Abstract:

The four different direction ridges which indicate different illumination intensity. East-west Ridge, South-north Ridge, South-east Ridge and South-west Ridge were designed in this experiment. Effect of different illumination intensity on Ridge temperature, furrow temperature, water content of soil and yields of maize were analyzed. Effect of different illumination intensities on Ridge temperature showed that South-north Ridge > East-west Ridge > South-east Ridge > South-west Ridge. Effect of different illumination intensity on furrow temperature showed that South-east Ridge > South-north Ridge > East-west Ridge > South-west Ridge. Effect of different illumination intensity on water content of soil showed that South-north Ridge > South-east Ridge > East-west Ridge > South-west Ridge. Effect of different illumination intensity on yields showed that South-west Ridge > South-north Ridge > East-west Ridge > South-east Ridge. But all results didn’t show significance level of difference in different disposes, this suggested that cultivation pattern of Different Direction Ridges was not important factor for soil physical properties and yields.
