垄向区田是雨季前在6°以下缓坡地的垄沟中修筑土垱，将长长的垄沟截成许多小浅穴，以土垱拦截雨水，以浅穴暂时贮存雨水，直到雨水慢慢地渗入士壤。垄向区田是最接近水土保持原则的措施--把每一滴降雨保留在它降落的地方，可以较好地解决强降雨和土壤弱入渗的矛盾，能给急雨留 Ridge to the district before the rainy season in 6 degrees below the gentle slope of the ditch in the construction of soil 垱, the long ditch cut into many small shallow hole to soil 垱 interception rainwater to shallow storage of temporary storage of water until the rain slowly infiltration Citizens. Ridge to the area is the closest to the principle of soil and water conservation measures - to keep every drop of rainfall where it landed, which can be a better solution to the contradiction between strong rainfall and weak soil infiltration, rain can give a left
