补血草属植物种间竞争试验

Experiment on Interspecific Competitions Between Limonium Species

以天津地产的中华补血草、二色补血草和外地引入的德国补血草、黄花补血草为试材,混合播种后采用输入比率和输出比率对比分析的方法,研究了4种补血草之间种间竞争的关系。结果表明:地产的2个物种处于竞争优势,引进的2种补血草的表现不同,1种可与当地物种保持平衡状态,另1种处于被排挤的地位。

Taking Tianjin native species of Limonium sinense ,L. bicolor and introductive species of L. tataricum and L. aureum as materials, interspecific competitions between four Limonium Mill species were studied with the analysis of input and output ratios between the two species by mixed sowing. The results showed that the two native species played a dominant role in the competitions while the other two introductive species had different performance,one could be in the balanced state with the native species and the other one was at disadvantage position.
