Influence to American ginsen plantation under dynamics of rhizospheric soil microbes
Dynamics of rhizospheric soil microbes on American ginsen and maize rotation from Shannxi production area was studied by animalcule separation, count and identification. Bacteria of dissolving phosphorus, potassium and bacterium of fixing nitrogen were also researched. The results showed that there existed no differences on the amount of bacterium, but the categories of bacterium decreased with the growing of ginsen comparing to the maize rotation; the amount and categories of actinomyces both reduced. However, the mould which caused the ginsen's diseases increased. It was also found that the content of phosphate and potassium solubilizing bacteria and Azotobacter apparent disordered. The physical and chemical of soil changes with the variation of the soil microbial community structure, which affected the continue cultivation of ginsen, provided the theoretical basis for the further development of ginsen.
