用超微粉型种衣剂包衣棉花种子，通过大田育苗试验，研究了超微粉棉花种衣剂对棉苗生长和苗期病虫害的影响，并与进口种衣剂进行了比较。结果表明，超微粉棉花种衣剂具有促控棉苗生长、提高棉苗综合素质与成苗率、有效防治病虫害等作用。与对照相比，包衣处理成苗率提高14.5%，根系活力提高16.4%；对苗期主要病虫害防效达82.0%-90.7%；其综合作用效果优于对比试验所用的二种进口种衣剂。

Effects of super micro-powder seed coating agent XM-1 on seedling growth, diseases and pests of cotton were studied by means of experiment of field raising seedling with coated cotton seed. Meanwhile its effects were compared with those of two export seed coating agents. The results show that this seed coating not only could regulate seedling growth, enhance seedling qualities and adult seedling rate, but also could prevent diseases and pests of cotton during seedling. The aduct seedling rate and root vigor of coating treatments increased 14.5% and 16.4% compared with uncoated comtrols, respectively. The prevention rate to main diseases and pests during seedling was 82.0%-90.7%. The general effects of this seed coating agent were better than those of two export agents used in this experiment.
