| 摘 要： | 为研究马铃薯主茎数量以及打顶对马铃薯生长的影响,以丽薯7号为材料,通过盆栽试验研究人工控制主茎数量以及打顶的物理方法对马铃薯生长的影响。研究表明:每穴3茎是较好的群体密度调控,能够提高马铃薯产量。打顶有利于控制马铃薯株型,削弱其顶端优势,减少地上部茎叶对地下块茎的抑制,增加了马铃薯产量。

| Abstract: | Using cv.Lishu 7 as plant material,the influence on potato growth of artificial control of main stem quantity and topping was studied.The results indicated three stems per hill were optimal for potato yield;topping was beneficial for shaping plant,weakening apical dominance,balancing growth between above ground and under ground growth,and thereby increasing potato tuber yield. |

| Keywords: | main stem topping potato yeild |
