| 摘 要： | 以华南8号木薯为材料,比较5个施肥深度处理对木薯产量性状的效应。结果表明,在0～12 cm施肥深度中,按鲜薯、薯干和淀粉产量的排序为施肥深度6 cm>0 cm>9 cm>3 cm>12 cm6,cm施肥深度的鲜薯、薯干和淀粉产量分别比0cm(CK)增加7.5%、5.3%和3.9%,3 cm和9 cm施肥深度的鲜薯、薯干和淀粉产量略低于0 cm(CK),12 cm施肥深度的鲜薯、薯干和淀粉产量分别比0 cm(CK)减少15.1%、18.6%和21.1%。推荐木薯施肥深度为0～9 cm,以6 cm施肥深度为最优。

| Abstract: | Taking cassava variety Huanan No.8 as test material,the effects of 5 different fertilization depth treatments on the yield characters of cassava were compared.The results indicated that: among different treatments of 0~12 cm fertilization depth,the yield of fresh tuber,dry tuber and starch all had the following order: 6 cm depth> 0 cm depth > 9 cm depth > 3 cm depth > 12 cm depth.Comparing with the treatment of 0 cm fertilization depth(CK),the yield of fresh tuber,dry tuber and starch in the treatment of 6 ... |
