Problems solved by technology

In terms of properties, biogas slurry can be directly applied to the field by means of flushing, drip irrigation, sprinkler irrigation, furrow irrigation, etc., but the nutrient composition often cannot meet the growth needs of crops, and some concentrated biogas slurry needs to remove heavy metals to ensure the safe use of crops. , it is also necessary to synthesize the required nutrients and improve the storage function of the commodity
However, the direct use of biogas slurry as fertilizer not only has problems such as large dosage and poor fertilizer efficiency, but also breeds harmful bacteria, affects crop growth, and even pollutes the agricultural production environment

Abstract

The invention discloses composite microbial fluid fertilizer. The composite microbial fluid fertilizer is prepared by using biogas fluid obtained by carrying out anaerobic fermentation on hen manures of laying hens as a main raw material, compounding urea, potassium dihydrogen phosphate and microbial flora, and then mixing, dissolving, filtering, weighing and packing; the microbial flora is prepared from bacillus subtilis microbial agent and trichoderma aureoviride; the composite microbial fluid fertilizer is mainly prepared from the following raw materials in percentage by weight: 89.3 to 91.8 percent of biogas fluid obtained by carrying out anaerobic fermentation on the hen manures of the laying hens, 4 to 5 percent of the urea, 4 to 5 percent of potassium dihydrogen phosphate, 0.3 to 0.4 percent of the bacillus subtilis microbial agent and 0.2 to 0.3 percent of the trichoderma aureoviride. The invention also provides a preparation method of the composite microbial fluid fertilizer. The composite microbial fluid fertilizer disclosed by the invention is higher in fertilizer efficiency and security; the activity of soil microorganism can be quickly improved, heavy metal is degraded, soil-borne diseases are inhibited, and an indelible effect on development of crop roots and prevention and control of plant diseases and insect pests is achieved; moreover, the composite microbial fluid fertilizer can be widely applied to water and fertilizer integrated planting on crops such as a variety of grain crops, economic crops, and fruits and vegetables, and also can be used as spraying and water-jetting fertilizer applied to foliage.

Description

Technical field: [0001] The invention belongs to the technical field of liquid fertilizer production, in particular to a compound microbial liquid fertilizer and a preparation method thereof. Background technique: [0002] Biogas slurry is the residue produced by anaerobic fermentation of organic waste such as livestock and poultry manure and crop straw in a biogas digester. It is a high-quality organic compound with both quick and slow effects. Biogas slurry contains nitrogen, phosphorus, potassium, magnesium, calcium and other elements needed by plants, as well as a large number of active organic components, such as humic acid, indole acetic acid, lactic acid bacteria, gibberellin, cytokinin and other plant hormones, B vitamins, amino acids, proteins, hydrolytic enzymes, various inorganic acids and some antibiotics, etc., these components coordinate with each other in the form of quick-acting nutrients and biopesticides in the biogas slurry, which can be directly and rapid...
