文摘

Effects of nutrient input on Alternanthera philoxeroides were similar between monoculture and mixed culture. Under low nutrient level, effects of N/P ratio on invasive plant growth would be negligible. Nutrient level, rather than N/P ratio, affected the competitive dominance of Alternanthera philoxeroides. Nutrient level cannot alter crucial effects of co-occurring species on the competitive dominance of Alternanthera philoxeroides.
