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 high-nutrient microbial fertilizer is made from the following raw materials in parts by weight (kg):

[0015] Bacteria bran 50, traditional Chinese medicine residue 5, soybean meal 6, sphagnum moss 4, sugar residue 5, caragana powder 5, attapulgite 25, Azotobacter terrestris 5, pH7.0 phosphate buffer 70, sodium alginate 5 , calcium chloride 4, chitosan 2.

[0016] The preparation method of described high-nutrient microbial bacteria 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...

Abstract

The invention discloses a high-nutrient microbial fertilizer. The high-nutrient microbial fertilizer is prepared from, by weight, 50 to 52 parts of mushroom bran, 5 to 6 parts of traditional Chinese medicinal material residue, 6 to 7 parts of soya bean meal, 4 to 5 parts of herba sphagni, 5 to 6 parts of sugar residue, 5 to 6 parts of caragana korshinskii powder, 25 to 30 parts of attapulgite, 5 to 5.5 parts of azotobacter chroococcum, 70 to 72 parts of a phosphate buffer with a pH value of 7.0, 5 to 6 parts of sodium alginate, 4 to 5 parts of calcium chloride, and 2 to 3 parts of chitosan. According to the invention, mushroom bran is taken as a microorganism carrier, and more organic matters are provided for growth of bacteria; water absorbing quality is improved via puffing of mushroom bran, and a moist living environment is provided for microorganisms; embedding with sodium alginate is capable of improving salt tolerance, acid and alkali resistance, cold and hot resistance, and drug resistance of microorganisms; and a problem that the mechanical strength of sodium alginate is poor is solved via coating with chitosan; and the high-nutrient microbial fertilizer is high in nutrient content, and is capable of increasing crop yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-nutrient microbial 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 plant re...
