Global climate change escalates the rise of atmospheric CO₂ concentration and temperature, which impact crop production in agricultural ecosystems. As the second important macronutrient, phosphorus (P) fundamentally mediates the crop adaptability to climate change. An overview on previous work on crop P acquisition and soil P dynamics in responses to elevated CO₂ and temperature would be critical for further advancing our knowledge on P cycling under climate change and its management to maintain agroecosystem sustainability. This review focuses on the effects of elevated CO₂ and temperature on root morphology, root exudation, and associated biochemical properties in the rhizosphere in relevant to crop P acquisition and soil P availability. Studies indicate that elevated CO₂ and temperature could increase P uptake of crops, such as rice and soybean when crops are grown within the range of optimal growth temperature. Elevated CO₂ and temperature not only alter root exudates and changes the activity of soil enzymes and microbes the in rhizosphere environment, but also directly influence soil chemical and biochemical processes and thus the bioavailability of P. It is worth to focus on P-solubilizing microbial community composition, and microbial function on soil P mobilization in the rhizosphere of crops grown under climate change.

全球气候变化加剧了大气中CO ₂浓度和温度的上升，从而影响了农业生态系统中的农作物产量。作为第二种重要的常量营养素，磷（P）从根本上调节了作物对气候变化的适应性。概述先前有关作物P吸收和土壤P动态以应对CO ₂和温度升高的工作的工作，对于进一步提高我们在气候变化下的磷循环及其管理以维持农业生态系统可持续性的知识至关重要。这篇评论着重于CO ₂升高的影响和温度对根际形态，根系分泌物以及根际中与作物磷获取和土壤磷有效性相关的相关生化特性的影响。研究表明，当在最佳生长温度范围内种植农作物时，升高的CO ₂和温度可以增加农作物（例如水稻和大豆）的P吸收。升高的CO ₂和温度不仅改变根际环境中的根系分泌物并改变土壤酶和微生物的活性，而且直接影响土壤的化学和生化过程，从而直接影响P的生物利用度。气候变化下农作物根际土壤微生物组成及其对土壤磷动员的微生物功能
