延安地区有坡耕地320余万亩,其中水平梯田87万亩,草田轮作为数甚少,大部分坡耕地水土流失严重。1975年,地区提出粮、灌、草带状耕作。时近10年,已在各地开花。延长赵家河乡草田带状轮作、延安市碾庄乡双田、大田村山地果园紫穗槐与果树条带间作、李渠乡王庄村80亩坡耕地粮灌草带状耕作、子长县涧峪岔乡毛家河村隔坡梯田桑粮间作、果粮间作、林草间作、安塞县水保实验区千亩山地粮灌草间作等均取得了显著的效果。
There are over 320 million mu of sloping farmland in Yan’an, of which 87 million are terraced fields, with a small number of grassland spreaders. Most of the sloping farmland is seriously affected by soil and water loss. In 1975, the region proposed grain, irrigation, grass belt farming. Nearly 10 years have flowered everywhere. Extension of Zhaojiahe Township grassland strip rotation, Yan’an City grinding village double field, Tamura mountain orchard Amorphophallus and fruit tree strip intercropping, Liqun Township Wang Zhuangcun 80 acres of slope farmland grain shrub herbaceous strip farming, Zi Changxian Jian valley Chaxiang Township Maojiahe separated slope terrace mulberry grain intercropping, fruit intercropping, intercropping forest and grass, Ansai County Soil and Water Conservation Experimental Area Qianmu mountain shrubs and intercropping have achieved remarkable results.
