Regulating Yield and Lodging-resistance of Ratoon Rice,Jiafuzhan

  • 摘要: 为探索佳辐占作再生稻机械化栽培高产抗倒的调控技术,在头季设置施氮量和抗倒剂试验发现:增施氮肥,促进茎蘗数和叶面积发展,干物质积累增加,以每667m2施氮量13.8kg的产量最高,施氮量9.2kg次之,但二者产量差异不显著;茎秆弯曲力矩随施氮量提高而增加,茎秆抗折力与施氮量呈抛物线型相关,每667m2施氮量13.8kg处理的茎秆弯曲力矩显著较大,而茎秆抗折力显著较低,于成熟期出现倒伏;加施抗倒剂立丰灵有显著降低弯曲力矩和增加茎秆抗折力的效果。结果表明,适量施用氮肥,配施抗倒剂是保障再生稻佳辐占机械化栽培高产抗倒的关键措施。
    Abstract: In preparation of using the high-yield ratoon rice,Jiafuzhan,for mechanized cultivation,the stalk-lodging control with nitrogen(N)fertilization and the application of a lodging agent were testedon the initial crop of the rice.The results showed that N fertilization increased the tiller count,leaf area and dry matter accumulation.At13.8kg N per 667m2,the highest yield was obtained.It followed by the N fertilization of 9.2kg.However,the yields were not significantly different.The bending moment of the rice stalks increased with increasing N application.The resistance of lodging(EPT)related to N addition in a parabolic function.The 13.8kg N per667m2 treatment significantly increased the bending moment of stalks,but less apparent on EPT with lodging observedat maturity of the plant.The Gasch lodging agent,Lifengling,significantly reduced the bending moment and increased the effect on EPT of the rice stalks.It appeared that,through adequate applications of both N fertilizer and lodging agent,Jiafuzhan could be adequately applied inmechanized cultivation.
