Thio-silicon-powder-containing composite fertilizer active additive

Abstract

The invention discloses a thio-silicon-powder-containing composite fertilizer active additive which is prepared from the following raw materials in percentage by mass: 50-60% of weathered coal, 30-35% of thio-silicon powder, 9.8-14.9% of biological bacterial fertilizer and 0.1-0.2% of plant growth regulator. The plant growth regulator is gibberellin. The thio-silicon powder is prepared by mixing the following raw materials in percentage by mass: 70-80% of potassium sulfate, 18-29% of sodium silicate and 1-2% of composite amino acid powder. The biological bacterial fertilizer is prepared by mixing the following raw materials in percentage by mass: 99.0-99.5% of feces leavening and 0.5-1.0% of microbial strain. Under the synergic actions of all the components, the additive can achieve the obvious effects of solubilizing phosphorus and potassium, fixing nitrogen, inhibiting nitrate nitrogen denitrification, reducing the fertilizer loss, enhancing the utilization ratio of the fertilizer, promoting the plant growth, enhancing the yield and quality, improving the soil, fertilizing the soil, reducing the fertilizer application pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer additives, in particular to a compound fertilizer active additive containing sulfur-based silicon powder. Background technique [0002] In recent years, the application of organic fertilizers to cultivated land in our country has been greatly reduced or even not applied year by year, while the excessive application of chemical fertilizers has led to soil compaction and difficulties in the activities and reproduction of beneficial microorganisms in the soil, making it impossible to fully utilize the transformation of nitrogen, phosphorus, and potassium and promote the growth of crops. Root absorption function, resulting in nutrient loss. In addition, soluble silicon fertilizers have been rarely applied to cultivated land in my country for a long time, resulting in a serious decline in the vegetative growth and grain yield of some crops such as rice, and even silicon deficiency.
