研究了红壤不同利用方式对铝的活性和形态的影响。结果表明：四种活性铝的提取剂对土壤中铝的提取力顺序一般为０．５ｍｏｌ／ＬＮａＯＨ＞１ｍｏｌ／ＬＨＣｌ＞１ｍｏｌ／ＬＮＨ４Ａｃ＞１ｍｏｌ／ＬＫＣｌ。发育于第四纪红色粘土、采自同一地点、水文环境相似的黄筋泥的利用方式不同，活性铝含量相差极大，特别是交换性Ａｌ３＋的大小顺序（×１０－６）是：荒地（７４０）＞茶园（６６３）＞桃园（４３２）＞桔园（２３４）＞水稻田（１２７）。土壤中水溶性铝含量对土壤酸度十分敏感。
The effects of different utilization ways of red soil on the activity and morphology of aluminum were studied. The results showed that the extraction order of aluminum from four kinds of active aluminum in soil was generally 0.5mol / L NaOH> 1mol / LHCl> 1mol / LNH4Ac> 1mol / L KCl. Developed in the Quaternary red clay, the utilization of the yellow gluten mud collected from the same place and the same hydrological environment is different, the content of active aluminum varies greatly, especially the order of size (× 10-6) of exchangeable Al3 + is: 740)> Tea Plantations (663)> Taoyuan (432)> Orange Garden (234)> Paddy Field (127). Soil water-soluble aluminum content of soil acidity is very sensitive.
