摘  要:
为建立砀山县砀山辣椒施肥指标体系,通过对氮肥不同施用量对产量与质量效果对比分析,依据偏导理论,对回归试验结果进行分析,求出砀山辣椒的最佳效益施肥量为纯氮20.5 kg/667 m2,对应最佳产量3 510.2 kg/667 m2。

摘  要:
According to the partial derivative theory,we analyzed the relationship between the total amount of nitrogen fertilizer and pepper yield,in order to establish the index system of fertilizer application for Dangshan pepper.Based on analyzing the results of the regression test,we found out that the application amount of pure nitrogen was 20.5 kg/667 m2for obtaining the optimum benefit,and the corresponding best yield was 3 510.2 kg/667 m2.
