摘　　要：娃娃菜是西北黄土高原夏菜的主栽品种之一,本文采用大田定量喷洒农药和定时抽样检测试验,研究了不同农药在娃娃菜中的使用安全间隔期。结果表明,在推荐使用剂量条件下,不同农药在娃娃菜上的使用安全间隔期不同,其中辛硫磷的安全间隔期为7~14d,敌敌畏为5~7d,三唑酮和高效氯氟氰菊酯均为1~3d,高效氯氰菊酯为1h^1d;当农药施用量提高到推荐剂量的2倍时,不同农药的安全间隔期均提高1~14倍。The mini Chinese cabbage is one of the main varieties of summer vegetables in the plateau of the Loess plateau in Northwest China.In this paper,the method of quantitative spraying pesticides and timed sampling test was used to study the safety interval in the plateau summer vegetables.The results showed that under the recommended dosage conditions,the safety intervals of different pesticides were different.The safe interval of phoxim on the mini Chinese cabbage was 7-14 days,the dichlorvos was 5-7 days,the triazolone and the cyhalothrin were 1-3 days,and the beta-cypermethrin was 1 h-1 d.When the pesticide application rate was increased to twice the recommended application rate,the safety interval of different pesticides increased by 1-14 times.
