| 摘 要： | 田间试验结果表明:种茎不同种植法对华南205木薯的产量及经济性状没有显著的影响,但平放种植法略优于斜插种植法;种茎芽眼方向对木薯的产量有显著的影响,鲜薯、薯干和淀粉产量均表现为芽眼向南>向东>向西>向北;当采用平放种植法时,木薯产量表现为种茎芽眼向南>向西>向北>向东;当采用斜插种植法时,产量表现为种茎芽眼向东>向南>向西>向北。因此,建议采用起垄、平放、种茎芽眼向南的木薯机械化种植技术。

| Abstract: | The results of field tests indicated that the different methods of planting cassava seed stem had no significant influ- ences on the yield and economic characters of cassava variety SC 205, but horizontally - positioned planting method was slightly bet- ter than oblique - positioned planting method. The bud - eye direction of seed stem had significant effect on the yield of cassava, and the yield of fresh tuber, dry tuber, and starch in various bud - eye direction treatments all revealed the following order： south- ward 〉 eastward 〉 westward 〉 northward. When horizontally - positioned planting method was used, the cassava yield showed the following sequence in bud - eye direction： southward 〉 westward 〉 northward 〉 eastward. When oblique - positioned planting method was adopted, the cassava yield could be arranged as follows ： eastward 〉 southward 〉 westward 〉 northward. Therefore, the mechanized planting technique （ including ridging, horizontally planting the seed stem, and making the bud - eye of seed stem southward） for cassava was suggested. |
