Problems solved by technology

The number of effective viable bacteria in microbial fertilizers is an important indicator of product quality. If the number of effective viable bacteria does not meet the standard, the quality of the product cannot be guaranteed. It reflects that the application effect is unstable. The main reason is the problem of strains. After being used as a microbial strain agent, the survival ability during the preservation process is reduced, and the survival time is shortened
In the process of production and use, the activity of the bacteria is reduced, the production performance is weakened, the reproduction speed is slowed down, and the stress resistance is poor.

Embodiment 1

[0045] Embodiment 1: Utilize traditional method to carry out fermentation preparation microbial strain agent to Xin Potassium No. 1

[0046] Medium: 0.5% starch, 0.1% sucrose, 0.2% dipotassium hydrogen phosphate, 0.1% ammonium sulfate, 0.05% magnesium sulfate, 0.001% ferric chloride, 0.01% calcium carbonate, 0.02% yeast extract, pH7.2-7.4.

[0047] After the strain is activated, insert it into 1000ml of the above-mentioned culture medium, culture it in a Erlenmeyer shaker flask at 160RPM at 37°C for 16 hours, then inoculate it into a 200L seed fermenter (still the same culture medium) according to 1% inoculum size, ventilate, and cultivate at 37°C 16 hours, then received in 2000L fermenter (still the same culture medium) by 10% inoculum, warming up to 42 ℃ after cultivating for 20 hours at 37°C and cultivating for 10 hours, stop fermentation after 80% thalline produces spores. Detect the bacterial concentration and reach 10 9 , and then mix it with high-quality peat powder (c...

Embodiment 2

[0048] Embodiment 2: Utilize the method provided by the invention to ferment No. 1 new potassium to prepare microbial strain agent

[0049] Activate the strains first, then rinse the slope with 5ml of sterile water to form a bacterial suspension, and put the bacterial suspension into a 500ml triangular flask containing 100ml of new 1 liquid medium, and use a shaker to cultivate for 18 hours. 37°C, 180-200rpm, detect the bacterial concentration, when the concentration reaches 10 8 Order of magnitude, proceed to the next step;

[0050] Transfer 100ml of bacterial solution from a 500ml conical flask into a 2000ml conical flask, which contains 700ml of new 2 medium, and cultivate it on a shaker for 20 hours at 37°C, 180-200rpm; Concentration up to 10 8 Order of magnitude, proceed to the next step;

[0051] Put the bacterial solution in the 2000ml Erlenmeyer flask into 1m 3 In the fermenter, the intake volume is 6 liters, the fermenter contains 500L of new 3 medium, the ferment...

Embodiment 3

[0053] Embodiment 3: Under the condition that does not stockpile for a long time, carry out bacterial count detection to the microbial strain preparation that utilizes traditional method to prepare

[0054] The live bacteria content in the microbial strain agent was detected by the conventional dilution plate counting method. Weigh 1 gram of microbial strain agent (stock for half a month), dissolve it with sterile water, dilute it with sterile water until the number of bacteria is 20-100 / ml, and then pipette 1ml of the diluted solution into a sterile petri dish , add an appropriate amount of new 1 medium (slant medium), mix well and solidify, incubate upside down in a 37°C incubator for 48 hours, count the colonies on the plate, repeat more than three times, and multiply the average value by the one gram of microbial strains The number of milliliters when the agent is diluted so that the cell concentration is 20-100 / ml is the number of strains per gram of the microbial strain ...

Description

technical field [0001] The technical solution of the present invention belongs to the field of agricultural fertilizers, specifically, belongs to the field of microbial fertilizers in the field of biological fertilizers, and belongs to the field of C05F 11 / 08 according to the International Patent Classification. Background technique [0002] my country has a large population but little arable land, and the arable land decreases year by year with the growth of population and the development of industry and cities. According to the statistics of relevant departments, the average population of our country increases by 16 million every year, while the cultivated land decreases by 4 million mu every year. In 1950, the population was 550 million, the arable land was 1.65 billion mu, and the per capita arable land was 2.99 mu. In 1980, the per capita arable land was 1.51 mu. In 1990, the per capita arable land dropped to 1.1 mu. Acre level. Therefore, the only feasible way to inc...
