以松粳6号和超级稻松粳9号两个寒地粳稻品种为试验材料,研究了不同插秧密度对寒地粳稻产量及产量构成因素的影响.结果表明,不同插秧密度对两品种千粒重影响相对较小,而对每穴穗数和每穗粒数的影响相对较大.在黑龙江省第一积温带地区,松粳6号和超级稻松粳9号的最适插秧行株距为30cm×13.3cm和30cm×16.7cm.
Effects of Different Transplanting Density on Yield and Yield Component of Japonica Rice in Cold Region
"Songjing 6"and super rice vatiety"Songjing 9"from the cold zone were used in this experiment to study effects of different transplanting density on the yield and yield component of Japonica rice.The results showed that the effects of different transplanting density on their 1000-grain weight was relatively less than those on spike number per hill and kernel number per spike.In the area of the first accumulated temperature zone of Heilongjiang Province,the optimum transplanting density for Songjing 6 was 30×13.3cm,and that for super rice Songjing 9 was 30×16.7cm.
