- 摘要:
- 以1年生两面针扦插苗为试材，研究了不同水分胁迫处理对两面针的净光合速率、叶绿素含量、叶片含水量、荧光效应、产量的影响。结果表明：水分胁迫抑制了植株的正常生长，但轻度胁迫对植株的影响较小，尤其是对于以根部为有效利用部位的两面针影响十分微弱。结合生产实际，综合比较得出，人工栽培条件下保持土壤田间持水量的64%左右符合生产实际需要。
- Abstract:
- Taking one-year seedlings Zanthoxylum nitidum cuttings as test materials，the effect of different water stress treatment on Zanthoxylum nitidum in net photosynthetic rate，chlorophyll content，leaf water content，the fluorescent effect，yield were studied.The results showed that，under the water stress condition，the growth of the plants was inhibited，but mild water stress had little effect on plants，especially for Zanthoxylum nitidum，that roots were used as medicinal parts，the influence was very weak.Combining the productive practice，by integrated analysis and comparison，it was concluded that keeping the soil field capacity about 64% conformed to the production reality under the condition of artificial cultivation had the feasibility of operation.
