贝母属百合科植物,为常用中药。药用部分为地下鳞茎。由于鳞片水多质嫩,地下害虫喜吃,病菌容易侵染,往往引起鳞茎腐烂,影响贝母产量。据我们1961—1974年先后在湖北贝母和浙贝主产区调查:如湖北利川县团堡大队,下种湖北贝母367斤,因为腐烂,仅收119.3斤,减产67.5%,61年利川县福宝山药材场,栽种贝母7000斤,由于遭受线虫和螨危害,引起贝母腐烂,仅收获400斤,减产94.3%。再如浙江鄞县浙贝在过夏期间,因病虫危害地下鳞茎最高达85.3%,平均66.1%,而健全鳞茎仅占 Fritillaria Liliaceae plants, commonly used traditional Chinese medicine. Medicinal part of the underground bulb. Due to the tender quality of watermelon, underground pests like to eat, easy to infect germs, often cause bulb decay, affecting the production of Fritillaria. According to our survey in 1961-1974 in the main producing areas of Fritillaria and Fritillaria, such as Hubei Lichuan County Mission Fort Group, the next species of Fritillaria of Hubei 367 pounds, because rot, only received 119.3 pounds, a reduction of 67.5%, 61 years Icheon County Fu Bao mountain yam field, planted fritillary 7000 kg, due to nematode and mite hazards, causing Fritillaria rot, harvest only 400 pounds, 94.3% reduction. Another example is Zhejiang Yinxian Zhejiang Pui during the summer, due to pests and diseases underground bulb up to 85.3%, an average of 66.1%, and only a healthy bulb
