| 摘 要： | 马铃薯叶片中叶绿素含量在整个生育期内呈双峰曲线变化 ,峰值分别出现在块茎形成期和淀粉积累期 ;增施氮、磷、钾肥 ,尤其是氮、磷肥 ,可以提高马铃薯叶片中叶绿素含量 ;采取合理的栽培措施 ,防止叶片的早衰 ,提高叶片叶绿素含量 ,使马铃薯群体在产量形成的关键时期具有较高的光合活性 ,是获得马铃薯高产的重要保证。

| Abstract: | The change of chlorophyll contents in the leaves of potato during the whole period of growth and development was of two peaks, with one peak appearing in the stage of tuber formation, and another in the stage of starch accumulation. Increase in application of N, P, and K, particularly N and P fertilizers,could lead to increase in the chlorophyll content. High tuber yield could be achieved by using agronomic measures which can prevent leaves from early senescence,increase chlorophyll content of leaves, and maintain potato plants at a high level of photosynthesis rate in the crucial stage of yield formation. |
