Germination-promoting bacillus and application thereof

Abstract

The invention discloses a germination-promoting bacillus and an application thereof. The bacillus can be obtained through separating culture: taking a soil sample, employing an Ashby medium, an Alexander silicate bacteria medium, a Mengjinna organophosphorus medium, and a tricalcium phosphate inorganic phosphorus medium, and separating azotobacter, potassium bacteria, organic-phosphorus solubilizing bacteria and inorganic phosphorus solubilizing bacteria. The germination-promoting bacillus has effects for nitrogen fixation, inorganic phosphorus solubilizing, potassium releasing and inhibition of pseudostellaria root root rot fungus, can promote the growth of pseudostellaria root, increases the yield, increases the control effect of the pseudostellaria root root rot, and has promotion effect for content of a root tuber active component saponin. The influence on environment and root tuber quality for plantation of pseudostellaria root by a chemical fertilizer and pesticide cannot be reduced, production investment is not reduced, root tuber output and medicinal value are increased, and the germination-promoting bacillus is in favor of large-area plantation of pseudostellaria root in field.

Description

technical field [0001] The invention relates to a growth-promoting bacillus and application thereof, in particular to a bacillus for promoting the growth of heterophylla. [0002] technical background [0003] Pseudostellaria heterophyla is a commonly used traditional Chinese medicine, which is the dried root of Pscudostaria heterophyla (Miq.). It is a commonly used tonifying medicine in traditional Chinese medicine. It has the effects of nourishing qi and invigorating the spleen, promoting body fluid and moistening the lungs. It can be used for spleen deficiency, fatigue, weakness after illness, spontaneous sweating and thirst, and dry cough due to dryness of the lungs. After Pseudostellaria Pseudostellaria was introduced from Zherong County, Fujian Province, Shibing County, Guizhou Province has developed rapidly and has gradually become one of the economic crops for local farmers to get rid of poverty and become rich. At present, the planting area of ​​Pseudostellaria heter...

AI Technical Summary

Problems solved by technology

In response to the above problems, in order to ensure the output of heterophylla heterophylla, it is often necessary to use some chemical fertilizers (such as nitrogen, phosphorus and potassium compound fertilizers) and pesticides (such as carbendazim, kejunkang, tuendazim, guangkuling, and base thiophanate, etc.), and these chemical products will affect the quality of Pseudostellaria Pseudostellariae plantation and Pseudostellariae Pseudostellariae, thereby affecting the environment and clinical drug safety

[0004] At present, a large amount of chemical fertilizers and pesticides are used in the cultivation of Pseudostellariae Pseudostellariae, and the soil organic matter is getting poorer and poorer, which makes the continuous cropping obstacles of Pseudostellariae more obvious, such as the aggravation of diseases and insect pests, and the serious decline in yield and quality, which has caused great harm to local pesticide farmers. The economic loss has seriously affected the industrialization of Radix Pseudostellariae and the development of regional economy
