Microbial organic fertilizer for improving soil that has been used for planting multi-batch vegetable and fruit and preparation method thereof

Abstract

The invention discloses a microbial organic fertilizer for improving the soil that has been used for planting multi-batch vegetable and fruit and a preparation method thereof. The microbial organic fertilizer is prepared by mixing a specially-made microbial composite inoculant, manure, and edible fungus residues according to a certain ratio and then subjecting the mixture to aerobic fermentation. The microbial chelating agent is prepared by mixing microbial floras, a culture liquid, and a heavy metal passivating material according to a weight ratio of 1:7:12. Through an aerobic composting technology, and the cooperative effect between microorganisms and a heavy metal passivating material, accumulated heavy metals in soil and manure are efficiently passivated, the output of fruit and vegetable is prominently increased, the labor cost is reduced, the harmless treatment of livestock and cattle manure compost is realized, and a high quality composite microbial organic fertilizer is provided.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a microbial organic fertilizer used for soil improvement of multi-crop vegetables and fruits and a preparation method thereof. Background technique [0002] Vegetables and fruits are rich in vitamins and minerals, especially multi-crop fruits and vegetables (cucumbers, tomatoes, peppers...) are easier to meet people's daily needs and are as indispensable as food. The economic benefits of fruits and vegetables depend on the difference between their input and output and the output of the year. Providing high-yield and high-quality fruits and vegetables is what growers are after. [0003] In recent years, the annual growth rate of my country's livestock and poultry breeding industry has reached more than 10%. Among them, the number and scale of pig breeding ranks first in the world, and the number of livestock and poultry breeding such as chickens, ducks, and cattle also ranks ...

AI Technical Summary

Problems solved by technology

[0004] A large number of research results have shown that poultry manure contains high levels of heavy metal elements such as lead, copper, mercury, arsenic, chromium, and cadmium. The organic fertilizer obtained after the manure is decomposed is used for agricultural planting for a long time, and it will slowly dissolve in the soil. Accumulate and be absorbed by plants, and long-term use will pose a threat to the quality and safety of soil, groundwater and agricultural products

In addition, the composting process will produce odors containing chemical substances such as sulfides, amines, and lower fatty acids. Long-term exposure can easily cause respiratory infections in humans and livestock, and gases such as hydrogen sulfide, ammonia, and mercaptans are emitted into the atmosphere. more likely to cause acid rain
