摘　　要：为促进水稻高产优质栽培,采取随机区组设计进行垦稻26和龙粳31高产优质群体优化研究。结果表明:垦稻26以5苗·穴^-1、行距30.0cm,株距12.6cm为最佳群体,产量高达11 481.0kg·hm^-2,较对照增产4.4%;龙粳31以5苗·穴^-1、行距28.5cm、株距13.3cm为最佳配置,产量达8 553.0kg·hm^-2,较对照增产3.6%。因此,合理配置穴苗数和行株距是实现水稻高产优质最为快捷、最为经济有效的措施。In order to promote high-yield and high-quality cultivation of rice,random block design was used to optimize the high-yield and high-quality population of Kendao 26 and Longjing 31.The results showed that the best rice population,Kendao 26,was planted in the configuration of 5 rice seedlings per hole,row spacing of30.0 cm,and plant spacing of 12.6 cm;its yield reached 11 481.0 kg·hm^-2 and the yield rate was increased by4.4%in comparison with that of the control group.The best configuration was the one applied on Longjing 31,in which the rice population was sown in a manner of 5 rice seedlings per hole,row spacing of 28.5 cm,and plant spacing of 13.3 cm;its yield reached 8 553.0 kg·hm^-2 and the yield rate was increased by 3.6%in comparison with that of the control group.Hence,the reasonable configuration of rice seedlings per hole,row spacing,and plant spacing is the fastest,the most economic,and the most effective measure to achieve high yield and high quality of rice.
