Abstract: The Field experiments were counducted to research the growth characteristics and high yield cultivation techniques of rice with nutrition bowl mechanical transplanting in Fengtai, Baohe, Baihu and Lujiang of Anhui Province form 2011 to 2014, with conventional japonica rice, hybrid japonica rice and hybrid indica rice as materials.The results showed that bowl seedling mechanical- transplanting has the significant advantages of lower sowing quantity, stronger seedling quality, higher seedling flexibility, faster re-green ability, earlier tillering, stable population culm and tiller dynamics, higher tiller percentage, and appropriate yield components, comparing with blanket seedling mechanical-transplanting. Meanwhile, the spikelets per panicle and population total spikelets under the bowl mechanical transplanting were significantly increased. On the basis of this research, the key high yield cultivation technique of rice with bowl seedling mechanical-transplanting was quantified. It provided a good theoretical and practical basis for researching new model of rice planting mechanization, improving the combination of agricultural machinery and agronomy technology and accelerating the progress of mechanical transplanting in Anhui Province.
