摘要
借助电子捕获检测器,田间试验研究了杀虫单在水稻-稻田系统中的动态残留,以了解杀虫单的降解与残留行为,合理且全面地评价其安全性并科学的指导其使用。结果表明,杀虫单在水稻植株、土壤和稻田水中的降解符合一级化学反应动力学方程。杀虫单在长沙和杭州两地水稻植株中的平均降解半衰期为11.06d,在土壤中的平均降解半衰期为9.48d,在稻田水中的平均降解半衰期为11.64d。
The residual behavior of monosultap on rice and the dynamic residue of monosuhap in rice-paddyfield system were studied ,by electron capture detector through field experiment. The results indicated that degradation of monosultap in rice plant, soil and paddyfield water followed the one-level dynamic equation. The average half life of monosaltap was 11.06 d of rice plant, 9.48 d of soil aad 11.64 d of paddyfield water in Changsha and Hangzhou.
