Abstract: In order to achieve the goal of drought-resistance and high rate of germination of sorghum and the application of general precision planter, four kinds of adhesion agent (clay, putty powder, fly ash and slag) and three kinds of adhesive (108 glue, water and gelatin) were selected, a ratio experiment was conducted, the best formula of sorghum seeds pelleting material was screened and compressive strength, disintegration time, the rate of germination and seedling growth of the pelleting seed were assayed. The results showed that the germination rate of clay pelleting seed, putty powder pelleting seed, fly ash pelleting seed and slag pelleting seed was 95%, 85%, 75% and 92% respectively, while the germination rate of the naked seed was 97%. The compressive strength of seed pelleted by gelatin solution was lower than that pelleted by 108 glue solution and the order of compressive strength was clay> putty powder> slag> fly ash; the order of disintegrating degree was: clay> putty powder> fly ash> slag. The compressive strength and disintegrating degree of seeds pelleted by the same adhesive concentration and different fillers were also different, the order of compressive strength was clay> slag> putty powder> fly ash; the order of disintegrating degree was clay> putty powder> fly ash> slag. Therefore, the optimal formula of sorghum seed pelleting was clay and 20% of the 108 glue solution.
