摘要
为了充分提高林地的生产潜力,对落叶松-龙牙葱木这一立体栽培模式进行了探讨。设计了一整套龙牙葱木的育苗及栽培技术,并对落叶松和龙牙葱木的生产量及龙牙葱木各营养器官的化学成分含量进行了测定;同时对落叶松-龙牙葱木这一混交模式的经济效益进行了分析。结果表明:这一混交模式可以大大提高经济效益,使林地利用率得到显著提高,是值得在黑龙江东部山区推广的混交模式。
A stereo planting mode of Larix gmelinii and Aralia elata was approached in order to effectively improve the productive potential of forest lands. A set of techniques for seedling cultivation and planting of A. elata were designed, and the yield of L. gmelinii and A. elata and the content of chemical components in various vegetative organs of A. elata were measured. Meanwhile, the economic benefit of the mixed pattern of L. gmelinii and A. elata was analysed, Result showed that the mixed pattern can increase the economic benefit and significantly improve land utilization, which can be popularized in the eastern mountain areas of Heilongjiang Province.
