摘　　要：本文利用￣（１４）ＣＯ＿２示踪法研究了稀土元素对糖用甜菜块根膨大期和糖分积累期光合产物分配的影响，试验结果表明，喷施这当浓度稀土元素可提高甜菜同化ＣＯ＿２的能力，提高根冠比，改善光合产物的分配，有利于光合产物向块根运输，其中以０．０５％浓度处理的效果为最好。The effect of rare earth elements on the distribution of photosynthate in suger beet wasstudied.The results indicated that rare earth elements stimulated CO2assimilation,increasedthe ratio of root and tops (R/T),improved the distribution of photosynthate and stimulatedthe transport or organic matter from leaf to root of suger beet plant.The treatment with0.05%was shown to have the most significant effect among all the treatments。
