Abstract

摘要： 以迟熟中粳武育粳3号为供试材料，研究播种密度、叶龄、壮秧剂、多效唑、营养土配比等处理对武育粳3号秧苗素质的影响。结果表明，随播种密度的增加，武育粳3号秧苗成苗数、叶龄显著增加，苗高、假茎宽、地上部重量、充实度显著下降，每盘3 700~4 000出苗数可较好地兼顾秧苗素质和盘根效果；壮秧剂喷施18 d、22 d后，适宜的壮秧剂浓度对秧苗地上部干重、根系干重、充实度、苗高、叶龄、假茎宽等性状有明显的促进作用；20 mg/kg多效唑在浸种时施用能较好控制秧苗的株高，避免高浓度造成秧苗株高偏低的现象；用J1N8营养土配方（每盘施尿素8 g，腐熟鸡粪与土壤重量比分别为1∶9）培育的秧苗综合素质突出，育秧时间缩短，是在茬口紧、时间短的情况下培育高质量秧苗较为理想的床土培肥方案。
