摘　　要：通过2年试验,研究了马铃薯追施钾肥对产量及相关性状的影响。结果证明,追施钾肥能明显提高马铃薯的产量、淀粉含量,提高生育后期叶片叶绿素含量的光合强度。不同时期追施钾肥的效果不同,以现蕾初期追施钾肥效果最佳。Experimental study infouencing on output and correlation character of applying potassium to potato, takes two years in the Mudanjiang suburbs aguiculture factory of Heilongjiang Province. The result proved that applying the potassium fertilizer to be able obviously to enhance the potato output, the starch content, enhances the leaf blade chorophyll conternt and the photosynthesis intensity of birth later period. Applying the potassium fertilizer in different time will be slightly different,and the effect of applying the potassium fertilizer at the present flower bud initial perioed is bestj.
