Trait‐Mediated Competition for Light Underpins Plant Diversity Loss Under Eutrophication

Global Change Biology, Volume 31, Issue 9, September 2025.
Eutrophication often reduces plant diversity by making the ground layer darker, which reduces understory plants. In a natural alpine grassland, we added LED light beneath the canopy and saw diversity return across different nutrient treatments: with added nitrogen fertilizer, light mainly increased new species; with added phosphorus fertilizer, it ...

Wild Cicer species exhibit superior leaf photosynthetic phosphorus‐ and water‐use efficiencies compared with cultivated chickpea under low‐phosphorus conditions

New Phytologist, Volume 247, Issue 1, Page 144-159, July 2025.
Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven

Plant nutrient‐acquisition strategies contribute to species replacement during primary succession

Journal of Ecology, Volume 113, Issue 4, Page 988-1003, April 2025.
Pioneer species Hippophae acquires phosphorus and nitrogen mainly by ‘mining’ and N2‐fixing strategies and thus dominates in the beginning of primary succession. As soil nutrient availability increases with the mobilization of apatite‐P and input of N‐rich plant residues, Hippophae' strategies become less efficient than Populus's scavenging strategies.

Variation in leaf phosphorus fractions reflects plant adaptations and distribution in low‐phosphorus tropical forests

Functional Ecology, Volume 39, Issue 2, Page 621-634, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tropical forests are generally characterized by high species diversity and low soil phosphorus (P) availability. Although tropical plants have evolved adaptations to low soil P availability, we know relatively little about the strategies of different groups of species ...

微晶化磷矿粉的发酵活化效应

Shuitu Baochi Xuebao, 2011
选用天然风化煤和pH 3.63的酒厂废弃物酒糟、MV菌剂为活化剂,与PB、PC微晶化磷矿粉在30℃下发酵研究对枸溶性磷的活化效果。结果表明,MV菌剂促进微晶磷矿粉有效P的溶解,且磷矿粉变细解磷效果增强;酒糟、风化煤促进微晶磷矿粉有效磷的溶解;MV菌条件下的酒糟、风化煤有利于微晶磷矿粉的活化,有效磷含量在25d达最高;酒糟对微晶磷矿粉的活化效应2∶1>1∶1,25d枸溶性磷J6、J8、J2和J4分别比对照J净增长了1.63%,1.42%,1.32%及1.22%;MV菌条件下风化煤参与的发酵,25d处理F6、

不同种植年限苹果园土壤磷状况和无机磷组分特征

Shuitu Baochi Xuebao, 2020
通过采集胶东地区不同年限苹果园0—100 cm土层土壤，分析了不同种植年限苹果园土壤全磷、有效磷、无机磷含量和无机磷组分特征，以期为苹果园科学施用磷肥提供依据。结果表明：胶东地区苹果园0—40 cm土层土壤全磷、无机磷、有效磷平均含量为0.76 g/kg，681.10 mg/kg，73.05 mg/kg。种植年限显著影响了苹果园土壤磷含量，随着种植年限的增加耕层土壤全磷、有效磷和无机磷含量呈上升趋势。不同种植年限的苹果园土壤全磷、有效磷及各无机磷组分均随着土层的加深整体呈递减趋势。无机磷组分主要以Al ...

Why are some invasive plant species so successful in nutrient‐impoverished habitats in south‐western Australia: A perspective based on their phosphorus‐acquisition strategies

Functional Ecology, Volume 39, Issue 2, Page 635-652, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Invasive plants are a major cause of the global biodiversity crisis; it is therefore crucial to understand mechanisms that contribute to their success. South‐western Australia is a global biodiversity hotspot with extremely low soil phosphorus (P) concentrations.

紫色土减磷配施有机肥的磷肥效应与磷素动态变化

Shuitu Baochi Xuebao, 2016
为探索长江上游稻油轮作系统减少农田磷素流失和有效提高磷肥利用率的最佳施肥模式，降低磷对水体富营养化的影响，采用长期田间定点试验并结合室内试验分析，研究了化肥配施猪粪和水稻秸秆还田对紫色土磷肥效应及磷素迁移的影响。结果表明：在常规作物施肥基础上配合施用有机肥，适当减少化学磷肥施用量，对作物产量没有显著的减产效应，且能在一定程度上减少农田磷素损失，提高磷肥利用率。水稻磷肥利用率总体表现为常规施磷量减20%+猪粪有机肥（MDP）＞常规施磷量减20%+秸秆还田（SDP）＞常规施肥+猪粪有机肥（MP）＞常规施肥 ...

Changing plant phosphorus acquisition strategies in relation to altered soil phosphorus fractions after wetland drainage

Functional Ecology, Volume 38, Issue 11, Page 2433-2446, November 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phosphorus (P) acquisition strategy is considered to be an intrinsic driver behind plant succession. However, variations in plant P acquisition strategies in connection to soil P fraction changes after wetland drainage remain unclear.

不同土地利用方式对棕壤及其各级微团聚体中有机磷组分的影响

Shuitu Baochi Xuebao, 2007
采用Bowman-cole有机磷分级法研究了典型棕壤及其各级微团聚体中有机磷组分在林地、柞树林地、耕地3种土地利用方式下的变化情况.结果表明,有机磷总量在3种利用方式下表现为林地＞耕地＞柞树林地,有机磷占全磷的比例却为林地＞柞树林地＞耕地.土地利用方式对棕壤活性有机磷和高稳性有机磷的含量及有效性影响甚微,开垦为耕地可保持中活性有机磷含量并提高其有效性,开垦为柞树林地则显著降低其含量,耕垦可显著降低耕地中中稳性有机磷含量及其比例.耕垦可以降低有机磷总量在各级微团聚体中的含量,且降低率随粒级的增大而增加 ...
