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
Even for the fermentation of organic fertilizers, due to the raw materials of organic fertilizer fermentation, such as animal manure and plant fibrous waste, due to different sources and different batches, the carbon and nitrogen content, pH value, inorganic salts, trace elements, etc. are all different. There are certain differences. The combination of a small number of strains cannot well adapt to the differences in raw materials in actual production, and cannot exert stable fermentation capacity for variable batches of raw materials. The use of such microbial agents with insufficient microbial compounding ability leads

Embodiment 1

[0047] The production of embodiment 1 microbial bacterial agent

[0048] 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 soil conditioners

[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 tempera...

Embodiment 3

[0055] The effect of embodiment 3 soil conditioner application

[0056]The soil improver produced by the same method as in Example 2 has been applied to the main grain producing areas of my country's Heilongjiang since 2004 to plant rice, wherein 100-150kg is applied 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. At the same time, we commissioned the National Grain Bureau Scientific Research Institute to detect that compared with the...

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation. Specifically, the present invention relates to a soil conditioner used for fermenting and producing organic fertilizers. The stability and adaptability of the fermentation are good, and the soil conditioner produced by fermentation can improve soil fertility, It has excellent performance in reducing the content of harmful elements, eliminating pesticide residues, or improving saline-alkali land. In addition, the present invention also relates to a soil conditioner produced by fermentation of the above-mentioned microbial agent and its application. 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, the residues of chemical fertilizers in agricultu...
