化学调控对冬小麦产量、品质及旗叶部分生理指标的影响
Effects of Chemical Control on Yield,Quality and Physiological Traits of Winter Wheat
摘要
Abstract
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.关键词
