Study on Pesticide Residues of Phorate and Emamectin Benzoate in Cauliflower with Ball Well Protected

完全覆盖花椰菜甲拌磷和甲维盐农药残留研究（英文）

In order to study the difference between cauliflower varieties with ball well protected and unprotected in terms of pesticide residue and its causes, Jinpin 70, a new male sterile cauliflower variety with ball well protected, and Xuebao with ball unprotected were sprayed with high-toxic pesticide phorate and efficient bio-pesticide emamectin benzoate at a regular dose to investigate the impact of different cauliflower varieties on the pesticide residue. The results showed that from the 3rd to the 5th day after spraying, phorate and emamectin benzoate residues in Jinpin 70 with ball well protected reduced by 76.47%-87.65% and 67.86%-80.82% re- spectively compared with Xubao, and decreased by 9.23%-81.82% and 57.14%- 79.84% respectively compared with Jinpin 70 with ball unprotected. The results above demonstrates that inner leaves of cauliflower with ball well protected can prevent the ball from being polluted by phorate and emamectin benzoate, thereby improving its edible safety.

为了研究完全覆盖花椰菜品种与不覆盖花椰菜品种农药残留量的差异以及造成差异的原因．以完全覆盖花球的花椰菜雄性不育新品种津品70为研究对象，以不覆盖花球花椰菜品种雪宝和去除内叶的津品70为对照．通过喷洒高毒农药甲拌磷和高效生物农药甲维盐．调查不同类型花椰菜花球上的农药残留量。结果表明：与对照品种雪宝相比．同一检测时期（喷药第3—5d）全覆盖津品70甲拌磷和甲维盐的残留量分别降低76．47％～87．65％和67．86％～80．82％：与去除内叶的津品70相比，全覆盖津品70甲拌磷和甲维盐的残留量分别降低69．23％～81．82％和57．14％～79．84％。说明完全覆盖花椰菜品种的内叶可以很好地阻隔药剂污染，提高菜品的食用安全性。
