Example Embodiment

[0014] A microbial fertilizer for activating soil fertility is made from the following raw materials in parts by weight (kg):

[0015] Bacteria bran 50, peanut seedling 6, sepiolite powder 5, peat soil 10, fish meal 5, attapulgite soil 25, Azotobacter terrestris 5, pH7.0 phosphate buffer 70, sodium alginate 5, calcium chloride 4 , Chitosan 2.

[0016] The preparation method of the microbial fertilizer of described activation soil fertility, 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 4%...

Abstract

The invention discloses a microbial fertilizer for activating soil fertility. The microbial fertilizer is prepared from the following raw materials (by weight): 50-52 parts of fungus chaff, 6-7 parts of peanut vine, 5-6 parts of meerschaum powder, 10-11 parts of turfy soil, 5-6 parts of fish meal, 25-30 parts of attapulgite, 5-5.5 parts of azotobacter chroococcum, 70-72 parts of a phosphate buffer with pH7.0, 5-6 parts of sodium alginate, 4-5 parts of calcium chloride and 2-3 parts of chitosan. According to the application, fungus chaff is used as a microbial carrier, and more organic matters are provided for growth of strains. After fungus chaff is puffed, water absorption of the microbial fertilizer is raised, and a moist living environment is provided for microbes. By embedding of sodium alginate, salt tolerance, acid-base resistance, cold and heat resistance and drug resistance of microbes can be enhanced. By coating with chitosan, low mechanical strength of sodium alginate is overcome. In addition, the added turfy soil and the like can improve soil and activate soil fertility.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial fertilizer for activating soil fertility 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 peatiza...
