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。
The high-yielding cultivation techniques of hybrid rice Jingfu 1 You 673 were discussed in order to promote the promotion and application of Jingfu 1 You 673, and to realize the hybrid cultivation of good varieties of hybrid rice. Jingfu 1 You 673 participated in the trial 2a average yield of 489.8kg / 667m2 in Sanming City, Fujian Province, 7.97% higher than the control Shanyou 63, reached the extremely significant level, with 2a being No. 2. Its high-yielding cultivation techniques: dilute sowing, nurturing strong seedlings; timely transplanting, rational thinning; reasonable fertilization, nitrogen control by potassium; reasonable irrigation, strong roots fall prevention; pest control pests, focusing on the prevention and control of rice blast.
