Embodiment 4

[0036] In the original seed field of Ningjin County, Hebei Province, where the highest surface temperature is lower than 5°C in the winter half of the year, the decomposition rate of the composite microbial bacterial agent in Examples 1-3 and Comparative Example 1 to corn stalks is detected, and the detection method is: Corn stalks are grown in small sections less than 3 cm, dried at 80°C for 2 hours, weighed 1 kg of dry stalks, and put them into bags with a pore size of 0.1 mm. A total of 80 bags were packed. Randomly take 16 bags with straws, and mix each bag of straws with the compound microbial inoculant in Example 1 with an inoculum of 0.1%; take 16 bags of straws at random, and mix them with an inoculum of 0.1% for implementation The compound microbial inoculum of example 2; Get 16 straw bags, mix in the compound microbial inoculum in embodiment 3 by 0.1% inoculum amount per bag; Get 16 straw bags, mix in by 0.1% inoculum amount in every bag Composite microbial bacterial...

Embodiment 5

[0044] Take 200kg of dried corn stalks, cut them into small sections less than 3cm, divide them into 4 parts on average, each 50kg, add 50kg of water to each part of corn stalks to fully infiltrate, and insert them into Examples 1-3 and Comparative Example 1 respectively The compound microbial agent, the inoculum amount is 50g, the corn stalks inoculated with the compound microbial agent are compacted and sealed, and stacked and fermented, the fermentation temperature is 8°C, and the C / N of the straw is tested, and the test results are shown in the following table Show:

[0045]

[0046]

[0047] From the above test results, it can be seen that the composite microbial bacterial agent in Examples 1-3 uses 0.1% inoculum amount under the environment of 8°C, so that the C / N value of straw stacking and fermentation for 10 days will reach below 14, and the N The content was relatively high, and after 5 days of continuous fermentation, the C / N value did not change much, and the...

Abstract

The invention relates to the technical field of microbial agents, and specifically discloses a composite microorganism, a microbial agent containing the composite microorganism and application of themicrobial agent. The composite microorganism includes bacillus licheniformis, trichoderma longibrachiatum, aspergillus niger, bacillus subtilis, bacillus amyloliquefaciens and bacillus pumilus. The provided composite microorganism and its microbial agent have the advantages that the straw decomposition period is short, the degradation rate is high, the consumption is small, the straw turnover timecan be greatly shortened, and the growth of crops is facilitated.

Description

technical field [0001] The invention relates to the technical field of microbial inoculations, in particular to a composite microbial inoculation, an inoculation containing the composite microbial inoculation and applications thereof. Background technique [0002] my country is a large agricultural country, with an annual output of about 800 million tons of crop straw, which is rich in organic matter, N, P, K and trace elements, and is a very valuable biological resource. Straw returning to the field directly and decomposing returning to the field are two common straw application measures. Straw returning to the field not only reduces the air pollution caused by straw burning, but also makes full use of the nutrients in the straw, which is beneficial to increasing soil fertility, improving soil structure, Increasing crop yields plays an important role. However, the degradation of straw is hindered by the tough cell wall composed of cellulose, hemicellulose and lignin, so th...
