| Abstract: | The paper aims to reveal the basic situation of spring weeds in Guangdong tea gardens. From March to May 2020, the weed communities in 620 plots of 31 tea gardens in eastern, western and northern of Guangdong Province were investigated. Seven-level visual observation method was used to record the weed species and growth dominance grade. A total of 313 species of weeds were found. There were 126 species of weeds with a frequency more than 10%, including 23 species of Compositae, 12 species of Gramineae, 8 species of Rubiaceae, 7 species of Rosaceae, 6 species of Labiatae, 5 species of Polygonaceae and 4 species of Leguminosae. The above 7 families contain 65 species of weeds, accounting for 51.5% of the 126 kinds of weed species. The top 10 weed species in the frequency of occurrence were Erigeron canadensis (83.87%), Smilax china (80.65%), Commelina communis (77.42%), Centella asiatica (74.19%), Crassocephalum crepidioides (74.19%), Oxalis corniculata (74.19%), Melastoma dodecandrum (70.97%), Bidens pilosa (70.97%), Viola inconspicua (67.74%), and Emilia sonchifolia (67.74%). The top 10 weed species in terms of growth dominance were Erigeron canadensis (17.42%), Bidens bipinnata (17.19%), Commelina communis (17.10%), Oxalis corniculata (15.11%), Praxelis clematidea (12.58%), Imperata cylindrica (12.19%), Crassocephalum crepidioides (12.06%), Spermacoce alata (10.90%), Oxalis corymbosa (10.65%) and Melastoma dodecandrum (9.81%). There were significant differences in dominant weed species among tea areas in eastern, western and northern of Guangdong. The preponderant weed species in eastern Guangdong were Bidens pilosa, Erigeron canadensis and Microlepia hancei; in western Guangdong were Commelina communis, Praxelis clematidea, Mikania micrantha and Spermacoce alata; in northern Guangdong were Erigeron canadensis, Rubus rosifolius and Imperata cylindrica. This survey preliminarily identified main weed species in spring in different tea areas of Guangdong Province, which would provide data support for the formulation of weed control plans. |
