Problems solved by technology

Mushroom chaff is the remaining waste after the production of edible fungi. The traditional method of disposal of fungus chaff is to discard or burn, which not only causes waste of resources, but also leads to the growth of mold and pests, thereby causing environmental pollution

Embodiment Construction

[0014] A humic acid microbial compound fertilizer is made from the following raw materials in parts by weight (kg):

[0015] Bacteria bran 50, humic acid 2, fruit pomace 4, peanut cake powder 4, volcanic ash 8, sepiolite powder 4, attapulgite 25, azotobacter terrestris 5, phosphate buffer solution pH7.0 70, sodium alginate 5 , calcium chloride 4, chitosan 2.

[0016] The preparation method of described humic acid microbial compound fertilizer, comprises the following steps:

[0017] (1) Puff the fungus chaff with a twin-screw extruder, cool and pulverize it, pass it through a sieve with an aperture of 0.25mm, sterilize it continuously at 121°C for 1 hour, and dry it;

[0018] (2) Mix the phosphate buffer solution with pH 7.0 and the material obtained in step (1), insert Azotobacter torus, and cultivate in a constant temperature biochemical incubator at 28°C for 7 days;

[0019] (3) Add calcium chloride and sterile distilled water to prepare a solution with a concentration of...

Abstract

The invention discloses a humic acid-microorganism composite fertilizer. The humic acid-microorganism composite fertilizer is prepared from the following raw materials in parts by weight: 50-52 parts of mushroom bran, 2-3 parts of humic acid, 4-5 parts of pomace, 4-5 parts of peanut meal, 8-9 parts of volcanic ash, 4-5 parts of sea-foam stone powder, 25-30 parts of attapulgite, 5-5.5 parts of azotobacter chroococcum, 70-72 parts of phosphate buffer solution with pH of 7.0, 5-6 parts of sodium alginate, 4-5 parts of calcium chloride and 2-3 parts of chitosan. The mushroom bran is taken as a microbial carrier, so that more organic matters are provided for strain growth; after the mushroom bran is puffed, the hydroscopicity is enhanced, and a wet living environment is provided for microorganisms; the sodium alginate is adopted for embedding, so that the salt tolerance, acid and alkali tolerance, cold and heat tolerance and drug tolerance of the microorganisms can be enhanced; the chitosan is used for enveloping, so that the defect of low mechanical strength of the sodium alginate is overcome; moreover, through the added humic acid, the soil can be improved, and the crop growth is simulated.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a humic acid microbial compound fertilizer and a preparation method thereof. Background technique [0002] With the rapid development of the world economy, the consumption of fossil fuels such as petroleum is increasing day by day. The resulting energy crisis has greatly impacted the chemical fertilizer industry, and the mass production and use of chemical fertilizers has endangered the balance of the ecological environment and human health. The microbial fertilizer has the characteristics of high fertilizer efficiency and regeneration, which is consistent with the ecological agriculture and organic agriculture advocated by modern agriculture. The microbial fertilizer carriers currently on the market include vermiculite, perlite, peat and some decomposed organic fertilizers, among which peat is the most common. Peat is formed by the gradual accumulation and peatization of pl...
