落叶松是针叶树种中的速生树种。材质优良、分布广、适应性强、为营造速生丰产用材林的主要树种之一。目前落叶松造林还是以人工植苗为主,直播尚有一定困难,因此落叶松的育苗工作还是一项重要的课题。特别是在林区环境由于地势高寒、无霜期短、落叶松育苗受自然条件及技术措施所限,当年生苗高平均不超过5厘米;同时产量也低,每平方米只有400—600株。这不仅大大的提
Larch is a fast growing tree species in coniferous species. Material quality, wide distribution, adaptability, in order to create fast-growing high-yield timber one of the main species. Larch afforestation is still mainly artificial planting seedlings, live still have some difficulties, so larch nursery work is still an important issue. Especially in the forest environment due to high terrain, frost-free period is short, larch seedlings by the natural conditions and technical measures are limited, the average annual height of not more than 5 cm; at the same time the yield is low, only 400-600 per square meter. This is not only a big mention
