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%的土壤不适宜种植茶树。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,相关系数分别在0.912-0.952和0.898-0.973之间。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。(图1 表6 参27)
Abstract:
In order to explore the effect of tea tree rhizosphere soils acidification on yield and quality of tea tree, the pH value, yield and quality index of fresh tea leaves with different ages were analyzed, and the correlation between rhizosphere soils acidification and ages, yield and quality indexwere revealled from 9 tea plantations in Anxi county, Fujian province. The results showed that 37.67% of the 9 soil has been acidified and 10.03% of them is not suitable for planting tea tree. Furthermore, the results indicated that the tea tree age was significantly and negatively correlated with the pH value, as showed that the soil pH value decreased with the age. And yield of spring and autumn tea of the 9 tea plantation were all significantly and positively correlated with the pH value, and correlation coefficients were distributed in 0.912-0.952 and 0.898-0.973, respectively. In addition, quality index including polyphenols, theanine, and caffeine in the 9 tea plantations were all significantly and positively correlated with the pH value, and correlation coefficients were distributed in 0.897-0.959, 0.908-0.974 and 0.907-0.975, respectively. In brief, as the tea tree age increased, the rhizosphere soil acidity of tea tree was significantly increased, and the yield and quality of tea presented significant updown trend.
