摘　　要：在山西长山药主产地太谷、平遥和汾阳进行了生态配方施肥试验,结果表明,以有机肥、无机肥和微生物肥料三者按一个合理比例配施的生态配方肥,能够不同程度地降低炭疽病、叶斑病、红斑病等长山药主要病害的病情指数,并能明显地提高其产量。其中,以配施防病抗重茬菌系为主、营养菌系为辅的生态配方肥的施用效果更好一些,其既能有效地抑制长山药病情发展,又有利于提高其产量,生态效果比较明显。In this study,the experiment of different ecological formula fertilization treatments was carried out in Taigu,Pingyao and Fenyang,the major Chinese yam growing areas in Shanxi province.Results showed that the ecological formula fertilization that combined proper application of microbial fertilizer,organic and inorganic manure could reduce the disease index of anthracnose,leaf spot,red leaf spot and some other major diseases,and remarkably increase the yield of Chinese yam as well.Among these treatments,the effect of ecological formula fertilization with resistance strains of disease prevention mainly based on（T1） was much better.It could not only inhibit the development of diseases,but also improved the yield of Chinese yam.At the mean time,its ecological effect was more obvious.
