AI Technical Summary

Technical Problem

Plant growth is inhibited in saline-alkali soil. Existing technologies are difficult to effectively reduce soil salt content and enhance microbial activity. Traditional biological improvement methods are complex and uneconomical.

Method used

Acidic bentonite and sea clam shell powder are formulated at a ratio of 6:1, combined with calcium propionate, spirulina powder, dried cow dung, sawdust and food residue fermentation, phosphate-solubilizing bacteria and superphosphate, to prepare organic fertilizer through fermentation, and neutralize Soil cations and maintain soil structure, enhance microbial activity.

Benefits of technology

It can reduce soil salt content, enhance soil microbial activity, promote plant root growth, and improve saline-alkali soil conditions. The method is simple, the product ratio is simple, and it is easy to use.

Abstract

The invention discloses a method for preparing an organic fertilizer for enhancing the activity of microorganisms of soil. The method comprises the following steps: (A) preparing materials: preparing a mixture, which is prepared from acidic bentonite and sea clam shell powder according to the mass ratio of 6: 1, calcium propionate, spirulina powder, dry cattle manure, a mixture, which is prepared from wood sawdust and a food residue fermented product according to the mass ratio of 1: 5, phosphate solubilizing bacteria, calcium superphosphate and zymocyte; (B) crushing calcium propionate and spirulina powder, then, mixing with the mixture, which is prepared from the wood sawdust and the food residue fermented product according to the mass ratio of 1: 5, then, uniformly stirring with the dry cattle manure, and adding the zymocyte during stirring; (C) mixing the mixture, which is prepared from acidic bentonite and the sea clam shell powder according to the mass ratio of 6: 1, into the fermented product obtained in the step (B), then, adding phosphate solubilizing bacteria and calcium superphosphate, watering until the moisture content is 63-65%, and preparing rods with an extrusion machine. The method disclosed by the invention is simple, and the prepared product is simple in proportioning and convenient in use and can be used for lowering the salt content of the soil, enhancing the activity of microorganisms and enzymes in the soil and promoting the growth of plant roots.
