研究了不同栽培密度对‘晶糯8号’农艺性状与产量的影响。结果表明：1)密度在3.75×104~7.5×104株/hm2范围内，随着密度的增加，果穗长度缩短、粗度变细、穗行数和行粒数减少、秃尖长增加、单穗重逐渐下降，但产量不断增加。2)不同密度对株高和穗位高度的影响不明显。3)综合考虑果穗各个性状，‘晶糯8号’适宜的栽培密度为6.0×104~6.75×104株/hm2。

The effects of different cultivating densities on the yield and agronomic characteristics of ‘Jingnuo No.8 ’ are studied.The results show that 1 ) under different densities from 3.75×104 to 7.2×104plants/hm2,with the density increasing,the ear length has become shorter,ear diameter has become more tapering and ear row number and kernels per row have decreased,while the length of bald tip has increased;the single ear weight has decreased,but the yield has increased.2 )Different densities have insignificant effect on the plant and ear heights.3 )According to ear characteristics,the best cultivating density for Jingnuo No.8 is about 6.0×104~6.75×104 plants/hm2 in Nanjing.
