Embodiment 1

[0022] A mulberry fertilizer for embedding bacteria is characterized in that it is made of the following raw materials in parts by weight (kg): microbial strain agent 10, agar powder 4, potassium sulfate 12, urea 40, ammonium humate 22, permanganate Potassium 15, calcium magnesium phosphate fertilizer 30, clay 45, microbial embedding agent 15 and appropriate amount of water;

[0023] The microbial embedding agent is composed of liquid a and liquid b at a ratio of 3:1. Liquid a is mixed with sodium alginate 8 and polyvinyl alcohol 8 and added to 50 times its weight in water, heated at 70-80°C and stirred to dissolve It is prepared and kept at 28°C for later use; liquid b is anhydrous calcium chloride 6, peat 5, limestone powder 15, linseed oil 10, acrylate 16, ethanol 15 and an appropriate amount of water; the preparation method is to mix ethanol in a reaction kettle Add water to dilute 6-8 times, then add acrylate, heat to 80-100°C and stir to dissolve, then add anhydrous calc...

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...
