Abstract:

The research aimed to confirm photosynthetic rate and yield in different maize/chili pepper intercropping system. The stripes in maize and chili pepper in intercropping system was P/M2:3, P/M2:5, P/M2: 7. In maize and chili pepper in intercropping system of 2:3, 2:5, 2:7, the photosythetic rate of maize intercropping were higher than sole maize, sole chili pepper and chili pepper intercropping. And compared to sole chili pepper, the photosythetic of chili pepper intercropping was a 6.78%-20.4% decline; In the three intercropping system, the yield was higher than sole maize and sole chili pepper, reached very significant level (P <0.01). When compared to maize and chili pepper in the monoculture, the intercropping of 2:3 increased 84.7. The best output effect was the intercropping of 2:5.
