苍术根腐病及其防治研究进展

苍术根腐病是当前苍术人工种植过程中最严重的一种病害，严重影响苍术产业的发展。苍术根腐病表现为地上部分叶片萎蔫，根及根茎变褐腐烂，导致苍术大面积死亡，产量下降。基于国内外报道，本文阐述了苍术根腐病的病原、病症和病因，及其物理、化学和生物防治等措施，并对目前苍术根腐病在田间生产防治中存在的主要问题进行讨论，旨在为苍术的实际生产和根腐病防治提供参考。

Research progress and control of root rot in Atractylodes lancea

Root rot of Atractylodes lancea is one of the most serious diseases currently affecting artificial planting of A.lancea and seriously affects the commercial development of this plant.Root rot of A.lancea is characterized by leaf wilting on the aerial part and browning and rot of roots and rhizomes, which lead to large-scale plant death and decreased yield. Based on reports from China and abroad, the pathogen, disease, and etiology of root rot of A.lancea were described, together with the physical, chemical, and biological control measures, the main problems existing in the control of A.lancea root rot in field production were discussed. This review provides a reference for the production of A.lancea and for the prevention and control of root rot.
