田间试验表明，施用ＡＢＴ５号增产灵明显提高甜菜肥大直根的产量，且浸种处理的增产效果明显高于叶喷，而对含糖率无影响；形态指标测定表明，ＡＢＴ５号增产灵促进甜菜生长发育，加快了出叶速度，每株总叶片数增多，主根脱皮提前，体积增大；解剖观察表明，ＡＢＴ５号增产灵不影响甜菜根的初生生长和次生生长，只使三生生长提前，三生维管束轮数增加．甜菜苗期叶片数目与根结构的形成存在密切的相关性，且不受ＡＢＴ５号增产灵的影响。因此，甜菜苗期叶片数目仍可作为判断根结构的依据。
Field experiments showed that ABT5 was significantly increased yield of straight roots of sugar beet, and the effect of soaking seed treatment was obviously higher than that of leaf spray, but had no effect on the sugar content. The morphological index indicated that ABT No.5 enhanced the growth of sugar beet Development and speed up the leaf out speed, the total number of leaves per plant increased, the main root peel ahead of time, the volume increases; anatomical observation showed that ABT No.5 yield Ling did not affect the primary and secondary growth of beetroot, San students increased the number of vascular bundles. There was a close correlation between the number of beet seedling leaves and the formation of root structure, and was not affected by ABT5 ZSP. Therefore, the number of sugar beet seedling leaves can still be used as a basis for judging the root structure.
