摘　　要：对山西境内的主要山药地方品种与引进品系的生物学特性、抗逆性能及其生产力水平进行了对比分析,并探讨了生态培肥效果。结果表明,太谷绵山药、平遥长山药、汾阳菜山药的萌芽出苗能力强,综合性状好,生产力水平高;生态培肥技术可提高太谷绵山药的产量和改善其品质;引进的新品种对山西气候条件的适应性差,病害也相对较重,需要进一步的适应性驯化与培育。In the comparative analysis of biological characteristics, resistances and its productivity levels, as well as the effects of ecological fertilization was discussed in Taigu, Shanxi province. Results showed that, Taigu yam, Pingyao yam and Fenyang yam had good germination ability, good comprehensive charaeteristics and high productivity. The ecological fertilization technology could not only increase yield but also improve quality of Chinese yam. The new introduced species failed to adapt to the climate conditions in Shanxi province, and its disease was also relatively serious. Further domestication and cultivation were needed.
