"Coal gangue compound microbial new fertilizer" successfully tested in Changzhi
Recently, it was learned from the press conference held by Shanxi Lu'an Vocational and Technical College that they were jointly developed by the Academician of the Chinese Academy of Engineering, Niu Yuping, Director of the Institute of Electron Optics at Shenzhen University, and the Cooperative Development between Lu'an Vocational and Technical College and Beijing Forestry University. The high-tech project coal gangue compound microbial new fertilizer has been successfully tested in Changzhi City. The long-term accumulation of large quantities of coal gangue in the open air can cause water quality in the area to decline, causing environmental hazards such as acid rain. How to turn waste into treasure, and the development and utilization of coal gangue and similar wastes have become an important scientific research topic in the scientific community. In recent years, foreign scientists have discovered through research that coal gangue contains a variety of microbial fertilizers necessary for the growth of crops. After nearly three years of hard work, the project research group consisting of Beijing Forestry University and Lu'an Vocational and Technical College has completed the Feasibility Study Report on the Use of Coal Gangue to Produce a New Type of Biological Fertilizer Project and has comprehensively analyzed the coal of Wangzhuang Coal Mine. Meteorite samples were screened for two types of strains suitable for production of biological fertilizers using coal gangue as a substrate. Six tons of coal gangue compound microbial fertilizers were trial-produced and green pepper and millet fertilizer formulations were developed. Successful tests in the field were developed. The coal gangue compound microbial fertilizer production process, applied for the patent of the coating process technology to the State Intellectual Property Office and put forward the patent application of coal gangue compound microbial fertilizer. Tested by the Grain Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture, the use of gangue compound microbiological fertilizers for green pepper, corn and millet increased 9.3%, 0.4% and 10.3%, respectively, and the VB1 content increased 103.1%. The content of crude fiber, nitrate, etc. is greatly reduced. The gangue compound microbial fertilizer has the effects of overcoming the environmental pollution caused by the application of chemical fertilizers, long-term fertilizer efficiency, and decline in crop quality, and has the advantages of being non-toxic, non-polluting, broad-spectrum, high-quality, and high-efficiency.
