摘　　要：以大穗型品种Y两优900和穗粒兼顾型品种徽两优996为试验材料,研究不同秧龄、播种量和株距配置对杂交中籼稻钵苗机插栽培条件下产量的影响。结果表明:2种类型杂交中籼稻品种钵苗育秧适宜的播种量均以2~3粒/钵为宜,大穗型杂交中籼稻品种的适宜秧龄和株距配置分比为20~25d、15.7~20.7cm,穗粒兼顾型品种的适宜秧龄和株距分比为25~30d、12.4~15.7cm。The large-spike variety Y Liangyou 900 and the panicle-grain variety Huiliangyou 996 were used as experimental materialsto study the effects of different seedling age,sowing amount and plant spacing on the yield of hybrid medium indica rice seedlings under machine-transplanting conditions.The results showed that,the proper seeding rate of two types varieties is 2 seeds per potto 3 seeds per pot,the suitable seedling age and plant spacing of largepanicle variety is respectively:20 daysto 25days,and 15.7cm to 20.7cm;and the suitable seedling age and plant spacing of spike-grain balance variety is respectively:25 daysto 30 days,and 12.4~15.7cm.
