| 摘 要： | 采用田间试验方法,研究了三唑酮在荔枝园施用后的残留与降解情况.采用气相色谱法-氮磷检测器测定了三唑酮在荔枝果实和果园土壤中的残留量,结果表明:降解符合一级动力学方程,在荔枝和土壤中的半衰期分别为3.6～6.6d、4.1～4.8 d,但在正常使用条件下不会造成荔枝的残毒污染和土壤的残留积累.

| Abstract: | A field experiment was conducted to reveal dynamics of triadimefon in litchi and soil.Analytical method of triadimefon in litchi and soil by capillary column gas chromatography with Nitrogen-phosphorus detector has been established.The results of experiment showed that It breakdown follows first-kinetic order,and its half-life 3.6~6.6 days in litchi and 4.1~4.8 days in soil respectively.The pesticide residues in litchi were <0.01mg/kg. |
