The Effects of Different Cultivation Modes on Maize Yield and Soil Water under Deficit Irrigation

The effects of different cultivation modes on soil water,maize yield and yield components under deficit irrigation were studied.The results showed that the ridge side of the whole film cultivation,furrow of whole film,the double ridge pattern of the whole film could significantly improve the content of soil moisture in 0～10cm soil layer.Compared to those in other treatments,soil moisture in different maize growth periods(except the heading stage)was higher.Water consumption intensity of seeding stage～big trumpet stage was lower,but maize yield(17 153.91kg/hm2)and WUE(37.59kg/(hm2.mm))were higher under the whole film furrow.So it has a significant water-saving effect under the whole film furrow.
