以榆糜2号为材料,研究了长城沿线风沙区不同节水种植模式对糜子籽粒产量及水分利用效率的影响。结果表明,节水种植可以有效地提高农田集水与保墒效果,明显提高土壤水分含量,降低糜子全生育期耗水量与耗水强度,其中,双沟覆膜产量达6 927.43 kg/hm2,比对照增产40.00%,其水分利用效率为17.22 kg/(hm2.mm),比对照增加60.19%。双沟覆膜较其他处理可以明显的提高集雨和保墒效果,有利于提高水分利用效率及作物产量。
Taking Yumi 2 as material, the effects of different water-saving planting patterns on grain yield and water use efficiency of millet were studied. The results showed that water-saving planting could effectively improve the effect of water harvesting and soil moisture conservation, significantly increase the soil water content and reduce the water consumption and water consumption intensity during the whole growth period of the barley, of which, the yield of Shuanggou film reached 6 927.43 kg / hm2 Control increased 40.00%, its water use efficiency was 17.22 kg / (hm2.mm), increased by 60.19% compared with the control. Compared with other treatments, Shuanggou film can obviously improve the rain-harvesting and soil moisture conservation, which is beneficial to improve water use efficiency and crop yield.
