摘要
在云南省丘北辣椒示范区对辣椒．花生、辣椒．大豆和辣椒-玉米间作模式进行调查研究。结果表明，总体上，间作系统中辣椒叶片N、P和K含量均显著高于辣椒单作，其中辣椒-玉米（10：2）间作系统中辣椒叶片N、P和K含量分别比单作增加12．93％、5．17％和22．64％。与辣椒单作相比，辣椒间作显著提高了盛果期辣椒的株高和单株结果数，提高幅度分别为1．57％-20．89％和3．06％-307．52％；有效控制了辣椒病毒病、疫病和烟青虫的发生，控制效果分别达24．01％、6．87％～23．80％和4．31％～36．40％；辣椒间作显著提高了辣椒的生物量和产量，辣椒产量的增幅为9．73％-53．52％，起到了明显的增产、增值效果。初步筛选出的辣椒-花生（15：5）、辣椒-大豆（8：2）和辣椒．玉米（10：2）三种辣椒间作模式供进一步生产示范。
The three chilli pepper intercropping system, including chilli pepper-peanut, chilli pepper-soybean and chilli pepper-maize, were studied in chilli pepper demonstration area of Qiubei County,Yunnan Province. The results showed that chilli pepper intercropping system increased the contents of N, P and K in chilli pepper leaves,in general. Chilli pepper-maize intercropping system increased the contents of N, P and K in chilli pepper leaves by 12.93%, 5.17% and 22.64%, respectively. Comparing to monocultures, the chilli pepper intercropping system increased plant height and fruit amounts significantly, the increases were detected ranging from 1.57% - 20.89% and 3.06% - 507.52% , respectively. Control effect on mosaic virus, phytophthora blight and tobacco budworm in chilli pepper ripening period were also obvious, which were detected ranging from 24.01%, 6. 87% -23.80% and 4. 31% -36.40% , respectively. Biomass and yield of chilli pepper were also increased significantly in chilli pepper intercropping system,chilli pepper yield in the same area were detected ranging from 9.73% -53.52%. Based on study on the three chilli pepper intercropping pattern, chilli pepper-peanut （15：5） , chilli pepper-soybean （8： 2） and chilli pepper-maize （10：2）, will be used for large scale production and demonstration in the future.
