温室黄瓜;华南型;华北型;农药残留;百菌清;多菌灵;代森锰锌;吡虫啉
摘  要:
以华南型黄瓜和华北型黄瓜为研究对象,研究在不同施药条件下,施药后不同间隔期果实内百菌清、多菌灵、代森锰锌、吡虫啉的残留量。结果表明:黄瓜果实中农残量随施药与采收间隔期的延长呈下降趋势;华南型黄瓜的农残量显著低于华北型黄瓜;生产中农民使用喷雾方法防治黄瓜叶部病害,黄瓜果实中的农药残留量一般情况下不会超过国家最大限量标准。

摘  要:
The residues of chlorothalonil,carbendazim,mancozeb and imidacloprid in cucumber from South China and North China cultivars were analyzed at 2-day intervals 1 day after administration under various conditions.The results showed that pesticide residues decreased with prolonged time interval between administration and harvesting.Pesticide residues in South China cultivar was significantly lower than those in North China cultivar.When cucumber was protected against diseases by leaf spray,pesticide residues in cucumber fruits did not generally exceed the national maximum limits.
