摘　　要：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 affects of variety,sowing time and types of soil on yield and itscomponents of winter wheat sowing in spring were studied in this paper.It wasshowed that the order of affects of three factors on yield of winter wheat was thatthe type of soil>sowing time>variety.The yield in shoaly land was higher thanthat of sand land.With the sowing time was lating,the yield per hectare,the earsper 666.7 m^2,the grains per ear and 1000 grain weight were reduced;among threevarieties,the yield of 'Yumai 13' was the highest.sowing time;;types of soil;;variety;;winter wheat sowings in spring;;yield;;yield components factor
