玉米膜下滴灌是将滴灌带铺设在膜下,利用水管道将水源送入到滴灌带,在滴灌带上开了一些滴头,让水可以不间断地滴到土壤中,乃至于直接渗透到作物根部。既可以避免水分蒸发,也可以让作物充分吸收水分。这项技术的应用可以有效提高水分和化肥的利用效率,既能减少施肥过量引起的环境污染,也能有效改善农田的生态环境,增加粮食的产量和农民的收入。
Under the drip irrigation, the drip irrigation tape is laid under the membrane, and the water is fed into the drip irrigation belt through the water pipe. Some drops are dripped on the drip irrigation belt, so that the water can be dripped into the soil without interruption, Crop roots. Not only to avoid evaporation of water, but also allow crops to fully absorb moisture. The application of this technology can effectively improve the utilization efficiency of water and fertilizer, not only reduce the environmental pollution caused by over fertilization, but also effectively improve the ecological environment of farmland, increase grain yield and farmers’ income.
