摘　　要：针对烟草种植过程中所施用化肥和农药的特点,结合近红外光谱预处理及定性分析中合格性测试方法,分别建立了四川泸州烟叶产区提苗复合肥(颗粒状)、吗胍·乙酸铜(粉剂)和甲基硫菌灵(悬浮剂)的合格性测试模型,结果表明该模型可有效鉴别其他不同生产厂家的化肥和农药产品,判别率均达到100%。该方法方便、快捷,适合烟草种植过程中施用化肥和农药的快速鉴别。According to the characteristics of chemical fertilizers and pesticides applied in tobacco planting,using the methods of NIR spectra preprocessing and qualification testing in qualitative analysis,this article constructed the models for the qualification testing of seedling-promoting compound fertilizer(granular),moroxydine·cupric acetate(powder)and thiophanate-methyl(suspending agent)applied in tobacco planting in Luzhou city,Sichuan province.The results showed that these models could effectively identify the chemical fertilizer and pesticide products produced by different manufacturers,and the discriminant rate reached 100%.This method was convenient and fast,and suitable for the rapid identification of chemical fertilizers and pesticides applied in tobacco planting.
