Abstract The effect of arbuscular mycorrihiza（AM）fungi on growth, yield, and quality of sweet pepper（Capsicum annuum L.）under soil cultivation and rich organic matter soil were studied. The results showed that AM fungi improved the root activity of sweet pepper and promoted the germination and growth of fibrous root. The chlorophyll content and photosynthesis of sweet pepper leaves were significantly improved by AMF inoculation. Sweet pepper could grow better in rich organic matter soil than in ordinary soil. Compared with the control, AMF inoculation treatment significantly increased the yield of sweet pepper, and the nutritional quality of sweet pepper was also improved, as the nitrate content decreased and the contents of total sugar, VC and crude protein increased.
