摘　　要：为揭示茶树根际土壤酸化对茶叶产量、品质的影响,以福建省安溪县9个乡镇茶园为研究对象,分析不同树龄茶树根际土壤的pH值、茶树鲜叶的产量和品质指标含量并分析土壤酸度与茶树树龄、茶树鲜叶的产量和品质的关系.结果表明,安溪县9个乡镇茶园中,37.67%的土壤已经酸化,10.03%的土壤适宜种植茶树.茶树树龄与其根际土壤pH值呈极显著负相关,即随着茶树树龄的增加,其根际土壤pH值呈现下降趋势.其次,9个乡镇茶园春茶、秋茶产量均与茶树根际土壤pH值呈极显著正相关,相关系数分别为0.912-0.952和0.898-0.973.此外,9个乡镇茶园茶叶品质指标——茶多酚、茶氨酸、咖啡碱均与茶树根际土壤pH值呈极显著正相关,相关系数分别在0.897-0.959、0.908-0.974和0.907-0.975之间.综上表明,随着茶树树龄的增加,茶树根际土壤酸度加剧,茶叶产量降低,茶叶品质呈现下降趋势.In order to investigate the effect of tea tree rhizosphere soil acidification on yield and quality of tea tree, the pH value, yield, and quality index of fresh tea leaves of different ages were analyzed, and the correlation between rhizosphere soil acidification and ages, yield, and quality index were studied from nine tea plantations in Anxi county, Fujian Province. The results showed that 37.67% of the nine soils were acidified, and 10.03% of them were suitable for planting tea tree. Furthermore, the results indicated that the age of tea tree was significantly and negatively correlated with the soil pH value, as shown by a decrease in soil pH values associated with an increase in tree age. In addition, the yield of spring and fall crops of tea from these nine plantations were all significantly and positively correlated with the pH value, with correlation coefficients distribution values of 0.912–0.952 and 0.898–0.973, respectively. In addition, quality indices, including polyphenols, theanine, and caffeine for the nine tea plantations were all significantly and positively correlated with their soil pH values, and their correlation coefficient distribution values were 0.897–0.959, 0.908–0.974, and 0.907–0.975, respectively. Above all, as tea tree ages increased, rhizosphere soil acidity was significantly increased, and yield and quality of tea presented a statistically significantly up/down trend.
