茶树与土壤有机碳测定跨标准比较研究
Cross-standard Comparison of Organic Carbon Determination in Tea Plants and Soils
摘要
Abstract
A comparative study was conducted on the adaptability and stability of three standards,namely GB/T 30733-2014,HJ 615-2011,and NY/T 1121.6-2006,for determining total carbon(TC)and organic carbon(OC)in tea plant leaves,branches,roots,rhizosphere soil,and 0～15 cm surface soil.The analysis focused on the variability boundaries and comparability among the methods.Based on measured results,it was found that for in plant organ samples,HJ 615-2011 and NY/T 1121.6-2006 exhibited systematically lower values compared to GB/T 30733-2014.For soil samples,the differences among the three standards were relatively smaller,although an overall inter-batch level shift was observed.It was concluded that GB/T 30733-2014 demonstrated higher accuracy and precision under cross-medium conditions and is suitable for establishing a unified parameter system for carbon-stock estimation.HJ 615-2011 and NY/T 1121.6-2006 showed certain applicable for soil analysis,but their results should not be directly equated with TC.To ensure cross-standard comparability,conversions or correction based on paired data is recommended.Due to limitations in soil sample and batch structure,cross-batch comparisons are preferably presented in a descriptive manner.关键词
