Powder organic-inorganic water-soluble fertilizer and preparing method thereof

Abstract

The invention belongs to the field of soil fertilizer, and discloses a powder organic-inorganic water-soluble fertilizer and a preparing method thereof. The powder organic-inorganic water-soluble fertilizer comprises water-soluble organic matter, microelement water-soluble fertilizer, medium element water-soluble fertilizer, and a water-soluble anti-blocking agent. The content of nitrogen, phosphorous and potassium is larger than or equal to 30%, the content of calcium and magnesium is larger than 1%, and the content of organic matter is larger than 10%. According to the powder organic-inorganic water-soluble fertilizer and the preparing method thereof, the preparing technology is simple, the condition is mild, heating and fermenting are not needed, particles do not need to be prepared into, the four materials are directly uniformly mixed to prepare the powder organic-inorganic water-soluble fertilizer, the powder organic-inorganic water-soluble fertilizer can promote the absorption and utilization of crop to nitrogen, potassium, calcium and magnesium, soil beneficial microorganism reproduction is promoted, soil acidization and salinization are relieved, the crop root system growth is promoted, the utilization efficiency of crops to the water and nutrients is improved, the capability of the crops in resisting adversity is improved, and finally the purposes of increasing the yield and improving the product quality are achieved. Long term application of the powder organic-inorganic water-soluble fertilizer can also improve the soil structure and raise land fertility.

Description

technical field [0001] The invention belongs to the field of soil fertilizers, in particular to a powder organic and inorganic water-soluble fertilizer and a preparation method thereof. Background technique [0002] Since the reform and opening up, the outstanding contribution of nitrogen, phosphorus and potassium fertilizers to crop yield has led to the rapid promotion of the application of nitrogen, phosphorus and potassium fertilizers, and the amount of application has been rising steadily. With people's endless pursuit of high crop yields, the input of chemical fertilizers is obviously high. In order to save labor costs, farmers use a large amount of chemical fertilizers for irrigation. Due to the high cost of manual application of organic fertilizers, it is difficult to find good organic fertilizer sources The fertilizer utilization rate of ordinary organic fertilizers is low in the current season, and the enthusiasm of farmers to apply organic fertilizers is getting lo...

AI Technical Summary

Problems solved by technology

[0004] Solid organic and inorganic fertilizers are not affected by solubility, have high content, and low packaging and transportation costs. However, the current invention patents for solid organic and inorganic fertilizers are mostly granules, and the preparation process is complicated. Granular fertilizers are more suitable for soil base application and topdressing. Fertilizer efficiency is slow. If irrigation facilities are used together with water, there will be a problem of slow dissolution, and the advantages of water and fertilizer integration cannot be fully utilized.
