摘　　要：分析了水育秧、旱育秧和淤泥育秧 3种方式对机插秧苗素质的影响。结果表明 :旱育秧更有利于机插健壮秧形成 ,同时在增加秧龄弹性、延长秧龄方面也具有明显的优势 ;淤泥育秧有一定的可行性 ,但成秧率较低 ,且受土壤质地影响较大 ,实际生产中要慎重使用。在培育机插长秧龄秧苗过程中 。The experiments were conducted to investigate the effects of different seedling raising methods,including paddy raised,dryland raised and silt raised seedling,on seedling quality under mechanized transplanting.The results showed that dryland raised seedling was more favorable for growing vigorous seedlings,and had marked advantage to prolong the seedling age.Silt raised seedling method had lower seedling rate compared with dryland raised seedling,although it was feasible to some extent in the practice. Fertilizer should be cut down or removed during long age seedling raising for mechanical transplanting rice.
