Microbial organic fertilizer capable of improving acidity of soil

Abstract

The invention discloses a microbial organic fertilizer capable of improving acidity of soil. Strains contained in the organic fertilizer disclosed by the invention can produce acid under different fermentation conditions, so that compared with inorganic salts, the organic fertilizer has the advantages that acid production is lasting, frequent applying is not required, the problems of soil caking and the like caused by anion enrichment do not occur, and meanwhile, a micro-ecological environment for root growth of alkaline soil crops can be optimized; the strain are derived from poor soil, i.e., corn rhizosphere soil, so that the tolerance of crops such as lactuca sativa, corn and the like to alkaline soil can be obviously promoted, the activity of urease of the soil can be improved, and an excellent liquid bacterial fertilizer can be provided for the growth of the crops such as lactuca sativa, corn and the like in the alkaline soil; and the organic fertilizer prepared from the strains can be used for obviously increasing the chlorophyll content of leaf tissue of the crops such as lactuca sativa, corn and the like, the Vc content of leaves of the crops such as lactuca sativa, corn and the like and the yield of the crops such as lactuca sativa, corn and the like, thereby having the good effect of improving quality and increasing yield.

Description

technical field [0001] The invention relates to a bio-organic fertilizer, in particular to a microbial organic fertilizer capable of improving soil acidity. 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 and controlling diseases of crops, vegetables, and melons and fruits. The market development prospect ...

AI Technical Summary

Problems solved by technology

However, the suitable growth environment for Bacillus amyloliquefaciens is a high-protein culture solution and an environment with a pH value of 3 to 5. It grows slowly in alkaline soil, so it needs to be expanded to a certain number in advance and provide enough protein environment to be able to grow. improve its effect
