为探索化控在冬小麦高产栽培技术创建体系中的作用，以小麦品种（系）中麦175和轮选518为供试材料，研究了不同生育时期喷施化控剂吨田宝后冬小麦产量、品质及旗叶主要生理指标的变化。结果表明，起身期＋拔节期（ B2）处理在小麦生育后期（第35天）能更有效抑制旗叶叶绿素含量和氮素含量的降解，延长叶片功能期，差异达显著水平；不同化控处理对产量及其构成因素影响显著，喷施化控剂的3个处理均显著高于对照（不喷）；在品质指标中，沉降值和吸水率均以起身期＋拔节期（B2）处理显著高于B0（不喷）、B1（冬前苗期＋起身期）两处理。

To explore the role of chemical control in winter wheat yield cultivation techniques create system ,se-lected wheat varieties Zhongmai 175 and Lunxuan 518 to test for material to study the yield ,quality and flag leaf physiological changes after different periods of spraying of chemical control Duntianbao .The results show that ,Got up period+jointing stage ( B2 ) is more effective in inhibiting the degradation of chlorophyll content and nitrogen content and extend blade function of processing in the later growing stages (35 days),difference was significant;Dif-ferent chemical treatments on yield and its components significantly ,three treatments of spraying chemical control a-gents were significantly higher than the control ( No spray );Sedimentation and water absorption are Got up period +jointing stage(B2)significantly higher than B0(No spray),B1(Before winter seedling stage +got up period)two treatments.
