【 摘 要 】

As the theoretical premise of the precision weed management, it is necessary to clear the effects of herbicide on the farmland weed seed banks. In this paper, the plots were carried out different managements in a piece of maize farmland including deep tillage/no-tillage, conventional fertilizer/no fertilizer, using herbicide/no weeding, the characters of the weed soil seed banks were tested; then, the effects of the herbicide on the characteristics of seed banks under different treatments were analysed. The results showed that, there were different levels of interactions between the managements on the characters of weed seed banks; herbicide significantly cut down on the seed density but had few effects on the species abundance of the weed soil seed bank; the highest seed reserve was found in the plot with no-tillage and no herbicide and the farmer conventional fertilizer management was helpful to reduce it.
