摘　　要：炼芽取代育秧的水稻乳苗抛栽技术,是通过种子处理技术,即在浸种、催芽的基础上增加了炼芽处理,将种子制备成乳苗,直接用于配套的乳苗抛栽,该技术免去了育秧工序,节省了育秧成本,抛秧过程中还具有省工、省力的优点,但与常规手插秧相比有不同程度减产,两年平均减产一期为19.1%、二期为23.6%。The rice nurseling-seedling-scattering was a technology which increase hardening plantlets on soaking seed, accelerating germination basic, then made the seed into nurseling-seedling and could be directly applied to production, it can spare the process of seedling, reduce the seedling cost and labor-saving,but it may cut production which were 19.1%（phase Ⅰ） and 23.6（phase Ⅱ） compared with the general transplanting.
