摘　　要：为了探索出新两优6号在霍邱县农业生产中获得高产的最佳栽插密度,于2011、2012年在霍邱县进行了田间不同密度的栽培试验。结果表明:(1)在21万穴/hm2处理中,新两优6号平均产量为10 885.5kg/hm2,产量随密度12～21万穴/hm2逐渐增加,但在21～24万穴/hm2又突然下降,各处理间差异达到显著水平;(2)各密度间生育期和生育进程无差异,生育期均为130d;(3)优质杂交水稻新两优6号在霍邱县获得高产的最佳栽插密度是21万穴/hm2。In order to find out the variety gain the best yield from the suitable transplant rice seedlings density in our county agricultural production, the author made a test on the different transplant rice seedlings density of rice in the past two years.The results showed that：（1）the variety average yield was 10 885.5kg/hm~ in the 210 000 hole/bin2 processing,production gradually increased with the density from 120 000 hole/hm^2 to 210 000 hole/bin2, which drop from 210 000 hole/hm^2 to 240 000 hole/hm^2.The difference between the treatments achieved signifi- cant level;（2）the growth period and the growing process were indifference between the treatments, the growth pe- riod was an average of 130d; （3）the suitable transplant rice seedlings density of the new hybrid rice Liangyou No.6 gaining the best yield was 210 000 hole/hm^2 in our county.
