摘　　要：在辽宁西部早春温室大棚条件下,以北方粳型超级稻辽粳399为参试品种,探讨了不同育秧基质与秧盘组合处理对机插稻秧苗素质及产量的影响。结果表明,与采用客土作育秧基质相比,其他3种育秧基质均具有提升秧苗素质的作用;与对照(客土+盒式秧盘)相比,其他7个组合处理下的秧苗素质更好,且运输更加方便,移栽根系损伤轻、缓苗时间短,并以M2K2组合处理(有机育苗基质+钵形毯状秧盘)表现最优,产量也最高,比对照增产11.91%。Under the conditions of greenhouse in early spring in western Liaoning,the effects of different seedling raising matrix and seedling trays on seedling quality and yield of mechanical transplanting rice were studied,using Liaogeng 399 as the test variety.The results indicated that compared with using soil as seedling raising matrix,the other three kinds of seedling raising matrix could improve the quality of seedlings.Compared with CK(soil+box tray),the seedling quality of the other treatments were better,the transportation was more convenient,the damage of root system was light,and the time of seedling recovery after transplanting was shorter.The combination of M2 K2(organic seedling raising matrix+pot blanket seedling tray)showed the best performance and the highest yield,the yield increased by 11.91%compared with CK.
