IntroductionCamellia japonica is a broad-leaf evergreen tree that is naturally distributed in coastal areas of the southern parts of Korea (Park et al., 2017). This tree constitutes an important type of coastal vegetation in Korea because the tree is relatively tolerant to sea breeze and salinity. However, most C. japonica forests in the coastal areas of Korea have been degraded due to human activities such as road construction, urban development, and seedling collections for potted planting. The Korean government has made efforts to restore C. japonica forests in coastal areas, but restoration is very difficult (Park et al., 2017). In coastal environments, plant growth and survival are affected by the salinity of the soil and by the low availability of nutrients (Williams et al., 1998;Weber and D' Antonio, 1999). In particular, excess salt in the soil can decrease plant growth by inhibiting the osmotic uptake of water by roots or by causing nutritional imbalance through competitive ion absorption (Koyro, 2006).Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance plant growth by a wide variety of mechanisms including phosphate solubilization, siderophore production, biological nitrogen fixation, rhizosphere engineering, phytohormone production, and interference with pathogen toxin production. The potentiality of PGPR in agriculture and forestry is steadily increased as it offers an attractive way to replace the use of chemical fertilizers, pesticides, and other supplements (

The objective of this study was to determine the effect of single and co-inoculation of plant growth promoting bacteria (PGPB) on early plant growth in Saemangeum reclaimed soil. Plant growth promoting Brevibacterium iodinum RS16 and Methylobacterium oryzae CBMB20 were inoculated on maize (Zea mays L.) and sorghum-sudangrass hybrid (Sorghum bicolor L.) grown in Saemangeum reclaimed soil. Single and co-inoculation of B. iodinum RS16 and M. oryzae CBMB20 increased plant height, dry biomass accumulation and macro-nutrient accumulation of maize and sorghum-sudangrass hybrid. M. oryzae CBMB20 treatment increased plant height in maize by 41.2% at 30 days after sowing (DAS), shoot dry weight and total dry weight compared to non-inoculated treatment. Macro-nutrient accumulation (N and P) in maize roots was significantly increased with co-inoculation treatment, K and Ca content was significantly increased at B. iodinum RS16 treatment compared to non-inoculated treatment. Macro-nutrient accumulation (P, K, Ca and Mg) in shoot was higher with M. oryzae CBMB20 treatment compared to non-inoculated treatment. In case of sorghum-sudangrass hybrid, co-inoculation treatment showed 33.7% increase in plant height compared to non-inoculated treatment at 30 DAS. M. oryzae CBMB20 treatment increased root dry weight and total dry weight, macro-nutrient accumulation in roots and N, Ca and Mg accumulation in shoot compared to non-inoculated treatment. P and K accumulation in shoot was significantly increased at co-inoculation treatment compared to non-inoculated treatment. This pot culture experiment demonstrated that single and co-inoculation of B. iodinum RS16 and M. oryzae CBMB20 increased the early growth and nutrient accumulation of maize and sorghum-sudangrass hybrid.Key words: Brevibacterium iodinum RS16, Maize, Methylobacterium oryzae CBMB20, Saemnangeum reclaimed soil, Sorghum-sudangrass hybrid Effect of co-inoculation of Brevibacterium iodinum RS16 and Methylobacterium oryzae CBMB20 on the early growth of crop plants in Saemangeum reclaimed soil 2

Abstract:Reclamation changes the characteristics of water movement, then affects the marine environment system, and may even lead to environmental disasters. The influence on the 4 aspects of the current field, wave field, suspended sediment field and topography were summarized. Impacts of large area of reclamation project on the marine environment are found very few, and to expand the study scope and make up for the current lack of a wide range of studies on multiple reclamation impacts on the marine environment is an important research direction in the future; In the long time scale, it is a lack of long-term cumulative effects on coastal reclamation and whether the influence can restore; the present study focuses only on the impact evaluation of scope, type, and degree from lack of exploring the potential mechanism; It is a lack of interdisciplinary research, and the analysis of comprehensive influence of reclamation projects on land, sea and biological and ecological environment.Keywords: Reclamation, Offshore, Hydrodynamic, Water and Sediment Environment PrefaceReclamation refers to an engineering technology of building dike to settle along the river, lakeside and seaside. Coastal development was dominated by farmland and aquiculture in early reclamation whose proportion reduced relatively in medium term, and the proportion of port and urban construction with high economic value increased gradually in late development [1][2][3]. Reclamation has become an important measure to solve the contradiction between man and land and promote economic development in the coastal areas. Based on remote sensing and GIS technology, the total amount of reclamation shows a trend of decreasing first and then increasing in the past 1985-2010 years in China. Among them, reclamation intensity of the Bohai rim economic circle and the Yangtze River Delta Economic Zone was the largest whose total amount of reclamation accounted for 85.7% of the whole country [4]. The coastal reclamation intensity growth rate in the case study areas of Yellow River estuary from 2000 to 2015 is about 37.97% [5].Because of China's rapid growth of reclamation area [6], coastal zone suitable for reclamation reduce drastically [7], and the focus of reclamation is gradually from the high to middle and low beaches which also fall sharply [8]. The reclamation project changes the hydrodynamic conditions and marine sediment conditions, which produce the change of tide flow field and deposition. And the greater reclamation area is, the greater the effect of hydrodynamic conditions are [9]. The impact on coast erosion, seabed topography, port and waterway siltation, estuary deposition, bay tidal volume and coastal beach stability and ecosystem [10][11][12][13] near reclamation project will be brought [14][15][16][17][18][19][20][21], which will be more and more serious [22] and aggravate the flood disaster in some areas in a certain extent [23].Aiming at the present reclamation situation of Jiangsu in China, Zhang C K, et al. [24] proposed the development of c...
