| Abstract: |
| Root growth dynamics in maize/soybean strip intercropping system were investigated through washing roots in soil profile, and root distribution model of the intercropping system was developed.The relationship between root depth and lateral extensional distance and DAS (days after sowing) were fitted with the quadratic curve equation and modified logistic function.Root depth and lateral extensional distance were normalized with the relative depth (RD) and lateral distance (RLD) .The relationship between RLD and RD was fitted with Gauss function.Root distribution could be obtained using the developed root distribution model with DAS. |
