摘要:

研究广西主要茶园土壤酸度与交换性氢、铝的关系,为科学种植茶树,改良酸化土壤提供技术支持。采集广西茶树种植区的290个土壤样品,分析其pH值,交换性氢和铝含量。结果显示,广西茶区土壤pH值波动范围较大,为3.11~6.89,66.56 %的土壤样品pH值低于4.5,茶园的土壤酸性极强。pH值越小,交换性酸含量越大。交换性酸是影响土壤pH值的主要因素。当pH值较低时,交换性H+的含量和交换性Al3+的含量会更多。土壤交换性酸与交换性H+和交换性Al3+之间存在显著的线性正相关关系,随着H+和Al3+含量的增加,土壤交换性酸也会相应增加。交换性Al3+对土壤酸度的贡献度大于交换性H+对土壤酸度的贡献度。可见,广西茶园土壤酸化严重,在生产上应适时进行土壤酸性改良。

Abstract:

To study the relationship between soil acidity and exchangeable hydrogen and aluminium in the main tea gardens of Guangxi, and to provide technical support for the scientific cultivation of tea trees and the improvement of acidified soil, 290 soil samples were collected from the tea tree planting areas in Guangxi, and their pH values, exchangeable hydrogen and aluminum contents were analyzed. The results show that the pH value of the soil in the tea-growing areas of Guangxi fluctuates greatly, ranging from 3.11 to 6.89. 66.55% of the soil samples have a pH value lower than 4.5, and the soil in the tea gardens is extremely acidic. The smaller the pH value, the greater the content of exchangeable acids. Exchangeable acid is the main factor affecting soil pH value. When the pH value is low, the content of exchangeable H+ and exchangeable Al3+ will be higher. There is a significant linear positive correlation between soil exchangeable acid and exchangeable H+ and exchangeable Al3+ With the increase of the contents of H+ and Al3+, soil exchangeable acid will also increase accordingly. The contribution of exchangeable Al3+ to soil acidity is greater than that of exchangeable H+ to soil acidity. It can be seen that the soil in tea gardens in Guangxi is severely acidified. In production, soil acidity improvement should be carried out in a timely manner.
