| Abstract: | 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 m 2 for obtaining the optimum benefit, and the corresponding best yield was 3 510.2 kg/667 m2. |
