| 摘 要： | 目的]大面积改善土壤生态环境，提高木薯单产及品质。方法]利用水分（雨水）控制技术，研究了不同土壤耕作生态类型对木薯生理生长及环境的影响。结果]与降雨内涝淹水处理相比，降雨时正常排灌疏松土壤的含水量增加44．23％，容重降低17．32％，孔隙度增加38．26％，微生物菌落总数增加384．67％，水分利用效率提高22．65％，光合效率增加55．28％，水、土流失量分剐减少83．70％和125．29％，这诸多因素构成了良好的土壤耕作生态。木薯产量达到46800kg／hm^2；反之，降雨短时渍水处理、降雨内涝淹水处理．因其土壤耕作生态不良，其产量分别为19125、6225kg／hm^2。结论]在合理利用天然降雨、不渍水不淹水而保持良好的土壤耕作生态条件下，木薯种植容易获得高产。
