[0017] The preparation process of example 1 bacterial liquid

[0018] (1) The cultivation process of Bacillus amyloliquefaciens

[0019] Primary test tube slant culture: NYDA medium: beef extract 8g, peptone 8g, glucose 10g, agar 15g, distilled water 1000mL. Bacillus amyloliquefaciens was inoculated on the test tube NYDA medium, activated and cultured at 28°C for 24 hours to obtain the test tube strain.

[0020] Secondary seed culture: NYD medium: beef extract 8g, peptone 8g, glucose 10g, distilled water 1000mL. Put the above-mentioned strains in the test tube into the NYD culture medium, culture on a shaker for 24 hours (28°C, 130 rpm) to make the first-grade seed solution, and then inoculate the first-grade seed solution in 100mL NYD culture medium at a ratio of 1:100 Carry out fermentation culture (28°C, 130 rpm) for 24 hours to obtain secondary seed liquid.

Abstract

The invention belongs to the technical field of fertilizer preparation, and particularly relates to a biological compound organic bacterial fertilizer which is composed of a compound fertilizer and a mixed microbial agent. The compound fertilizer comprises the following raw fertilizers in percentage by weight: 14.5% to 25.2% of humic acid, 33.5% to 45.1% of biochar, 22.5% to 35.5% of chemical fertilizer and 10.2% to 15.4% of bentonite; besides 10 mL to 20 mL mixed microbial agent is added into the compound fertilizer per kilogram. The biological compound organic bacterial fertilizer not only can be taken as an auxiliary fertilizer to be mixed with a chemical fertilizer for use, but also can be used alone, can effectively supply soil organic matters, activates P fertilizer and K fertilizer of soil, and improves the disease resistance of crops; particularly, the microbial agent is composited, so that the biological compound organic bacterial fertilizer has a better effect on the prevention and treatment of soil-borne disease and continuous cropping disease of the crops, and is efficient, nontoxic and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a biological compound organic bacterial fertilizer. Background technique [0002] At present, the most prominent problems in the process of agricultural production mainly include: soil compaction caused by large-scale application of chemical pesticides; unreasonable use of crop straw, environmental pollution and safety hazards caused by in-situ burning; residues caused by the use of chemical pesticides; The problem of repeated cropping of diseases; the waste of labor caused by separate fertilization and pesticides. These problems pose serious obstacles to agricultural production and crop yield enhancement. With the application of microbial technology in agriculture, many functional bacteria are also widely used in the fields of pesticides and fertilizers, which provide effective methods and solutions for the realization of environmental protection, poll...
