| 摘 要： | 采用两裂式裂区试验探讨了丰两优1号的栽培技术,结果表明施氮方式和栽插密度都对产量有显著的影响,施氮水平与每穗实粒数、栽插密度与有效穗都存在极显著的正相关。在产量构成中有效穗影响最大,其次为穗实粒数。在大田生产中,要适当提高栽插密度,适宜播量为22.5万~28.13万穴/hm2;重施基肥,后期要增施粒肥均有利于提高产量。

| Abstract: | A experiment in the effect of application mode of nitrogenous fertilizer and planting density on medium indica hybrid rice combination-Fengliangyou No.1 was conducted in Hefei with the split-spot design and the results were as follow: both application mode of nitrogenous fertilizer and planting density affected rice yield significantly,There was a remarkably positive correlation between the amount of nitrogenous fertilizer and number of grain per spike,so did the planting density and productive panicle.The productive panicle was the most important component in yield structure and the number of grain per spike was the second.To give higher yield,the planting density should be increased reasonably and the basal fertilizer should be used heavily.In the late growing period,the nitrogenous fertilizer should be used to increase yield. |
