为探讨寒旱区马铃薯高产高效栽培技术，以耐寒旱马铃薯品种陇薯3号和喜湿热品种LK99为材料，研究了塑膜小拱棚处理对马铃叶片叶绿素特性、PSU荧光猝灭和吸收光能分配的影响。结果表明：塑膜处理后，两个马铃薯品种叶片叶绿素含量、叶绿素b／a、Fv／Fm、Fv’／Fm’、ФPSⅡ、ETR、qP和Pc较对照有不同程度升高，qN和Hd降低，Ex变化不大；这种影响对喜湿热马铃薯LK99表现更突出。说明塑膜提供的高温高湿环境有利于两种生态型马铃薯试管苗移栽和光合效能的提高。
為探討寒旱區馬鈴藷高產高效栽培技術，以耐寒旱馬鈴藷品種隴藷3號和喜濕熱品種LK99為材料，研究瞭塑膜小拱棚處理對馬鈴葉片葉綠素特性、PSU熒光猝滅和吸收光能分配的影響。結果錶明：塑膜處理後，兩箇馬鈴藷品種葉片葉綠素含量、葉綠素b／a、Fv／Fm、Fv’／Fm’、ФPSⅡ、ETR、qP和Pc較對照有不同程度升高，qN和Hd降低，Ex變化不大；這種影響對喜濕熱馬鈴藷LK99錶現更突齣。說明塑膜提供的高溫高濕環境有利于兩種生態型馬鈴藷試管苗移栽和光閤效能的提高。

In order to probe into the cultivation techniques of high yield and high efficiency of potato in cold and arid reagions,with the materials of Longshu No. 3 and LK99, the effect of plastic film on potato chlorophyll, PS Ⅱ fluorescence quenching and absorbed energy distribution was studied. The results showed that compared with the control, plastic film process caused potato leaf chlorophyll content, chlorophyll b/a,Fv/Fm,Fv＇/Fm＇, ФPSⅡ ,ETR,qP find Pc increased qN and Hd decrease,Ex scarcely unchanged. The effect had more prominent impact on LK99; It demonstrated that plastic film could provide a hotter and humid environment which conducive to LK99 and Longshu No. 3 transplanting adaption and absorbed energy distribution.
