Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with specific embodiments.

[0016] The microbial bacteria with acid production function of the present invention is to kill non-bacillus by adopting 80°C treatment, and cultivate (1L) with improved MRS: peptone 10g, beef extract 10g, yeast extract 5g, diammonium hydrogen citrate 2.0g, glucose 20g, dipotassium hydrogen phosphate 2g, ammonium sulfate 1.63g, sodium acetate 5g, magnesium sulfate 0.58g, manganese sulfate 0.25g, Tween 80mL, calcium carbonate 1g, agar 18g, add distilled water to 1000mL, pH 6.4±0.2, respectively in Cultivated under anaerobic and aerobic conditions. Eight acid-producing Bacillus strains were isolated and purified from maize plants grown on poor soil in Guangzhou. The fermentation acid production ability of 8 strains was further screened, and the strain WSA061 with fast growth rate, strong acid production ability, and acid production under different medium formulatio...

Abstract

The invention discloses a microbial bacterium with an acid-producing function and an organic fertilizer applied thereto. The bacterial strain can produce acid under different fermentation conditions. Compared with inorganic salts, the acid production lasts for a long time, does not need to be frequently applied, and does not appear At the same time, it can optimize the micro-ecological environment for root growth of alkaline soil crops; the strain is derived from corn rhizosphere soil in barren soil, which can significantly promote the growth of lettuce, corn and other crops on alkaline soil. Tolerance, improve soil urine enzyme activity, and provide an excellent liquid bacterial fertilizer for the growth of lettuce, corn and other crops in alkaline soil; the organic fertilizer prepared by the strain can significantly improve the leaves of lettuce, corn and other crops. The chlorophyll content of the tissue, the Vc content of the leaves, and the yield have a good effect of increasing the quality and increasing the yield.

Description

technical field [0001] The invention relates to a microbial bacterium, in particular to a bacillus amyloliquefaciens capable of fermenting acid production, alkali resistance and antibiotics, and the organic fertilizer produced therefrom and its application. Background technique [0002] Bacillus amyloliquefaciens is a bacterium with a high affinity with Bacillus subtilis, which can produce a series of metabolites during its own growth, which enable Bacillus amyloliquefaciens to have a wide range of inhibitory fungi and bacteria active. Therefore, in recent years, a large number of scholars have done a lot of exploration on the new discovery and application of Bacillus amyloliquefaciens, gene function research and optimization of fermentation conditions. Bacillus amyloliquefaciens can produce a variety of antibacterial substances, with a wide bactericidal spectrum, and has a preventive effect on pathogenic bacteria. Therefore, it has a very significant effect on preventing a...
