甜菜丸衣种配方筛选及田间试验

The Formulation and Field Experiment of Sugar Beet Pelleted Seeds

经多年试验筛选，甜菜丸衣种配方已基本成熟，筛选出了甜菜丸衣种非活性组份中使用的填充剂和粘合剂以及活性组份的成份及使用量，确定出了配方中各成份的最佳比例为种子：D：A：B：粘合剂（a）=50：15：10：10：10：4。试验结果表明：与对照甜菜磨光种相比，定型产品（T3）能够提高田间出苗率，对苗期甜菜立枯病的防效为70．1％，对甜菜象甲的杀虫率为85．3％，块根产量增加14．9％，含糖率提高0．2°S，产糖量增长16．2％，经济效益显著。

The formulation of pelleted seeds in sugarbeet has been matured through many years research. Blinders,adhesives of non-active materials,the composition and quantities of active materials were selected for pelleted sugarbeet seeds. The optimum proportion of different composition in formulation was determined:Seeds: J: D: A: B: Adhesives(Q) =50: 15: 10: 10: 10: 4,Compared with polished seeds. The products (T3) can improve emergence rate in field. The effect of controlling leaf blight of sugarbeet was 70.1%,and the rate of killing snout beetle was 85. 3%, and root yield increased 14. 9%, Sugar content increased 0. 2%,Sugar yield increased 16. 2%,The benefit of economic is remarkable.
