Experimental Study on the Soil Water Dynamics and Growth Effect of Winter Wheat in Furrow Irrigation Mode

This paper reported a study on the soil water dynamics and growth development of winter wheat under treatments of different furrow irrigations.The results showed that the soil water dynamics and growth development were similar under different irrigation treatments before the jointing stage.After the jointing stage,with the increasing of irrigation amount,the soil water content under furrow irrigation was 11.6% higher than that under border irrigation,and both leaf area index(LAI) and ground dry matter increased by 11.4%and 39.73% under furrow irrigation than those under border irrigation,respectively.However,plant height was lower under furrow irrigation than those under border irrigation.Comparing with the flat irrigation mode,the irrigation amount saved by 40%,the production increased by 7.66%,and efficiency of water use increased by 0.28 kg/m3 under furrow irrigation,which achieved the goals of water-saving and high yield.Based on the data in this study,the best experiment scenario was the three times irrigation under the furrow irrigation and ridge planting.
