摘要

Phosphorus (P) is a vital nutrient in agricultural systems, crucial for plant growth and development. Despite its importance, P availability in soil often limits crop yield due to inefficient usage and environmental losses, such as eutrophication caused by excessive fertilizer application. This issue underscores the need for sustainable nutrient management strategies to enhance P bioavailability and retention in agricultural soils. The objective of this study is to explore strategies to improve P bioavailability and retention in agricultural systems, using 109 plant species with high P-accumulation potential. The study focuses on enhancing phosphorus use efficiency (PUE) and leveraging plant–microbe interactions to optimize P-cycling in agroecosystems. The United States Department of Agriculture’s Dynamic Accumulator and Analysis databases were mined for plants with high P accumulation capacity and PUE. From 704 plants listed with high P potential, 109 species with P accumulation above 1000 ppm were selected for a detailed study of their P uptake mechanisms. A comprehensive literature synthesis was conducted on these plant species to identify and integrate reported traits and plant–microbe strategies associated with enhanced soil P bioavailability and retention. The study found that weedy/wild species, which constitute a significant portion of P-accumulating plants, are particularly effective at P uptake and have high PUE due to their adaptability to nutrient-poor conditions and interactions with soil microbes. High P retention is mainly observed in plant roots, with deep taproots enhancing access to deeper soil layers and P reserves. In thirty-five species, arbuscular mycorrhizal fungi constitute the primary mechanism for phosphorus acquisition, highlighting the fundamental role of mycorrhizal symbioses in plant nutrition. Integrated nutrient management practices, such as intercropping, crop rotation, and green manure application, can support soil microbial communities and reduce reliance on synthetic chemical fertilizers. These strategies can significantly enhance P sustainability in agroecosystems. This study demonstrates that by leveraging plant–microbe symbiosis, incorporating plants with high P retention and PUE, as well as adopting tailored integrated nutrient management strategies, farmers can enhance P management, reduce environmental degradation, and promote sustainable agricultural productivity. Integrating plants with high P accumulation potential into agroecosystems can also contribute to food security and foster more sustainable and environmentally friendly farming practices.
