| 摘 要： | 采用2因素3水平完全随机区组设计，在广西北流市民乐镇罗政村百亩连片“种三产四”丰产工程示范区进行特优233施N量与插植密度试验，探讨施N量与插植密度对该品种产量构成的影响。结果表明，随着施N量的增加，特优233的生育期、分蘖数、有效穗数、穗长、每穗总粒数、千粒重、理论产量和实际产量均呈增加趋势；随着插植密度的增加，单位面积基本苗数、有效穗数、理论产量均增加，而每穗总粒数则减少。方差分析结果显示，特优233以施N量300kg／ha、插植密度21万蔸／ha产量最高，增产最显著。说明该品种具有分蘖力强、耐肥抗倒的特点，其高产栽培方式宜采用高肥稀植。

| Abstract: | The present study was conducted to study the effects of nitrogen application and planting density on the yield components of rice variety Teyou 233 in Luozheng Village of Minle Township,Beiliu City,Guangxi.A completely randomized block design with two factors and three levels was used in the experiment.The results showed that the development and growth stages,number of tillers,effective panicles,length of panicle,total grains per panicle,weight of 1000-grain,theoretical and actual yields increased with incr... |
