摘　　要：为探讨平地种植木薯不同种茎种植角度对木薯产量性状的影响,以华南8号木薯种茎为试材,比较种茎的0°平放（CK）、30°斜插、60°斜插、90°竖插和270°倒插5种处理对木薯产量的影响。结果表明,5种处理的薯干率和鲜薯淀粉含量之间存在较小差异,鲜薯产量、薯干产量和淀粉产量均表现60°斜插〉30°斜插≈竖插〉倒插≈平放,其中,60°斜插比30°斜插和竖插增产11.1%~13.4%的鲜薯、薯干和淀粉,60°斜插比倒插和平放增产18.0%~20.3%的鲜薯、薯干和淀粉。在平地种植木薯时,建议以60°斜插种茎为优,其次是30°斜插和竖插,不宜倒插。The purpose of the study was to investigate the cassava yield influence of different planting stake angles on flat field. The cassava variety of South China No.8 was used as the material, five planting stake angle treatments were 0°（horizontal）, 30°（inclined）, 60°（inclined）, 90°（vertical）, 270°（inverse）. The results showed that a little differences in dry matter content ratio and starch content of fresh roots between among different treatments. The yield of fresh root, dry root and starch were listed in the following order 60°〉30°=90°〉270°=0°. The yield of the 60° inclined was 11.1%-13.4% more than the 30° inclined and the vertical, and 18.0%-20.3% more than the inverse and horizontal. Therefore, the planting angle 60°inclined for cassava on flat field was recommend, follow by 30° inclined and vertical.
