超微粉体玉米种衣剂是江苏里下河地区农业科学研究所研制的新型种衣剂,为明确超微粉体玉米种衣剂对玉米种子萌发出苗、幼苗生长的促进作用以及对玉米丝黑穗病的防治效果,利用超微粉体玉米种衣剂1号、2号进行包衣处理,以不包衣处理为空白对照(CK1),以市售玉米种衣剂为普通种衣剂对照(CK2)。结果表明,与不包衣空白对照相比,超微粉体玉米种衣剂1号、2号可显著改善玉米幼苗素质,与普通玉米种衣剂对照的效果相当;超微粉体玉米种衣剂2号处理的玉米丝黑穗病株率显著低于不包衣对照和普通玉米种衣剂对照;超微粉体玉米种衣剂1号、2号较不包衣空白对照增产10%以上。
Superfine powder corn seed coating agent is a new type of seed coating agent developed by Jiangsu Lixiahe Agricultural Science Institute. In order to clarify the effect of ultrafine powder corn seed coating agent on germination and seedling emergence and seedling growth of corn seeds, Smut prevention and control effect, the use of superfine corn seed coating agent No. 1, No. 2 for coating treatment without coating treatment as a blank control (CK1), the commercially available corn seed coating agent for the general seed coating Control (CK2). The results showed that compared with the blank control without coating, corn seed coating agent No.1 and No.2 could significantly improve the quality of corn seedling, which was equivalent to that of common corn seed coating agent. The rate of maize head smut of agent 2 was significantly lower than that of uncoated control and common corn seed coating agent. Superfine corn seed coating agent No.1 and No.2 were more than 10% more than the blank control .
