摘　　要：扬黄新灌区土壤基础肥力很低,通过重施化肥,可在2 ～3 年内使农作物产量和土壤肥力养分指标达到中上水平。化肥配施有机物质秸秆或农家肥,效果更快更好。重施化肥,无机有机结合,是新灌区农业实现快速起步、持续发展的根本途径和措施。The original fertcility of the soil in New Yellow River Pumping Irrigation Area is very low. Howevwr, by applxing fertilizer in a lange rate the indicators of the soil fertility and nutrient and crop yierd were upgraded to middle and upper level in 2～3years. The effect was better and came faster when fertilizer was applied together with organic substance auch as straw or farmyard manure. aApplication of fertilizer in large rate and combination of inorganic fertilizer with organic manure are the key approaches and measures for the agricultural production in the New Yellow River Pumping Irrigation Area to achieve rapid starting and sustainable development.

关 键 词：扬黄新灌区 重施化肥 无机有机结合 持续发展
