遮阴对朝鲜淫羊藿生长的影响

Effect of Shading on Growth of Epimedium koreanum Nakai.

[目的]探讨遮阴对圃地栽培的朝鲜淫羊藿植株生长的影响。[方法]设置遮阴和对照2种处理方法,连续观测3年朝鲜淫羊藿株数、株高、叶片长、叶片宽和收获量。[结果]遮阴的朝鲜淫羊藿株数、株高、叶片长、叶片宽和收获量均逐年递增,且前4项指标更接近于野生朝鲜淫羊藿。对照组的朝鲜淫羊藿在栽植第1年被过强的光照灼伤,导致植株产生抗逆性,生长指标均低于遮阴组,并在第2年全部死亡。[结论]在圃地栽植朝鲜淫羊藿时,必须加盖遮阴网,且遮阴强度最好为70%以上。

[Objective] To investigate the effect of shading on growth of nursery cultivated Epimedium koreanum Nakai..[Method]Two treatments of shade and control were established,the number,plant height,leaf length,leaf width and yield of E. koreanum were continuously observed for three years.[Result]The number,plant height,leaf length,leaf width and yield of shaded E.koreanum increased year by year,and the first four indexes were closer to the wild ones.The controlled group was burned by high light for the first year,resulting in resistance to the plant,and the growth index of the controlled group was lower than the shaded group,and all of controlled plants died in the second year.[Conclusion] Shading is necessary for nursery cultivated E.koreanum and the best shade intensity is more than 70%.
