Humic acid organic compound bacterial fertilizer and preparation method thereof

Abstract

The present invention relates to a humic acid organic compound bacterial fertilizer and a preparation method thereof, wherein the humic acid organic compound bacterial fertilizer comprises, by weight, 110-200 parts of plant straws, 30-50 parts of manure, 8-20 parts of oil residue, 4-8 parts of pure humic acid, 1-4 parts of trace elements, 7-12 parts of bran, 1-3 parts of brown sugar, 3 parts of bacteria, and 750-1300 parts of water. The preparation method comprises: crushing straws, fermenting the crushed straws and manure according to a certain ratio, adding oil residue and pure humic acid to the fermented biogas residue, uniformly stirring, carrying out natural air drying, carrying out ball mill crushing after the air drying, adding an auxiliary material, continuously fermenting, adding trace elements and bacterial after 10 days to form a slurry juice, adding water, carrying out stirring dilution, filtering, carrying out qualification testing on the filtered liquid fertilizer, bottling, compounding the filtered residue and the bacteria, granulating, drying, screening, carrying out qualification testing, and bagging. According to the present invention, the contents of nitrogen, phosphorus and potassium are formed during the extraction on the crop straws, the content of the organic matter is formed through the extraction from the humic acid and various manures, the microbial fertilizer is not added with the chemical components, the straws are rich in a variety of nutrition elements absorbed by crops, and the product is the pollution-free and residue-free green environmental protection product.

Description

technical field [0001] The invention relates to a fertilizer for crops, in particular to a humic acid organic compound bacterial fertilizer and a preparation method thereof. Background technique [0002] The use of livestock and poultry manure to process organic fertilizer has a long history in my country. However, due to the thin and smelly livestock and poultry manure, it is inconvenient to store, transport, process and utilize, the labor intensity is high, and the working conditions are dirty. In recent years, fewer and fewer farmers collect and compost manure to process organic fertilizer, and the amount of organic fertilizer input per mu decreases year by year. A large amount of manure is discharged, which not only causes waste of resources, but also pollutes the environment and limits the sustainable development of agriculture. According to my country's agricultural development is inseparable from fertilizers. In order to improve the soil, scientific straw returning to...

In fact, urea itself is a kind of chemical substance, which will make the soil harden, destroy the aggregate structure of the soil and the new metabolism of the soil, so the addition of urea can prevent the root system of crops from growing, and can not achieve photosynthesis, which will affect the increase in production and income and the growth of crops. quality
