摘 要:以金黑杨无性系1号、2号、3号为试验材料,108杨为对照,在晋北、晋中、晋南进行区域化造林试验,测定6年生时金黑杨无性系的生长量,对比金黑杨与108杨的抗性及材性,并采用隶属函数法进行综合评价。结果表明,金黑杨3个无性系的树高、胸径、材积和抗虫性均高于108杨,且除树高外,其它指标均显著高于108杨;金黑杨1号、2号的抗寒性指标均高于对照,1号的材性最好。综合隶属函数值最高的是金黑杨1号(11.550 1),其次是2号(9.959 8)和3号(8.020 3);108杨的最小,仅为2.292 6.金黑杨3个无性系均是适合在山西杨树适生地区推广应用的高效、高产杨树新品种。Regional afforestation experiments were carried out in the northern, middle and southern part of Shanxi province using P. x deltoides L. ' Jinheiyang 1,2 and 3 ' as testing materials and Populus x euramerlicana cv. ' Guariento' as con- trast. The resistance and wood properties of P. x deltoides L. ' Jinheiyang' and Populus x euramerlicana cv. ' Guariento' were compared and evaluated comprehensively using membership function method by measuring the growth amount when they were 6-year-old. Results showed that the height, DBH, volume and insect resistance of P. x deltoides L. ' Jinheiyang' were higher than that of the contrast and the indices were significantly higher than that of the contrast except the tree height. The cold resistance indices of P. x deltoides L. ' Jinheiyang 1,2' were higher than those of the control, and the wood prop- erties of. x deltoides L. 'Jinheiyang 1 ' were the best. The comprehensive membership function value of P. x deltoides L. ' Jinheiyang 1 ' was the highest( 11. 550 1 ), then were P. x deltoides L. ' Jinheiyang 2' (9. 959 8) and P. x deltoides L. ' Jinheiyang 3' (8. 020 3), while the value of the contrast was lowest ( only 2. 292 6). P. x deltoides L. ' Jinheiyang 1,2 and 3' belonged to the high efficient and high yield new poplar varieties that could be extended and planted in the poplar suitable regions in Shanxi province.
