Multifunctional compound fertilizer

Abstract

The invention discloses a multifunctional compound fertilizer which is prepared from the raw materials including urea, ammonium sulfate, monoammonium phosphate, potassium chloride, silico-calcium fertilizer, ammonium lignosulphonate, amino acid, fermented rape seed cake, zinc sulfate, magnesium sulfate, borax, kieselguhr, magnesia, ammonium molybdate and polyaspartic acid through crushing, mixing and pelletizing. The multifunctional compound fertilizer contains not less than 35 percent of total nutrients of nitrogen, phosphorus and potassium, not less than 15 percent of organic matters, not less than 6 percent of amino acid, not less than 5 percent of humic acid, not less than 6 percent of trace elements and not less than 0.15 percent of synergist. The multifunctional compound fertilizer has functions of resisting insects and diseases, controlling loss, increasing effect and efficiency, maintaining land, and protecting environment.

Description

technical field [0001] The invention relates to crop fertilizers, in particular to a multifunctional compound fertilizer. Background technique [0002] At present, the compound fertilizers produced in China are mainly composed of chemical fertilizers such as nitrogen, phosphorus, and potassium. The spread of soil-borne diseases such as shin disease, the intensification of insect pests, the overgrowth of weeds, the increase in the use of pesticides year by year, and the serious environmental pollution have restricted the sustainable development of China's modern agricultural industry. Therefore, organic-inorganic compound fertilizers produced from livestock and poultry manure have attracted attention , but although the fertilizer contains organic matter, the nutrient content is low, it cannot meet the needs of crop growth for nutrients, and the effect is not significant. In addition, the content of harmful substances such as antibiotics and heavy metals in livestock and poult...

Problems solved by technology

[0002] At present, the compound fertilizers produced in my country are mainly composed of chemical fertilizers such as nitrogen, phosphorus, and potassium. The spread of soil-borne diseases such as shin disease, the intensification of insect pests, the overgrowth of weeds, the increase in the use of pesticides year by year, and the serious environmental pollution have restricted the sustainable development of my country's modern agricultural industry. Therefore, organic-inorganic compound fertilizers produced from livestock and poultry manure have attracted attention , but although the fertilizer contains organic matter, the nutrient content is low, it cannot meet the needs of crop growth for nutrients, and the effect is not significant. In addition, the content of harmful substances such as antibiotics and heavy metals in livestock and poultry manure is high, which cannot guarantee the safety of agricultural products; and the above two Fertilizers have the defects of incomplete nutrition and single function
