| Abstract: | Objective] To research the effects of seedling age and sowing rate on seedling quality and yield of mechanical transplanting rice.Method] With high-quality Japonica rice variety Nanjing 46 as the research material,we researched the effects of seedling age and sowing rate on the seedling height,leaf age,survival seedling rate,seedling number,quality,tiller dynamic,yield and its component factor.Result] Seedling age and sowing rate showed significantly impacts on the seedling quality and yield of mechanical transplanting rice.Among them,20 d seedling age and 80 g/plate sowing rate had the optimal seedling quality;and its actual yield was the highest,which was 10 263.45 kg/hm2.Conclusion]This research provides theoretical foundation for the further improvement of rice mechanical transplanting technology,and for the acceleration of rice mechanization transplanting development. |
