Abstract

The invention relates to microorganism controlled-release fertilizer. The microorganism controlled-release fertilizer is composed of, by weight, 9%-30% of chitin, 0.3%-6% of bacillus subtilis additives, 6%-15% of alginic acid, 10%-15% of nitrogenous fertilizer, 8%-10% of phosphatic fertilizer, 10%-15% of potash fertilizer and the balance epoxy resin, wherein the total number of effective viable bacteria of the bacillus subtilis additives is equal to or larger than 200 million spores per gram. According to the microorganism controlled-release fertilizer, the synergistic effect of the chitin, the bacillus subtilis additives and the alginic acid is good, the controlled-release effect is achieved, the nutrient requirements of crops during the whole growing period can be met through one-time application of the fertilizer, the cost of fertilization operations is greatly reduced, and the safety is good.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers. Background technique [0002] Microbial fertilizers are a type of microbial living products that use microbial life activities and their products to cause specific fertilizer effects on crops. At present, microbial fertilizers are used to fertilize soil, improve fertilizer utilization, and inhibit crops from absorbing nitrate nitrogen, heavy metals, and pesticides. It plays an irreplaceable role in purifying and repairing soil, reducing the occurrence of crop diseases, promoting the utilization of crop straw and urban waste, protecting the environment, and improving the quality of crop products and food safety. The effect of the existing microbial fertilizer is unstable, the cost performance is not high, and the popularization is weak. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cost-effective microbial controlled...
