摘　　要：针对太行山前平原小麦-玉米两熟农田秸秆全量还田后的一系列问题,从配套的土壤耕作施肥技术上进行了试验研究。该研究重点比较了不同耕作方式对作物产量的影响,并探讨了结合秸秆还田不同耕作方式的氮磷钾养分配比的效果对小麦、玉米产量的影响。结果表明:小麦、玉米秸秆还田后,两季作物全年适宜施肥量:N420～480kg hm2、P2O5135～150kg hm2。在秸秆还田加深松的地块应控制磷肥的施用量,钾肥在小麦、玉米秸秆还田地块增产效果不明显。The studies of fertilizer application techniques matching the soil cultivation systems were conduced to solve a series of problems caused by returning whole stalk into the soil for wheat/corn double cropping area in the plain region Taihang-Mountain before. The results of reasonable N-P-K nutrient proportions under the different cultivation systems matching to return the stalk into the soil and their effects on wheat and corn yield were also analysed in this paper. The result indicate that after returning whole stalks into the soil, the fertilization's quantity of two-season crop in one year: N 420～480 kg/hm^2,P_2O_5 135～150 kg/hm^2. In the field of returning stalks into the soil and deep loose the quantity of phosphate fertilizer should be controlled, but kali fertilizer doesn't have effect.
