摘　　要：比较了水育秧移栽、旱育秧移栽、软盘旱育秧移栽、旱育秧抛秧、软盘育秧抛秧、点播和撒播等7种栽培方式对超级早稻产量的效应,结果表明,各栽培方式间根系性状差异明显,其中优势表现较明显的是旱育秧移栽和点播处理;各栽培方式间产量差异显著,呈现移栽>抛秧与点播>撒播处理的趋势;栽培方式间结实率与千粒重差异很小,产量差异主要由有效穗数和每穗粒数的差异造成。The effects of seven cultivation methods（transplanting seedlings raised in wet-land,transplanting seedlings raised in dry-land,transplanting seedlings raised in dry soft-basin,throwing seedlings raised in dry-land,throwing seedlings raised in soft-basin,spot seeding and broadcast sowing） on yield of super early rice were compared with each other.The results showed that the difference of root traits among each cultivation method was obvious,in which the methods of transplanting seedlings raised in dry-land and spot seeding had significant advantage;the difference of yield among each cultivation method was obvious,which showed a tendency of transplanting seedling throwing and spot seedingbroadcast sowing;the differences of setting percentage and 1000-grain weight among each cultivation method were small,and the difference of yield mainly caused by differences of effective panicles and grains per panicle.
