研究了播期、土壤类型、品种几种因素对冬麦春播产量及产量构成因素的影响。结果表明,3种因素对产量效应的大小顺序依次为土壤类型>播期>品种。滩地产量显著高于砂地;随播期的延迟,公顷产量、每666.7m~2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。
The effects of sowing dates, soil types and varieties on sowing date and yield components of winter wheat were studied. The results showed that the order of the three kinds of factors on the yield effect was soil type> sowing date> variety. The yield of beach land was significantly higher than that of sandy land. With the delay of sowing date, the yield per hectare decreased every 666.7m ~ 2 spikes, grains per spike and 1000-grain weight. The yield of weak winter wheat Yumai 13 was the highest.
