Abstract:
To investigate the effect of Ambrosia trifida L.competition on growth and development of soybean，planting density of 0，0.08，0.32 plant m-2Ambrosia trifida L.were adopted under two herbicides treatments.Results showed Ambrosia trifida L.had significant inhibiting effect on the soybean morphological indexes including plant height，branches and biomass.Plant height was shorter under the application of herbicide.Under the application of herbicides，branches were increased gradually at seedling，while showed increase and then decrease trend at podding as the density of Ambrosia trifida L increased.During blooming and podding，plant weight increased firstly and then decreased as the density of Ambrosia trifida L.increased.The root weight of soybean increased firstly and then decreased as the density of Ambrosia trifida L.increased except at blooming stage with herbicides.Results suggest applying herbicide could control giant ragweed in soybean field.
