摘　　要：[目的]研究育秧基质对水稻秧苗素质的影响。[方法]以镇稻99为材料,采用自然土、营养土和有机育秧基质进行秧盘育秧,研究育秧基质氮素的释放情况以及基质对秧苗素质的影响。[结果]培肥度最高的有机基质处理秧苗生长速度快、植株高大;培肥度适宜的营养土处理秧苗健壮、根系性状好。育秧基质有效氮素的释放和供应强度均随其培肥程度的提高而提高。[结论]营养土和有机基质育秧符合水稻机插秧苗的壮苗要求,有机基质育秧应适当控制秧苗的生长并及时栽插。[Objective] The aim was to study effect of different substrates on qualities in rice transplanting.[Method] With the seedlings of Zhendao 99 as materials,natural soil,nutrition soil and organic substrates were adopted to study seedling qualities and nitrogen release character in different substrates.[Results] Organic substrate can make seedling grow faster and higher,nutrition soil can make seedling stronger and its root characteristics better.Available nitrogen release and supply intensity of substrates were increased with fertility betterment improved.[Conclusion] Nutrition soil and organic substrate were perfect seedling substrates,and seedling growth in organic substrate should be controlled properly and transplanted in time.
