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 microelement liquid water-soluble fertilizer through alga composite graded fermentation. Dried algae are ground into powder, and the alga powder is put into a fermentation tank to be sterilized; seed solutions of two strains are prepared and inoculated into an alga base material multiple times, and graded fermentation is achieved; an alga solution is obtained through filter pressing after fermentation, the alga solution and microelements are added into a stirring kettle in proportion, stirred and thoroughly dissolved, and the microelement liquid water-soluble fertilizer containing the alga solution is obtained. The technical effect of the composite graded fermentation technology is obviously better than that of single strain fermentation and that of common multi-strain mixed fermentation; besides, the fermentation efficiency is high, time is short, and the whole process is high in operability, environmentally friendly and capable of saving energy. Microelements and effective ingredients of algae are combined in the product, and the product has remarkable effects on the aspects of improving the stress resistance and the disease resistance of crops, and can meet the demands of modern agriculture.

Description

technical field [0001] The invention relates to a production method of trace 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 Ascop...
