摘要/Abstract

摘要： 江苏人多地少，沿海滩涂盐碱地是其主要的土地后备资源，滩涂盐碱地开发利用的前提是盐土的快速降盐。笔者从碳管理的角度综述了盐土治理方面的研究成果。盐土改良的3 个技术措施为耐盐植物、改进土壤SOC库的农艺技术以及可溶性盐的淋溶，而重要的农艺技术包括粪肥、作物残茬管理、建立人工林、农林系统、多年生禾草与饲草、营养综合管理等。最后，笔者对江苏沿海滩涂盐土改良与耐盐作物研究策略作了简单的讨论。

Abstract: CoastalStidal landSis the mainSreserve land resources in Jiangsu Province with a large population and relatively little arable land. The prerequisite of exploitation and utilization of tidal land is reducing salt content in saline soils. Relevant results of salt-affected soils amelioration were summarized fromScarbonSmanagement in this paper. Three technological options for reclamation include: (i) use of salt tolerant plants, (ii) agronomic techniques to improve SOC pool, and (iii) leaching of salts. Important approaches among agronomic techniques are manuring, mulch farming with a no-till system, establishing tree plantations or agroforestry systems, growing forages and perennial grasses, and improving soil fertility through integrated nutrient management (INM). At last, investigation strategies for reclamation of salt-affected soils and salt tolerant crop plants were briefly discussed in the paper.
