摘　　要：经试验检测，稻草覆盖免耕栽培马铃薯收获后，残留在土壤中的有效养分氮、磷、钾大大增加，唯有有机质降低。试验表明，稻草覆盖免耕栽培马铃薯不会吃瘦田，还可以培肥地力。冬种马铃薯每667m^2产量2000kg左右，每667m^2施（13—8—24）三元复合肥60-65kg，农家肥600-700kg为宜。By means of soil test, the remained nutrients in the soil will increase greatly after the harvest of potato No-tillage cultivation with straw-covered but organic matter will decrease. It shows that this technology will enhance the soil fertility. The suitable application amounts of Winter potato with yield of 2000 kg/667m^2 will be compound fertilizer of 60-65kg/667m^2 and manure of 600-700kg/667m^2.
