摘　　要：用10%吡虫啉种衣剂处理黄瓜、西瓜、甜辣椒和大白菜几种主要蔬菜作物种子,研究了吡虫啉种衣剂对种子质量和贮存的影响。结果表明:吡虫啉种衣剂对试验蔬菜品种的田间出苗没有影响;包衣种子在常温下保存1 a后,其发芽率没有明显的降低。对不同药种比处理的西瓜种子在40℃恒温条件下进行了人工老化20 d,种子的发芽率与对照没有明显的差异;人工老化30 d时,所有处理种子的发芽率与对照比都有极显著的差异;药种比为1∶10的包衣种子发芽率从对照的100%下降到37%。使用吡虫淋种衣剂处理蔬菜种子时应选择合适的药种比,以达到防治虫害的效果,同时又不影响种子质量。Cucumber, watermelon, sweet peppers and Chinese cabbage seeds were coated with 10% imidacloprid seed coating fomulation. The influence of seed coating theatment on the seed quality and storage effects were studied. The results showed that it had not negatively influence on emergence of coated seed in the yield. Also it had no significant reduction on germination of coated seed stored for one year at room temperature. Watermelon coated seed at different product/seeds rate went through treatment of artificial ageing under the condition of 40℃. The results showed that seed germination had no significant differences compared with control when processing time was less than 20 days. But seed germination of all treatment had greatly reduction compared with control when processing time was 30 days. The germi nation rate of coated seed at 1 g production/10 seeds was 37% but 100% in control. This study showed that in order to control pests without affecting the seed quality, it was necessary to use imidacloprid seed coating fomulation with suitable product/seeds rate.
