Special biogas residue fertilizer for rape and preparation method of fertilizer

Abstract

Special biogas residue fertilizer for rape is prepared from components in parts by mass as follows: 100 parts of rice straw, 5-15 parts of ammonium sulfate, 2-5 parts of micronutrient elements, 5-10 parts of urea, 10-20 parts of monoammonium phosphate, 10-15 parts of potassium chloride, 20-30 parts of distiller's grains, 3-5 parts of traditional Chinese medicine radix codonopsis dregs, 10-20 partsof fermented cow manure and 100-200 parts of biogas residues. Rapeseed oil produced with the special biogas residue fertilizer for rape contains little erucic acid and is beneficial to human health.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a special biogas residue fertilizer for rapeseed and a preparation method thereof. Background technique [0002] As one of the most effective ways to solve the pollution of livestock and poultry manure and crop cow manure, biogas technology has developed rapidly in recent years, and its potential environmental and economic benefits have been recognized by the society; however, the biogas technology produced after anaerobic fermentation, The further deep processing of biogas residues makes it less reported that it is directly applied to crops as a commodity. In addition, for large-scale alcohol factories, monosodium glutamate factories and other enterprises, the treatment of biogas slurry and biogas residues produced has become a difficult problem; if these biogas slurry, Disposal or improper use of biogas residues will inevitably cause waste of resources and secondary pollutio...

[0002] As one of the most effective ways to solve the pollution of livestock and poultry manure and crop cow manure, biogas technology has developed rapidly in recent years, and its potential environmental and economic benefits have been recognized by the society; however, the biogas technology produced after anaerobic fermentation, The further deep processing of biogas residues makes it less reported that it is directly applied to crops as a commodity. In addition, for large-scale alcohol factories, monosodium glutamate factories and other enterprises, the treatment of biogas slurry and biogas residues produced has become a difficult problem; if these biogas slurry, Disposal or improper use of biogas residues will inevitably cause waste of resources and secondary pollution; studies have found that biogas residues and biogas slurry contain a variety of nutrients (such as nitrogen, phosphorus, potassium, trace elements) and organic matter, crude protein, amino acids , cellulose, hemicellulose, lignin, humic acid and other organic substances, biogas slurry and residue from different sources may also contain stress-resistant substances (such as proline, linoleic acid, etc.), various hydrolytic enzymes, auxin (such as abscisic acid, gibberellin, etc.) and some antibiotics, beneficial bacteria, etc.; these substances can promote plant growth and development, improve soil, enhance crop resistance (disease and pest, drought, cold, etc.), and then improve crop The effect of yield and quality; although biogas slurry and biogas residue contain a variety of nutrients, the nutrient content is very low. If biogas residue and biogas slurry are simply applied to crops, they cannot meet the nutrient requirements of crops throughout the growth period. Combined with chemical fertilizer

[0003] Rapeseed is an annual or annual (winter crop) crop. The extracted rapeseed oil is rich in fatty acids and multivitamins, and has high nutritional value. It is the main edible oil in many areas and has a wide range of uses in industry. The erucic acid content of rapeseed oil on the market is about 6%. For normal people, erucic acid is not terrible; but for heart disease patients, it may cause myocardial fat accumulation and thickening of blood vessel walls, impairing cardiovascular function, even induce myocarditis
