Biogas residue fermentation composite fertilizer

Abstract

The invention discloses biogas residue fermentation composite fertilizer. According to the biogas residue fermentation composite fertilizer disclosed by the invention, biogas residues, amino acid additives and oil cake additives are added as main ingredients, and vinasse, sugar and protease are added, assisted with white rot fungi, saccharomycetes groups, edible fungi, orthophosphoric acid, aspergillus and protease as well as bacillus subtilis. The sources of the components are environmentally friendly, green, low in cost and rich in nutrition; components such as organic matter, humic acid, crude protein, nitrogen, phosphorus and potassium in the biogas residues can be maintained to the maximum extent, and the composite fertilizer can be applied to multiple crops, such as vegetables and fruits or grain crops, and waste materials such as the biogas residues and hairs are fully utilized, so that the effect is more comprehensive.

Description

Technical field: [0001] The invention relates to the field of crop fertilizer preparation, in particular to a biogas residue fermentation compound fertilizer. Background technique: [0002] With the sustainable development of ecological agriculture, people's enthusiasm for the development of biogas ecological agriculture is getting higher and higher, and the use of biogas residue is gradually being developed and utilized. Biogas residue is the semi-solid matter remaining at the bottom of the biogas tank after the fermentation of biogas. It is rich in organic matter, humic acid, crude protein, nitrogen, phosphorus, potassium and various trace elements and plant auxins. [0003] Since biogas residue is rich in organic matter, aerobic composting of biogas residue to produce organic fertilizer has gradually become a major trend in biogas residue treatment. When using biogas residue to produce organic fertilizer, due to the different fermentation raw materials, such as biogas residue f...

AI Technical Summary

Problems solved by technology

When using biogas residues to produce organic fertilizers, due to the different fermentation raw materials, such as biogas residues formed by fermentation of livestock and poultry manure, biogas residues formed by fermentation of plant straw, and biogas residues formed by sludge, different fermentation materials The formed biogas residues are very different in texture, composition, etc., and they need to be treated separately when they are made into organic fertilizers. At the same time, the existing technology cannot guarantee the nutritional elements of the obtained fertilizers when using biogas residues to prepare organic fertilizers. On the other hand, the nutrient elements in the biogas residue are easy to lose during the preparation process. Two reasons lead to the poor fertilizer efficiency of the obtained organic fertilizer, and the application effect is not obvious.
