Comparative Study on Growth Adaptability of Tolerance Barren Elites of Cunninghamia lanceolata Under Different Climate Conditions
摘要
Abstract
The adaptability of barren tolerance elites of screened 8-year-old Cunninghamia lanceolata to the climatic conditions was studied based on the growth adaptability of barren tolerance elites of C.lanceolata,it indica-ted that the height, breast-diameter and timber-volume growth of the different elites fitted on the different growth condition.The height-growth of Minshan No.6 and No.10 were downtrend and tend to the average baby,the height-growth of another were better from 2011 to 2016. The height-growth of Minshan No.4,No.6 and No.9 were of the especial fast-growth and the height-growth of Minshan No.9 got 3.5 m,but the height-growth of Minshan No. 1and No.12 were lack of another a particular year, because of more rainfall capacity and under 35℃ of air temperature during growing period in 2015. The breast-diameter growth of Minshan No.8, No.9 and No.10 were well and the breast-diameter growth of another elites were lack of up-year in 2015. The timber-volume growth and change were the same of the growth of height and breast-diameter, the growth of height and breast-diameter and timber-volume indicated that the growth adaptability of Minshan No.4,No.6,No.8,No.9 and No.10 will be more fitting on the growth-condition of the relatively lack light and bigger humidity and fertile soil,the growth adaptability of Minshan No.1,No.2,No.3,No.5,No.7,No.11, No.12 and No.13 will be more fitting on the growth-condition of the relatively height-temperature and drought and barren soil.关键词
