保墒措施是节水研究的重要内客。通过对三种不同保墒措施的比较表明:冬小麦以覆膜种植的产量和水分利用率最高,但美中不足是费用较高;玉米整株秸秆覆盖保墒效果明显,且材科来源广、费用低,两垅间以2株玉米秸秆覆盖为宜;喷洒蒸发抑制与对照比较效果不明显。 Moisturizing measures is an important guest of water saving research. The comparison of three different measures of conservation moisture showed that the yield and water use efficiency of winter wheat were the highest, but the cost was high; the effect of whole corn stalk covering soil moisture was obvious, and the source of timber was wide and the cost was low. Between two strains of corn stalks covered with appropriate; spray evaporation inhibition compared with the control effect is not obvious.
