摘　　要：为研究滇一型杂交粳稻对复合肥的利用效应,挖掘其产量潜力,以滇杂31、滇杂35、滇杂40为材料,分别施用4个水平的复合肥,对其产量及其构成要素进行比较。结果表明:3个杂交粳稻的有效穗数、穗粒数及单株产量均随复合肥用量的增加而增加,各处理间差异达显著或极显著水平;除滇杂35外,其余杂交粳稻组合的结实率在不同复合肥用量处理间无显著差异;千粒重受自身遗传特性的影响较大,环境对其影响较小,同一材料在不同肥料用量间差异不大。三个杂交粳稻均在处理Ⅳ(18kg/667m2的复合肥标准施肥)中具有最高的单株产量。In order to study the utilization effect of compound fertilizer on Dian-1 type japonica hybrid rice,and excavate the yield potential,in this paper,the yields per plant and yield components of three Dian-1 type japonica hybrid rice combinations of Dianza 31,Dianza 35 and Dianza 40 were analyzed by applying four different compound fertilizer amounts.The results showed that effective panicles,grains per panicle and yields per plant of all combinations increased with the rising of compound fertilizer amounts.Significant or extremely significant differences existed among different treatments.In seed setting rate,only Dianza 35 had significant difference among four treatments.1000-grain weight was not much influenced by compound fertilizer amount,it was mainly determined by its genetic features.The yields per plant of three Dian-1 type japonica hybrid combinations were the highest under treatments Ⅳ that the compound fertilizer amount is 18 kg/667m2.
