本文记述了三环唑在水稻上的残留消解动态。经两年、两地(浙江杭州、广东海南岛)在早、晚稻上进行了不同施药量、施药次数及距收期与农药残留量关系的试验。结果表明:稻壳中的残留量>土壤>稻米。稻壳中的残留量随施药量的增加而增加,而土壤中的残留量则不明显。每次用相同剂量,施药2次比1次的残留量略高。距收获前最后一次施药的时间缩短,稻壳和土壤中的残留量相应增加。在水稻灌浆期施药,稻壳中的残留量最高。提出了三环唑在水稻上的安全使用标准。
This paper describes the residual tricyclazole digestion dynamics in rice. After two years, the two places (Hangzhou, Zhejiang, Hainan Island, Hainan Island) in the early and late rice were carried out on different doses, the number of pesticides and the harvest and pesticide residues from the test. The results showed that the residual content of rice husk> soil> rice. The amount of rice husk residue increased with the amount of pesticide applied, but the soil residue was not obvious. Each time with the same dose, the application of pesticide residues twice a time slightly higher. The time from the last application before harvest was shortened, with a corresponding increase in residues in the husk and soil. Rice paddy application, rice husk residues in the highest. Proposed tricyclazole in rice on the safe use of the standard.
