| Abstract: |
| 【Objective】Taking pepper as test material, the optimum proportion of organic fertilizer instead of chemical fertilizer was screened out to provide scientific basis for fertilization in pepper production. 【Method】The agronomic traits, yield and partial productivity of pepper under different fertilizer treatments were investigated, and the mathematical models of fertilizer application amount, yield and partial productivity were established. 【Result】There were significant differences in agronomic traits and yield per plant of pepper under different organic fertilizer substitution treatments. Under the condition of soil fertility in this study, the fertilizer effect equation between pepper yield (Y1), PFP (Y2) and compound fertilizer application rate (X) was obtained (Y1=-0.0324X2+33.936X+65657, Y2=-0.000002X2+0.0018X+2.6682). 【Conclusion】The optimum application amount of compound fertilizer and organic fertilizer was 523.70 kg.hm-2and 31907.41 kg.hm-2, respectively, when the maximum yield of pepper was obtained. The optimum application rate of compound fertilizer and organic fertilizer were 450 kg.hm-2 and 33750 kg.hm-2 respectively when the maximum fertilizer use efficiency (PFP) was obtained. |
