摘要:

分析1,2代马尾松林地土壤pH值和不同形态铝含量。结果表明: 土壤pH值随林龄增加和连栽而下降; 交换性铝和可溶性铝含量均随林龄增加和连栽而增加; 腐殖酸铝和有机络合态铝含量随连栽而降低; 单聚体羟基铝和酸溶无机铝含量无明显变化规律,且对土壤酸化影响不大。

关键词: 马尾松, 连栽, 铝形态, pH

Abstract:

pH and aluminum content in different forms in the soil of the 1st and 2nd generation Pinus massoniana plantations were investigated. The results showed that pH decreased with the stand age and successive rotation increase. Both the exchangeable aluminum and the soluble aluminum content increased with the stand age and successive rotation increase. Humic acid aluminum and organic complexation state aluminum decreased with the increase of successive rotation. Hydroxy monomer aluminum and acid soluble inorganic aluminum had no significant change, and had little effect on soil acidification.

Key words: Pinus massoniana, successive rotations, aluminum forms, pH
