摘要:
土壤保墒性能与土壤水分有效性多年来一直是土壤物理学领域中最为活跃的研究课题之一,也是半干旱地区农业研究中迫切需要解决的问题.土壤水分是植物需水的主要来源,其保蓄和储存在一定程度上决定于土壤的保墒性能.而植物从土壤中吸水的容易程度决定于土壤水分有效性.随着SPAC理论的发展,土壤与植物水分关系的概念已发生了根本变化;本文拟将土壤保墒性能与土壤水分有效性研究进展做一综述.
Abstract:
Soil capability of preserving moisture and soil water availability have been the interesting topics in the area of soil phsics for many years,and a problem to be needed to solve in agricultural re search in the arid area as well.Soil water is the main source of the plant water demand,its preserving and saving depend on the soil capability of the preserving moisture,and the easy degree of the soil water absorption by plant is determined by the soil water availability,With the development of the SPAC theory,a fundamental change has taken place in the conception of soil-plant-water relationships,this paper gives a review of the studies.
