近五年水稻杀虫剂的使用现状
摘 要
我国是世界上最大的水稻种植国，水稻害虫一直为害严重。对于不同的水稻害虫结合不同地方的生态环境，我们需要选择不同的防治措施进行防治，以达到减少农业经济损失的目的。为了解我国近五年水稻杀虫剂的使用现状，科学合理使用水稻杀虫剂以及延缓害虫抗药性发展作参考，本论文对近五年（20152019年）水稻杀虫剂的使用现状进行了调查。本研究以数据库查询的方式，对我国水稻杀虫剂的种类、数量、防治对象等情况进行调查，对所获得的数据进行统计分析。共调查到水稻杀虫剂69种，其中品种最多的是有机磷类杀虫剂（20.29%）和吡啶类杀虫剂（14.19%）主要用于褐飞虱、二化螟和稻纵卷叶螟等害虫的防治。其中，用于防治稻飞虱的主打有效成分是噻虫嗪、吡蚜酮、异丙威，防治二化螟和三化螟的主打有效成分是杀虫双与氯虫苯甲酰胺，防治稻纵卷叶螟的主打有效成分为甲维盐、阿维菌素和毒死蜱。根据上述的调查结果，近五年我国对水稻杀虫剂的使用品种还是以有机磷类杀虫剂较多，其中毒死蜱占据 *51今日免费论文网|www.51jrft.com +Q: *351916072*

Investigation on the Use of Rice Pesticides in Recent Five Years
ABSTRACT
China is the largest ricegrowing country in the world, and the plague of rice pests has been serious. Because of various kinds of rice pests combined with the ecological environment in different places, different control measures should be taken to solve the reducing agricultural economic losses by the plague of rice pests. Research shows rice pesticides used scientifically and reasonably will have an important effect on delaying the development of pest resistance, and the survey had been conducted to collect and analyze the consume of rice pesticides in China in the past five years (20152019). The data of types, quantities, and control targets of rice pesticides was collected from CNKI and then the data obtained was further analyzed. Results show that total 69 rice insecticides had been mainly used to control the Nilaparvata lugens, Chilo suppressalis and Cnaphalocrocis medinalis and other pests. The largest proportion of rice insecticides in the result was organophosphorus insecticides (20.29%), followed by pyridines insecticides (14.19%). The main active ingredient for the control of rice planthoppers are thiamethoxam, pymetrozine, isoprocarb. The main active ingredients for the control of Chilo suppressalis and Scirpophaga incertul are bisultap, chlorantraniliprole. The main active ingredients for the control of Cnaphalocrocis medinalis are abamectin, emamectin benzoate, chlorpyrifos. According to the survey results, in recent five years, organophosphorus insecticides was mainly used in China and chlorpyrifos is an important position of organophosphorus insecticides.
