| 摘 要： | 以郑单958、丹玉39为试材,研究播种期对玉米生育期、籽粒灌浆速率、农艺性状和产量的影响。结果表明：在不同播期条件下,郑单958均比丹玉39生育期少12d左右,且播种越晚,生育期越短;两品种相同播期的灌浆速率变化规律一致;郑单958的千粒质量、穗粒数、株高、穗位均低于丹玉39;5月14日播种的玉米产量最高。

| Abstract: | The effect of maize sowing period on its growth period,kernel milking rate,agronomic traits and yields were studied,taking Zhengdan 958 and Danyu 39 as the study subjects.The results show that under various sowing periods,the period of duration of Zhengdan is always 12 days fewer than that of Danyu 39,and the later the sowing date,the shorter the growth period.The two varieties show the same changes in milking rate when at the same sowing date.The thousand grain quality,corncob numbers,height,and corncob po... |
