Problems solved by technology

Existing liquid microbial fertilizers generally only contain live bacteria and organic nutrients, basically no inorganic nutrients, so that the effective nutrients of the fertilizer are single, the nutrition is not comprehensive, and the fertilizer effect is not ideal
However, in the absence of microbial preservatives, if a certain amount of inorganic nutrients nitrogen, phosphorus, and potassium, especially nitrogen, are added to the liquid microbial liquid, it will have a strong lethality to the live bacteria in the liquid and affect the survival of the live bacteria. Reduced shelf life of liquid fertilizers

preparation example Construction

[0024] The preparation method of the microbial bacterial liquid comprises the steps of: adding the medium into the first tank and the second tank respectively, sealing them, and sterilizing them; 0.07-0.14Mpa; when the temperature drops to 28-36°C, inoculate the first tank at constant temperature and pressure; ferment for 9-12 hours, add the fermentation liquid of the first tank to the second tank to continue fermentation, the control conditions are the same as the first tank One can, when 90% to 95% of the bacterial cells are formed, the can is put into the can to obtain the microbial bacterial liquid. Wherein, the first tank is a fermented seed tank, and the second tank is a fermenter; the inoculated bacteria are selected from any one or more of Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Bacillus colloidis and Bacillus cereus. The number of calcium in the microbial liquid fertilizer is 1-3 parts, and the number of magnesium-containing parts is 1-3 parts....

Embodiment 1

[0029] Add 300 and 3000L water into the fermented seed tank and fermenter respectively, and then add the Bacillus subtilis culture medium (add 20g glucose, 15g peptone, 5g sodium chloride, 0.5g beef extract to 1L water) into the fermented seed tank and fermenter respectively middle. Close the fermented seed tank and fermenter, turn on the stirring paddle, sterilize with steam under constant stirring, keep the temperature at 121°C for 30 minutes, and thoroughly sterilize pipe fittings such as valves at the same time; Cooling treatment, during the cooling process, the purified compressed air is continuously fed into the fermented seed tank and fermentation tank to ensure that the tank pressure is 0.07-0.14Mpa. When the temperature drops to 28-36°C, take the Bacillus subtilis seeds to the fermentation workshop, inoculate the fermented seed tank with an inoculation amount of 1:10, and ferment after inoculation. The temperature is controlled at 28-36°C, and the tank pressure is con...

Embodiment 2

[0033] Prepare microbial bacterium liquid by the method of embodiment 1;

[0034] 12 parts of Bacillus subtilis bacteria liquid, 14 parts of urea, 10 parts of potassium nitrate, 10 parts of amino acid, 4 parts of EDTA-Ca, 2 parts of magnesium nitrate, 18 parts of molasses liquid.

[0035] Carry out mixing, stirring, canning by the same method in embodiment 1.

[0036] In this embodiment, the number of viable bacteria in the fermented liquid before mixing and stirring was detected to be 680 million / ml. After adding the above-mentioned various substances and mixing and stirring for canning, the number of viable bacteria was sampled and detected to be 587 million / ml. After 6 days, the number of viable bacteria was detected to be 637 million / ml.

Abstract

The invention relates to fertilizer and in particular relates to compound microorganism liquid fertilizer. The compound microorganism liquid fertilizer provided by the invention is prepared from microorganism bacterium liquid, organic biological nitrogen, inorganic fertilizer, median inorganic fertilizer and biological active organic matters. The compound microorganism liquid fertilizer provided by the invention provides needed inorganic nutrients for the growth of crops, beneficial living bacteria in the fertilizer are prevented from being killed by the inorganic nutrients and the survival time of the living bacteria is prolonged.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a compound microbial liquid fertilizer. Background technique [0002] At present, the prevention and control of diseases in our country basically adopts chemical pesticides, which are widely welcomed by farmers because of their strong toxicity, good control effect and low cost. The annual consumption of pesticides in my country is 800,000-1,000,000 tons, ranking first in the world. However, a large number of chemical pesticides are used, one is to cause pesticide pollution to the environment, and the other is to bring about the problem of pesticide residues in agricultural products, which poses a threat to human health. In order to reduce the use of chemical pesticides, agricultural control and biological green control have gradually emerged at home and abroad in recent years. [0003] The development of biological pesticides and microbial fertilizers has become an international trend. Existing...
