Amino-peptide-zinc-potassium compound fertilizer and preparation process thereof

Abstract

The present invention discloses anamino-peptide-zinc-potassium compound fertilizer and a preparation process thereof. The compound fertilizer is prepared from the following raw materials in parts by weight: 100-200 parts of nitrogenous fertilizer, 100-200 parts of phosphorous fertilizer, 100-200 parts of potash fertilizer, 100-200 parts of water-soluble phosphorous fertilizer, 50-100 parts of potassium chloride, 1-2 parts of polymerized polypeptide, 1-2 parts of polypeptide zinc, 1-2 parts of natural nano mineral crystal bars and 0.5-1 part of chelated trace elements. Various natural nano mineral rod crystals, active polypeptide and chelated trace elements are used as raw materials and then are physically and biologically modified and are mixed with a compound material to be processed intoa powder product; therefore, the prepared fertilizer specifically has the functions of improving soil and controlling nutrient loss of the fertilizer; the polymerized fertilizer formed by connectingpeptide bonds has the effects of chelating fertilizer nutrients, providing organic nitrogen nutrients and promoting growth and development of crops.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an aminopeptide zinc-potassium compound fertilizer and a preparation process thereof. Background technique [0002] The rapid development of agriculture has greatly increased the use of chemical fertilizers, but the excessive use of chemical fertilizers has resulted in a decline in agricultural soil quality, a decrease in the yield and quality of agricultural products, and a certain degree of damage to the ecological environment. Taking nitrogen fertilizers as an example: my country uses about 21 million pure nitrogen per year The nitrogen fertilizer loses an average of 45% through volatilization, leaching and runoff. The annual loss of nitrogen is as high as 9.45 million tons, which is equivalent to more than 20.5 million tons of urea. It also caused a series of environmental problems. Therefore, how to improve the utilization rate of fertilizers and give full p...
