生物炭改良盐碱地土壤的效应与机制研究进展
Research progress on effects and mechanisms of biochar in improving saline-alkali soil
摘要
Abstract
Because of its poor physical properties,low fertility and fragile ecological environment,saline-alkali land se-riously restricts crop growth.Biochar,as a carbon-based polyporous material produced by pyrolysis of organic matter such as agricultural waste and forestry residues under hypoxia or low oxygen conditions,has the characteristics of high specific surface area,abundant surface functional groups and high porosity.As a new efficient soil amendment,biochar has been studied in improving soil fertility,reducing nutrient loss,improving soil structure and promoting plant growth.This paper reviewed the basic characteristics of biochar and its application in saline-alkali soil improvement.From the per-spectives of improving soil physical structure,increasing soil nutrient content and availability,improving soil moisture condition,activating soil microorganisms and increasing soil cation exchange capacity,the reducing effect and mechanism of biochar on soil obstacle factors in saline-alkali land were expounded.Finally,the future research direction of biochar improvement of saline-alkali land was prospected,and the problems to be solved were put forward,in order to provide the-oretical basis and technical reference for the development and utilization policy of saline-alkali land.关键词
