Embodiment

[0040] 1. Isolation of Bacillus megaterium M1

[0041] Evenly mix 5-10g of commercially available enzyme bacteria with 5-10g of nutrient-based cornstarch, 5-10g of brown sugar and 10-20g of wheat bran, pH6.0-7.0, humidity control at 30-35%, and then add hydroxylamine or ethyl alcohol The imine is 0.005-0.05g, the temperature is 25-35°C, and the temperature difference is 8-10°C. After 2-3 days of cultivation, the Bacillus megaterium M1 is screened out with an inoculation loop. The nutrient base may also include at least one of 3-5 g of fish meal, 3-5 g of vegetable cake and 35-50 g of polished rice bran.

[0042] 2. Cultivation of Bacillus megaterium M1

[0043] Bacillus megaterium M1 grows on the following media:

[0044] Sucrose 50g (NH 4 ) 2 SO 4 6g NgSO 4 2.5g (NH 4 ) 3 SO 4 2g

[0045] K 2 SO 4 2.5g CaSO 4 2.5g agar 1520g distilled water 1000ml pH6.0

Abstract

The invention discloses a biological fertilizer, comprising the following components and content (part by weight): 1 to 2 parts of enzyme microorganism; 20 to 40 parts of sludge; 20 to 40 parts of Artemisia slag; 10 to 20 parts of rice bran powder; 5 to 10 parts of peat; 10 to 30 parts of smoke powder. The enzyme microorganism comprises a huge bacillus M1 which is preserved by CGMCC (Bac.megatherium.M1) and the preservation number of which is NO.2267. The biological fertilizer which operates the compatibility of the enzyme microorganism with the sludge and wastes uses the characteristics that the enzyme microorganism is high in sludge treating ability and strong in compatibility of the fertilizer, pesticides and the wastes fully, thus realizing the changing of waste to valuable and providing optional organic fertilizers for agriculture and forestry production. The biological fertilizer also discloses a preparation method of the biological fertilizer.

Description

technical field [0001] The invention relates to a biological fertilizer, in particular to a biological fertilizer containing enzyme bacteria and a preparation process thereof. Background technique [0002] Sludge is a potential resource with great utilization value. Many countries in the world are vigorously developing various technologies for sludge treatment, disposal and utilization. Due to the shortcomings of other sludge treatment and disposal technologies, the most commonly used sludge treatment method is to compost the dewatered sludge. After the composting process, the sludge can be stabilized and harmless. Sewage sludge contains a large amount of organic matter, nitrogen, phosphorus and other plant nutrients. The organic matter content reaches 20-80%, the total nitrogen content reaches 2-8%, and the total phosphorus (P 2 o 5 ) content of 1.5 to 5%, is a special high-efficiency fertilizer. From the point of view of natural circulation, the final destination of slu...
