| 摘 要： | 研究了播期、播量、土壤类型、品种等因素对春播条件下冬小麦产量的影响。结果表明:小麦最适合播量为25万粒/667m2;其他因素产量效应的大小顺序为土壤类型>播期>品种,滩地产量显著高于砂地;随着播期的延迟,单位面积产量、穗数、穗粒数、千粒重降低;品种以弱冬性小麦豫麦13的产量最高。

| Abstract: | The experiment was carried out to study the influences of variety,sowing time,sowing rate and soil type on the yield and its components of winter wheat sowed in spring.It was shown that the proper sowing rate was 0.25 million grains/666.7m~2.The order of effects of other three factors on yield of winter wheat was: soil type>sowing date>variety.The yield in shoaly land was higher than that in sand land.With the sowing date delayed,the yield,the number of ears,the grains per ear and 1000-kernel weight were reduced.Among the three tested varieties,the yield of "Yumai 13" was the highest. |
