不同滴灌量对冬小麦水分利用及品质的影响
Effects of Different Drip Irrigation Amount on Water Use Efficiency and Quality of Winter Wheat
摘要
Abstract
In order to study the effects of different drip irrigation amount on the water use efficiency and quality of winter wheat,a field experiments was conducted with the cultivar of Qingmai 7 in the field.According to different drip irrigation amount and irrigation stage,we set seven treatments in the experiment,which were in turn:no irriga-tion (CK1 ),drip irrigation at jointing stage (W1 ),drip irrigation at jointing stage and filling stage (W2),drip irri-gation at jointing stage,anthesis stage and filling stage (W3),drip irrigation at raising stage,jointing stage,anthesis stage and filling stage (W4),drip irrigation at raising stage,jointing stage,anthesis stage,filling stage and medium-filling stage (W5),and traditional flooding irrigation (CK2)at over winter stage,raising stage,jointing stage and filling stage,respectively.And each time the drip irrigation amount was 30 mm and the flooding irrigation amount was 60 mm.The results indicated that,the treatments W3 and W4 were significantly improved the quality of winter wheat compared to CK1 .Drip irrigation treatments W3 and W4 improve grain bulk weight,flour milling rate,gluten content,SDS sedimentation and so on.The time of stability,viscosity,pasting temperature,extension area of W3 and W4 were higher than other treatments,increased the wheat gluten strength and baking quality.Drip irrigation could also improve yield and economic benefit.With the increase of drip irrigation,the yield and WUE of winter wheat firstly increased and then decreased,and W3 and W4 displayed maximum.Under the present experimental condi-tions,drip irrigation at jointing stage,anthesis stage and filling stage (W3)optimum processing quality indicators, showed good quality milling and baking quality,ensured production while improving water use efficiency.关键词
