满益佳种衣剂在玉米上的应用效果研究

Study on Application Effect of Manyijia Seed Coating Agent on Maize

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。

In order to correctly evaluate the effect of Manyijia seed coating agent on maize growth and yield,compared with the treatment of conventional agent coating,this paper analyzed the effect of the treatment of Maniyijia seed coating agent on seedling emergence,growth,and yield of maize by using the method of field plot experiment.The results showed that,compared with the conventional agent coating treatment of 2.5%metalaxyl-M seed coating agent+20%fludioxonil seed coating agent,the coating agent of Manyijia increased maize seedling emergence rate by 3.0 percentage points,increased strong seedling rate by 3.5 percentage points.Meanwhile,it also promoted the growth of maize,increased plant height in five-leaf period by 7.42%,and increased root weight by 18.71%.Finally,the drying weight of ear and grain were increased by 4.95%and 6.53%,respectively,which led to a yield increase of 7.09%(14%standard moisture content).Therefore,the seed coating agent of Manyijia is suitable for large-scale popularization and application in Longxi County under the condition of the recommended dosage.
