摘　　要：探讨了稀植栽培对3个木薯品种生长发育的影响。结果表明:木薯稀植栽培的种植密度比对照降低了13.34%~55.56%,产量增加了350.00~6927.84 kg/hm2,块茎淀粉含量提高了28.45%;与对照相比,木薯稀植栽培的植株高度和一级分枝高度分别增加了9.43%~93.93%和19.29%~101.68%,主茎直径和最大薯块直径分别极显著增大了7.02%~65.57%和21.17%~67.52%;稀植栽培处理因子对木薯的生长发育具有极显著的影响;稀植栽培减少肥料使用量9.54%~37.54%,管理和收获效率分别提高了15.00%~25.00%和15.00%~20.00%,减少劳动力投入20.00%~25.00%。The effects of sparse planting on the growth and development of three cassava varieties were studied in the paper.The results showed that compared with the control,the planting density of sparse planting cassava decreased by 13.34%~55.56%.The yield increased by 350.00~6927.84 kg/hm2,and the starch content of tuber increased by 28.45%.Plant height in⁃creased by 9.43%~93.93%.Primary branch height increased by 19.29%~101.68%.Main stem diameter and maximum root di⁃ameter were significantly increased by 7.02%~65.57%and 21.17%~67.52%.The treatment factors of sparse planting had a sig⁃nificant effect on the growth and development of cassava.Sparse planting reduced fertilizer by 9.54%~37.54%.The management and harvest efficiency increased by 15.00%~25.00%and 15.00%~20.00%,respectively,and labor input reduced by 20.00%-25.00%。
