advantages of low production cost, simple equipment and less investment, and ultimately reduces the cost of agricultural production.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a large-scale and medium-trace element fertilizer applied to crops, in particular to a rapidly disintegrating suspension liquid compound fertilizer and a preparation method and application method thereof. Background technique [0002] Liquid fertilizer is a kind of fluid water-soluble fertilizer. It is more and more accepted by people because of its uniform composition, high nutrient activity, flexible formula, simple production, convenient use, and wide source of raw materials. With the development of modern facility agriculture, water and fertilizer integration technology has begun to spread widely in my country, and the core and basic principle of this technology is to apply fertilizer after dissolving it in water. Therefore, liquid fertilizers with good water solubility will continue to be popularized with the rapid development of modern facility a...

Problems solved by technology

However, because of the high nutrient content of this liquid fertilizer, the viscosity and specific gravity of the dosage form are very large. During the process of using, when the suspended liquid fertilizer is poured into a pool or bucket for dissolution and dilution, the fertilizer will quickly sink to the bottom of the pool or bucket. , requires a lot of labor or agitator to stir, especially in the automatic sprinkler irrigation or drip irrigation fertilization system, it is easy to cause uneven fertilization, which significantly reduces the use effect of suspended liquid fertilizer
