- 摘要:
- 以2～6 a生苜蓿为研究对象，研究了不同种植年限苜蓿光合生理生态特性的季节性变化。结果表明：不同种植年限苜蓿的叶片光合速率（Pn）、蒸腾速率（Tr）、气孔导度（Gs）、叶面温度（TL）随着季节的推移总体呈下降趋势，胞间CO2浓度（Ci）、光合有效辐射（PAR）变化趋势相反；随种植年限的增加，叶片Pn和Tr总体呈递增趋势，而Gs和Ci的变化规律不明显，且5 a生和6 a生苜蓿Pn、Tr、Gs均最高，Ci最低，其生产能力较强；各生理生态因子间存在一定的相关性，且相关关系各异，相关程度也不同。
- Abstract:
- Taking 2～6 years alfalfa as test material,the seasonal changes of photosynthetic ecophysiological characteristics of different planting years alfalfa were studied.The results showed that,leaf photosynthetic rate(Pn),transpiration rate(Tr),stomatal conductance(Gs),leaf temperature(TL) of different planting years alfalfa showed a overall downward trend with seasons,the changes of intercellular CO2 concentration (Ci) and photosynthetic active radiation (PAR) were opposite.Along with the increase of planting age,the overall changes of leaf Pn and Tr were increasing,and the Gs and Ci variation were not obvious,5-year-old and 6-year-old alfalfa Pn,Tr,Gs were the highest,Ci was the lowest,and the production ability was stronger.There was a certain correlation between the physiological and ecological factors,and different correlation,correlation degree were also different.
