| 摘 要： | 目的]探索吡虫啉农药在枸杞生产中的适宜使用方法,为合理使用吡虫啉农药提供科学依据。方法]在田间条件下研究了10%WP吡虫啉不同浓度对枸杞果实主要次生物质类胡萝卜素、黄酮和多糖、总糖含量的影响及喷药时间。结果]不同浓度吡虫啉对枸杞果实次生物质和枸杞多糖含量有显著影响,药后1、7、14d的黄酮、多糖、总糖含量有依次增加的趋势,类胡萝卜素有降低的趋势。随着稀释倍数的增加,黄酮、多糖、总糖含量有增加的趋势,而类胡萝卜素含量有降低的趋势,但都以1800倍液最高。结论]吡虫啉10%WP的喷药剂量应以1800倍液的剂量较为宜。

| Abstract: | Objective] The aim was to seek the appropriate utilization methods for imidacloprid pesticide in the production of Chinese wolfberry,as well as to provide scientific basis for the rational use of imidacloprid pesticide. Method] The effect of different concentrations and spraying times of 10% WP of imidacloprid on the main secondary metabolites such as carotenoid and flavone,as well as the polysaccharide and total sugar content was studied in field. Result] The effect of different concentrations of imidacloprid on the secondary metabolites and the content of polysaccharide of Chinese wolfberry was significant. After imidacloprid spraying,the contents of flavone,polysaccharide and total sugar on the 1st,7th and 14th d showed increasing trend,while the content of carotenoid showed decreasing trend. With the dilution times increasing,the content of the flavone,polysaccharide and total sugar showed increasing trend,while the content of carotenoid decreased,in which the highest content of the secondary metabolites and polysaccharide appeared in 1 800 times. Conclusion] The dilution ratio of 1 800 times should be selected as the appropriate dosage of 10% WP of imidacloprid. |
