摘要
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。
Soil moisture conservation is the key conponent for water saving research. An experiment was conducted to evaluate different measures on soil moisture storage. The results showed: with plastic mulching, winter wheat yield and water use efficiency were the highest, 38.3% higher than check. But the materials cost was also high. Good result was achieved with corn straw mulching, which was easy to get and with a low cost. There was no difference between spraying BAT and check.
