摘要: 采用"3414"试验不完全实施方案,以土壤测试为基础,根据相对产量确定土壤养分含量丰缺,试验结果表明:六盘山东麓黑垆土种植地膜玉米的土壤中氮中等、缺磷、钾丰富,氮、磷、钾合理施肥比例为1.0∶0.5∶0.42,肥料养分利用率氮素为33.7%、磷素为24.9%、钾素为13.1%。

Abstract: Use "3414" test not completely implementation plan.With soil testing as a foundation,according to the relative yield sure soil nutrient content of abundant,the experimental results show that: LiuPanShan foothill black lu to soil plastic-film corn planting soil nitrogen medium,lack of phosphorus,potassium is rich,nitrogen,phosphorus,potassium fertilization 1-0.5-0.42,fertilizer utilization ratio of nutrients.Nitrogen,phosphorus,for 33.7% to 24.9%,and 13.1% for potassium.For corn production to provide the scientific basis for rational fertilization.
