摘要
在0.8~1.0 m行距和0.15~0.25 m株距条件下,采用9种不同株行距配置方式,在海南省种植短蔓型甘薯品种广薯79,结果表明:加宽行距有利于提高分枝数、单株鲜薯重、干物率、薯干产量和淀粉产量;缩小株距有利于提高鲜薯产量和薯干产量;加宽株距有利于提高分枝数、单株结薯数、单株鲜薯重和大中薯比率。在9个处理中,0.8 m×0.15 m株行距配置方式收获最高的鲜薯产量,(0.9~1.0 m)×(0.15~0.20 m)株行距配置方式获得较高的薯干产量和淀粉产量。
Under the experimental conditions of row spacing 0.8~1.0 m and plant spacing 0.15~0.25 m in Hainan province,the effects of nine different plant-row spacing treatments on the growth and yield characters of short-vine type sweet potato variety Guangshu 79 were studied.The results showed that widening row spacing was advantageous to improve the number of base branches,fresh root weight per plant,dry matter rate,yield of dry root slice and starch yield.Reducing plant spacing was propitious to improve the yield ...
