| 摘 要： | 以特大茄门甜椒、特选牛角王、朝天椒3个辣椒品种为试材，在连作3 a的土壤上栽培，研究不同品种抗连作障碍的效果。结果表明，连作土壤对辣椒株高、茎粗、地上部鲜质量、根鲜质量、叶面积、叶绿素含量以及产量有抑制作用。3个品种中以特选牛角王抗连作障碍能力较强，单株产量减少2.45 %，朝天椒抗性最差，单株产量减少14.8 %。特大茄门甜椒抗性居中。

| Abstract: | In this study,three pepper varieties:‘Qiemen’sweet pepper,‘Niujiaowang’pepper and red cluster pepper were taken as experimental materials and cultivated in the soil for three continuous years to study their effects of preventing continuous cropping obstacle.The results indicated that soil with continuous cropping restrained pepper plant height,stem diameter,fresh weight of over-ground part and roots,leaf area,chlorophyll content and yields.Of the three varieties‘Niujiaowang’pepper had the strongest resistance to continuous cropping obstacle with 2.45 % yield decrease per plant.The resistance of red cluster pepper was the weakest with 14.8 % yield decrease per plant,and‘Qiemen’sweet pepper resistance was between them. |
