    Discussion on compound management techniques of Chinese fir and Polygonatum cyrtonema

    • 摘要: 开展杉木、多花黄精复合经营主要技术措施试验研究,结果表明:上层林郁闭度在0.5~0.7之间较适宜多花黄精生长发育;在杉木林中套种多花黄精,以保留杉木株数750株/hm的多花黄精生长发育较好;适度的林地清理是必要手段,整床处理的多花黄精块茎产量较高;摘花截顶处理比不处理(即任其生长,不摘花、不截顶)块茎产量增加17.6%。杉木林间伐套种多花黄精,有利于培育杉木大径材。杉木、多花黄精复合经营是一种先进、合理、有效的经营模式,可以在林业生产中推广应用。

       

      Abstract: In this paper, compound management techniques of Chinese fir and Polygonatum cyrtonema were studied. The results showed that the suitable condition for growth and development of Polygonatum cyrtonema was when canopy density in upper forestry ranged between 0.5 and 0.7. When interplanting Polygonatum cyrtonema into Chinese fir forestry, the remained number of Chinese fir was 750 individual plants per hm was favorable for better growth and development of Polygonatum cyrtonema. Moderate clearance in forestry is a necessary method. The tuber yield of Polygonatum cyrtonema in treated field was higher. Defloration and decapitation of Polygonatum cyrtonema could obtain higher yield than that of non-treated plants (grow in wild manner, without defloration and decapitation) by 17.6%. So, Polygonatum cyrtonema could be interplanted into Chinese fir forestry was conductive to the cultivation of Chinese fir. Compound management of Chinese fir and Polygonatum cyrtonema is an advanced, rational and efficient management pattern and could be extended and applied in forestry production.
