【摘要】 在内蒙古西部半干旱地区,通过边际分析原理,提出在水源充足条件下的最优灌溉方案;在水源不足的情况下确定出单位面最优供水量及相应的灌溉方案。单位面积最优灌溉方案既不同于丰产灌溉定额,又不同于以每立方米水效益最大来确定单位面积供水量,而是介于二者之间。更多还原

【Abstract】 The optimum Scheme of Sugarbeet irrigation system in the suffic- ient water condition is raised using the forden analysis principle in western inner mongolia semi-dry region and also the optimum content of water supply and correspondent irrigation system is proposed in the deficient water condition. The optimum irrigation scheme is not same as the high yield irrigation scheme and is not the same as the content of water supply per unit area based on biggest benefit of the per cubic meter of water and it is just between the optimum irrigation scheme and content of water supply.更多还原
