Abstract: In order to study the effect of intercropping grass on the quality and yield of peach leaves and fruits in greenhouse in South Xinjiang, three treatments of intercropping triticale (T1) and trifolium (T2), CK were set up, the fuzzy mathematics membership function method was used to comprehensively evaluate the quality and yield indexes of peach leaves and fruits, so as to select the best intercropping treatment. The results showed that the intercropping with triticale and trifolium could increase leaf area, leaf thickness, chlorophyll content and leaf chemical content. Compared with CK, T1 and T2 treatments increased leaf thickness by 0.21 and 0.02 mm, total chlorophyll content by 0.27 and 0.10 mg·g^-1, total potassium content by 1.40 and 0.26 g·kg^-1, respectively. Intercropping grass significantly increased single fruit weight, vitamin C content, soluble sugar content and soluble solid content. Compared with CK treatment, single fruit weights of T1 and T2 treatments were increased by 14.80 and 10.28 g, soluble solid contents of T1 and T2 were increased by 1.63% and 1.26%, respectively. Intercropping grass also increased the fruit setting rate of fruiting branches and the yield per unit area. On the whole, the effect of intercropping grass with triticale on improving of fruit quality and yield was better than that of intercropping with trifolium, which provided theoretical basis for high-quality cultivation and production of greenhouse peach in South Xinjiang.
