Eco-physiological characteristics of winter wheat-corn intercropping systems under rainfall catchment and supplementary irrigation
|
Abstract:
The field experiments show that supplementary irrigation can enhance the difference between the temperatures of leaf and atmosphere. The average photosynthesis rate of intercropped wheat and corn can be improved by 2 77% and 24 85% respectively than that of single planting in the whole growth stage, and it is positively correlated to the yield. Supplementary irrigation in critical stages can enhance the relative humidity in the canopy, and improve the photosynthesis rate and yield.
