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。
Through the research on the technology of high yield and water saving of wheat and corn, a water-saving plan was put forward to make the water and water use a reasonable connection. It is considered that the lower limit of water consumption of high-yield wheat is 5250 ~ 6600 m ha per hectare and the lower limit of water consumption of high-yield corn is 6000 m ha per hectare. Reasonable convergence of wheat and corn moisture can save 3000 m m irrigation per hectare throughout the year, saving 3 Secondary watering, which not only ensures the high yield of wheat and corn, but also saves water, is very important for expanding the area of high yield field.
