摘要
于2006—2008年采用北京汉力淼有限责任公司生产的B J2101L型保水剂在黑龙江省半干旱区进行了造林试验,试验结果表明,按照不同剂量施用,平均可使造林成活率提高10%以上,干旱年份可提高20%以上;同时可促进苗木生长,其中可使红皮云杉高生长提高0.7 cm,樟子松高生长提高1.7 cm,小黑杨高生长提高19.9 cm;对速生杨的促进作用要大于针叶树。
Afforestation experiments were conducted in semiarid area in Heilongjiang province during 2006-2008 by using BJ2101L water retaining agent which was produced by Beijing Hanlimiao Limited Liability Company. Result shows that: treated with different doses by using BJ2101L water retaining agent,survival rate, which can be increased by above 10% averagely, can be increased by above 20% in dry year, it also can promote growth of seedlings at the same time, height growth of Picea koraiensis, Pinus sylvestnis vat. mongolica Litv. , Populus × xiaohei T. S. Hwang et Liang can be increased by 0.7, 1.7, 19.9 cm among them; promotion on fast-growing poplar by BJ2101L water retaining agent is greater than that on coniferous trees.
