柳树生长快,适应性强、易繁殖,用途广泛,是平原地区和低湿滩地以及城乡绿化的重要树种。我所从1983年开始,先后从江苏林科所、宁夏、河北等地,引进柳树品种(无性系),1984年春进行品种的苗期测定试验。根据三年试验结果,从引进的柳树品种中初选出109柳、98柳、旱快柳、通天柳、黑皮柳等5个比较好的品种。在干形、抗性、速生等方面均超过当地最佳树种——青皮柳。现将试验结果报告如下: Willow grow fast, adaptable, easy to multiply, wide range of uses, is an important species of plain and low wetland and urban and rural greening. Since 1983, we have introduced willow varieties (clones) from Linke, Jiangsu, Ningxia, Hebei and other places. In the spring of 1984, we conducted seedling determination tests. According to the results of the three-year trial, 109 varieties of willow, 98 willow, dry fast willow, Panthera tigris alba and black broussonetia papyrifera were selected from the introduced willow varieties. In dry, resistant, fast-growing areas are more than the best local tree species - green Pi Liu. The test results are reported as follows:
