| Under the field condition, the photosynthetic characters, yield and quality of peanut were studied in three treatments, including mono-cropped peanut (CK), equal row cassava-peanut intercropping (T1), wide and narrow row cassava-peanut intercropping (T2). The results showed that the partial land equivalent ratio of peanut (PLER-P) in T1 and T2 was 0.34, which was greater than the peanut area ratio of cassava-peanut intercropping system (F=0.25) by 36.0%, indicating that the peanut pod yield in intercropping mode was greater than that in monocropping mode, in the same planting area. Compared to the T1 treatment, the leaves area per plant and net photosynthetic rate in seeding and maturity stage in T2 treatment promoted, and chlorophyll content, 100-pod weight and 100-kernel weight of peanut improved. The result indicates that T2 treatment has more advantage than T1 treatment, we can apply wide and narrow row cassavapeanut intercropping mode in cassava intercropping. |
