In order to investigate the species and distribution of the weeds in kenaf fields in Xinyang area, to find out the dominant populations and the damage degree , and to provide a basis for developing an integrated control method , an experiment which was called an inverted W -9 point sampling method was being executed for two consecutive years.The investigation showed that there were 34 species of weeds belonging to 15 families in this region.And 22 species belonging to 7 families, which were heavily harmful, and accounting for 64.71%of the weeds.There were 27 dicotyledonous weeds accounting for 79.41%, 7 monocotyledonous weeds , accounting for 20.59%, 22 annual weeds , accounting for 64.71%, 5 annual or biennial weeds , accounting for 14.71%, and 7 perennial weeds , accounting for 20.59%.Xi county ranked the highest weed amounts , reaching for 284 plants/m2 , the experimental field of Academy of Agricultural Sciences was the lowest , reaching 85 plants/m2.The abundant species of weeds was unite field which had 16 species.Cyperaceae and Mollugo pentaphylla L.with the highest A and F were regarded as the dominant populations.
