摘要： 试验系统的研究了在不同播期，日均温对强盛49的出苗速度及生育期的影响，研究结果表明：播期和强盛49的出苗速度以及生育期之间有真实的线性回归关系：Y=9.8335*EXP(-0.019806*X)，R=0.9118*；Y=131.0100*EXP(-0.003249*X），R=0.9884*；；日均温和强盛49的生育期也存在真实的线性关系：Y= 464.2999-14.2397X，R=0.9849* 。上述方程可以为选择适宜播期提供理论依据。

Abstract: The test had systematically studied that effect on speed of seeding and growth period of Qiangsheng49 under the different sowing dates by daily mean temperature. The results show that: the sowing date has the relationship of liner regression both the growth period and Speed of seeding . They are Y=9.8335*EXP(-0.019806*X)，R=0.9118*；Y=131.0100*EXP(-0.003249*X），R=0.9884*..And the daily mean temperature and the growth period have the relationship of liner regression: Y= 464.2999-14.2397X，R=0.9849*.All of the Equations will take more theoretical foundation for the suitable sowing date.
