Embodiment 1

[0019] Embodiment 1: the preparation of microbial bacterial agent

[0020] Utilize selective culture medium Ashubei culture medium (mannitol 1%, potassium dihydrogen phosphate 0.02%, magnesium sulfate 0.02%, sodium chloride 0.02%, calcium sulfate 0.01%, calcium carbonate 0.5%, pH7.0) from environment The microorganisms with nitrogen-fixing ability were screened, and the nitrogen-fixing ability was determined by acetylene reduction method, and the microorganisms with strong nitrogen-fixing ability were selected.

[0021] Utilize inorganic phosphorus selective medium (sodium chloride 0.03%, magnesium sulfate 0.03%, potassium chloride 0.03%, ammonium sulfate 0.05%, ferrous sulfate 0.003%, manganese sulfate 0.003%, calcium phosphate 0.5%, glucose 1% , pH 7.0) screened microorganisms with phosphorus-dissolving ability from the environment, measured their phosphorus-dissolving ability by molybdenum-antimony anti-colorimetry, and selected microorganisms with strong phosphorus-dissolv...

Embodiment 2

[0026] Embodiment 2: the preparation of microbial compound fertilizer

[0027] The microbial bacterial agent prepared in Example 1 is adsorbed with humic acid, and the adsorption ratio volume (L) / mass (kg) is bacterial liquid: humic acid=1:34, then stir evenly. Stirring after humic acid adsorption is based on looseness and no agglomeration. After drying in the shade, add 30% chemical fertilizer. The components and ratios of fertilizers are: Potassium dihydrogen phosphate: Diammonium phosphate is 1:4.44.

Abstract

The invention provides a microbial agent including ensifer adhaerens, acinetobacter calcoaceticus and flavobacterium chungangense. The invention also provides a compound fertilizer including the microbial agent, humic acid and an inorganic fertilizer, wherein the number of the microbial agent is 1-500000000/g, and the mass ratio of humic acid to the inorganic fertilizer is 7:3. The inorganic fertilizer contains three elements of nitrogen, phosphorus and potassium, and the ratio of N, P2O5 and K2O is 8:30:4. The microbial compound fertilizer is rich in nutrition and comprehensive in functions, and can significantly improve the yield and quality of cucumber. Compared with a common chemical fertilizer, under a condition of the same amount of input, the microbial compound fertilizer can allows the yield to be increased by 10-60% and the soluble sugar to be increased by 10-20%.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a microbial compound fertilizer and a preparation method thereof. Background technique [0002] The extensive use of chemical fertilizers has made food safety, ecological environment protection and sustainable use of resources the three major issues facing the development of agriculture in the world today, and is also a major issue related to the national economy and people's livelihood in our country. Microbial fertilizers have the characteristics of fertilizing soil fertility, improving the utilization rate of chemical fertilizers, reducing the content of nitrate nitrogen, heavy metals, and pesticides in agricultural products, improving the quality and safety of agricultural products, purifying and restoring the soil ecological environment, and improving the stress resistance of crops. The promotion and use of microbial fertilizers is an important supp...
