我国科学家近期研究发现,黄瓜幼苗根部和叶部对毒死蜱最敏感,毒死蜱使用5天内不宜种植黄瓜。研究人员在人工气候培养箱条件下,测定了毒死蜱不同浓度对黄瓜幼苗各部位生长的影响。结果表明:在毒死蜱0.5~80毫克/千克浓度范围内,黄瓜幼苗的株高、全株鲜重、 Recent studies in our country scientists found that cucumber seedling roots and leaves the most sensitive to chlorpyrifos, chlorpyrifos use within 5 days should not be planted cucumber. Researchers in the artificial climate incubator conditions, the determination of different concentrations of chlorpyrifos in various parts of cucumber seedlings growth. The results showed that in the concentration range of 0.5 ~ 80 mg / kg of chlorpyrifos, the plant height, whole plant fresh weight,
