| Abstract: | The results of the experiment in Hetao irrigated regions of Dengkou in 2009—2010 show that in the pattern of stereo planting of Wheat-Corn relay intercropping and Wheat-Sunflower relay intercropping,the daily average water requirement in growth period of wheat,plastic-film Corn,none plastic-film Corn and sunflower are respectively 4.31 mm,4.43 mm,4.39 mm,3.42 mm.Through analyzing monitoring data by Bowen-Ratio System and ET0 determined by various methods,the Penman-Monteith method recommended by FAO-56 and the Irmark-Allen fitting method accord with local reality.The research shows that the pattern the of Wheat and none plastic-film Corn relay intercropping predominate in biological yield in above three stereo planting pattern and when the yield of Wheat is rising,one of plastic-film Corn is falling.The economic coefficient of the alternative irrigation mode of 52 mm and 97 mm is superior.It is visible that timely water compensation for oil crop undergoing water deficit can improve economic coefficient. |
