Additional datasets for the effects of biochar-based urea and urea application on soil methane uptake in a subtropical forest

Through a three-year field trial in a subtropical bamboo forest, we explored the responses of soil physicochemical and microbial properties to application of biochar-based urea and urea, and how the biochar-based urea and urea regulated the dynamic changes in soil CH₄ uptake, temperature, water content, WSOC, MBC, NH₄⁺-N, NO₃⁻-N, CH₄ oxidation rate, CH₄ production rate, <em>pmoA</em> gene, <em>mcrA</em> gene, and <em>pmoA/mcrA</em> ratio.

本研究于亚热带竹林开展为期三年的野外定位试验，探究土壤理化与微生物特性对施加生物炭基尿素及普通尿素的响应规律，并解析生物炭基尿素与普通尿素如何调控土壤甲烷吸收、温度、含水量、水溶性有机碳（Water-Soluble Organic Carbon, WSOC）、微生物量碳（Microbial Biomass Carbon, MBC）、铵态氮（NH₄⁺-N）、硝态氮（NO₃⁻-N）、甲烷氧化速率、甲烷产生速率、pmoA基因、mcrA基因及pmoA/mcrA比值的动态变化。
