种茎种植方式及芽向对木薯农艺和产量性状的影响
以华南205木薯为材料,开展两因素随机区组试验,植后2个月调查各小区的成活株数,收获时调查各小区的农艺和产量性状。结果表明：种植方式和芽向均对木薯农艺和产量性状产生明显影响,种植方式的影响大于芽向;平放比斜插增产鲜薯22.5%、薯干19.9%、淀粉17.6%,鲜薯和薯干达到显著差异水平;不同芽向的木薯产量均表现为芽眼向南〉向东〉向西〉向北,向南处理比向北增产鲜薯34.1%、薯干38.0%、淀粉42.0%,均达显著差异水平。其中,平放种植的木薯产量均表现为种茎芽眼向南〉向东〉向北〉向西,为逆时针趋势,向南处理比向西增产鲜薯40.82%、薯干42.68%、淀粉44.29%,差异均达显著水平;斜插种...

| Bibliography: | 36-1124/S The cassava variety SC 205 was used as experimental material to conduct two-factor randomized-block test.The survival rates of seedlings in each plot were investigated two months after planting,and the agronomic and yield characters of cassava plants in each plot were recorded in harvest period.The results showed that both seed-stem planting pattern and bud-eye direction had obvious effects on the agronomic and yield characters of cassava plants,and the effect of planting pattern was greater than that of bud-eye direction.As compared with the inclined planting,the horizontal planting increased the fresh tuber yield,dry tuber yield and starch yield of cassava by 22.5%（P〈0.05）,19.9%（P〈0.05） and 17.6%,respectively.The effects of different bud-eye directions on cassava yield exhibited the following order：southward eastward westward northward,the fresh tuber yield,dry tuber yield and starch yield of cassava in the southward bud-eye treatment were separately 34.1%,38.0% and 42.0%higher than those in the no |
