To increase the yield and quality of Paeonia ostii barks, the research of economic income under Juglans regia trees in difference cultivation management treatments were explored. Four treatments were designed in this study, removing flower bud (T1), clip deadwood and root tillers (T2), spraying Bordeaux mixture on the leaves (T3) and commonly management (T4, CK). The results showed that the yield of cortex moutan in total, first grade and second grade were significantly higher (p≤0.05) than CK, among these treatments, T3 reached to 102.1g per tree that was the highest grades. In quality part, T1 and T2 were not significant than treatment CK in paeonol contents, but the T3 was the significantly higher (p≤0.05) than CK and reached to 1.82% contents. In economic input, treatments were obvious higher than CK, and the T3 reached to 67780.5 RMB that was 13935.5 RMB higher than CK. The leaves disease might be main negative factor for yield and quality of cortex moutan in Luoyang area, Henan province, so spraying Bordeaux mixture with concentration bluestone: quicklime: water = 1: 2: 200 (w/w) on the leaves from middle May to harvest of Paeonia ostii interval 20 d at every year was the best methods in this study because it had small difficulty management, lower labour intensity and higher benefit results in suitable for application in the cultivation model of intercropping Paeonia suffruticosa under Juglans regia trees.
