摘　　要：农田杂草土壤种子库是农田生态系统的重要组成部分。在收集国内外相关研究资料的基础上,系统综述了施肥模式对农田杂草土壤种子库的密度、物种组成、多样性等动态特征的影响,结合国际研究动态,就目前我国农田杂草土壤种子库研究中亟需解决的问题进行了探讨,指出应加强在施肥条件下杂草种子的萌发、土壤种子库特征的变化机制、土壤种子库与地面杂草群落的相关性、土壤中杂草种子的遗传变异等4个方面的研究工作,深入探讨施肥模式对农田土壤种子库及农田生态环境的影响。Weed soil seedbank of farmland has been considered as an important part of farmland ecosystem.Here we had collected the relevant research reports under different fertilization patterns worldwide,and then attempted to summarize the progress on the soil seedbanks density,species composition and diversity.We also proposed some perspectives on what are the problems in soil seedbank research and how to resolve them in near future,pointing out what work can be carried out on the germination of weed seed,the mechanism of soil seedbank change,the relationship with ground weed community,and the genetic variability of weed seed under different fertilization patterns.
