| 摘 要： | 剪除地上部分对冬小麦效应明显：（１）株高降低。剪除时间愈迟，株高降低愈多。（２）生育期延长、抽穗期、开花期和成熟期延迟。（３）早期剪除地上部分，产量降低甚少；剪除时间愈迟，产量降低愈多。

| Abstract: | A study showed that cutting off the terranous parts had great influence to winter wheat: i) lowered plant height. The later the cutting time was, the lower it was; ii) extended the growth period of the treated plants, reduced in later time for jointing, flowering and maturation plases; iii) reduced the yield. In early treutment no significant yield reducing could be measured. The later the cutting time was, the more the yield decreased. |
