| Abstract: | Effects of water and fertilizer coupling on yield of intercropped wheat and maize and soil water dynamics were studied by the experiments with 3414 optimal regression design.Results indicated that significant difference was found in the yields under different model of water and fertilizer coupling.The yield and water use efficiency(WUE) were highest under 4800m3/hm2irrigation,420kg/hm2 nitrogen and 120kg/hm2phosphorus levels.Nitrogen is the first main yield factor with the second of irrigation water,and the... |
