摘 要:竹柳具有生长快,出材率高等特点,可以作为解决林区林木资源枯竭的一种能源树种。为此,课题组于2015年引进"竹柳5号"在小兴安岭友好林业局进行造林试验。经过两年的观测表明,竹柳整体表现出了成活率高、生长快等特点。在同本地树种大青杨的对比试验表明,造林当年大青杨株高平均值比竹柳低66.97%,第二年低80.44%,差异明显。但同时试验也表明,竹柳虽然具有较高的抗涝性,但长时间的水涝仍然会使竹柳表现出生长量下降等现象。另外,竹柳在不同的造林密度下也表现出不同的性状特点。综上所述,竹柳在小兴安岭林区引种表现出了较为优良的性状,但这一性状是否具有持续性还应进一步观察。Salicaceae has the characters of fast growth and the high rate of output. It can be used as the forest resources to solve the exhaustion of forest energy. Therefore, the research group introduced the Salicaceae No. 5 in 2015 to carry out afforestation ex-periments in the Xiaoxing^nling Youhao forestry bureau. After two years of observation, the Salicaceae showed the characters of high emergence rate and fast growth. Compared with the local tree species, the average height of Populus euphratica was 66. 97% lower than that of Salicaceae in the first year and 80. 44% lower in the second year. The difference was obvious. At the same time, the ex-periment also showed that Salicaceae had a high waterlogging, but the waterlogging would still show the decline in growth and other phenomena after a long time. In addition, Salicaceae in different afforestation density also showed different characteristics. In summa-ry, Salicaceae in the Xiaoxing’anling forest area showed more excellent advantages,moreover, they should be further observed.
