退化土地是指由于非生物或生物压力而丧失初级生产力的土壤。在非生物胁迫中，干旱、盐碱化和重金属是热带地区的主要威胁。这些压力影响植物生长并降低其生产力。固氮植物，如放线根植物，能够在贫瘠和受干扰的土壤中生长，被广泛种植，用于退化土地的复垦。有研究表明，土壤微生物特别是固氮菌Frankia与放线根植物的结合可以减轻非生物和生物胁迫的不利影响。放线根植物接种法兰克菌可显著提高田间移栽后植株的生长、生物量、地上部和根部氮含量及成活率。然而，在退化地建立放线根菌人工林的成功与否取决于法兰克菌有效菌株的选择。关于法兰克对退化土壤中放线根植物生长的有益作用的研究很少。本文介绍了在恶劣条件下利用Frankia接种提高放线根植物生长性能的实例。
Degraded lands are defined by soils that have lost primary productivity due to abiotic or biotic stresses. Among the abiotic stresses, drought, salinity, and heavy metals are the main threats in tropical areas. These stresses affect plant growth and reduce their productivity. Nitrogen-fixing plants such as actinorhizal species that are able to grow in poor and disturbed soils are widely planted for the reclamation of such degraded lands. It has been reported that association of soil microbes especially the nitrogen-fixing bacteria Frankia with these actinorhizal plants can mitigate the adverse effects of abiotic and biotic stresses. Inoculation of actinorhizal plants with Frankia significantly improves plant growth, biomass, shoot and root N content, and survival rate after transplanting in fields. However, the success of establishment of actinorhizal plantation in degraded sites depends upon the choice of effective strains of Frankia. Studies related to the beneficial role of Frankia on the establishment of actinorhizal plants in degraded soils are scarce. In this review, we describe some examples of the use of Frankia inoculation to improve actinorhizal plant performances in harsh conditions for reclamation of degraded lands.
