| Abstract: |
| In order to understand the competitive effect between Galinsoga parviflora and Trifolium repens, a greenhouse
competition experiment was conducted with invasive plant G.parviflora and T.repens, with different densities and proportions
of combination, to investigate their competitive behavior and the growth response, and relative competitive ability was
evaluated. The results were as follows: The relative competitive ability of G.parviflora was higher than this of T.repens in the
mixed planting. The individual biomass of G.parviflora and T.repens decreased as the density enhanced with monoculture
and mixed planting in different densities. The RY value of G.parviflora was significantly greater than 1, however, the PYT
value of G.parviflora was not significantly greater than 1, the A value of G.parviflora was significantly greater than zero of all
test densities, when mixed planting and monoculture, indicating that the competitive ability of G.parviflora was stronger than
T.repens. The density, proportion, density proportion had no significant effect on competitive ability between G.parviflora
and T.repens. |
