摘要
[目的]探讨不同栽培模式下木薯的抗风能力,为木薯抗风栽培技术研究提供参考。[方法]开展种茎环剥、留单(双)茎杆、喷施多效唑、打顶等田间试验,测定木薯株高、茎粗、节间距、分枝数、薯块产量、淀粉等指标。[结果]在环剥双杆条件下,打顶显著降低株高;单杆打顶和2次喷施多效唑均能增加茎粗。环剥双杆+前期(株高0.7 m)打顶显著增加了淀粉含量和产量。[结论]环剥+双杆+前期(株高0.7 m)打顶+单杆打顶+2次喷施多效唑的栽培模式可提高木薯抗风能力。
[Objective]To study the wind-resistant performance of cassava under different cultivation methods,and to further provide references for cassava wind-resistant cultivation.[Method]A field trial was carried out with stalk girdling,single or both shoots remaining,spraying paclobutrazol,tip pruning and so on.We measured the plant height,stem diameter,node distance,branch number,root yield and starch content and so on.[Result]Plant height decreased significantly under the treatment of stalk girdling+both shoots remaining.Treatments of tip pruning and spraying paclobutrazol twice could enhance the stem diameter.Treatment of stalk girdling+both shoots remaining+tip pruning(0.7 m plant height)significantly enhanced the starch content and yield.[Conclusion]Wind-resistant performance of cassava could be enhanced under the cultivation mode of stalk girdling+both shoots remaining+tip pruning(0.7 m plant height)+single shoot remaining and tip pruning+spraying paclobutrazol twice.
