摘要
利用缩节安（ＤＰＣ）和磷酸二氢钾（ＫＨ２ＰＯ４）单独和混合浸种的方法，对棉籽播前浸种处理，可以增加棉花叶片叶绿素含量，提高ＰＳⅡ光化学活性和原初光能转换效率，以及叶片光合速率。
Chlorophyll content,the potential activity of PSⅡ,the efficiency of primary conversion of light energy of PSⅡ and the photosynthetic rate in cotton leaves were all raised by soaking with single or mixed DPC and KH 2PO 4.The results also showed that the mixed application had better effects than that of single, DPC and KH 2PO 4 had a synergism on those aspects.
