| 摘 要： | 以大田栽培条件下4a生刺五加为试材,进行光合日变化研究.结果表明:刺五加光合日变化有午休现象,光强以11:00～13:00为高,上午的光合速率较午后为高,在上午10:00左右光合速率达到最高；全光处理光强高于遮光处理200～500 lx左右,遮光处理光合作用弱于全光处理；全光处理光强一直在500 lx以上,光合速率降幅小,而遮光处理光强在下午15:00以后下降很快,低至100～400 lx,光合速率降幅大.遮光处理能使光强在400～1 200 lx范围内,满足刺五加对光的需求,较适于阴生植物的生长；而6月中旬与9月中旬光强低,光合速率也低,说明遮光过早和撤覆延迟能降低刺五加光合速率,因此,建议合理的遮光时间为6月中旬至8月下旬,以保证刺五加高效利用光能,提高光合速率.

| Abstract: | Diurnal changes of photosynthesis was studied of Acanthopanax senticosu(Rupr.et Maxim.)Harms.of 4-year-old planted in field.The resuls showed that there exist noon break and the intensity of light was the highest from eleven to thirteen o'clock,the photosynthetic rate before noon was higher than that of afternoon and it reached peak at ten o'clock;the intensity of light was higher of full light treatment(TL) than that of shade treatment(TS) by 200 to 500 lx,the photosynthesis of TS was not so high as TL;the... |
