Mineral fertilizer containing complex microbial community and preparation method thereof

Abstract

The present invention relates to a mineral fertilizer containing complex microbial community and a preparation method thereof. The mineral fertilizer is prepared in a method that bacillus subtilis and bacillus mucilaginosus are inoculated, cultured, fermented and adsorbed to form a complex microbial inoculant; and dolomite dust, manganese ore fines, zinc sulfate, bentonite and the complex microbial inoculant are stirred and mixed in parts by weight in a stirrer for 1-2 hours, and granulated in a pelletizer, dried in a dryer and then sieved in a sieve at the temperature of 10-55 DEG C and the pH value of 5-10.5, thus forming the mineral fertilizer containing complex microbial community. The mineral fertilizer is capable of nourishing crops during growth and controlling crops physiological disturbance caused by calcium and magnesium deficiency; meanwhile, the mineral fertilizer has high suitability, stable performance, functions of nitrogen fixation, phosphate solubilization and potassium solubilization. The mineral fertilizer changes parasitifer specificity for nitrogen fixation, has no side effect on human and livestock and has no pollution on soil. Crops fertilized with the mineral fertilizer meet all requirements of green food, the crop production is increased and the crop quality is improved.

Description

technical field [0001] The invention relates to a mineral fertilizer containing complex microbial flora, which can provide nutrition for crop growth; prevent and treat physiological diseases of crops caused by calcium and magnesium deficiency; meanwhile, the complex microbial flora has strong adaptability and performance It is stable and has multiple functions such as nitrogen fixation, phosphorus dissolution, and potassium dissolution. It can change the specificity of nitrogen fixation hosts, has no side effects on humans and animals, and does not pollute the soil. quality. Background technique [0002] Chemical fertilizers have laid a material foundation for the production and development of modern agriculture and the protection of human food security. However, the low utilization rate of chemical fertilizers and the resulting high environmental risks have always been a major problem plaguing the world. Therefore, countries all over the world are actively exploring ways a...
