摘要
对杂交水稻京福1优673的高产栽培技术进行探讨,以期促进京福1优673推广应用,实现杂交水稻良种良法配套。京福1优673参加福建省三明市区试2a平均产量489.8kg/667m2,比对照汕优63增产7.97%,达极显著水平,2a均为第2名。其高产栽培技术要点:稀播种,培育壮秧;适时移栽,合理稀植;合理施肥,控氮增钾;合理灌溉,壮根防倒;防治病虫草害,重点防治稻瘟病。
Key high-yielding cultivation techniques for a hybrid rice combination Jingfu 1 You 673 were discussed, in order to accelerate its extension and application and to implement the perfect integration of hybrid rice in elite variety and good cultivation techniques. Jingfu 1You 673 had an average grain yield of 489.9kg/667m^2 in two-year regional trials of Sanming city in Fujian province, 7.97% higher than that of control Shanyou 63 at significant level of 0.01, which both ranked the Second in two years. Its key high-yielding cultivation techniques were: sparse sowing, cultivating robust seedling, suitable transplanting time, rational planting density, fertilizer and water management, controlling nitrogen amount and increasing potassium fertilizer, improving root ability and avoiding lodging, and preventing disease, pest and weeds, especially in rice blast control.
