摘要:
为识别稻田治虫灌溉后杀虫剂毒死蜱随排水的输出特征,开展了稻田及周边水体中毒死蜱浓度的高频监测研究。研究结果表明,治虫灌溉期间稻田排水和农药输出都呈现很强的脉冲性,其中大于5 L/s高流量的排水脉冲过程发生次数1年不超过10次,且均为地表径流造成。建议控制地表径流的发生,同时通过利用沟塘等田间滞留措施减少农药流失。
Abstract:
High frequency monitoring of chlorpyrifos concentration in paddy fields and surrounding water bodies was carried out to identify the output characteristics of chlorpyrifos insecticide along with drainage after pest control irrigation in paddy fields. The results showed that the drainage and pesticide output of the paddy field showed a strong pulse during pest control irrigation, and the drainage pulse process with a high flow of more than 5 L/s occurred no more than 10 times a year, all of which were caused by surface runoff. It's suggested that the occurrence of surface runoff should be controlled and the loss of pesticide should be reduced by means of field retention measures such as ditch and pond.
