| 摘 要： | 本试验以泰农18、济麦22为试材,研究不同播期对冬小麦产量及构成因素的影响。结果表明:随播期推迟,小麦生育期推迟,穗数逐渐降低,产量及千粒重先升后降,产量峰值出现在S2处理;泰农18随播期推迟穗粒数先升后降,而济麦22则先升后降,之后又升高。

| Abstract: | The effects of different sowing dates on grain yield and its components of winter wheat were studied with the cultivars Tainong 18 and Jimai 22.The results showed that with the delaying of the sowing date,the growth period of winter wheat was postponed;the spike number decreased gradually;the grain yield and 1 000-grain weight increased firstly and then decreased,and the peak value was present in S2 treatment.The grain number per spike of Tainong 18 increased firstly and then decreased,while that of Jimai 22 increased firstly,then decreased,and increased at last with the sowing date was delayed. |
