Problems solved by technology

Even if the compound fertilizer can be dissolved and dispersed in water, it is unstable, prone to sedimentation and flocculation, and easy to block pipes, so it is not suitable for the integration of water and fertilizer
[0009] According to the above, most of the water-soluble fertilizers in my country are expensive at present, which is difficult for farmers to accept, and it is difficult to promote them in field operations, and they are only suitable for a small number of economic crops.
Although mineral fertilizers based on inorganic minerals are readily available and cheap, they are insoluble in water, or have poor stability in water, cannot be irrigated with water, and are difficult to use in modern agriculture that integrates water and fertilizer. In this way, the wider application of water-soluble fertilizers is limited

Abstract

The invention discloses a water-soluble mineral fertilizer, belongs to the field of crop fertilizers, and particularly relates to a water-soluble inorganic mineral fertilizer. The water-soluble mineral fertilizer is composed of an A component, a B component and a C component, wherein the A component is composed of potash feldspar, powdered rock phosphate, medical stones, kieselguhr, bentonite and a water-soluble hydrophilic grafting agent; the B component is composed of urea, biological nitrogen-fixing bacteria, a urease inhibitor, a nitrification inhibitor and carboxymethyl starch, and the C component is composed of polyaspartic acid, polyyvinylpyrrolidone and casein. A preparation method of the water-soluble mineral fertilizer takes an inorganic mineral powder body as a main raw material, the water-soluble hydrophilic grafting agent is utilized, and the inorganic mineral powder body is dissolved in the water to form a stability colloid. The water-soluble mineral fertilizer provided by the invention contains a large number of nitrogen phosphorus and potassium elements and also contains different medium / trace elements and rare earth elements required by the growth of a plant, a soil structure is improved, the growth of the plant is improved, the product quality of a crop is improved, a raw material is easily available, the price is low, the raw material is non-pollution, the production technology is simple, and a market prospect is wide.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, in particular to a water-soluble inorganic mineral fertilizer. Background technique [0002] my country is a large agricultural country with a large population. In order to increase food production, one of the effective means is to use fertilization. At present, fertilization in the world is mainly based on chemical fertilizers. However, due to long-term excessive or unreasonable application of chemical fertilizers, the proportion of nutrients in the soil is out of balance, resulting in soil compaction, reducing the utilization rate of fertilizers and the quality of agricultural products, and the use of chemical fertilizers Production and application will cause air and water pollution, causing great damage to the environment. [0003] At present, some new types of fertilizers have appeared on the market, mainly water-soluble fertilizers. Water-soluble fertilizers are multi-component compound fert...
