Abstract
The aim was to find out the suitable sowing date and planting density of the new wheat varietyChanghang No. 1in Weibei area. [Method]The two factors and two D saturation optimum design was used to study the yield of the new wheat varietyChanghang No. 1in Hanyuan Area of Weibei under different sowing date and planting density,to establish the mathematics model between sowing date,planting density and yield. [Result]If the goal yield was 6 300- 6 750 kg /hm2,the most suitable sowing period was from September20 to October 1,and the most suitable planting density was 282 × 104- 375 × 104plants/ hm2. [Conclusion]The study provides a theoretical basis for promotingChanghang No. 1and making it reach high yield in Hanyuan Area of Webei.
