摘　　要：通过水稻育苗盆栽试验,研究了不同有机物料育秧基质对水稻秧苗生长及养分积累的影响。结果表明:(1)COC(玉米秸秆+碳粉)为最优基质处理,该处理的基质是由粉碎玉米秸秆、有机肥、草炭、沸石、蛭石、细河沙、碳粉等按不同配比混合而成,用这种基质的所育水稻苗生长状况最好;(2)不同有机物料育秧基质对水稻苗生长的影响,玉米秸秆好于水稻壳粉,菇渣的效果较差;(3)相同配比的处理间,加碳处理均优于不加碳处理。本研究结果对水稻育苗基质生产中的材料选择提供了理论依据。Effects of different organic materials on rice seedling growth and nutrients accumulation were studied through rice seedling pot experiment. Results showed that： （1） The COC was the optimal substrate, which was mixed in different propor-tions by ground corn stalks, organic manure, peat, zeolite, vermiculite, fine river sand, carbon powder, etc. The quality of rice seedlings cultured on it was the best; （2） Effects of different materials on the growth of rice seedling were that ground corn stalk was better than rice shell powder and mushroom residue effect was poorer; （3） For the rice seeding growth, treat-ment of carbon powder added were better than all the other ones among the treatments of the same ratio. Results of this study would provide a theoretical basis for selecting material of the substrate production of rice seedling.
