摘　　要：设置抛秧密度分别为15万、19万、23万、27万、31万穴/hm2 5个处理,考察抛秧密度对两系杂交中稻品种广两优1128产量的影响。结果表明,各抛秧密度处理间产量差异显著,以抛秧23万~27万穴/hm2时产量较高。In order to study the effect of different sendig-throwing densities on yield of rice variety Guangliangyou 1128,a comparison experiment of different density was carried out,and five density gradients of 150 000,190 000,230 000,270 000,310 000 seedling per hectare were set. The results showed that the yield of different density treatments were significant, and was relatively high in 230 000 to 270 000 seedling per hectare.

关 键 词：两系杂交中稻 广两优1128 抛秧密度 产量比较
