Antibacterial peptide active organic fertilizer and preparation method thereof

Abstract

The invention relates to antibacterial peptide active organic fertilizer and a preparation method thereof and belongs to the technical field of agricultural fertilizer. The fertilizer consists of livestock and poultry excrement, silkworm excrement and a microbial fermenting agent. The preparation method for the fertilizer comprises the following steps: 1) weighing the livestock and poultry excrement, the silkworm excrement and the microbial fermenting agent according to the weight ratio, mixing, adjusting the water content of the mixture to 55 to 65 percent, adjusting the pH value to be 5.0 to 8.0, and adjusting the C / N value to be 20 to 30; 2) performing primary stacked fermentation; 3) performing secondary stacked fermentation; and 4) screening the fermented organic fertilizer obtained in the step 3) to remove impurities, pelleting, shaping, discharging, drying, cooling, removing dust, detecting and packaging to obtain the antibacterial peptide active organic fertilizer. Compared with control, the antibacterial peptide active organic fertilizer can increase the yield by 20.1 to 25.3 percent when applied in the fields of fruits, vegetables, grain and oil, flowers and trees, tea and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an antimicrobial peptide active organic fertilizer and a preparation method thereof. Background technique [0002] With the development of the breeding industry, the pollution of its excrement to the environment is becoming more and more serious. Therefore, how to turn livestock and poultry excrement from waste into wealth and start a recycling industry has attracted the attention of industry insiders. [0003] Traditional organic fertilizers have a long fermentation period, often due to insufficient fermentation time and incomplete fermentation, resulting in a large number of harmful bacteria. Therefore, extensive application of traditional organic fertilizers often results in the presence of harmful bacteria in the soil, as well as soil compaction and nutrient loss. [0004] Although silkworm excrement can inhibit the reproduction of harmful bacter...

Problems solved by technology

[0003] Traditional organic fertilizers have a long fermentation period, often due to insufficient fermentation time and incomplete fermentation, there are a large number of harmful bacteria

Therefore, extensive application of traditional organic fertilizers often results in the presence of harmful bacteria in the soil, as well as soil compaction and nutrient loss

[0004] Although silkworm excrement can inhibit the reproduction of harmful bacteria and at the same time fix nitrogen, decompose phosphorus, and dissolve potassium, there are overall disadvantages in the following aspects when using silkworm excrement alone as an organic fertilizer: high cost, excessive temperature rise during fermentation will lead to nitrogen loss, ammonia gas The generation of PH leads to too high, which limits its wide application

[0005] However, in the prior art, there is no antimicrobial peptide active organic fertilizer and preparation method thereof composed of silkworm excrement and excrement of livestock and poultry.
