摘要
苏玉10号种植密度试验结果表明:苏玉10号品种籽粒产量可达到12.400 t/hm2。高产群体质量的主要指标是:控制吐丝期LAI 5.04、群体干物质积累量9.000 t/hm2基础上,重点增加总粒数,提高粒叶比,提高花后干物质积累量和经济系数。籽粒产量(Y)与密度(x)的关系为Y=-301.48x2+4 158.5x-2778.7(R2=9119**),最佳密度为8.40万株/hm2。
The study of plant density of Suyu10 shows that the grain yield of Suyu10 can reach 12.400 t/hm2.The main quality indexes of high yield population include focusing on increasing total grains,raising the seed-leaf ratio,and enhancing dry matter accumulation and economic coefficient after flowering on the basis of maintaining LAI 5.04 in silk period and dry matter accumulation of the populations 9.000 t/hm2.The relationship between grain yield（Y） and density（X） is： Y=-301.48x2＋4158.5x-2778.7（R2=9119＊＊）,and the best plant density is 8.40×104 plants/hm2.
