Method used for preparing algae particle potassium fertilizer via compound microorganism fermentation

Abstract

The invention relates to a method used for preparing an algae particle potassium fertilizer via compound microorganism fermentation. The method comprises following steps: fresh marine algae plants are subjected to washing, impurity removing, immersing, and pulping so as to prepare seed fermentation broth of fermentative strain respectively; an algae base material is inoculated with the seed fermentation broth in a plurality of times so as to realize fractional fermentation; a fermentation product is prepared into an algae functional microbial inoculum further; mild impact pelletizing is adopted to realize combination the algae functional microbial inoculum with chemical fertilizer raw materials so as to obtain the algae synergistic-effect potassium fertilizer particle rich in algae extract and special-effect composite fermentative strain. It is shown by experiment that the technical effect of the compound fractional fermentation is better than that of single strain fermentation, and the fertilizer effect of the algae functional potassium fertilizer is obviously better than that of conventional potassium fertilizer products.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a method for preparing seaweed granular potassium fertilizer by compound microorganism fermentation. Background technique [0002] Excessive application of chemical fertilizers has caused a series of serious problems such as soil structure damage, reduction of natural biodiversity and ecosystem stability, eutrophication of rivers and lakes, and decline in the quality of agricultural products. Most of the potash fertilizers currently on the market are compounded with chemical fillers and lack functional synergistic ingredients. The compound fertilizers and blended fertilizers prepared from this raw material cannot bring any benefits to the improvement of the soil environment and the sustainable development of agriculture. A vicious circle will form. The development of modern agriculture and the realization of sustainable agricultural development will inevitably...

Problems solved by technology

[0003] The research and development model of this type of fertilizer in my country is still relatively traditional, and the equipment and technology are insufficient. It still has not become the main body of innovation in functional synergistic fertilizers. , leading to a large amount of added bacteria and a low survival rate; 2) traditional microbial fertilizers use a large amount of organic matter as fillers, resulting in a large number of miscellaneous bacteria during storage, with a high rate of miscellaneous bacteria, and incomplete decomposition of microorganisms will lead to burning seedlings and rotten roots; 3) During the storage of fertilizers, the amount of microorganisms decreases rapidly, the shelf life is short, and the number of effective viable bacteria is low; 4) The vitality of the bacteria used is not strong, and it is difficult to fight against the original microorganisms in the soil and gradually die and fail; 5) The treatment of seaweed Immature process causes damage and loss of active substances
