摘要
刈割部位不同对羊草光合速率的影响不同。在土壤水分良好条件下,刈割全株之后,长出的再生叶片光合速率显著升高;刈割上位叶之后,残留的下位叶片光合速率有所增加;刈割叶片前部,残留的后部叶片光合速率未见变化。
The influences of various cutting positions on the photosynthetic rateof Aneurolepidium chinense were different. The photosynthetic rate of theleaf of aftermath increased markedly after cutting the whole plant. thephotosynthetic rate for the remaining leaves of the lower position roseafter cutting the leaves of the upper position. The photosynthetic ratefor the remaining rear half of the leaf was basically stable after the fr-ont half of it was cut.
