Embodiment 1

[0022] Trichoderma (preservation number: CGMCC No.10928, the same below) was inoculated into the seed tank and fermented for 24 hours according to the conventional method, and then transplanted to the thalline fermentation liquid obtained after 24 hours of fermentation in the fermenter. The thalline fermentation liquid contained dried mycelium The weight is 2.5g / L, reserve.

[0023] Take 600kg of ammonified lignite, 30kg of wheat bran, 30kg of soybean meal powder, and 250kg of mushroom sticks, mix them evenly and add them to the fermentation tank after crushing, dissolve 10kg of urea + 10kg of potassium dihydrogen phosphate in 500kg of water, and then add 50kg of the above prepared Stir the Trichoderma culture solution evenly, mix it into the raw materials of the fermentation tank, and ferment it at 20-30°C for 10 days. The measured water-soluble humic acid content is 22.3%, and the water-soluble humic acid content before fermentation is 4.6%. Humic acid content increased by 4...

Embodiment 2

[0025] Trichoderma was inoculated into the seed tank and fermented for 36 hours according to the conventional method, and then transplanted to the thalline fermentation liquid obtained after 48 hours of fermentation in the fermenter. The thalline fermentation liquid contained mycelium dry weight and was 3.0g / L for subsequent use.

[0026] Take 700kg of sodium humate, 50kg of wheat bran, 50kg of soybean meal powder, and 300kg of corn stalks, mix them evenly and put them into the fermentation tank, dissolve 10kg of urea + 20kg of potassium dihydrogen phosphate in 600kg of water, and then add 80kg of the above-prepared wood Stir the mold culture solution evenly and mix it into the raw materials of the fermentation tank, ferment at 20-30°C for 15 days, the measured water-soluble humic acid content is 29.1%, the water-soluble humic acid content before fermentation is 6.5%, and the water-soluble humic acid content after fermentation The acid content increased by 4.48 times.

Embodiment 3

[0028] Trichoderma was inoculated into the seed tank and fermented for 24 hours according to the conventional method, and then transplanted to the thalline fermentation broth obtained after 36 hours of fermentation in the fermenter. The thalline fermentation fluid contained mycelium dry weight and was 2.7g / L for subsequent use.

[0029] Take 650kg of weathered coal, 50kg of wheat bran, 30kg of soybean meal powder, and 200kg of sawdust and mix them into the fermentation tank after crushing. Dissolve 15kg of urea + 15kg of potassium dihydrogen phosphate in 550kg of water and add 60kg of Trichoderma prepared above for cultivation. Stir the solution evenly and mix it into the raw materials in the fermentation tank, ferment at 20-30°C for 15 days, and measure the content of water-soluble humic acid to be 13.6%, the content of water-soluble humic acid before fermentation is 2.3%, and the content of water-soluble humic acid after fermentation Increased by 5.91 times.

Abstract

The invention claims to protect a method for increasing the content of water-soluble humic acid in a humic acid matrix. Adopted trichoderma is (trichoderma sp.HZD-1) preserved in China General Microbiological Culture Collection Center (CGMCC) in June 1, 2015 with a preservation number of CGMCC No.10928. compared with the prior art, the method has the advantages that the production method is simple, the biological activity of the product is high, the content of water-soluble humic acid in the humic acid matrix can be effectively increased, the biological activity and utilization rate of the water-soluble humic acid are increased, and the chemical residue and the secondary pollution are avoided.

Description

technical field [0001] The invention belongs to the technical field of agricultural microbial fertilizers, in particular to a method for increasing the content of water-soluble humic acid in a humic acid matrix. Background technique [0002] Humic acid widely exists in sediments such as soil, water and coal, and is a kind of organic substance formed by animal and plant residues (mainly plant residues) through complex chemical, biological decomposition and synthesis reactions with the participation of microorganisms. Humic acid has a very important impact on the carbon cycle in nature, the distribution and transformation of organic and inorganic compounds, and soil fertility. It has been widely used in industry, agriculture, animal husbandry, and medicine. In terms of agricultural applications, humic acid substances, as the main component of soil organic matter, are the main provider of plant nutrients, which can promote plant growth, promote root development, improve root ac...
