摘要
盐碱土因碱性高、透气性差透水性差、表面容易板结、养分含量低、含有害盐分等导致植物生长受到限制,但是国家粮食安全战略则要求必须加大力度"向盐碱地要粮".大量研究证明,适宜浓度木醋液可以有效改善盐碱土理化性状,从而提高盐碱土生产力.文章列举了不同种类木醋液理化性质和成分含量,描述了木醋液施用浓度的范围,总结了木醋液施入盐碱土后,土壤物理、化学、微生物、酶活性以及植物生长情况的变化,以为木醋液应用于盐碱土壤中提供理论参考.
Abstract
Saline soil has limited plant growth due to its high alkalinity,poor air permeability,poor water permeability,easy surface hardening,low nutrient content,and harmful salt content.However,the national food security strategy requires greater efforts to"request food from saline soil land".A large number of studies had proved that the appropriate concentration of wood vinegar could effectively improve the physical and chemical properties of saline soil,thereby increasing its productivity of saline soil.The article listed the physical and chemical properties and component contents of different types of wood vinegar,described the range of application concentrations of wood vinegar,and summarized the changes in soil physics,chemistry,microorganisms,enzyme activities,and plant growth after wood vinegar was applied to saline-alkali soil,so as to provide a theoretical reference for the application of wood vinegar in saline soil.
