Problems solved by technology

[0004] However, in production practice, especially in large-scale production, the microbial compounding ability in these prior art microbial inoculum agents is insufficient
Due to the raw materials for organic fertilizer fermentation, such as animal manure and plant fibrous waste, due to different sources and different batches, there are certain differences in their carbon and nitrogen content, pH value, inorganic salts, trace elements, etc. The combination cannot well adapt to the differences in raw materials in actual production, and cannot exert stable fermentation ability for variable batches of raw materials. The use of such microbial agents with insufficient microbial compounding ability will cause the quality of fermented organic fertilizers to be unstable, and even eventually It is necessary to add chemical fertilizer raw materials to meet the specified quality standards, which completely deviates from the original intention of organic fertilizers and is difficult to meet the needs of large-scale commercial production; It is not feasible in reality to set up inspection procedures from the source of purchase from farmers, according to the required cost, human resources and small batch inspection capabilities

Embodiment 1

[0046] The production of embodiment 1 microbial bacterial agent

[0047] In this embodiment, the following strains are used to prepare microbial agents: (1) Cellulomonas flavigena, (2) Bacillus sterothermophilus, (3) Lactobacillus casei , (4) Methanobacterium formicium, (5) Methanobacterium ruminantium, (6) Thiobacillus thiooxidans, (7) Thiobacillus ferrooxidans, (8) subtilis Bacillus subtilis, (9) Bacillus licheniformis, (10) Bacillus polymyxa, (11) Streptomyces thermophilus, (12) common high temperature actinomycetes ( Thermoactinomyces vulgaris), (13) Thermomonospora curvata (Thermonospora curvata), (14) Azotobacter vinelandii, (15) Nitrosomonas europeae, (16) Nitrobacter winogradskyi), (17) Rhizobium japonicum, (18) Rhizobium leguminosarum, (19) Aspergillus niger, (20) Aspergillus oryzae, (21) Saccharomyces cerevisiae ), (22) Penicillium notatum, (23) Humicola insolens, (24) Rhizopus oligosporus, (25) Rhizoctonia cerealis. The above strains can be cultivated according t...

Embodiment 2

[0051] The production of embodiment 2 organic fertilizers

[0052] Get water content and be 65% (weight ratio) cow dung (insufficient water content can add water) and the rice bran that the particle after pulverizing is less than 5mm mixes and pulverizes with the mass ratio of 85: 15, makes the cow dung after mixing and rice bran There is no agglomeration above 40mm.

[0053] Then, the mixture of 1 ton of above-mentioned cow dung and rice bran is mixed with the microbial inoculant produced in 2kg of Example 1, and heaped into the fermenter to form a compost heap. During the compost heap placement period, along with the fermentation process, the compost heap can naturally heat up. This fermentation heating process usually takes 2-3 days, and the compost heap can be turned 1-2 times during this period. Then, when the temperature of the compost heap rises to 65°C, turn on the turner to turn the compost heap to dissipate the heat generated by fermentation to ensure that the tempe...

Embodiment 3

[0055] The effect of embodiment 3 organic fertilizer application

[0056] The organic fertilizer produced by the same method as in Example 2 is used as base fertilizer and topdressing, since 2004, it has been applied to the main grain producing areas of my country's Heilongjiang, and rice is planted, wherein 100-150kg is used per mu. According to several years of continuous follow-up testing, it is found that the soil fertility has been continuously improved, and the quality of rice has also been continuously improved (see Table 3.1). In 2004, pesticide residues had been completely eliminated; by 2008, the content of heavy metals such as cadmium and arsenic and fluorine in soil and rice had dropped by more than 50% compared with before application, and heavy metals such as lead and mercury had also decreased significantly compared with before application. The protein content of rice is also significantly improved. Simultaneously, we entrust National Grain Bureau Scientific Re...

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation. Specifically, the invention relates to a microbial bacterial agent for fermenting and producing organic fertilizers, which has good fermentation stability and adaptability, and can significantly improve soil fertility by fermenting organic fertilizers, and It does not compete with the use of chemical fertilizers, and can greatly reduce the amount of chemical fertilizers, or even eliminate the need for chemical fertilizers. In addition, the present invention also relates to an organic fertilizer produced by fermentation of the above-mentioned microbial agent, a fermentation method, and the like. Background of the invention [0002] At present, as people pay more and more attention to health and food safety, the quality requirements of agricultural products are getting higher and higher. It is hoped that on the basis of increasing the production and income of agricultural products, t...
