马铃薯生长后期叶片对产量的影响

Effects of Leaves on the Yield of Potato in Late Growing Period

[目的]研究马铃薯生长后期叶片对产量的影响。[方法]通过不同时期去叶处理方法,对马铃薯生长后期叶片对马铃薯结薯数、大薯率及产量的影响进行了探讨。[结果]马铃薯终花期后叶片对结薯数影响不大,而对大薯率和最终的产量影响较大。[结论]马铃薯终花期前马铃薯植株结薯数量已经确定,而大薯数及最终产量的形成与后期叶片仍有一定的关系。在生产上应综合利用各种措施,调控植株后期叶片生长,延长叶片的功能期,为马铃薯丰产奠定基础。

[Objective]The aim was to survey the effects of leaves on the yield of potato in late growing period.[Method]The tuber number,large tuber number and the yield of potato in late growing period were discussed.[Result]The effect of leaves on the tuber number was not significant,while that on the large tuber number and yield of potato in late growing period were significant.[Conclusion]The tuber number of potato had been confirmed before the late flowering,and the large tuber number and the yield of potato were related to leaves.In practical production,applying various measures to regulate the growth of leaves could prolong the functional period of leaves,which would provide basis for the high yield of potato.
