【摘要】 为探索播期播量对菏麦21产量及产量构成要素的影响,试验采用裂区设计研究调查不同播期播量对其有效穗数、穗粒数、千粒重和产量的影响。结果表明,播期中10月5日(A1)播种的处理产量最高,为8 921.8 kg/hm~2;播量中B4播量(187.5 kg/hm~2)的产量最高,为8 526.1 kg/hm~2;A1B4处理产量最高,达9 220.0 kg/hm~2。可见菏麦21适于早播期大播量栽培,播期和播量对菏麦21具有一定的互作效应。更多还原

【Abstract】 In order to explore the effects of sowing date and sowing quantity on yield and yield components of Hemai 21, the split zone block design was adopted to investigate the effects of sowing date and sowing quantity on the effective panicle number, grain number per panicle, thousand grain weight and yield. The results showed that the treatment of sowing on October 5(A1) had the highest yield, with an average yield of 8 921.8 kg/hm~2, the treatment of sowing with 187.5 kg/hm~2(B4) had the highest yield, with an average yield of 8 526.1 kg/hm~2. The treatment of A1 B4 had the highest yield, with an average yield of 9 220.0 kg/hm~2. Therefore, Hemai 21 was suitable for early sowing and large sowing quantity, and sowing date and sowing quantity had a certain interaction effect on Hemai 21.更多还原
