摘　　要：以罂粟为供试材料,用不同浓度的2,4-D丁酯对罂粟进行茎叶喷施处理,研究2,4-D丁酯对罂粟叶绿素含量及光合作用的影响。结果表明,随着2,4-D丁酯处理后时间的延长和2,4-D丁酯浓度的增加,罂粟叶片中的叶绿素含量显著降低,光合速率(Pn)、气孔导度(Gs)、胞间CO2浓度(Ci)也均显著降低,说明2,4-D丁酯对罂粟具有很好的防除效果。Opium poppy is one of the most important drugs,and this study is designed to kill Opium poppy with phenoxy acid herbicides which have strong selectivity and broad spectrum herbicide,providing a theoretical basis for killing opium poppy by chemical control methods.The experiment using different concentrations of metolachlor for leaf spraying on opium poppy,the results showed that as time increases and the increased concentration of 2,4-D herbicide,the chlorophyll content,photosynthetic rate（Pn）,stomatal conductance（Gs）,intercellular CO2 concentration（Ci） were significantly reduced in leaves of Opium poppy.This indicated that 2,4-D butyl has good control effect on Opium poppy.
