摘要
通过对榆杂２９制种亲本特征特性的观察，提出榆杂２９制种父母本播种差期以叶龄差为主是实现花期相遇的基础，采取综合农艺措施促使双亲平衡生长是实现花期相遇的保证．
This paper reports that to observe Yuza 29s characters shows the difference of leaf age is main base of sowing date difference of father and mother plants.Integrated agronomic practices can have father and mother plants balance growing and it will ensure synchronous flowering.More fertilizing to father plants only might increase spikelets and pollen quantity,and it is an effective way for high yield of seed production.
