[0034] Preparation of Preliminary Example 2 Aspergillus Niger Solid Inoculum

[0035] 1. Inoculate the Aspergillus niger species in the culture medium (the medium is prepared according to the formula provided by the supplier), store the culture medium slant seed strain in a refrigerator at 4°C, take it out and activate it twice before use, and transfer the activated strain to 250 ml eggplant bottle nutrient agar culture, culture temperature is 28 ℃, 48 hours when the growth is good, wash it with sterilized water, and use it as the inoculum of the seed tank;

[0036] 2. Add culture medium to a 1 ton fermenter, the composition of which is: 50% bran, 49% rice bran, 0.5% each of ammonium sulfate and potassium dihydrogen phosphate; the initial pH is 7.5; the ratio of feed to water before inoculation is 1 : 0.6. Inoculate the production tank from the seed tank to start fermentation. Fermentation conditions: culture temperature is 28°C, ventilation rate is 1:1.1, tank pressure is 0...

Abstract

The invention discloses microbial straw decomposition additive, which belongs to the field of straw decomposition additive and is obtained through combining four bacteria: bacillus subtilis, aspergillus niger, trichoderma reesei and saccharomyces cerevisiae. The microbial straw decomposition additive utilizes the temperature rise benefit of the aspergillus niger spore enzyme activity for raising the environment temperature of decomposition, the further temperature rise benefit in the growth process of the bacillus subtilis is cooperated, and the temperature required by the decomposition is ensured, so the decomposition effect of straws is improved. The microbial straw decomposition additive has the obvious temperature rise benefit and can be used for the in-site field returning decomposition of the straws, the straw decomposition can be better accelerated in low-temperature and normal-temperature environment, the bottleneck problem of straw utilization is solved, the straw burning can be effectively reduced, the decomposition work procedure and the labor cost are saved, the fertilizer feeding is reduced, the soil structure is improved, and the planting benefit is improved.

Description

technical field [0001] The invention relates to a straw decomposing agent, in particular to a microbial decomposing agent for rapidly decomposing straw, and also relates to a preparation method and application of the microbial decomposing agent, belonging to the field of straw decomposing agents. Background technique [0002] Studies have shown that China's increasingly serious problems of cultivated land soil compaction and soil fertility decline are caused by the low content of soil organic matter and the application of large amounts of chemical fertilizers and less use of organic fertilizers. The method of returning straw to the field can effectively increase the content of soil organic matter, thereby improving the physical and chemical properties of the soil, but the direct returning and burning of excess straw has caused agricultural safety and environmental problems. Therefore, the development of biological straw decomposing agent for straw returning Tian has very imp...
