摘　　要：采用双因素随机区组设计方法,以水稻品种黄华占为试验材料,分析在机插秧栽培模式下,不同的播期、插期组成的四种秧龄组合对产量性状和叶龄发生规律的影响。结果表明,随着播期和插期的推迟,产量水平呈下降趋势,其中以35d为最适秧龄,返青快、产量最高;且随着播期推迟,主茎叶片有减少趋势。Using rice‘Huang Huazhan’as experimental material,we analyzed the effects of different sowing and transplanting stages on yield characters and leaf age occurrence regularity using two-factor random block design method under the mechanical transplanting mode.We examined four seeding age combination and found that as sowing date and interplanting date were delayed,the yield leaves decreased.However,35 days was found to be the most suitable seedling age,with the fastest greening and the highest yield.Furthermore,with the delay of sowing date,the number of leaves on main stem decreased.
