杉木分布区广,由于分布区内气候、地貌土壤等生态条件的不同,经过长期自然选择和人工选择,保存了生产力相差很大的不同种群。我省武夷山与鹫峰山、戴云山相夹的中间地带是著名的杉木中心产区,参加全国第一次杉木地理种源试验的莱州试点就在此范围内,桃源试点在其南部边缘。苗期及幼树阶段的试验初报指出:苗期生长状况所表现出的种
Cunninghamia lanceolata is widely distributed. Due to the different ecological conditions such as climatic and geomorphic soil in the distribution area, long-term natural selection and manual selection save different populations with greatly different productivity. The Wuyishan and Jiufeng Mountain and Daiyunshan in the middle of the province are the famous fir center producing areas. Laizhou pilot participating in the first Chinese fir geography provenance test is in this range. Taoyuan pilot is on the southern edge of it. Seedling and sapling stage of the trial reported that: seedling growth conditions shown by the species
