为探索石灰性田N的投入量对大肉包心芥菜产量的影响，进行了不同施N量的效益比较试验。试验结果表明，通过回归分析，建立大肉包心芥菜产量（Y）与N施用量（X）的肥料效应函数模型为Y=469.45+434.292 X-7.6918 X2，确定广西钟山石灰性田667 m2经济最佳施氮量为27.88 kg，经济最佳产量为6598.71 kg，比N0不施N处理667 m2增产6148.51 kg，增收5997.12元，产投比为40.6。

In the pepper, we studied the effects of different amounts of N fertilizer on the yield and benefit of leaf mustard in calcareous soil to obtain the optimum benefit. The results showed that, based on the regression analysis, we built the fertilizer effect function model between yield of leaf mustard (Y) and application amount of N fertilizer (X), and the model was Y=469.45+434.292 X-7.691 8 X2. According to the model, we determined that the optimum benefit was 5 997.12 Yuan/667 m2, and the best application amount of N fertilizer was 27.88 kg/667 m2. While we obtained the optimum benefit, the leaf mustard’s yield was 6 598.71 kg/667 m2, which was increased by 6 148.51 kg/667 m2 than that of the nitrogen-free treatment, and the input-output ratio was 40.6.
