满益佳种衣剂在玉米上的应用效果研究

为正确评价满益佳种衣剂包衣对玉米生长及产量的影响，采用田间小区试验的方法，与常规药剂包衣处理进行对比，分析了满益佳种衣剂对玉米出苗情况、生长情况及产量的影响。结果表明，与常规药剂2.5%精甲霜灵种衣剂+20%咯菌腈种衣剂处理相比，满益佳种衣剂处理玉米出苗率提高3.0个百分点、成苗率提高3.5个百分点，同时也促进了玉米植株的生长，五叶期株高增加7.42%、根重增加18.71%，最终表现在穗风干重提高4.95%，籽粒风干重提高6.53%，产量（14%标准水分含量）增加7.09%。因此，满益佳种衣剂在推荐剂量条件下适合在陇西县大面积推广应用。

Effect of seed coating agent of Manyijia on strengthening seedlings and increasing yield of maize

The effect of seed coating agent of Manyijia on maize growth and yield was correctly evaluated by the method of field plot experiment compared with the conventional agent. The results showed that the coating agent of Manyijia increased maize seedling emergence rate by 5.8%, the rate of being strong plant by 3.3%. Meanwhile, it also promoted the growth of maize, e.g. increasing plant height by 7.42% and root weight by 18.71%. Finally, the drying weight of ear and grain were increased by 4.95% and 6.50%, respectively, which leaded to an increase yield (14% standard water) of 7.08%. Therefore, the seed coating agent of Manyijia is suitable to be widely applied in this area under the condition of recommended dosage.
