山东省临沭县,结合本地实际,大力推广应用我所研究成功的“旱农蓄水聚肥改土耕作法”(即丰产沟)新技术,成效显著。临沭县位于沂蒙山区东南部,属低山缓坡丘陵区。耕地土层浅,肥力低,缺乏水浇条件。在全县81.4万亩耕地中,丘陵旱薄地占到82％,小麦平均亩产多年徘徊在100公斤左右。从1982年开始,该县推广应用“丰产沟”新技术,五年累计开挖“丰产沟”
Shandong Province, Linshu, combined with local conditions, vigorously promote the application of my successful research “dry farming water and fertilizer farming and soil improvement practices” (ie, yield and ditch) new technology, with remarkable results. Linshu County is located in the southeast Yimeng Mountain, is a low mountain hilly area. Cultivated land shallow, low fertility, lack of water conditions. Among the 841,000 mu of arable land in the county, 82% are hilly and droughty, and the average yield of wheat hovers around 100 kilograms for many years. From 1982 onwards, the county popularized the application of “new harvesting ditch” technology and accumulated five years of excavation of “high yield ditch”
