摘要
根据24年肥料效应长期定位监测试验结果,研究了不同施肥处理对作物产量及土壤肥力、养分水平等指标的影响。结果表明,不同施肥处理作物产量差异较大,有机肥和氮、磷、钾化肥的配合施用对提高作物产量、增加土壤养分作用十分明显。
This paper has summarized the results of different fertilizers＇ effectiveness on crop yield and soil fertility since 1992-2005 in Liaoning Province. Results indicated that application of manure and chemical NPK could gratly increase crop yield and soil fertility.
