人为氮输入导致植物对磷的需求增加，植物在富氮环境中的竞争可能取决于其利用土壤磷源的能力。在土壤中，磷主要以不溶性磷酸盐化合物的形式存在，含有三种矿物元素：铁（Fe），铝（Al）或钙（Ca），并且在很大程度上还不清楚入侵植物是否能够获得这种不溶性磷源及其与氮富集的相互作用以获得竞争优势。对入侵植物加拿大一枝黄花（Solidago canadensis L.）培养在可溶性磷酸盐KH 2 PO 4（Ortho-P）和不溶性无机磷酸盐AlPO 4（Al-P）、FePO 4（Fe-P）、Ca 5（OH）（PO 4）3（Ca-P）中。结果表明，S.加氮条件下，加拿大油菜能选择性地利用Al-P中的P，但不能选择性地利用Fe-P或Ca-P中的P。S.在富氮环境下，加拿大大豆利用不溶性磷源的能力是其竞争优势。canadensis在富铝土壤中生长。有效控制S.加拿大入侵可能需要考虑土壤磷管理的背景下，大气氮沉降以及。
Anthropogenic nitrogen (N) inputs lead to the increase of phosphorus (P) demand for plants and plant species competition in a N enriched environment may hinge on its ability to utilize soil P sources. In soils, P mostly exists as insoluble phosphate compounds with three mineral elements: iron (Fe), aluminum (Al) or calcium (Ca), and it remains largely unknown whether invasive plant species are able to access such insoluble P sources and its interaction with N enrichment to gain competitive advantage. We determined the morphological traits, growth and nutrient status of an invasive plant Canada goldenrod (Solidago canadensis L.) cultured in soluble phosphate KH2PO4 (Ortho‐P), and insoluble inorganic phosphate AlPO4 (Al–P), FePO4 (Fe–P), Ca5(OH)(PO4)3 (Ca–P) at three N supply levels. Results showed that S. canadensis was able to selectively utilize P from Al–P but not from Fe–P or Ca–P by increasing root number and length under N additions. The increasing growth in S. canadensis was closely correlated with the increasing foliar P. Ability to utilize insoluble P sources under enriched N environment serves as a competitive advantage for S. canadensis in Al rich soils. Effective control of S. canadensis invasion may need to consider soil P management in the context of atmospheric N deposition as well.
