【摘要】 在研究杉木良种子代生长适应性的基础上,对所筛选8年生杉木优良个体与气候条件相适应进行研究,结果表明:不同优良个体在高、胸径与材积生长表现不同适应性;在2011—2016年明杉6、10号高生长表现明显的生长下降趋势,生长量趋于平均值个体,其他个体能表现优良生长特性;在2015年降雨量偏大和夏季生长期日最高温度基本低于35℃气候异常年份,明杉4、6、9号表现良好的高生长,明杉9号高生长达3.5 m,而明杉1、12号等个体在2015年生长量低于其他年份,明杉8、9、10号有很好的胸径生长量,其他个体胸径生长则表现略低于上一年;材积生长变化与胸径、树高保持一致性,综合树高、胸径与材积生长,明杉4、6、8、9、10号个体更适宜于肥沃的土壤与光照条件相对较弱的、湿度相对大的立地条件,明杉1、2、3、5、7、11、12、13号个体表现更适宜于相对的高温、干旱与较瘠薄的立地条件。更多还原

【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 indicated 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 heightgrowth 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.1 and 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.更多还原
