摘要
以适宜甘肃河西灌区种植的10个春小麦品种（系）为材料,通过分期播种研究了不同气候条件下小麦籽粒产量及品质性状的变化规律。结果表明,不同播期间小麦籽粒产量、千粒重及沉降值差异显著,适期早播可提高产量并改善品质;播期对小麦品质的影响存在品种间差异,甘春20号、陇春22号、高原602、永良15号、陇春23号和8106的品质性状受播期影响相对较小;小麦灌浆期间14.4-26.7℃的日均温与蛋白质含量、湿面筋含量及沉降值呈显著或极显著负相关,小麦灌浆期间充足的日照有利于产量提高及品质的改良。
Ten spring wheat which adapt to plant in Hexi irrigation area were planted in different sowing dates to study the variation of grain yield and quality under different climatic conditions during grain filling. The results showed that grain yield, 1000-grain weight （TKW） and sedimentation volume had significant difference among sowing dates, the suitable early sowing date could achieve the simultaneous improvement of both yield and quality of spring wheat. The effect of sowing date on the yield and quality of spring wheat among different varieties. The results also indicated that Ganchun 20, longchun 22, Gaoyuan 602, Yongliang 15, Longchun 23 and 8106 were affected less by sowing date while Wuchun 2, Ganchun 18, 8104 and 8107 were affected more. The daily mean temperature was in the range of 14.4-26.7℃ during grain filling period which had a significant negative correlation with protein content, wet gluten content and sedimentation value. Abundance sunshine is propitious to improving yield and quality of spring wheat during grain filling period.
