Abstract

Chinese torreya has only been cultivated in the regions such as Mt. Kuaiji, Mt. Tianmu and Yellow Mountain. The two places, Chenchai village of Zhuji City and Zhuxi village of Sheng County, were taken as main recognizing sites according to weighting factors such as 17 meteorological elements during 22 years and 8 soil factors, and Forestry Research Institute of Zhuji City as waiting recognizing site. The results showed that TDR (Chencai)=68.270 and TDR (Zhuqi)=36.567, which indicating that it's not suitable for introducing Chinese torreya into the locality of Forestry Research Institute of Zhuji City, there the yield of Chinese torreya introduced in 1959 was no more than 1/3 of that in the main recognizing site just with the causes of elevation, soil texture, PH, organic matters and fertility.
