Abstract

Drought is one of the main problems in the world affecting the yields of plants. Climate change has led to increased droughts affecting food security and sustainable development goals (SDGs) targets. Applying biochar and Arbuscular mycorrhizal fungi (AMF) can effectively increase soil fertility and crop yields under drought conditions. This study highlighted the impact of biochar and AMF on the growth of turmeric, nutrients and physiological properties under drought stress. Turmeric plants were grown under water stress in a net house. Four treatments used for the experiments included control (only soil), biochar, AMF, and combined treatment with biochar and AMF. For the pot experiments, 1% biochar was mixed with soil. AMF contained 100 spores/g and 1200 IP/g. Maximum improvement in rhizome biomass, rhizome number and availability of plant nutrients was observed after the co-application of biochar and AMF. Significant improvement in microbial biomass and AMF spore numbers was also observed in the soil exposed to biochar + AMF. Applying biochar and AMF in combination under water stress significantly enhanced fluorescein diacetate dehydrogenase and alkaline phosphatase activity in the soil compared to control. Results suggested that co-supplementation of biochar and AMF can promote soil nutrients along with turmeric's growth parameters and physiological properties in water stress.

生物炭和 AMF 可改善干旱胁迫下姜黄的生长、生理性状、营养成分和土壤生化特性

干旱是世界上影响植物产量的主要问题之一。气候变化导致干旱加剧，影响粮食安全和可持续发展目标（SDGs）的实现。在干旱条件下，施用生物炭和丛枝菌根真菌（AMF）可有效提高土壤肥力和作物产量。本研究强调了生物炭和 AMF 在干旱胁迫下对姜黄生长、养分和生理特性的影响。姜黄植株在水胁迫下生长在网室内。实验采用了四种处理方法，包括对照（仅土壤）、生物炭、AMF 以及生物炭和 AMF 混合处理。在盆栽实验中，1% 的生物炭与土壤混合。AMF 含有 100 个孢子/克和 1200 个 IP/克。在同时施用生物炭和 AMF 后，根茎生物量、根茎数量和植物养分的可用性得到了最大改善。在施用生物炭和 AMF 的土壤中，微生物生物量和 AMF 孢子数量也有显著提高。与对照组相比，在水分胁迫条件下同时施用生物炭和 AMF 能显著提高土壤中荧光素二乙酸脱氢酶和碱性磷酸酶的活性。结果表明，在水胁迫条件下，生物炭和 AMF 的共同补充可促进土壤养分以及姜黄的生长参数和生理特性。
