英文摘要	With the continuous improvement of the mechanization level and the development of new crop varieties, the optimal strip width for intercropping crops is important. In this study, field experiments were conducted to analyze the effects of different row spacings and planting patterns on photosynthesis, chlorophyll fluorescence, and the related enzyme activities of maize ear leaves in a maize-soybean intercropping system using two planting patterns (wide-narrow rows of 80-50 cm and uniform ridges of 65 cm) and two intercropping ratios (four rows of maize and four rows of soybean; six rows of maize and six rows of soybean). The results showed that the pattern of wide-narrow-row spacing significantly improved the photosynthetic capacity of maize compared with the uniform-ridge planting pattern, along with marked elevation in the values of stomatal conductance (Gs), the transpiration rate (Tr), and the photosynthetic rate (Pn). On the other hand, the values of photochemical quenching (qP), actual photochemical efficiency (phi PSII), and maximum photochemical efficiency (Fv/Fm) also significantly increased, and the effect of D-M6S6 treatment was the most significant on these parameters. Similarly, the activities of phosphoenolpyruvate carboxylase and ribulose-1,5-bisphosphate carboxylase/oxygenase also increased significantly. Among different treatments, the yield under the D-M6S6 treatment was the highest. Therefore, based on the planting pattern of the wide-narrow-row spacing, the intercropping of six rows of maize and six rows of soybean is the better design in the semi-arid regions of western China.
