| 中文摘要: |
| 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。 |
| 英文摘要: |
| The strain of Yumi 2 was used as a material to study the grain yield and water use efficiency of proso mil-
let under different water saving treatments in standstorm area along the Great Wall . The results show that the water saving ways may improve field catchment and water retention, increase soil water content，reduce water consumption amount and water consumption intensity. The grain yield of proso millet with film mulching on ridge and double furrows was largest， reaching 6 927.43 kg/hm2 and increasing by 40% compared to CK，while its water use efficiency was 17.22 kg/ (hm2·mm)，increasing by 60.19%. Film mulching on ridge and double furrowss may improve field catchment and water reten-tion，and increase grain yield and water use efficiency. |
