摘要：

Crop rotation and high intensity of cereals can influence the spectrum and intensity of weed species. The weed infestation of spring barley crop and winter wheat crop was monitored at the field trial based on three crop rotation systems, carried out in year 2009 and 2010. The first variety of the crop rotation system has a 33.3% share of cereal crops, second variety with 50% of cereal crops share and the third variety with 66.66% cereal crops share. The results were processed by Canonical Correspondence Analysis, CCA. Regarding winter wheat crop at 33.3% cereal crops share, the most frequent weed species were Fallopia convolvulus, Lamium amplexicaule a Medicago sativa. At the 50% and 66.66% cereal cropss share varieties, the most frequent weed species were Galium aparine a Viola arvensis.
