3种间作套种模式对朝天椒田间生态及产量的影响

Effects of Three Interplanting Patterns on Field Ecology and Yield of Red Pepper

采用大田试验对小麦—辣椒、玉米—辣椒、小麦—玉米—辣椒这3种间作套种模式下朝天椒(Cap-sicum annuum var.conoides)的田间生态和产量进行了调查。结果表明,与朝天椒单作模式相比,间作套种模式可降低田间土壤的根际温度、提高相对湿度、减少光照度。朝天椒的病毒病和疫病病株率、害虫蛀果率均显著降低,产量和产值升高。3种间作套种模式中,小麦—玉米—辣椒模式产值最高。

The effects of three interplanting patterns,wheat red pepper,corn red pepper and wheat,corn red pepper,on field ecology and yield of red pepper Capsicum annuum var.conoides were studied through field experiment.The results showed that compared with monoculture of red pepper,interplanting patterns could reduce the soil rhizosphere temperature and light intensity while enhance the relative humidity.The incidence of viral disease plants,epidemic disease plants and pests bored fruits was significantly reduced;while the yield and output value increased very significantly.Among the three interplanting pattern,wheat,corn red pepper pattern had the highest output value.
