柳树速生,适应性强,容易无性繁殖。它不仅是平原地区主要的用材树种,而且还是重要的水土保持和四旁绿化树种。柳树种类多,容易杂交,杂种柳树具有很强的生长势,采用优良杂种无性系造林,可以得到较高的增产效果。阿根庭和欧洲一些国家栽植柳树和杨树一样采用杂种。我国目前还未用杂种柳树造林,为了尽快采用杂种柳树或优良无性系造林,我们进行了十多年的柳树育种试验,培育出几种速生的杂种柳树。其特点是生长快,一般比对 Willow fast-growing, adaptable, easy asexual reproduction. It is not only the main timber species in the plains, but also an important soil and water conservation and four-sided tree species. Willow species, easy to hybrid, hybrid willow has a strong growth potential, the use of excellent clonal afforestation, you can get a higher yield. Argentine and some European countries planted willows and poplars as hybrids. In our country, the hybrid willow has not been reforested at present. In order to use the hybrid willow or the excellent clonal afforestation as soon as possible, we conducted the willow breeding experiment for more than ten years to breed several fast-growing hybrid willow trees. It is characterized by rapid growth, the general comparison
