4%立枯灵在烤烟育苗上的应用研究

本文为１９９８年在延边大学农学院烟草试验区和和龙等地进行的４％立枯灵粉剂在烤烟育苗上的应用试验结果，一次性用９８％溴甲烷熏蒸处理的营养土做成的床面，每平方米拌０．８１ｇ立枯灵粉剂，在小十字期、假植前一周、假植还苗后各喷一次立枯灵，每一次喷雾量为每平方米０．８１ｇ立枯灵加水２ｋｇ（处理Ｂ），对提高烤烟幼苗的农艺性状效果，明显比其它处理好，又经方差分析差异显著．尽管处理（处理Ｂ）对苗期猝倒病和立枯病等病害的防治效果比敌克松好，但不如甲基托布津，而立枯灵比甲基托布津具有明显的促进幼苗生长和培育壮苗的作用，深受用户欢迎，可以推广施用．

The Application and Studies on Cured Tobacco's Grow Seedlings of Using 4%Taghigaren

This paper was the experiment results of the application on cured tobacco's grow seedling of using 4%taghigaren on Agric. Coll. of Yanbian University and Helong test field. Tobacco seedlings were spurted with taghigaren(0.81g tag. 40000g H2O/m2)three time at little cross, before one week of false planting, after false planting which bed(0.81g tag./m2)was made of nutritive soil treated by 98%zytox, their agronomy characters were better than other treatment, and the variance analysis show significance of difference. Though treatment B's prevenction and cure was better than dexon for cataplexy and damping-off, but was worse than the others, and taghigaren has better significent facilitation for seedlings to grow and plant strongly. It is welcome to popularize.
