能源植物芒草耐盐性研究进展

Research Progress on Salt Tolerance of Energy Plant Miscanthus

近些年,随着耕地面积缩减和土壤盐渍化程度加剧,研究和开发适合在边际土壤尤其是盐碱地种植的作物,对缓解农业生产压力、改良土质和恢复生态环境具有重要的作用。芒草具有投入少、产量高、品质优、多年生、抗逆强等优点,作为能源作物和饲草作物开发利用潜力极大。综述了芒草的种质资源状况、开发利用特点、耐盐特性及耐盐生理等,并对芒草的研究与应用前景进行分析和展望,以期为芒草开发利用提供参考。

In recent years,soil salinization has become an increasingly serious problem limiting agricultural productivity.Research and development of perennial crops that can grow well on marginal land,especially on saline soil,plays an important role not only in relieving agricultural production pressure,improving soil quality but also in restoring ecological environment.Miscanthus has been the optimal candidate for sustainable energy crop and forage crop due to its characteristics of low input,high yield,multi-harvest and high stress tolerance.In this paper,the germplasm resources of Miscanthus,development and utilization characteristics,salt tolerance and its physiological mechanism of Miscanthus were reviewed.Furthermore,the research and application prospects of Miscanthus were analyzed and prospected,in order to provide reference for the development and utilization of Miscanthus.
