Problems solved by technology

[0007] However, the inventors found in production that too many types of microbial strains will bring about complicated preparation process and high preparation cost
However, a variety of microorganisms form an extremely complex symbiotic relationship, and the growth environment requirements of different microorganisms are also very different. Some of them can even secrete antibiotics and require the cooperation of other strains to produce synergistic tolerance. Deconstruction is not explicitly taught by prior art
Therefore, rashly reducing the types of strains will lead to an imbalance of the strains in the entire bacterial agent. For example, the inventors have found that if Cellulomonas is removed, Lactobacillus, Streptomyces and Rhizopus in the bacterial agent will basically not be able to survive. (It may be due to the lack of the growth microenvironment formed by Cellulomonas, or the ability to synergistically resist antibiotics). The final fermentation product is difficult to support the growth of plants on saline-alkali land, and cannot be suitable for saline-alkali land transformation; if Penicillium point is removed, the production Sometimes a large number of miscellaneous bacteria will be produced in the bacterial agent, thereby inhibiting the growth of the bacteria added in the bacterial agent, causing the quality of the bacterial agent between batches to be extremely unstable, so that it cannot be promoted as a commodity at all, and so on. And feet

Embodiment 1

[0061] The production of embodiment 1 microbial bacterial agent

[0062] The present embodiment uses the following strains to prepare microbial inoculum: (1) Cellulomonas faeci ( Cellulomonas fabia ), (2) Bacillus stearothermophilus ( Bacillus sterothermophilus ), (3) Lactobacillus casei ( Lactobacillus casei ), (4) Methanobacter ants ( Methanobacterium formicium ), (5) Methanobacter ruminantum ( Methanobacterium ruminantium ), (6) Thiobacillus thiooxidans ( Thiobacillus thiooxidans ), (7) Thiobacillus ferrooxidans ( Thiobacillus ferrooxidans ), (8) Bacillus licheniformis ( Bacillus licheniformis ), (9) Bacillus polymyxa ( Bacillus polymyxa ), (10) Streptomyces thermophilus ( Streptomyces thermophilus ), (11) common high temperature actinomycetes ( Thermoactinomyces vulgaris ), (12) Thermomonospora curved ( Thermonospora curvata ), (13) brown nitrogen-fixing bacteria ( Azotobacter vinelandii ), (14) Nitrosomonas europeanum ( Nitrosomonas europeae ), ...

Embodiment 2

[0065] Example 2 Production of saline-alkali soil improver

[0066] 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.

[0067] 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 that the temperature d...

Embodiment 3

[0070] Example 3 Improvement example of saline-alkali land in Tianjin Binhai New Area

[0071] Tianjin Binhai New Area is located on the west coast of Bohai Bay and has the entire 154-kilometer coastline of Tianjin. The terrain in this area is flat (the slope is 1 / 10000 to 1 / 10000), the altitude is only 1 to 2.5 meters, and the soil is compact; the water level of the surface pore water (groundwater) is only 0.5 to 1.0 meters, and the salinity is greater than 30 grams per liter; saline-alkali land accounts for 86.3% of the total land area, with sparse vegetation, high soil salinity, difficulty in soil desalination, and fragile ecosystems, which are considered "forbidden areas for plants".

Abstract

The invention provides a live microbial composition used for producing a saline land improvement agent in fermentation mode. In addition, the saline land improvement agent produced by the microbial composition in fermentation mode and the like is further provided. The saline land improvement agent is used in methods for improving saline land and improving plant survival rate in saline land and is especially suitable for coastal native saline land.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation. Specifically, the invention relates to a microbial composition, which reduces the number of strains and reduces the production cost without substantially reducing the stability and adaptability of the microbial agent produced therefrom, but The saline-alkali land improver produced by fermentation can support the growth of plants on saline-alkali land, thereby improving the saline-alkali land. In addition, the present invention also relates to the saline-alkaline soil improvement agent produced by the fermentation of the above-mentioned microbial composition and its application and method. [0002] Background of the invention [0003] Saline-alkali land (saline soil) is widely distributed in more than 100 countries and regions in the world, with an area of ​​nearly 1 billion hectares in the world, of which China alone has 36.3 million hectares, accounting for nearly 5% of my count...
