林木种子带精量播种技术的研究

A Research on the Precise Drilling Technology of Forest Seed-tapes

林木种子带精量播种技术是近年来发展起来的新型林业育苗播种技术,该项技术按照我国的林业育苗技术规程的相关要求进行研发设计,适用于苗圃落叶松、樟子松、云杉等树种的常规床作育苗播种作业。试验结果表明:可显著节约良种,减轻劳动强度,降低作业成本,提高劳动生产率;出苗均匀规则,疏密合理,便于苗期管理,有利于苗木生长及提高苗木质量。实现了林木育苗播种作业的工厂化和集约化生产。

Precise drilling technology of forest seed tapes is a new technology, emerged in recent years and suited for forest seedling cultivation. Research and design on it have been conducted in accordance with the requirements concerned in the regulations and rules, promulgated by the competent state departments, on seedling cultivation, suited for the regular bed seedling cultivation, in nursery, of larch, pinus var.mongolica and dragon spruce. Results from experiments have come up with obvious improvement in such aspects as saving of fine seeds, reduction of labor intensity, and raise of labor productivity; high and even rates of germination, desirable density for handling in the seedling stage and for the seedling growth and improvement of wood quality. The technology will help bring about the industrialization of forestry seedling cultivation and intensive production.
