Embodiment 1

[0035] A biological humic acid fertilizer, prepared from the following raw materials in parts by weight: 200 parts of straw fermented humic acid, 50 parts of urea, 40 parts of monoammonium phosphate, 50 parts of potassium sulfate, 50 parts of bentonite, 20 parts of medium elements, trace elements 10 parts of elements, 10 parts of biological agents, 5 parts of polyglutamic acid.

[0036]The preparation method of the stalk fermented humic acid is as follows: dry the corn stalks and pulverize them, add 0.1wt% Trichoderma viride and 0.1wt% Bacillus thuringiensis, adjust the water content to 50%, aerobically or Facultatively ferment for 8 days, and dry the water to obtain straw fermented humic acid.

[0037] The Trichoderma viride and Bacillus thuringiensis can be commercially available bacteria powder.

[0038] The bentonite is pretreated bentonite, and the pretreatment method is as follows: put the bentonite in a heating furnace, calcinate for 9 minutes at 500° C. under anaerobi...

Abstract

The invention discloses a biological humic acid fertilizer and a preparation method thereof, and belongs to the technical field of microbial fermentation. Corn straw is used as a raw material to prepare biological humic acid, trichoderma viride and bacillus thuringiensis are used for mixed fermentation, pretreated bentonite is used as a humic acid carrier, Bacillus algicola is used as an auxiliary microbial agent, and a small amount of necessary NPK and medium trace elements are added as nutritional supplements, so supplementary application of inorganic fertilizers is avoided, interaction and synergistic cooperation of the raw materials is achieved, the problems of unstable fertilizer efficiency and short action time of biological humic acid are fundamentally solved, the ecological environment of soil can be effectively regulated,the activity of soil is improved, and the biological humic acid fertilizer is harmless to the environment after long-term use, and has potential economic value and social value.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation, and in particular relates to a biological humic acid fertilizer and a preparation method thereof. Background technique [0002] In field production, fertilization is the most important factor for increasing crop yield, and it contributes significantly to crop yield and plays an irreplaceable role. Ordinary fertilizers, such as urea and conventional compound fertilizers, are used in large quantities, which, while costing a lot, also lead to serious degradation of soil quality and bring great harm to the environment. A number of studies have shown that long-term application of conventional chemical fertilizers will lead to changes in the physical and chemical properties of crop rhizosphere soil, reduce soil enzyme activity, kill a large number of beneficial microorganisms, and change the structure of soil microbial communities. Therefore, agricultural production urgently needs to ad...
