摘要
为选育生长快、干形好的优良杨树无性系,用53个黑场派无性系在山东省沂水县进行造林试验,测定并计算各无性系第5年的胸径、树高、冠幅、材积、树干通直度、树干尖削度等,结果表明各指标在无性系间差异极显著,经多元统计分析,将参试无性系分为4类,其中4159、江淮2号、1620、81、1627、1618、1617、1601等8个无性系,具有生长量大、干形较好等优良特性,适合在鲁中南地区推广应用。
Fifty-three Section Aigeiros clones were used for afforestation experiments in Yishui County,Shandong Province,and the diameter at 1.3 meters above the ground,tree height,crown width,volume,trunk straightness,and trunk taper of each clone in the fifth year were measured and calculated.The results showed that there were significant differences among the clones for each index.Eight clones,including 4159,Jianghuai 2,1620,81,1627,1618,1617,and 1601,have excellent characteristics such as large growth and good stem shape,making them suitable for promotion and application in the central and southern regions of Shandong.
