【摘要】 采取4种不同矿化度咸水进行农田灌溉模拟试验,结果表明:利用3g/L微咸水农田灌溉可以周年持续进行。在汛期降雨量丰富、有淡水冬灌条件的地区,矿化度4g/L微咸水灌溉也可以周年运行。矿化度6.0g/L以上的咸水不适宜农田灌溉,必须经过淡水、咸水调配后矿化度在4.0g/L以下方可进行农田灌溉。更多还原

【Abstract】 The model experiment adopted brackish water of four different mineralizations for farmland irrigation.3.0 g/L brackish water can irrigate continuously.If flood season rainfall adequate and irrigation whth freshwater in winter in the region, 4.0 g/L brackish water can irrigate continuously.Mineralization more than brackish water 6.0 g/L were not suitable for farmland irrigation, must be blended freshwater with brackish water to mineralization less than 4.0 g/L.更多还原
