According to the survey,[link widoczny dla zalogowanych], more than sweet potato intercropping wheat fields planted after wheat grab 30% of the general increase, cutting drying rate increase of 3 percentage points. Flour yield increased by 1 to 2 percentage points. 12 improved the survival rate and drought resistance of sweet potato sweet potato intercropping shade of wheat due to wind, sun and El potato seedlings from wind and high survival rate, before the advent in the late summer, sets planted sweet potato vine into the rejection of the root system has formed to avoid the summer drought affected. 1.3 can be dry species of desert 20 days in advance of the normal harvest.
