Results show that there are 66 weed species of 28 families, mainly Compositae and Gramineae,found in the seed production field. More of the weeds are perennials. The trend of change of species richness, indices of weed diversity, evenness, and dominant concentration rises from January till it reaches the peak in September, then falls to the downhill in December, to the same level as in January.
