In purplish soil, the number of dominant microbial populations in the rhizosphere was greater than in the other two soils, and the population diversities of bacteria and actinomycetes were even greater and more constant, suggesting that the community structures of microorganisms in neutral purplish soil were more reasonable than in both yellow earth and yellow rendzina, which was probably related to the low incidence of tobacco bacterial wilt in the neutral purplish soil.

烤烟根际微生物的种群多样性及其变化在不同土壤中表现也不一样，相对于黄壤和黄色石灰土，在中性紫色土中，根际微生物的优势种群数目较多，根际细菌和放线菌种群更具多样性，而且较稳定，表明其群落结构更为合理，这可能与中性紫色土上的烟草青枯病发生率较低有一定关系。
