Embodiment 1

[0025] A liquid with a solid content of less than 1% is obtained by anaerobic fermentation of cow dung as raw material to produce biogas, and is used for standby; low-rank coal is selected from Inner Mongolia lignite,

[0026] Bacillus strains were inoculated into the seed tank Fu for 12 hours according to the conventional method, and then inoculated into the fermentation tank for 24 hours to obtain the bacterial liquid obtained after fermentation, and the bacterial concentration was 1×10 8 cfu / mL, spare,

[0027] Mix 85kg of the above-prepared biogas slurry and 10kg of -60mesh Inner Mongolia lignite into the fermentation tank, and at the same time add 7kg of the above-prepared Bacillus culture solution and mix them for 20 days at a temperature of 25-28°C to obtain The biogas slurry organic nutrient solution, the pH of the product is stable at 7.5-7.8 for more than 2 months, the total N reaches 2800mg / kg, and the soluble P reaches 138.6mg / kg.

Embodiment 2

[0029] A liquid with a solid content of less than 1% is obtained by anaerobic fermentation of pig manure to produce biogas, and is used for standby; the low-rank coal is selected from Xinjiang weathered coal,

[0030] Bacillus strains were inoculated into seed tanks and cultivated for 18 hours according to conventional methods, and then inoculated into fermentors to ferment for 18 hours. 8 The bacillus culture solution of cfu / mL, standby,

[0031] Mix 80kg of the above-prepared biogas slurry and 18kg of -80 mesh Xinjiang weathered coal into the fermentation tank, and at the same time add 8kg of the above-prepared Bacillus culture solution and mix them to ferment for 20 days at a temperature of 25-28°C to obtain a stable Biogas slurry organic nutrient solution with high performance, the product pH is 8.7-8.9, the total N reaches 3100mg / kg, and the soluble P reaches 154mg / kg.

Embodiment 3

[0033] A liquid with a solid content of less than 1% is obtained by anaerobic fermentation of mixed manure from cow dung and pig manure to produce biogas, and it is used for standby; coal gangue is used for low-rank coal.

[0034] Bacillus strains were inoculated into seed tanks and cultivated for 24 hours according to conventional methods, and then inoculated into fermentors to ferment for 12 hours to obtain the bacterial liquid with a concentration of 1.2×10 8 The bacillus culture solution of cfu / mL, standby,

Abstract

The invention relates to an organic biogas slurry nutrient solution with stable property and a production method thereof. The production method is characterized by comprising the steps of: selecting biogas slurry, low-rank coal or humic acid, straws and a bacillus culture solution as raw materials, mixing 70-85 parts of biogas slurry, 10-20 parts of low-rank coal or humic acid and 0-5 parts of straws and adding into a fermenting tank, inoculating 5-10 parts of bacillus culture solution and mixing uniformly, and fermenting at a temperature of 25-28 DEG C to obtain the organic biogas slurry nutrient solution. The organic biogas slurry nutrient solution is a complete organic matter and an environmental-friendly product without secondary pollution, has the advantages of rich nutrient substances, stable property and simple process, can be used as a growth regulating agent for promoting the development of a plant root system, and has the effects of stimulating the growth of the plant, promoting the photosynthesis, storing nutrition constituents, and being stored for a long time and transported in a long distance.

Description

technical field [0001] The invention relates to a biogas slurry organic nutrient solution with stable performance, belonging to the technical field of agricultural fertilizers. [0002] The invention also relates to a production method of the biogas slurry organic nutrient solution. Background technique [0003] Biogas fermentation is one of the important ways to effectively utilize biomass resources, including livestock and poultry manure, crop straw, urban organic waste, etc., to obtain biomass energy. At present, with the development of industrialized biogas, a large amount of biogas slurry will be produced intensively, and the effective utilization and rational consumption of biogas slurry will become one of the important factors for the development of biogas industry. [0004] At present, in large-scale biogas projects, the production of biogas slurry is very large. As a nutrient solution of biogas slurry, it can be widely used in soilless substrate cultivation, hydrop...
