土体构型对土壤水氮储运的影响研究进展

Effects of Soil Profile Configuration on Soil Water and Nitrogen Storage and Transportation: A Review

土体构型是土壤剖面中不同质地层次的排列、组合状况,其对土壤水分、溶质运移过程和作物生长等均具有显著影响,具有重要的农学和环境意义。本文对该领域的研究动态和最新进展作了综述,重点探讨了土体构型对土壤水分和氮素储存、运动过程的影响机理及其农学效应,并对今后有关土体构型的研究和改良技术的发展趋势进行了展望。

Soil configuration is the arrangement and combination of differently textured soil layers in a profile. This configuration has significant effects on soil water/solute transport and crop growth, and therefore is of fundamental significance in sustainable agriculture and environmental protection. This paper summarized the research progresses and latest achievements in this field, especially the effects of soil configuration on water and nitrogen storage and transport and their agronomic responses. The prospects of the future research on this topic were also presented.
