丘陵山区坡耕地,水土流失严重,粮食产量很低。如修建水平梯田,工程量大,用工多,在地多人少的贫困山区很难全部实现。为大面积提高旱坡地粮食产量,现介绍一种简便易搞的“蓄水聚肥耕作法”:1、翻土修埂。从坡地下方开始,把距埂30厘米宽、12—15厘米深的表土铲在里边,再挖取18—21厘米深的生土加到地埂上,并踩实拍光,形成30厘 Hilly and mountainous slopes of cultivated land, soil erosion is serious, the grain yield is very low. Such as the construction of terraced fields, large quantities of work, more labor, fewer places more people in poor mountain areas is difficult to achieve. For a large area to improve food production in drylands, is now introduced a simple and easy “water poly-farming practices”: 1, soil repair Xuan. From the bottom of the slope, the topsoil 30 cm wide and 12-15 cm deep from 铲 is shoveled inside, then a 18-21 centimeter deep raw soil is added to the ground 并 and light is applied to form a 30%
