| 摘 要： | 在云南温暖粳稻区的牟定县和温凉粳稻区的大理市,通过对优质抗病滇型杂交粳稻滇杂32不同栽插密度进行试验,试验结果分析表明:滇杂32在温暖粳稻区的栽插密度以30.0万丛(穴)/hm2、2苗/丛产量最高,不同栽插密度之间产量差异达极显著水平;在温凉粳稻区的栽插密度以45.0万丛/hm2、2苗/丛产量最高,不同栽插密度之间产量差异达极显著水平。 |

| Abstract: | The planting density experiment of the elite Dian-type(Japonic) hybridize rice Dianza32 were conducted in two different area. One is in Mouding County where it is in warm Japonica rice area of Yunnan, the other is in Dali City where it is in cool-warm Japonica rice area of Yunnan. The results show that in warm Japonica rice area, Dianza32`s optimum planting density is 300 000 hills/hm2 and 2 seedlings/hill; in cool-warm Japonic rice area, it`s optimum planting density is 450 000 hills/ hm2 and 2 seedlings/hill. The different between the yields of different planting density is significant at 1% level in both experiments. |
