摘　　要：为有效控制植烟区烟田杂草，于2011—2014年利用诱萌法对四川省主要植烟区土壤杂草种子库的组成及数量进行了研究。结果表明，土壤杂草种子库样品中共有15科24种杂草种子，主要分布于0～15cm土层中。禾本科杂草为优势种群，其次为菊科杂草，再次为藜科杂草。双子叶杂草种类多于单子叶杂草，但其杂草种子数量明显少于单子叶杂草。广元烟区杂草种子库数量最大，达到19119粒／m^2；攀枝花烟区杂草种子库数量最小，为6177粒／m^2。For effectively controlling weeds in tobacco fields, the seed pools of weeds in main tobacco growing areas in Sichuan was studied in terms of composition and population with germination method in 2011-2014. The results showed that there included 24 weed species, belonged to 15 families, spread mainly in 0-15 cm soil layer. The dominant species were of Gramineae, followed by those of Compositae and then of Chenopodiaceae. The species of dicotyledonous weeds exceeded the species of monocotyledonous weeds in number, but the density of seed was obviously lower. The highest density （19 119 seeds/m^2） seed pool was found in the sample from Guangyuan, while the lowest （6 177 seeds/m^2） was found in the sample from Panzhihua.
