【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。更多还原

【Abstract】 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 proportions 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,treatment 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.更多还原
