| 摘 要： | 为明确水稻调节肥施用技术,保障充足的穗数和粒数,试验通过随机区组设计,以空育131为试验品种,开展寒地水稻调节肥施用技术的研究,试验结果表明:调节肥的施用改变群体指标的数量关系,不能明显增强群体的素质,8叶追施氮肥通过增加颖花数和提高成穗率,增加水稻产量。

| Abstract: | Using random block design to research the application of rice regulating fertilizer which use Kongyu-131 as experimental material. The result indicated that rice regulating fertilizer can change quantity relationship of population indices,but population quality has been remarkably reinforced. additional nitrogen can use at eighth leaf stage to increase spikelet and productive tiller percentage so that increase rice yield. |
