Problems solved by technology

These technologies, methods, equipment and projects require a large one-time investment, require a large amount of land for construction, and the disposal efficiency of biogas sludge is difficult to meet the requirements of industrialization.
[0006] At present, the excrement, urine and a large amount of house flushing water in pig breeding, and even the entire livestock and poultry breeding industry cannot be thoroughly treated as resources and used in clean agriculture

example 1

[0037] Example 1: 50% of biogas slurry in the biogas slurry fermentation tank of Hangzhou Daguanshan Pig Breeding Co., Ltd., 2% of glucose carbon source, 0.5% of EM bacterial agent, and 47.5% of tap water; the temperature is 30°C, and the underwater stirrer is the preparation container The flow rate of the oxygenator is 150%, the flow rate of the oxygenator into the preparation container is 250% of the preparation container, and the cultivation time is 10 days to form a sol-like bacterial fertilizer, which is the final product.

example 2

[0038] Example 2: 50% of biogas sludge, 2% of brown sugar, 0.5% of EM bacterial agent, and 47.5% of river water in the biogas slurry fermentation tank of the pig farm of Hangzhou Daguanshan Pig Breeding Co., Ltd.; the temperature is 30°C, and the flow rate of the underwater stirrer is the preparation container 100%, the aeration flow rate of the oxygenator into the preparation container is 250% of the preparation container, and the cultivation time is 15 days to form a sol-like bacterial fertilizer, which is the final product.

example 3

[0039] Example 3: 45% biogas sludge, 2% rice bran, 0.5% bacillus agent, and 47.5% river water in the biogas slurry fermentation tank of the pig farm of Hangzhou Daguanshan Pig Breeding Co., Ltd.; the temperature is 30°C, and the flow rate of the underwater stirrer is the preparation container 200%, the aeration flow rate of the oxygenator into the preparation container is 250% of the preparation container, and the cultivation time is 30 days to form a sol-like bacterial fertilizer, which is the final product.

[0040] The swamp mud is the sediment after the pig farm manure is fermented in a fermenter or a fermenter. The carbon source is one or more mixtures of glucose, brown sugar, starch, rice bran and bran. The aerobic fermentation bacteria agent is bacillus, EM bacteria, rhizobia bacteria agent, nitrogen-fixing bacteria agent, phosphorus-solubilizing microbial agent, silicate microbial agent, photosynthetic bacteria agent, organic material decomposing agent, growth-promotin...

Abstract

The invention discloses a liquid bacterial fertilizer prepared from pig farm biogas mud and a preparation method and an application method thereof, and belongs to the technical field of crop ecological cultivation. The liquid bacterial fertilizer is prepared from the following substances in parts by weight: 30-70 parts of pig farm biogas mud, 0.1-5 parts of a carbon source, 0.01-1 part of an aerobic fermentation inoculant and 24-70 parts of clear water. According to the liquid bacterial fertilizer prepared from the pig farm biogas mud and the preparation method and the application method thereof, rich nutrient substances in the pig farm biogas mud are utilized, a carbon source and an aerobic bacterial agent required by microorganism breeding are added, and the liquid bacterial fertilizer is cultured under certain temperature and oxygenation conditions. In different production links of rice seed soaking, seedling raising, field growing and the like, the biogas mud bacterial liquid is utilized through the technical methods of seed soaking, spraying, flushing and the like, the germination rate of rice seeds is increased, rice seed-borne diseases are eliminated, the seedling quality is improved, bud seedling diseases are reduced, the seedling quality is improved, the occurrence of bud seedling diseases is reduced, and the paddy rice yield and the yield are improved.

Description

technical field [0001] The invention belongs to the technical field of crop ecological cultivation, in particular to a liquid bacterial manure prepared from pig farm swamp mud, a preparation method and an application method thereof. [0002] technical background [0003] Rice is an important food crop in my country, and 60% of the country's residents use rice as their ration. The management of rice planting, seedling raising, transplanting and field growth and development requires seed disinfection, seedling raising management and field planting production management. The entire production process of rice from seed to paddy rice requires a lot of nutrient and pest management in addition to production management operations. With the improvement of people's living standards, the green requirements of social housing and rural environments, and the green development of agriculture, rice cultivation increasingly needs to use less or no chemical fertilizers and pesticides.
