我省西山地区水土流失严重,土壤瘠薄,产量低而不稳。如何解决这一问题?中阳县赵家山等大队通过几年的生产实践,证明丰产沟种植法是一种能在旱梯田和坡地上蓄水、保土、抗旱、高产的有效途径。1978年,赵家山大队共试验了5亩,3.5亩玉米亩产1,290.4斤,比相同条件下的一般耕作田亩产617.4斤增产109％;1.5亩高粱亩产1‘442斤,比对照亩产624斤增产131％。1979年试验面积又扩大到153亩,种植玉米、高粱、谷子,平均亩产958.7斤,比对照平均 Xishan area of ​​our province has serious soil erosion, infertile soil, low yield and instability. How to solve this problem? Zhao Yang and other brigade in Zhongyang County, through several years of production practice, proven Fengzhuogou planting method is an effective way to water storage, soil conservation, drought, high yield in the dry terraces and slopes. In 1978, Zhao Jiashan brigade tested a total of 5 acres, 3.5 acres of corn per mu 1,290.4 pounds, 617.4 pounds more than the same conditions of general farming yield 109%; 1.5 acres of sorghum mu produce 1’442 pounds, compared with the control of mu yield 624 Jinsheng yield 131%. 1979 test area and expanded to 153 acres, planting corn, sorghum, millet, the average yield 958.7 kg, compared with the control average
