摘　　要：为保障滇西北珠子参产业健康持续的发展,2017年在珠子参大田发病高峰期,采用五点取样法对滇西北5个连片珠子参种植基地开展病害调查,统计各调查点发病株数,计算发病率和病情指数;同时观察并记录各观测点的种植模式。滇西北珠子参主要病害有3种,分别为圆斑病、黑斑病和锈病;其他病害如灰霉病、白粉病、炭疽病和疫病也有不同程度的发生。农事措施得当的观测点病害发生情况相对较低,与重楼套种或杂草滋生的观测点的发病率相对较高。圆斑病、黑斑病和锈病是珠子参生产上危害最严重的病害,可采取选择地势较高、通风效果较好、排水条件通畅的地块进行建园,设计避雨遮阴棚,可极大限度地降低珠子参病害的发生程度。The paper aims to ensure a healthy and sustainable development of Panax japonicus var. major industry in northwest Yunnan. In 2017, we investigated the diseases in 5 contiguous P. japonicus var. major planting bases during the disease peak time using a five-point sampling investigation method, counted thenumber of diseased plant, and calculated the morbidity and the disease index. There were 3 kinds of maindiseases of P. japonicus var. major in northwest Yunnan, including round spot disease, black spot and rustdisease. Other diseases also occurred in varying degrees, such as botrytis cinerea, powdery mildew,anthracnose and phytophthora blight. The incidence rate under proper farming operation was relatively lowerthan that under the intercropping with rhizoma paridis or in observation points with widespread weeds. Themost serious diseases of P. japonicus var. major production were round spot disease, black spot and rustdisease. Therefore, using proper farming operation, such as designing a shelter and building a cultivationgarden in high ground with well-ventilation and drainage condition, could greatly reduce the occurrencedegree of the diseases.
