中文摘要	在甘肃省半干旱山区黄绵土新修梯田上进行了施肥效应试验研究,结果表明:有机肥与氮、磷、钾肥配合施用是提高新修梯田土壤肥力和农作物产量水平的重要农艺措施,可使作物产量提高21.4%~41.6%,纯收入增加283.0~2 557.2元/hm2,地上部分吸收纯氮、五氧化二磷、氧化钾量分别提高52.8%~70.1%、115.0%~116.7%、16.8%~92.7%,土壤水分利用率提高32.5%~37.1%,耕层土壤速效养分含量亦得到大幅度提高。
英文摘要	The experiment was carried out on fertilization and soil fertility of Loessial soil of newly-built terrace in semi-arid mountain areas in Gansu Provice.The results showed that cooperative application of organic fertilizer,nitrogen,phosphorus and potassium was an important agronomic measure to increase soil fertility and crops’ yield of newly-built terrace.It could increase the crop yield by 21.4%～41.6%,the economical net income by 283.0～2 557.2 yuan/hm2,and the absorption of N,P2O5 and K2O above ground by 52.8%～70.1%,115.0%～116.7% and 16.8%～92.7%,respectively.The utility of soil water was enhanced by 32.5%～37.1%,the topsoil available nutrients content were greatly improved.
