Problems solved by technology

[0007] Due to the severe compaction and acidification of the soil and the erratic changes in the outside temperature, the microbial agents cultivated in the greenhouse are directly put into the soil, causing a large number of deaths because they cannot adapt to the harsh soil environment. The effect of the agent

Abstract

The invention relates to a method for preparing medium element liquid water-soluble fertilizer by seaweed combined hierarchical fermentation; dried seaweed is ground into powder that is loaded in a fermentation pot for sterilizing; seed liquids of two bacteria are prepared respectively, the seed liquids are inoculated to seaweed stock in multiple phases such that hierarchical fermentation is achieved; after fermentation, seaweed liquid is obtained by press filtering, and the seaweed liquid and medium elements are proportionally added into a stirring kettle and are stirred and fully dissolved to obtain the medium element liquid water-soluble fertilizer with seaweed liquid; the combined hierarchical fermentation technique used herein is more effective than single bacterium fermentation and common multi-bacterium mixed fermentation, with high fermentation efficiency and low time consumption; the whole process is highly operable, green and energy-saving, and is environment-friendly; the fertilizer combines medium elements with the effective ingredients of seaweed, and the fertilizer is significantly effective in improving stress tolerance and disease resistance in crops and can meet the needs of modern agriculture.

Description

technical field [0001] The invention relates to a production method of medium element liquid water-soluble fertilizer. Background technique [0002] Seaweed fertilizer is a new type of organic fertilizer that uses natural seaweed as raw material, undergoes special biochemical processing, extracts and retains the natural active ingredients of seaweed, refines and concentrates. Seaweed fertilizer has the effect of improving crop yield and quality, resisting pests and diseases and adverse environment, and improving soil and water conservation. Its application in agricultural production has huge market demand and good development prospects. However, in order to ensure the quality of seaweed fertilizer, two key links of seaweed raw material and extraction process must be grasped. [0003] First of all, the quality of seaweed fertilizer depends on the raw materials used. At present, the raw materials used by seaweed fertilizer manufacturers are mainly brown algae, including Asco...
