Long-acting biofertilizer

Abstract

The invention relates to a long-acting biofertilizer which is composed of the following components in parts by weight: 6-10 parts of bone meal, 5-9 parts of shale, 4-8 parts of plant ash, 7-12 parts of organic fertilizer, 3.5-8 parts of clay, 4.5-7 parts of composite microbial inoculant, 4.8-7.5 parts of phosphate, 3.2-5.7 parts of lysine, 2.5-6 parts of potassium chloride, 1.3-4 parts of sodium molybdate dihydrate, 0.6-1.5 parts of chelator and 3-5 parts of minor element. The fertilizer can display the function for a long time and improve the soil. The added biological microbial inoculant loosens the soil, enhances the crop absorptivity and improves the yield and quality of the product.

Description

technical field [0001] The invention relates to a long-acting biological fertilizer. Background technique [0002] In recent years, when people use fertilizers, they use a lot of inorganic fertilizers. Although the yield is increasing year by year, it has a great impact on the soil. The application of inorganic fertilizers is simple and quick. Now farmers rely heavily on the application of inorganic fertilizers. The application of fertilizers is not paid enough attention. Some farmers only apply inorganic fertilizers almost all the year round, and never apply other fertilizers. However, due to long-term use, the soil is hardened, the fertility of the land decreases, the output of food and vegetables decreases year by year, and the quality of the products cannot be guaranteed. In addition, as people's awareness of health increases, people demand more organic products. It also puts forward higher requirements for fertilizers, not only to ensure the nutritional content, but al...
