Abstract: In order to improve production decline problem of Dictyophora spp. monoculture, Dictyophora indusiata （Vent. Pers.） Fisch. and Morchella vulgaris were chose as experimental materials, and five rotation models were conducted, including D. indusiata monoculture, M. vulgaris monoculture, D. indusiata-M. vulgaris rotation, D. indusiata-Brassica oleracea L. rotation and M . vulgaris- Capsicum annuum L. rotation. The yield and quality indexes of D. indusiata and M. vulgaris per unit area were determined for 3 consecutive years. The results showed that rotation can partly improve the yield and quality of D. indusiata and M. vulgaris when compared with monoculture treatment. Among the five treatment, the comprehensive performance of D. indusiata and M. vulgaris was the best in D. indusiata-M. vulgaris rotation. In this rotation model, compared with the monoculture, the yield, the number of fruit-bodies per unit area and the weight of single fungus of D. indusiata in the second and third year increased significantly. Furthermore, the pileus fresh weight, the fungus height, the stipe diameter and the length of reticulation significantly increased simultaneously. The ash content, crude protein, crude fat and crude fiber of D. indusiata under the same rotation model also increased slightly （no significant difference） than that of monoculture. In the second and third year under D. indusiata-M. vulgaris rotation model, the yield, the weight of single fungus and the number of fruit-bodies per unit area of M. vulgaris increased significantly when compared to the monoculture, respectively, and the ash content, crude fat and crude fiber content of M. vulgaris increased significantly when compared to the monoculture. The pileus length and diameter of the third year increased when compared to the monoculture. The ratio of pileus to stipe of M. vulgaris under the same rotation model was greatly increased. Under D. indusiata-M. vulgaris rotation, the morphology and quality of M. vulgaris were significantly improved.
