连作对白术的产量和品质有显著影响。通过对根际土壤理化性质和微生物群落的检测，探讨了水稻连作病害发生后根际土壤的变化。结果表明，病株根际土壤pH值和磷酸酶活性均高于健株。此外，42种细菌在酸杆菌门，芽单胞菌门，硝化螺菌，Elusimicrobia，和Chlorobi显示出较高的多样性，而8种放线菌门，拟杆菌门，厚壁菌门，和纤维杆菌表现出较低的多样性，在患病的。特别是在病株中，有益菌鞘氨醇杆菌属和丝孢菌属的数量减少，而病原菌如紫茎泽兰属和根瘤菌属的数量增加，可能导致再植病害。真菌中有10种多样性较低，分属子囊菌门和球囊菌门。因此，由土壤微生物群落结构变化引起的苜蓿根际微生态失衡是引起再植病害的主要原因。一些细菌如鞘氨醇杆菌和一些真菌如链格孢菌与再植病害密切相关。
Consecutive replanting significantly affects the yield and quality ofAtractylodes macrocephaladue to replant disease. To explore the changes in the rhizosphere soil when atractylodes get replant disease, we detect soil physicochemical properties and the microbial community. The results show higher level of pH and phosphatase activity in the rhizo-soil of diseased plants than that of healthy ones. Moreover, 42 species of bacteria in the phylum of Acidobacteria, Gemmatimonadetes, Nitrospirae, Elusimicrobia, and Chlorobi show higher diversity, while 8 species in the phylum of Actinobacteria, Bacteroidetes, Firmicutes, and Fibrobacteres demonstrate lower diversity in that of diseased ones. In particular, decreased numbers of some beneficial bacteria includingSphingobium and Hyphomicrobiumwhile increased numbers of pathogens such asAsticcacaulis, Rhizomicrobiumin diseased ones may lead to replant disease. For fungi, there are 10 species with lower diversity in diseased ones, which belong to Ascomycota and Glomeromycota. In conclusion, microecological imbalance in Atractylodes rhizosphere caused by variation of the soil microbial community is considered the primary cause of replant disease. Some bacteria such asSphingobiumand some fungi includingAlternaria alternateare closely related to the replant disease.
