Problems solved by technology

[0002] Agricultural pollution has become the largest environmental pollution in our country. Now the organic matter content of soil in our country is decreasing from 7% to 11% in the early days of the founding of the People's Republic of China to below 3%. The vicious cycle of the waste caused irreparable losses. Every year in the busy season of summer harvest and autumn, the utilization efficiency of straw and other organic resources is very low. It is often solved by simple and trouble-free incineration, which burns the surface of the soil, wastes resources and pollutes Excessive use of chemical fertilizers, undecomposed and unabsorbed nutrients by rainwater will flow into rivers and lakes, resulting in excess nutrients in water quality and serious pollution. Extensive use of chemical fertilizers and pesticides will pollute agricultural products and leave a legacy for human survival and life. There are hidde

Abstract

The invention discloses a selenium-enriched microbial organic fertilizer and a preparation method thereof. The selenium-enriched microbial organic fertilizer comprises the following raw materials in parts by weight: 12-18 parts of a pre-fermented material, 6-10 parts of mineral substances, 0.5-0.8 part of bacillus subtilis 10147, 30-40 parts of edible mushroom leftovers, 5-10 parts of kiln dust and 15-20 parts of biogas water; the pre-fermented material comprises the following raw materials in parts by weight: 10-20 parts of fly maggots, 1-3 parts of biogas water, 3-5 parts of molasses, 0.1-0.2 part of sodium selenite and 0.1-0.2 part of bacillus subtilis 10147; the mineral substances comprise the following raw materials in parts by weight: 40-60 parts of powdered rock phosphate, 40-60 parts of coal gangue and 1-3 parts of silicon powder. The bacillus subtilis 10147 is adopted in the selenium-enriched microbial organic fertilizer disclosed by the invention to enrich a large amount of organic selenium in the organic fertilizer; in addition, the organic fertilizer has the functions of improving soil, preventing diseases and protecting the environment, and thus great convenience is brought to agricultural production.
