Abstract

The invention discloses a selenium-enriched microbial fertilizer and a preparation method thereof, and belongs to the technical field of fertilizers. The fertilizer is prepared from the following rawmaterials in parts by weight: 140-160 parts of a nitrogenous fertilizer, 40-60 parts of a phosphate fertilizer, 80-100 parts of a potash fertilizer, 20-30 parts of a medium-trace element chelating fertilizer, 5-10 parts of charcoal, 1-3 parts of polyaspartic acid, 1-3 parts of seaweed polysaccharide, 1-3 parts of a compound microbial agent, 0.5-1.5 parts of sodium selenite and 3-5 parts of iron nano-particles, wherein the composite microbial agent is prepared by mixing candida utilis, bacillus subtilis and bacillus natto according to a mass ratio of (1.5-2.5):1:(2.5-3.5). According to the invention, absorption efficiency of crops on the selenium is increased mainly by utilizing microbial activities, and meanwhile, nutrient elements such as N, P and K are scientifically proportioned, so that abundant basic nutrient substances are provided for the crops. The selenium-enriched microbial fertilizer disclosed by the invention is reasonable in formula, the preparation process is simple, fertilizer efficiency is remarkable, and safety and environment friendliness are achieved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a selenium-rich microbial fertilizer and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for the human body and an important component of some antioxidant enzymes and selenoproteins in the human body. Studies have shown that selenium has a variety of important physiological functions, such as the protection of cardiovascular and myocardial health, anti-oxidation, anti-cancer and anti-cancer. Selenium deficiency in the human body can lead to various diseases such as Keshan disease, cardiovascular and cerebrovascular diseases, cancer, and high blood pressure. Selenium cannot be produced in the body, and the selenium needed by the human body can only be taken in from food. 72% of China's areas are selenium-deficient or low-selenium areas, and about two-thirds of the country's population has insufficient selenium in...
