Traditional Chinese medicinal residue fermentation composite fertilizer and preparation method thereof

Abstract

The invention relates to a traditional Chinese medicinal residue fermentation composite fertilizer and a preparation method thereof. The composite fertilizer is prepared through using the following raw materials, by weight, 1-2 parts of nitrohumic acid, 300-350 parts of traditional Chinese medicinal residue, 20-25 parts of meerschaum, 12-15 parts of vermiculite, 3-4 parts of diatomite, 10-12 parts of iron ore slag, 20-24 parts of fly ash, 20-24 parts of weathered coal, 1-2 parts of nanocarbon, 50-60 parts of bean dregs, 2-3 parts of brown sugar, 3-4 parts of bamboo charcoal, 12-14 parts of urea, 6-8 parts of potassium chloride, 10-12 parts of potassium dihydrogen phosphate, 3-4 parts of a multi-element slow release fertilizer and 1-2 parts of an EM microbial inoculums. The composite fertilizer can activate soil, increase the fertilizer efficiency and assist the release of latent nutrients in soil, allows the conversion rate of N in the soil to reach 5-10% and allows the conversion rates of P and K in the soil to respectively reach above 10%. The average yield each 666.7m<2> of crops fertilized with the composite fertilizer is 15-20% higher than that of crops fertilized with routine fertilizers under an equivalent application condition.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, in particular to fermented bio-organic and inorganic fertilizers produced from traditional Chinese medicine dregs and a preparation method thereof. Background technique [0002] my country's traditional Chinese medicine production enterprises consume 700,000 tons of herbal medicinal materials every year, and generate millions of tons of herbal medicinal residues. If not treated in time, these medicinal residues will rot, emit foul smell, and breed bacteria. Traditional methods of centralized stacking and incineration will also cause environmental pollution. Traditional Chinese medicine dregs often contain a certain amount of active ingredients and a large amount of crude fiber, crude fat, starch, crude polysaccharides, amino acids, and inorganic nutrients, and are one of the best raw materials for the production of bio-organic fertilizers. Research on the use of traditional Chinese ...
