摘　　要：笔者对3种辣椒谷子间作模式在辣椒不同生长期对辣椒白粉病和日灼病的防控作用进行了研究。结果表明,3种辣椒谷子间作模式对辣椒白粉病的防效为22.63%~61.03%,对辣椒日灼病的防效为54.73%~76.63%。其中,2垄(4行)辣椒垄间间作1行谷子(P4M1)和3垄(6行)辣椒垄间间作1行谷子(P6M1)两种模式的防效与对照5垄(10行)辣椒间作1垄(2行)玉米(P10C2)相当;同一模式对白粉病的防控效果在辣椒生长后期随白粉病病情的加重而降低,在辣椒生长中期对日灼病的防治效果略高于生长后期。综合考虑间作存在的多种影响因素,建议对P6M1模式进行防控机理研究和生产应用。The effects of three millet-pepper intercropping patterns on the control of two pepper diseases,pepper powdery mildew and sunscald,were studied in different growing periods.The results showed that three millet-pepper intercropping patterns had control effects on pepper powdery mildew and sunscald,and the control effects to them were between 22.63%to 61.03%and between 54.73%to 76.63%,respectively.The patterns of P4M1 and P6M1 showed similar control effects compared with the maize-pepper intercropping control P10C2.As the severity of pepper powdery mildew increased in the late stage of pepper growth,the control effect of the same pattern on the disease decreased.Considering various influencing factors of intercropping,we suggest conducting mechanism research and field application on the pattern of P6M1 in the future.
