摘　　要：对能源林柳树定向育种、良种繁育、林分密度、抚育管理、林分生长发育规律、病虫害防治、灾害防控和加工利用等技术进行了系统研究,对柳树能源林经济效益和环境效益进行了分析的结果表明:瑞典能源柳有短期和长期两个定向育种方案,品种主要包括蒿柳、毛枝柳及其杂种,良种繁育主要方式为机械化无性扦插繁育。林分密度为2.2~3.1×104株/hm2,生物量为10~16 t/hm2·a。病害主要包括叶锈菌和毛杆菌,虫害主要是柳瘿蚊和柳蓝叶甲。Sweden is leading in the development and utilization of biomass materials.This paper summarized the development of willow plantation forest for energy in Sweden.Breeding,propagation,spacing,tending,growth dynamics,pest&disease control,natural hazard control of willow plantation forest are studied,economic effects as well as environmental effects of willow plantation forest are analyzed.The results showed that willow breeding for energy includes long-term and short-term breeding plan,and cultivars were mainly Salix viminalis,S.dasyclados and their hybrids.Clonal propagation techniques is applied and planting density is ranged from2.2to3.1×104individual tree per ha,which resulted in the biomass production of10~16t/hm2·a.The disease and pest of willow include Melampsora epitea,Pseudomonas syringae,Rhabdophaga salicis,and Plagiodera versicolor.Heat&power cogeneration of biomass in Sweden is also introduced.This paper is expected to provide references for the research and development of plantation forest for energy in China.
