基于铝化学行为的土壤酸化与调控研究
Researches on Soil Acidification and Its Regulation Focusing on Aluminum Chemical Behaviors
摘要
Abstract
The problem of farmland acidification in China is widespread throughout the country,except for the arid northwest region.The situation is particularly prominent in the tropical and subtropical regions of the south and the black soil area of the northeast,causing serious harm to agricultural production and the ecological environment.This article summarized the main progresses made in aluminum activation during soil acidification,the toxicity of soil active aluminum to plants and ecosystems,and the hydrolysis and transformation of active aluminum during amelioration of acidic soils.The shortcomings of related researches were analyzed and several aspects that should be focused on in future research were proposed.Emphasis should be placed on strengthening the research on the mechanisms of aluminum activation during soil acidification,the mechanisms of aluminum hydrolysis and the characteristics of aluminum hydrolysis products during the amelioration of acidic soils,which will provide theoretical basis for the management of acidified farmland and the sustainable utilization of acidic soil resources.关键词
