胡桃楸是东北地区珍贵用材树种之一。材质坚硬致密,纹理美观,质轻耐腐,用途很广,经济价值很高。一九五一和一九五二两年,我们在海拔300——480公尺的山坡休耕地上直播造林528公顷,初植密度4444株/公顷,成活率达85%以上。后来因未能及时间伐,遭受清理站杆砍柴的破坏,现存1.500——2.200株/公顷。最近我们调查总结这一经验教训。
Juglans mandshurica is one of the precious timber species in Northeast China. Material is hard and dense, beautiful texture, light and decay resistance, a wide range of uses, high economic value. In 1951 and 1952, we planted 528 hectares of direct seeding on fallow arable land at 300 - 480 meters above sea level with a planting density of 4444 plants / hectare and a survival rate of over 85%. Later, due to failure and time-lapse, they suffered from the destruction of station bar firewood and the existing 1.500--2.200 plants / hectare. Recently, we surveyed this lesson.
