通过田间多种药剂、不同剂量、不同用药时间、不同药次数试验,收集各处理小区的稻谷、稻草、土样,在室内对稻谷糙米中的农药残留量、降解动态进行检测分析,明确了大米中的农药残留量,直接与施药时间,农药品种、施药频数密切相关,残留量三唑磷>乙酰甲胺磷>甲胺磷>毒死蜱>吡虫啉>敌敌畏,从而为无公害优质米产业化、标准化生产中科学合理、安全用药提供了科学依据。 Through the field of a variety of drugs, different doses, different drug use time, the number of different drug trials, the collection of the various plots of rice, straw, soil samples, rice brown rice in the indoor analysis of pesticide residues, degradation dynamics, clear rice In the pesticide residues, directly with the application time, pesticide varieties, frequency of application is closely related to the residual triazophos acephate methamidophos chlorpyrifos imidacloprid, so as pollution-free high-quality rice industry , Standardized production of scientific and rational, safe drug provides a scientific basis.
