| Abstract: | By adopting effective measures, such as drip irrigation, reasonable irrigation amount, fertilizing at special growing stages on needed, united application of water and fertilizers, suitable combinations of nitrogen(N) and phosphorus(P 2O 5), and applying N and P 2O 5 at rates of 168.0～186.0 kg/hm 2 and 132.0～159.0 kg/hm 2 respectively in entire corn season, yield of summer corn interplanted in fallow strips in winter wheat field has reached more than 9450.0 kg/hm 2, and water use efficiency over 1.9 kg/m 3. The effective measures can result in obvious effects of water saving and yield raising. |
