Embodiment 1

[0031] A preparation method of high nitrogen-containing compound microbial fertilizer, the method comprises the following steps:

[0032](1) Add 39.12kg of urea, 18kg of microbial inoculum agent, 12kg of organic material and 50.88kg of water into the fermentation vessel and stir evenly before fermenting. Wherein, the microbial strain agent is Bacillus subtilis (Bacillus subtilis), and its effective number of viable bacteria is greater than or equal to 3 billion / ml. The preparation of the strain can be done by conventional operations in the field. The organic material contains 10wt% of fish meal and 25wt% of soybean meal %, corn flour 30wt%, peat 35wt%;

[0033] (2) On the 17th day of fermentation, it is found that a large amount of gas is produced in the container, and the weight percentage concentration of ammonium nitrogen in the detection material is less than 2%, that is, the fermentation is considered to be completed. Potassium dihydrogen phosphate is added to the fermen...

Abstract

The invention relates to a high-nitrogen-concentration composite microbial fertilizer and a preparation method thereof, wherein the raw materials of the high-nitrogen-concentration composite microbial fertilizer comprise the following components in percentage by weight (wt%): 10-33% of urea, 5-20% of microbial strain agent, 10-40% of organic materials and 30-70% of water. The preparation method comprises the following steps of: adding the materials to a fermentation container, stirring evenly, fermenting for 15-25 days, adding appropriate monopotassium phosphate when lots of gas gives off and after detecting that the weight percentage concentration of ammonium nitrogen of the materials fermented completely is lower than 2%, thereby obtaining the composite microbial fertilizer in liquid or solid form, and finally, weighing and packaging. According to the invention, active small molecular amide nitrogen is transformed and fixed into slow-release macromolecular organic nitrogen through biochemical reaction of microorganisms; therefore, the content of nitrogen nutrient in the composite microbial fertilizer is improved and the activity and amount of microorganisms also are guaranteed; besides, the utilization rate of urea is improved and pollution on the natural environment caused by easy loss of nitrogen is reduced. As a result, a novel, long-acting, environmentally-friendly composite microbial fertilizer is developed.

Description

technical field [0001] The invention relates to a compound microbial fertilizer and a preparation method thereof, in particular to a high-nitrogen compound microbial fertilizer and a preparation method thereof. Background technique [0002] Compound microbial fertilizer consists of two parts, one is specific microorganisms, and the other is nutrients, which is a complex of the two components. The specific functional microorganisms in the compound microbial fertilizer can form dominant beneficial bacteria in the rhizosphere of crops. Due to their life activities, they can not only release the fixed phosphorus and potassium nutrients in the soil, but also fix and transform the nitrogen nutrients in the air. , and at the same time stimulate the growth of crops and inhibit the role of crop pathogenic bacteria. The nutrient part of the compound microbial fertilizer can not only provide plant nutrition but also improve the soil, and it is also the carrier of functional microorgan...
