为揭示氯氰菊酯在荔枝中的消解动力学进行了荔枝田间试验。运用气相色谱仪测定了氯氰菊酯在荔枝土壤和荔枝中的残留量。两年的试验结果表明,氯氰菊酯在土壤和荔枝中消解迅速,在土壤和荔枝中的半衰期分别为8.6~9.60.0044~0.0165mg.kg-1(荔枝肉),均小于0.5mg.kg-1。
In order to reveal the digestion kinetics of cypermethrin in litchi, a field experiment was conducted in litchi. The residual content of cypermethrin in litchi soil and litchi was determined by gas chromatography. The results of two years showed that cypermethrin rapidly digested in soil and litchi, and the half-lives in soil and litchi were 8.6 ~ 9.60.0044 ~ 0.0165mg.kg-1 (litchi), less than 0.5mg.kg-1 .
