| 摘 要： | 采用“3414”试验设计，在高肥力土壤条件下，研究了玉米最佳施肥量。结果表明，在土壤有机质为1．54％和碱解氮98．4mg／kg、有效磷40．5mg／kg的条件下，夏玉米666．7m^2目标产量高于650kg的推荐施肥量为纯N3．79kg，P2O5 2．06kg，K2O 7．47kg，既可减少肥料流失和对地下水的污染，又可提高肥料利用率。

| Abstract: | The optimal fertilizer rate for maize grown in fertile soil was studied by "3414" experimental design.The results showed that the recommended fertilizer rates of N,P2O5 and K were 3.79 kg,2.06 kg and 7.47 kg per 666.7m2 respectively for summer maize to obtain the yield of 650 kg per 666.7m2 in the soil with the organic matter of 1.5%,the alkaline hydrolysis nitrogen of 98.4 mg/kg and the available phosphorus of 40.5 mg/kg.At this fertilizer rate,the runoff amount of fertilizer and its contamination to under... |
