Abstract: 1-year Camellia oleifera seedlings were planted at Lanju, Longquan of Zhejiang province in March of 2012, and interplanting of Arachishypogaea, Glycine max and was carried out in May of 2015. Biomass of interplanted crops was determined from July to harvest in the current year.Results showed that O. sativa had the most height growth, topped to 150.23cm at the date of harvesting. G. max had the highest biomassaccumulation, up to 769g, and had the highest root length of single plant, total fine root length and root surface area, with 33.33cm, 875.04cm and174.34cm2 respectively. The experiment demonstrated that G. max had the best root system for interplanting at C. oleifera stand.
