摘要
通过对旱冬瓜在良种选择、育苗技术、群落特征及应用等方面的研究结果进行总结,提出了旱冬瓜分布区自然条件差异悬殊,遗传分化极为明显,种源、个体差异很大等特点。针对目前存在着选育不充分、速生丰产栽培技术体系不完善、病虫害防治缺乏等问题,提出了加快良种选育、开展区域化栽培试验及速生丰产林培育技术的研究方向。
We summarized the current studies of Alnus nepalensis in breeding,seedling growth and community characteristics.We also found that the tree have significant genetic differentiation in different sources of provenance and diversity in individual trees in much diverse natural conditions of tree planted.In regard to current problems of less sufficiency in application of advanced breeding technologies,less perfection in cultivation of fast growth of tree and lack of management of pest and disease for Alnus nepalensis plantation,we proposed suggestions in accelerating tree breeding,regionalized cultivation experiment and developing new technology for fast growth breeding of the tree.
