对新疆伊犁引种的黑杨派30个品种、品系16a的生长量、形态特征、病虫害冻害分析,以健杨作为对照,通过方差分析表明,不同品种间树高和胸径的差异极显著(p<0.01),黑杨派各树种间树高和胸径以及冠幅直径和冠幅高之间呈极显著正相关(p<0.01),胸径和冠幅高间呈显著正相关(p<0.05)。通过分析,适合伊犁的优势品种有中林23、中林28、中林、78-8、78-133。
The analysis of the growth, morphological characteristics and frostbite of 30 species of black poplar introduced in Xinjiang Ili and analysis of frost damage of pest and disease caused by Populus davidiana showed that there was a significant difference in tree height and DBH among different varieties (p < 0.01). There was a significant positive correlation (P <0.01) between the tree height and the DBH, the crown diameter and the crown height among all the tree species. There was a significant positive correlation between DBH and crown height (p <0.05). Through analysis, the dominant varieties suitable for Ili are Zhonglin 23, Zhonglin 28, Zhonglin, 78-8,78-133.
