| Abstract: |
| The study aims to investigate the dry matter accumulation and yield components of maize cultivar Xianyu 335 and sorghum cultivar Shenza 5 under Jujube-cereal intercropping. The net photosynthetic rate, dry matter accumulation, yield components, plant height and stem diameter were measured on 45, 60, 75, 90 d and 105 d after germination. The highest yield of maize and sorghum were detected for ZY4 and ZG8 pattern, respectively. Generally, the net photosynthetic rate of sorghum were higher than that of maize during growth periods; however, the net photosynthetic rate of sorghum had little difference in different growth periods, indicating the necessity of proper row space between sorghum and maize. Average rate of dry matter accumulation of maize and sorghum were higher in ZY4 and ZG8 pattern, underlying the foundation of high yield formation. Meanwhile, the density greatly affected spike/ear number and grain weight, but slightly affected grain number. In addition, ZY4 and ZG8 showed better intercropping effect for jujube, maize and sorghum. |
