Embedded bacterium mulberry fertilizer and preparation method thereof

Abstract

The invention discloses an embedded bacterium mulberry fertilizer and a preparation method thereof. The fertilizer is composed of microbial inoculum, agar powder, potassium sulfate, urea, ammonium humate, potassium permanganate, calcium-magnesium-phosphate fertilizer, clay, microbial embedding medium, and a proper amount of water. Research results show that a mixture, which is prepared by mixing sodium alginate and polyvinyl alcohol according to a certain ratio, has a prominent advantage on embedding microbes; moreover, an ionic modifier and resin monomers are added to increase the mechanical strength of embedding, embedding speed, and living rate of live bacteria; the chemical components are grinded at first and then wetted, then processed chemical components are mixed with embedded particles, which are composed of sodium alginate and resins, so the fertilizer has a certain absorbing performance and sustain-released performance, the fertilizer loss is reduced, and the fertilizer utilization rate is increased by adding soil microbes.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fungus-embedded mulberry fertilizer and a preparation method thereof. Background technique [0002] Microbial fertilizers can partially replace chemical fertilizers, reduce the loss and waste caused by their extensive use, and even cause soil salinization and environmental pollution. The common dosage forms of microbial fertilizers are either bacterial liquids received after fermentation, or made with peat as a carrier The two formulations are more convenient in preparation, but both have many disadvantages, such as after the bacterial agent is applied to the soil, the bacteria are directly exposed to the open state, which is easy to cause the death of the bacteria. Proliferate to a certain level within a certain period of time, which is not easy to achieve. The embedding method is one of the cell immobilization technologies developed in recent years. It embeds...
