Abstract:
The authors began to primarily study the planting pattern of replanting oil sunflower afterwheat in Huhhot of the middle and western Inner Mongolia in 1999-2001.The results show :the optimum date was about Jun 25th to transplant oil sunflower seedling, expanding leaves was eight, and its height was 40 -50 cm;the optimum variety was Xinkuiza 4, secondary was KWS;the yield per area arrived at 2 820 -3 570 kg/ha in this planting pattern.According to synthesizing cost analysis, this planting pattern could increase economic profit 101.81 % than single wheat planting,63.92 % than single oil sunflower planting.
