不同畦灌方式对冬小麦土壤水分和水分利用效率的影响
Effect of different border irrigation mode to the soil water and water using efficiency of winter wheat
摘要
Abstract
Field experiment of border irrigation was conducted , have researched the water requirement of winter wheat during the major growing periods ,and analyzed the effect of different border irrigation methods to the soil water and water use efficiency of winter wheat ,evaluated the irrigation quality and the benefits under different treatment of border irrigation .The results indicated that :The maximal water requirement was at the filling stage of winter wheat .In contrast with the flood irrigation treatment (as CK ) ,the irrigation uniformity and irrigation efficiency of winter wheat by the bor-der irrigation with the plot of 30 m × 3 m was the highest ,reached 93 .33% and 84 .46% ,respectively .The water con-sumtion was decreased 5 .96% ,the yield was increased 25 .03% ,water use efficiency was increased 33 .24% ,and the added profit was 1561 .61 yuan·hm-2 .Therefore ,according to the local production situation of the winter wheat bound-ary irrigation area ,the appropriate border irrigation method was recommended that the inflow rate per unit width and bor-der width and length are 5 L·m-1·s-1 ,3 m and 30 m.关键词
