摘要
通过对小麦玉米高产节水配套技术研 究, 建立了以 底墒水一水 两用合理衔 接的水分运 筹方案。认为高产小麦耗水量的下限为每公顷5250 ~6600 m m , 高产玉米耗水量下 限为每公顷 6000 m m , 小麦、玉米水分合理衔接,全年每公顷可节省3000 m m 灌水量,可节省3 次浇水,这既保证了小麦玉米高产,又节约了用水,对于扩大高产田的面积极为重要。
The conveyance technology of water - saving irrigation have been studied in high - yieldgrain and established the schem e of w heat and m aize that soil m ositure w ater can be utilizated in dualpurpose and reasonable dovetail . The m axim u m w ater consu m ption of high yield is 5250 ~6600 m m inper hectare w heat and 6000 m m in per hectare maize . The water of w heat and m aize can be utilizated inreasonable dovetail ,the irrigation content can be saved 3000 m m per hectare ,and decreased 3 times ir rigation . This sche m e will guarantee high yield in grain and save w ater consu m ption ,and have im por tant effect to expand the area of high - yield grain .
