2、法】以造纸芦苇残渣、牛粪、碳化稻壳农业有机废弃物等作基质,按芦苇残渣占基质25%、35%、45%设3个处理,各处理均添加牛粪、碳化稻壳和泥炭各15%,用蛭石调节至100%;对照处理以水稻土作基质。测定不同育秧基质处理下秧苗农艺性状,基质保水抗旱能力等指标。【结果】不同配比有机废弃物作育秧基质处理的秧苗农艺性状、基质保水抗旱能力等均优于水稻土作基质处理,根系盘结力均比水稻土作基质处理低,更适合水稻工厂化育秧以及机插秧的要求,其中45%芦苇残渣处理秧苗的综合素质最优。【结论】利用有机废弃物配比的育秧基质可代替普通土壤应用于规模化、工厂化水稻育秧。关键词:水稻;有机废弃物基质;机插秧;秧苗素质中
