Method for preparing traditional Chinese medicine microbial fertilizer of spinach

Abstract

The invention discloses a method for preparing a traditional Chinese medicine microbial fertilizer of spinach. The method specifically comprises the steps as follows: fermented cultivation of microorganism, processing of crop straws, addition of poultry excrement and wastes of a slaughter house, fermentation treatment, dissolution of an additive, mixing, drying, smashing, canning for obtaining a finished product and the like. The microbial fertilizer prepared by the invention enables yield of spinach, content of vitamin C and iron element to be increased and enables content of nitrate to be decreased, so that the spinach quality is improved greatly; and the microbial fertilizer has functions of insecticide, bactericide and weed control, is pollution-free and no-residue and has better economic and social benefits.

Description

technical field [0001] The invention relates to a preparation method of microbial fertilizer, in particular to a preparation method of spinach traditional Chinese medicine microbial fertilizer, belonging to the field of fertilizers. Background technique [0002] Spinach is one of the vegetables that people often eat. It has the effect of supplementing iron and is deeply loved by people. At present, with the improvement of spinach cultivation technology and the increase in the amount of agrochemical products, the yield of spinach has also been greatly increased, but at the same time it has also produced side effects, such as quality decline, poor taste, and increased pollution. People are more interested in organic spinach. The popularity is also increasing. However, the output of organic vegetables is not high, which cannot meet people's needs. The specific reason is that the nutrient content of organic fertilizer is unstable, and the ratio of main nutrient elements is unr...

AI Technical Summary

Problems solved by technology

At present, with the improvement of spinach cultivation technology and the increase in the amount of agrochemical products, the yield of spinach has also been greatly increased, but at the same time it has also produced side effects, such as quality decline, poor taste, and increased pollution. People are more interested in organic spinach. more and more favored

However, the output of organic vegetables is not high enough to meet people's needs

The specific reason is that the nutrient content of organic fertilizer is unstable, and the ratio of main nutrient elements is unreasonable, resulting in a significant decrease in the yield of organic vegetables

Second, some organic fertilizers contain harmful substances. For example, organic fertilizers produced with animal manure as the main raw material contain feed additive residues, and organic fertilizers produced with biochemical sludge from sewage treatment plants as the main raw material contain heavy metals. Spinach is completely operated in accordance with the production standards of organic agricultural products, and the safety of its products is difficult to guarantee

This needs to change the existing organic fertilizer production mode, so that the nutrient release in the organic fertilizer meets the nutrient absorption requirements of spinach. At present, the research on spinach traditional Chinese medicine microbial organic fertilizer is still rare.
