Embodiment Construction

[0019] The invention adopts Bacillus subtilis, whose strain code is 1.1413; adopts Bacillus licheniformis, whose strain code is 1.813; The above strains are preserved in the China General Microorganism Culture Collection and Management Center.

[0020] Proportion of strains: Bacillus subtilis 40%, Bacillus licheniformis 30%, Bacillus stearothermophilus 30%.

[0021] According to the above method, the microbial composite bacterial agent is made, and the pH value is 6.8 after testing, and the bacterial count reaches 8×10 9 pieces / ml.

[0022] A. The composite bacterial agent prepared according to the present invention can be made into wettable powder—microbial starter after adsorption, pressure filtration, crushing, and drying. Wherein the adsorbent adopts light calcium carbonate, and the weight ratio of the composite bacterial agent to the adsorbent is 70:30. The fineness of the prepared microbial starter is 0.15-0.20mm.

Abstract

A composite microbial preparation is prepared from hay bacillus (35-45%) lichen bacillus (25-35%) and thermofat bacillus (25-35%) through inclulating, culturing, proportional mixing, and culturing again. A microbial leaven is prepared from said composite microbial preparation through adsorption, press filter, breaking and baking. A microbial fertilizer is prepared from said composite microbial preparation, mud, peet, dung and dropping of chicken and livestock, distiller's grain, powered coal ash, straw or stalk, and city refuse through fermenting.

Description

(1) Technical field [0001] The invention belongs to the field of biological materials, and in particular relates to a microbial composite bacterial agent and a microbial fermentation agent and fertilizer made from the same. (2) Background technology [0002] Due to the advantages of convenient use and fast fertilizer effect, chemical fertilizers have a significant effect on increasing agricultural production, resulting in a wider range of application of chemical fertilizers and an increasing amount. However, long-term large-scale application of chemical fertilizers, pesticides, herbicides and other chemical substances and continuous cropping can easily cause soil compaction, sharply reduce beneficial microorganisms in the soil, reduce soil permeability, oxygen supply capacity and maintain nutrient balance, and a large number of harmful substances. Harmful microorganisms control the absorption of nutrients and water by plant roots, change the soil structure, lead to poor grow...
