Abstract: Wheat-rice rotation is an important planting pattern in Xiangyang city. In order to solve the outstanding problems of low sowing, seedling quality and yield of rice-stubble wheat in this region, “zefeng 2BMF-12” no-tillage half-tillage seeder was introduced from Sichuan province to Xiangyang city through China agriculture research system in 2017. After continuous improvement of technology, the sowing quality and yield have been significantly improved. The experiment results showed that the seed exposing rate and ridge-breaking length of the no-tillage half-tillage strip planting method reduced by 79.3% and 83.3%, which compared with the conventional tillage sowing method during 2017 to 2018. Many demonstration pieces increased yield by 11.0%~13.2%, saving cost and increasing efficiency by 2 241.90 yuan per hectare on average.

Key words: planting pattern, wheat-rice rotation, half-tillage strip, adaptability, Xiangyang city
