摘要
本文描述了红皮云杉的造林和抚育技术。研究表明,该树种适应性强,易成活,生长快。土层30cm厚的半阴半阳中下部坡地为其造林最佳立地条件,最佳初植密度为4400株/hm2,透光抚育起始年限是造林后第4年,上层郁闭度不大于0.3,宽度应以伐8m留8m为宜。
This paper describes the technique of afforestation and tending. The results show that the adaptability the specis is reasonable, easily survives, grows well. Optimum site of affosestation as: topsoil is 30cm in thickness; hillside field field under middle slope and with northeast or northwest direction. Optimum density is 4400 seedlings/hm2, Beginning of tending is fourth year ofter afforestation. Canopy density of upper layer is not more than 0. 3 wideth of tending scrip should he interval 8m
