| 摘 要： | 田间试验条件下,以吉花19花生品种为材料,设置6个赤霉素浓度和氯虫苯甲酰胺800倍液混配处理,以清水、30mg/L赤霉素和氯虫苯甲酰胺800倍液为对照进行拌种,研究其对花生出苗情况、防虫效果和产量的影响。相较于氯虫苯甲酰胺800倍液单剂处理,6种混配组合出苗率提高了0.34%~5.17%,增产0.08%~12.44%。部分混配组合明显增强了吉林省蛴螬、棉铃虫和斜纹夜蛾3种主要花生虫害的防治效果,最大提升幅度分别为6.66、9.68和7.89个百分点,均达到极显著水平。赤霉素浓度控制在20~40mg/L范围内,其与氯虫苯甲酰胺800倍液混配时花生出苗情况、防效及产量俱佳。

| Abstract: | Under field condition, with water, 30 mg/L gibberellin and 800 times solution of chlorantraniliprole as controls, Jihua19 was coated and used to study the effect of seedling emergence rate, controlled effect to pests and yield of 6 concentrations of gibberellin mixed with 800 times solution of chlorantraniliprole.Compared to 800 times solution of chlorantraniliprole, the emergence rates of all mix were increased by 0.34%~5.17 %, and the yields were increased by 0.08%~12.44%.In partial mixed treatment,the controlled effect to grubs, cotton bollworm and Spodoptera litura were enhanced significantly, the maximum increase rates were 6.66, 9.68 and 7.89 percentage points respectively, reached a very significant level.So when gibberellin concentration range was between 20 mg/L and 40 mg/L, the seedling emergence rate, the controlled effect to pests and yield of gibberellin mixed with 800 times solution of chlorantraniliprole were better than others. |
