摘要

对不同生产力（高、中、低产）和种植年限（10、45、100 a）的茶园及与其相邻林地土壤N₂O的排放速率进行了田间原位测定,并探究其与土壤pH、有机碳、总氮、水溶性有机碳氮、微生物生物量碳氮（MBN）、铵态氮和硝态氮等土壤理化性质的关系。结果表明,不同类型茶园间的土壤理化性质有显著差异,且各土壤理化性质之间有一定相关性;不同类型茶园的平均N₂O排放速率（以N计）为3.14 mg·m^-2·h^-1,其中100 a茶园N₂O的排放速率（以N计）为4.47 mg·m^-2·h^-1,显著高于其他茶园;茶园N₂O排放速率是林地的3.1~7.2倍。Mantel检验表明N₂O的排放速率与水溶性有机碳、有机碳、总氮及微生物碳氮呈显著正相关（P<0.05）,线性回归和结构方程模型表明MBN是茶园土壤N₂O排放速率的最显著影响因子。

Abstract

In this study, we measured the in-situ N₂O emission rate in different types of tea gardens including productivity (high, medium and low) and planting years (10 a, 45 a and 100 a) and their adjacent forest, and analyzed the relationships between N₂O emission rate and soil properties including pH, organic carbon, total nitrogen, water-soluble organic carbon and nitrogen, microbial biomass carbon and nitrogen, ammonium nitrogen, and nitrate nitrogen. The results show that different types of tea gardens had significant effects on the changes of soil properties, and there were significant correlations between the soil properties. The average N₂O emission rate (N emission equivalents) in tea gardens was 3.14 mg·m^-2·h^-1, and the highest was in 100 a tea garden with the value of 4.47 mg·m^-2·h^-1. The N₂O emission rates in tea gardens were 3.1-7.2 times higher than that in forest. Mantel test shows that the N₂O emission rate was significantly and positively correlated with water-soluble organic carbon, organic carbon, total nitrogen, and microbial biomass carbon and nitrogen (P<0.05). Linear regression and structural equation models show that microbial biomass nitrogen (MBN) was the most significant factor affecting the N₂O emission rate in the tested fields.
