摘　　要：以"青薯6号"马铃薯为试材,对马铃薯叶面喷施植物营养剂,在不同时期测定马铃薯叶片的叶绿素、光合速率及块茎产量。结果表明:第1次喷"全佳福"、"海绿素"对马铃薯叶片的叶绿素a含量增加比较明显,随后再喷施"全佳福"、"海绿素",叶绿素a、叶绿素b、叶绿素总含量及光合速率的增加量比较少;"全佳福"、"海绿素"均能提高马铃薯叶片叶绿素a、叶绿素b、叶绿素总含量,从而提高了光合速率,增加了马铃薯块茎产量。Taking ＇Qingshuliuhao＇ patato as material,the content of chlorophyll,photosynthetic rate and the yield of potato tubers were determined.The results showed that the first spray Quanjiafu and Hailvsu,content of chlorophyll a in potato leaves more obvious increased,the second,after spraying Quanjiafu and Hailvsu,the content of chlorophyll a,chlorophyll b and total chlorophyll,photosynthetic rate increased less.Quanjiafu and Hailvsu ould improve the content of chlorophyll a,chlorophyll b,and total chlorophyll content,so enhancing the photosynthetic rate,and finally increased the yield of potato tubers.

关 键 词：全佳福 海绿素 叶绿素含量 光合速率 块茎产量
