自2004年以来,中国先后从瑞典引进了一批速生能源柳品种和观赏品种,已在陕西杨凌、黄龙和桥山建立种质资源圃1.53公顷,造林面积2.67公顷。不同季节、软枝扦插和硬枝扦插成活率在90%以上;与当地乡土柳树比较,高、径、生物量生长量平均高出2～3倍,比其他乡土树种高4-5倍;不同品种间存在差异,以能柳C和能柳E最好;水分关系参数和酶等耐旱性指标比对照种高50%,保持了抗逆性;耐修剪、平茬、整形,园林观赏性良好。
Since 2004, China has successively introduced a number of species and ornamental species of fast-growing energy sources from Sweden. It has set up 1.53 hectares of germplasm resources in Yangling, Huanglong and Qiaoshan in Shaanxi Province and has an afforestation area of 2.67 hectares. The survival rate of softwood cuttings and hardwood cuttings was over 90% in different seasons. Compared with the native native willow trees, the growth of height, diameter and biomass was 2-3 times higher than that of other native trees, There are differences among cultivars, and the best is Corynebacterium tenuiflora L. and cannonball E; the drought-resistance index of water-related parameters and enzymes is 50% higher than that of the control, maintaining the resistance; the ability of pruning, stubble cutting, plastic surgery, ornamental ornamental good.
