摘要
论述了现阶段国家对林业的需求是生态环境改善及木材"量"的严重短缺,林业用材林培育目标是提高林木产量,为此育种的关键任务是速生高抗林木新品种培育,其培育重点是高质量营养体的营养生长问题。在种业发展方面苗木生产比重远远大于种子,无性系林业繁育技术的发展,进一步提高了苗木生产的比重。在现阶段,林木品质方面的要求可以通过树种的选择得到解决,也更符合林业发展实际;林木抗性育种的难点主要是林木对物理环境和病虫害的抗性要求更高,除了一般的条件限制因素之外,还需要经历整个培育周期数十年内的极端条件。鉴于林业的特殊性,应该得到国家更多的支持,从而解决我国林业面临的国民经济发展、生态环境改善及低碳经济需求的三重压力;同时指出林业种苗业科技创新对"速生高抗林木新品种高效培育技术体系与产业化"的重要性。
