Embodiment 1

[0027] This embodiment is an example of preparation of a degrading bacteria composite bacterial agent for degrading straw, and its specific steps are as follows:

[0028] (1) Degrading bacteria compound bacterial agent

[0029] Use an inoculation loop to take ZL-2 [Brevibacterium] frigoritolerans, Lactobacillus acidophilus, Beijerinckia indica, Paenibacillus mucilaginosus N6 , Rhodopseudomonas sp. (Rhodopseudomonas sp.) and Flavobacterium johnsoniae (Flavobacterium johnsoniae). The ratio of the colony numbers of Lactobacillus acidophilus, Bayeringia indica, Paenibacillus colioids N6, Rhodopseudomonas and Flavobacterium johnsonii is 0.2~0.5:1:1~1.5:0.5~1: 1:0.3~0.5, more preferably 0.3:1:1.5:0.7:1:0.5.) Activation and expansion culture test, 25 ℃, 120r / min under the conditions of shaking culture for 24 hours; draw activation by volume ratio 1:1 After the bacterial liquid was put into the corresponding liquid fermentation medium, it was shaken and cultured for 72 hours to the ...

Embodiment 2

[0043] This embodiment is a preparation example for making organic fertilizer for livestock and poultry manure composting. The method of this embodiment includes the following steps:

[0044] (1) The test cow dung and corn stalks are from the cooperation unit of Qingdao Zhonghai Environmental Engineering Co., Ltd. and local farmers. Mix them according to the method of cow dung: corn stalks: bacterial agent = 6:3:1, and stir evenly (the C / N ratio is 24 , C / P ratio is 117); At the same time, set up 6 groups of control experiments with only adding a single bacterial agent. Add pure water, stir evenly, adjust the water content of the mixed material to about 55%, and obtain the compost raw material.

[0045] (2) Stack the above-mentioned compost raw materials into a trapezoidal stack with a length of 12m, a width of 5m, and a height of 1.5m, cover with the NCS intelligent molecular membrane material of Qingdao Zhonghai Environmental Engineering Co., Ltd. and compact the surrounding...

Embodiment 3

[0050] Present embodiment is that the organic fertilizer that obtains with embodiment 2 is used for planting rapeseed and carries out the fertilization test of organic fertilizer, and the method of present embodiment comprises the following steps:

[0051] 1. Basic conditions of the test soil

[0052] The soil for testing was taken from the brown soil 0-20cm of a cultivated land in Jimo District, Qingdao City, Shandong Province. Its basic physical and chemical properties are shown in Table 2, and passed through a 5mm sieve for use. The pot experiment was carried out at Qingdao Zhonghai Environmental Engineering Co., Ltd.

[0053] Table 2 - Basic physical and chemical properties of soil

[0054]

[0055] 2. The tested crop: rapeseed, the variety is Suzhou Green.

[0056] 3. Test treatment

[0057] 1) Take the soil back through a 5cm sieve, put it into a flower pot with a diameter of 30cm and a height of 70cm, and pack 10kg of soil in each bucket. Set up three treatment c...

Abstract

The invention relates to a straw rapid degradation microbial inoculum composition. The composition comprises 10%-20% of a degradation bacterium complex microbial inoculum, 40%-50% of peanut straw, 10%-15% of peanut shells, 20%-25% of fruit and vegetable residues and 20%-30% of earthworm cast. The degrading bacterium complex microbial inoculant is prepared from ZL-2 brevibacterium friariorum, lactobacillus acidophilus, Beijerinckia indica, paenibacillus mucilaginosus N6, Rhodopseudomonas and flavobacterium johnsonii; and the straw rapid degradation bacterial agent composition is combined with a film mulching composting technology for use, so that a fermentation heap body can be rapidly heated, the composting fermentation efficiency can be greatly improved, the composting decomposition degree is remarkably improved after fermentation is finished, the composting fermentation effect is improved, the content of organic matters in the produced fertilizer is higher (55.8%), the nutrients are more comprehensive, the absorption of plants is more facilitated, the yield of the rape can be increased by 57.5%, and the quality of the rape is effectively improved.

Description

technical field [0001] The invention relates to the fields of resource utilization of agricultural waste and treatment of livestock and poultry manure, in particular to a composition for preparing straw rapid degradation bacteria agent, a preparation method and an application. Background technique [0002] my country is rich in agricultural waste resources such as crop straws, livestock and poultry manure. By 2016, the theoretical resources of crop straws reached 984 million tons, of which three types of crop straws, corn, rice and wheat, accounted for 83.51% of the total. The theoretical output of straw and livestock and poultry manure will reach 2.88 billion tons. Although various punitive measures have been issued for straw burning across the country, studies have shown that more than half of the straw is burned every year, which not only endangers air quality, poses a huge threat to the ecological environment, but is also a serious waste of resources. [0003] Crop straw...
