| 中文摘要: |
| 在田间条件下研究了甘农种衣剂Ⅰ号、甘农种衣剂Ⅱ号、甘农种衣剂Ⅲ号、阿维菌素种衣剂AV1、阿维菌素种衣剂AV2和5.7%甲维盐等6个种衣剂对小麦孢囊线虫病的防治效果。播种前对麦种进行8个不同种衣剂包衣处理，比较小麦收获后土壤中孢囊数量的变化以及小麦增产情况。结果表明，不同种衣剂处理对土壤中孢囊线虫的繁殖均有一定抑制作用，其中甘农种衣剂Ⅲ号(1∶35)、甘农种衣剂Ⅰ号(1∶50)和甘农种衣剂Ⅱ号(1∶35)孢囊减退率分别为56%、53%和47%。不同种衣剂处理的小麦产量增加，甘农种衣剂Ⅲ号(1∶35)、甘农种衣剂Ⅰ号（1∶50）、甘农种衣剂Ⅱ号（1∶35）和甘农种衣剂Ⅰ号（1∶35）增产率分别为37.6%、19.4%、17.9%和17.7%。本项目中自主研发的甘农种衣剂Ⅲ号防治效果最显著，不仅对小麦孢囊线虫病具有较好的防效，而且具有安全、低毒、省工、经济的特点，可在农业生产实践中进行推广应用。 |

| Effects of six kinds of seed coatings, Gannong seed coatingⅠ, Gannong seed coatingⅡ, Gannong seed coating Ⅲ, abamectin seed coating AV1, abamectin seed coating AV2 and 5.7% emamectin benzoate, on controlling cereal cyst nematode (Heterodera avenae) of wheat, were evaluated in this study. Wheat seeds were treated with eight different seed coatings before sowing and the changes in number of cysts in soil and wheat yield were compared after harvesting. The results showed that the numbers of cysts in soil with different treatments were clearly dropped after seed coating. When treated by Gannong seed coating Ⅲ(1∶35), Gannong seed coatingⅠ(1∶50) and Gannong seed coatingⅡ(1∶35), the cyst reducing rates were 56%, 53% and 47% respectively. Compared with control, the wheat yields increased 37.6%, 19.4%, 17.9% and 17.7% treated by Gannon seed coating Ⅲ(1∶35), Gannon seed coatingⅠ(1∶50)、Gannon seed coatingⅡ(1∶35) and Gannon seed coatingⅠ(1∶35) respectively. Gannon seed coating Ⅲ demonstrated the best control efficacy, with the characteristics of environmental safety, lower toxicity, labor and cost saving, which is suitable for wide application in practical disease control. |
