Problems solved by technology

Among them, the sodium alginate embedding method is widely used for its advantages of simple operation, high particle strength after embedding, non-toxicity to microorganisms and good mass transfer performance, but at the same time, they have poor antimicrobial decomposition performance and low mechanical strength. The activity and mass transfer performance of the coupling agent will decrease again after the stabilization treatment

Embodiment Construction

[0018] A microbial immobilized organic fertilizer is prepared by the following method:

[0019] (1) Expose the silkworm excrement to the sun for 2 days, collect it, pulverize it and pass it through a 60-mesh sieve, fully mix it with an equal volume of 20% phosphoric acid solution, soak it for 15 minutes, filter it, remove the filtrate, and send the material into a high-temperature furnace to Heat up to 400°C at 20°C / min and react for 30 minutes. After completion, take it out and cool to room temperature, wash with water, dry and pulverize to obtain powder for later use;

[0020] (2) Mix seaweed, coconut shell, and medical stone powder in a mass ratio of 7:5:1 and put them into a compost tank with ventilation holes on the side, add water twice the total weight, mix well, and then retting and fermenting for 3 weeks. During the period, manual turning is carried out every 7 days. After the fermentation is completed, the fermented material is crushed and filtered, and the obtained ...

Abstract

The invention discloses microbial immobilized organic fertilizer and a preparation method thereof. The fertilizer is prepared from raw materials including silkworm shit, algae, coconut shells, medical stone powder, ferric chloride, an EM fungicide and the like. Degradation of organic matter in soil can be accelerated, the content of available nutrients in plants is increased, and the fertilizer has the characteristics of organic fertilizers as well as advantages of microorganisms, can be applied to various kinds of crops and soil, cannot damage the soil structure or contaminate soil, is harmless to people and livestock, improves the soil fertility, can prevent soil-borne diseases, promote growth of the crops, increase the yield and improve the quality of agricultural products and has relatively high social benefits and economic value.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microorganism-immobilized organic fertilizer and a preparation method thereof. Background technique [0002] my country is not only a big agricultural country, but also the largest fertilizer importer, nitrogen fertilizer producer and fertilizer user in the world. Fertilizers play a pivotal role in my country's agricultural production, but the extensive use of chemical fertilizers has caused soil compaction, decreased soil fertility, increased soil-borne diseases, and reduced the quality of agricultural products. Therefore, there is an urgent need to develop more environmentally friendly fertilizers to replace chemical fertilizers to achieve high-quality and high-yield crops. Microbial fertilizer refers to a specific product that contains a certain amount of live beneficial microorganisms, regulates plant growth rate, promotes crop yield increase, and improves plant rhizos...
