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。
Su Yu 10 planting density test results show that: Suyu 10 varieties of grain yield can reach 12.400 t / hm2. The main indicators of high-yielding population quality are: control of LAI 5.04 in silking stage, population dry matter accumulation of 9.000 t / hm2, on the basis of increasing total grain number, increasing grain-leaf ratio and increasing post-anthesis dry matter accumulation and economic coefficient. The relationship between grain yield (Y) and density (x) was Y = -301.48x2 + 4 158.5x-2778.7 (R2 = 9119 **) with the optimum density of 84000 plants / hm2.
