氮、磷、钾肥料施用对辣椒产量和经济效益的影响

Effect of N, P and K fertilizers application on the yield and economic efficiency of chili

田间试验结果表明,氮肥对朝天椒的增产作用大于磷、钾肥,合适的配施氮、磷、钾增产效果显著,钾素含量较高的土壤栽种朝天椒的最佳施肥配比为N∶P2O5∶K2O=1∶0 4～0 5∶1 0～1 1,钾素含量较低的土壤施肥配比为N∶P2O5∶K2O=1∶0 9∶2时增产增收效益明显。研究结果对辣椒专用复合肥的开发应用、指导辣椒合理施肥等具有重要意义。

This paper deals with the effect of N,P and K fertilizers on the yield and economic efficiency of chili. The results showed that the yield of chili was increased obviously by applying suitable N, P, K fertilizers, of which N fertilizer was the best and the optimum ratio of N∶P_2O_5∶K_2O was 1∶0.4～0.5∶1.0～1.1 for the soils with high K fertility, while the optimum ratio of N∶P_2O_5∶K_2O was 1∶0.9∶2 for the soils with low K fertility. Those results had an important role for producing the compound fertilizer of chili.
