【摘要】 利用正交试验,对影响杂交稻新组合Ⅱ优129产量的三个主要栽培管理因素:氮肥施用方法、种植密度、纯氮施用量进行初步分析,结果表明,每667m2中插植1.5万穴,基肥中氮肥占总施氮量70%,每667m2施用纯氮15kg可实现较高的产量水平。更多还原

【Abstract】 A high-yielding cultivation techniques for hybrid rice ⅡYou 129 was studied by the method of orthgonal experiment design. Three influential elements for the cultivation techniques were fertilizer mothods of nitrogen,transplanting density and amount of pure N. The results showed that 15000 hills per 667m2, 70 percent of total N used as basic fertilizer and 15kg pur N fertilized per 667m2 can reach higher yielding .更多还原
