Embodiment 1

[0037] The production of embodiment 1 microbial bacterial agent

[0038] The present embodiment uses the following strains to prepare microbial agents: (1) Acetobacter striatum ( Acetobacter aceti ), (2) Beauveria bassiana ( Beauveria bassiana ), (3) Azospirillum brasiliensis ( Azospirllum brasilense ), (4) Nocardia cellulosus (Nocardia cellulans ), (5) Bacillus jelly-like (Bacillus mucilaginosus) , (6) Metarhizium anisopliae ( Metarhizium anisopliae ), (7) Trichoderma chrysogreen (Trichoderma aureoviride) , (8) Spirulina platensis ( Arthrospira platensis ), (9) Cellulomonas leguminosa ( Cellulomonas fabia ), (10) Bacillus stearothermophilus ( Bacillus sterothermophilus ), (11) Lactobacillus casei ( Lactobacillus casei ), (12) Methanobacterium formici ( Methanobacterium formicium ), (13) Methanobacter ruminantum ( Methanobacterium ruminantium ), (14) Thiobacillus thiooxidans ( Thiobacillus thiooxidans ), (15) Thiobacillus ferrooxidans ( Thiobacillus...

Embodiment 2

[0041] Example 2 Production of secondary saline-alkali desertification improver

[0042] Take cow dung with a water content of 65% (weight ratio) (if the water content is insufficient, you can add water) and crushed rice bran with particles smaller than 5mm, mix them evenly at a mass ratio of 85:15, and make the mixed cow dung and rice bran There is no agglomeration above 40mm.

[0043] Then, the mixture of 1 ton of above-mentioned cow dung and rice bran is mixed with the microbial inoculant produced in 1kg 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 t...

Embodiment 3

[0045] Example 3 Improvement example of secondary saline-alkali land in Tianjin Binhai New Area

[0046] Our previous patented technology has achieved good results on the coastal saline-alkali land of Tianjin Binhai New Area, but the effect on the secondary saline-alkali land caused by the degradation of non-coastal originally cultivated land is not significant, and the survival rate of seedlings is not ideal. Therefore, we use the new research and development The secondary saline-alkali desertification improvement agent granule was used to carry out the improvement test on similar secondary saline-alkali land (and desertification phenomenon) that was not modified.

[0047] The test started on April 5, 2012, and was applied by Tianjin TEDA Landscape Construction Co., Ltd. and Tianjin Haibin Avenue Construction and Development Co., Ltd. (during which no foreign soil was applied), that is, the secondary salt prepared in Example 2 was mixed into the surface 20cm soil Alkaline d...

Abstract

The invention provides a microbial composition comprising acetobacter aceti, beauveria bassiana, azospirllum brasilense, nocardia cellulans, bacillus mucilaginosus, metarhizium anisopliae, trichoderma aureoviride and the like. The microbial composition can be stably combined in a microbial agent, can survive for a long term in a plurality of improved soil to play a role, is good in adaptation of improving soil/land and especially can be used for effectively improving a plurality of soil, such as secondary salinization land, desertification soil.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation. Specifically, the present invention relates to a microbial composition. Although the number of strains is large, the bacterial agent produced by it is stable. The combination of these more strains enables the improvement of soil / land It has good adaptability and can effectively improve various soils such as secondary saline-alkali land and sandy soil. Background technique [0002] Irrational cultivation, including excessive reclamation and planting, unreasonable irrigation and / or excessive application of chemical fertilizers (especially long-term use of a single type of chemical fertilizer), can easily cause soil salinization and even desertification, that is, the formation of secondary saline-alkali land and / or desertification land. my country has a long history of farming, and there is a lot of historical accumulation of saline-alkali land and desertified land. In particular, th...
