摘　　要：试验结果表明 ,地膜甜菜经化学调控可显著影响干物质积累与分配 ,有效控制地上部生长 ,促进地下部生长 ,提高根冠比 ,减少青头比率。以植物生长调节剂甜控一号效果最好 ,可使块根增产21.5 %,提高含糖率0.9%,投入产出比为1∶10.39 ;其次是缩节胺 ,可使块根增产17.0 %,提高含糖率0.8 %,投入产出比为1∶2.82 ;其它化控处理(除壮丰安外)The testing results have shown that the dry matter accumulation and distribution have influenced with sugarbeet chemical modified and controlling in the film mulching, the tops growth controlled, and root growth and promotion, the ratio of root/top increased, beet green headed decreased, result of plant regulator TIAN KONG 1 is the best, root yield increased 21.5%, sugar content increased 0.9%, ratio input output is 1∶10.39 and 2nd one is DPC root yield increased 17.0%, sugar content 0.8%, ratio of input output is 1∶2.82 and the other also gave good result of increasing yield and sugar.
