摘　　要：以苏玉糯2号为试验材料,研究密度对其鲜糯产量及效益的影响。结果表明,密度对苏玉糯2号的秃尖影响最显著,秃尖随密度的增加而增大,呈极显著正相关,相关系数R=0.946**,对穗长和穗粗的影响不大。以籽粒收获为目的,苏玉糯2号的最佳种植密度为6.75万株/hm2,而以收获鲜穗为目的,最佳种植密度则为6万株/hm2。The paper explored the effects of density on the fresh ear yielding and benefits of Suyunuo2. Density has a significant impact on the bald of Suyunuo2. The bald increases with the density, showing significant positive correlation, with correlation coefficient R= 0. 946 ＊＊, which has little impact on ear length and ear diameter. With the purpose of grain harvest of Suyunuo 2, the best planting density is 67 500 zhu/hm2, and with the purpose of harvesting fresh ear of Suyunuo 2, the optimum planting density is 60 000 zhu/hm2.
