摘要
系统地叙述了黄菠椤母树林林下栽植龙牙楤木的方法,研究结果表明,栽培密度为行距3m,株距2m,每穴栽3株,最适宜栽植坡向为北坡和东北坡.栽植后第3年开始净收入945元/hm2,其根、茎、叶都含有大量的微量元素,其中锌的含量特别高,1g干样品中含锌2.90～55.00μg.
The technique of cultivating common coral Chinese aralias under the seed trees of amur cocktrees was explained in systematic way.The result indicated that the cultivated density was that row pitch:3m;row spacing:2m.Three common coral Chinese aralias in one cave.The most suitable shope direction of planting was north or northeast.The net income was 945 yuan/hm2 after cultivated for three years.Their roots,stems and leaves contained macrotrace elements,in which the content of Zn is very high.It contains Zn 2.90～55.00 μg in 1 g dry sample.
