Rich-in-selenium liquid bacterial manure, preparation method and application

Abstract

The invention provides rich-in-selenium liquid bacterial manure, a preparation method and application, and belongs to the technical field of agricultural biology. The raw materials of the rich-in-selenium liquid bacterial manure comprise biogas slurry, mushroom slag, EM bacteria solution, EM raw bacteria solution, CM bacteria, selenite and brown sugar. The rich-selenium liquid bacterial manure can provide various nutrition elements for vegetables for promoting the growth. The preparation method of the rich-in-selenium liquid bacterial manure comprises the following steps of adding partial EM bacteria solution, mushroom slag and partial CM bacteria solution into the biogas slurry; regulating the pH value; performing primary fermentation to obtain first fermentation solution; mixing the rest EM bacteria solution and the partial selenite solution with the first fermentation liquid; after 4 to 6 days, adding partial EM raw bacteria solution, the rest CM bacteria solution and the rest selenite solution; performing secondary fermentation to obtain the rich-in-selenium liquid bacterial manure. The preparation method has the advantages that the technology is simple; the selenium liquid bacterial manure with the excellent performance can be effectively prepared. The preparation method of the rich-in-selenium liquid bacterial manure can be applied to leaf fertilizers or root irrigation fertilizers.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a selenium-enriched liquid fertilizer and its preparation method and application. Background technique [0002] With the continuous development of the economy and the continuous progress of the society, people gradually begin to have higher and higher requirements for the quality of life; they also pay more and more attention to food safety. [0003] At present, organic ingredients are becoming more and more sought after by everyone, and a large amount of organic fertilizer is needed in the process of planting organic ingredients; however, farm organic fertilizer degrades slowly and has low utilization efficiency, which is not conducive to large-scale production and use; the general bacterial fertilizer fermentation cycle Long, which limits the large-scale and rapid production of bacterial fertilizer, which is not conducive to production and application.
