| 原文摘要 | There are potentially large benefits to using biochar in temperate, agricultural soils; it may stably sequester carbon and improve crop access to water. However, biochar addition will change the chemical and physical properties of soil and thus influence roots and mycorrhizal fungi. There are now many studies documenting effects of biochar on various aspects of the arbuscular mycorrhizal symbiosis. However, because each study is idiosyncratic, it seems a rather fruitless exercise to document the many context-specific cases in which biochar affects various aspects of the mycorrhizal symbiosis. Instead, I first review some of the effects biochar has on soil properties and how those soil properties influence mycorrhizal fungi and mycorrhizal colonization. Second, because biochar alleviates some of the same stresses experienced by plants that mycorrhizal colonization alleviates, I document ways in which the effects of biochar on plant stress are likely to influence plant response to mycorrhizal colonization. |
