种植种茎的芽眼朝向对华南8号木薯产量性状的影响

以华南8号木薯为材料,通过试验比较了在水平种植时,种茎芽眼的4个朝向(芽向)在木薯产量性状上的效应.结果表明,芽向对木薯产量性状有较大影响,鲜薯、薯干和淀粉的产量排序依次为向南>向西>向北>向东(CK),最高产的芽眼向南处理比最低产的芽眼向东处理(CK),提高鲜薯产量38.8%、薯干产量36.3%和淀粉产量34.8%;次高产的种茎芽眼向西处理比芽眼向东处理(CK)提高鲜薯产量24.9%、薯干产量24.5%和淀粉产量24.6%.我国在种植木薯时,建议采用种茎芽眼朝南、朝西或朝西南的水平摆种方式.
Different Bud Direction of Horizontal Planting Cutting on the Yield of Cassava
The cassava variety South China No.8 was used in the study, The results showed that the yield was significantly influenced by the bud direction while planting and the yield rank of fresh root, dry root, starch was in the order from high to low: South, Western, North, Eastern. The highest yield of South bud direction was improved by 38.8% for fresh root yield, 36.3% for dry root yield and 34.8% for starch yield than CK; the secondary highest yield of Western bud direction was improved by 24.9% for fresh root yield, 24.5% for dry root yield and 24.6% for starch yield than CK. So, the bud direction of South, Western or South-Western were recommended for horizontal planting cassava in China.
