一、以截流天上雨水为主的集雨窖集雨窖主要解决枣树管理用水和枣粮间作作物如花生、红薯用水。利用7～9月的降雨，截流天上雨。选择离水源较远的枣树沟埝阶地坡根修建集雨窖（形似红薯窖）。洞深2～6m以上，洞宽1.5～3m，洞高2～3m，储水量6～50m3以上。洞顶部要比埝阶地表面 First, to intercept the sky rainwater-based rainwater pit set rainwater pit caves mainly to solve jujube management water and jujube grain crops such as peanuts, sweet potato water. Use of rain from July to September, cut off the sky rain. Select far from the water Jujube ditch 埝 terraced slopes to build rain pits (shaped like a sweet potato cellar). Depth of 2 ~ 6m, hole width 1.5 ~ 3m, hole height 2 ~ 3m, water storage 6 ~ 50m3 above. The top of the cave is larger than the ridges of the terraces
