“…The addition of organic fertilizer will change soil physical and chemical properties, and also improve soil enzyme activity 42 . These changes in soil environment are closely related to the structure of microorganisms 43,44 . Besides, the application of organic fertilizer will inevitably affect the nutrient content of soil.…”

Aiming at revealing the possible mechanism of its growth promoting effect on tomato, the correlations among Streptomyces sp. TOR3209 inoculation, rhizobacteriome, and tomato growth/production traits were investigated in this study. By analyses of Illumina sequencing and plate coating, differences in rhizosphere microbial communities were found in different growth stages and distinct inoculation treatments. The plant biomass/fruit yields and relative abundances of families Flavobacteriaceae, Sphingobacteriaceae, Polyangiaceae and Enterobacteriaceae in treatments T (tomato inoculated with TOR3209) and TF (tomato inoculated with TOR3209 + organic fertilizer) were higher than that in the controls (CK and CK+ organic fertilizer), respectively. The analysis of Metastats and LEfSe revealed that the genera Flavobacterium and Sorangium in seedling stage, Klebsiella in flowering stage, Collimonas in early fruit setting stage, and genera Micrococcaceae, Pontibacte and Adhaeribacter in late fruit setting stage were the most representative rhizobacteria that positively responded to TOR3209 inoculation. By cultivation method, five bacterial strains positively correlated to TOR3209 inoculation were isolated from rhizosphere and root endosphere, which were identified as tomato growth promoters affiliated to Enterobacter sp., Arthrobacter sp., Bacillus subtilis, Rhizobium sp. and Bacillus velezensis. In pot experiment, TOR3209 and B. velezensis WSW007 showed joint promotion to tomato production, while the abundance of inoculated TOR3209 was dramatically decreased in rhizosphere along the growth of tomato. Conclusively, TOR3209 might promote the tomato production via changing of microbial community in rhizosphere. These findings provide a better understanding of the interactions among PGPR in plant promotion.

“…The costal mud flat in Dafeng Nature Reserve is the central part of this area, which keeps growing by 50-200 m per year towards the Yellow Sea. The area is under the influence of the northern subtropical monsoon climate, with a mean annual temperature of 15°C and a mean annual rainfall of 1058 mm (Long et al 2016;Li et al 2018;Jiang et al 2019). Halophytic vegetation like Arundo donax (Poaceae) and Suaeda salsa (Chenopodiaceae) are the pioneer plants on this saline soil, followed by the common reed Phragmites australis (Poaceae) mixed with cogongrass Imperata cylindrica (Poaceae), which are the dominant species after the salinity drops (Li et al 2018).…”

“…The rhizosphere soil samples were then stored separately in sterilized bags and transported to the laboratory on ice. Soil chemical properties, including organic matter (OM) content and available phosphorus (AP), were measured as described in our previous study (Jiang et al 2019). Soil pH and electrical conductivity (EC) were measured in a 1 : 5 (w/v) suspension at 25°C.…”

Aims: Sustainable agriculture requires effective and safe biofertilizers and biofungicides with low environmental impact. Natural ecosystems that closely resemble the conditions of biosaline agriculture may present a reservoir for fungal strains that can be used as novel bioeffectors. Methods and Results: We isolated a library of fungi from the rhizosphere of three natural halotolerant plants grown in the emerging tidal salt marshes on the southeast coast of China. DNA barcoding of 116 isolates based on the rRNA ITS1 and 2 and other markers (tef1 or rpb2) revealed 38 fungal species, including plant pathogenic (41%), saprotrophic (24%) and mycoparasitic (28%) taxa. The mycoparasitic fungi were mainly species from the hypocrealean genus Trichoderma, including at least four novel phylotypes. Two of them, representing the taxa Trichoderma arenarium sp. nov. (described here) and T. asperelloides, showed antagonistic activity against five phytopathogenic fungi, and significant growth promotion on tomato seedlings under the conditions of saline agriculture. Conclusions: Trichoderma spp. of salt marshes play the role of natural biological control in young soil ecosystems with a putatively premature microbiome. Significance and Impact of the Study: The saline soil microbiome is a rich source of halotolerant bioeffectors that can be used in biosaline agriculture.

“…Salinization is a worldwide problem and is particularly acute in semi-arid areas. The area of salinized soil in the world is about 9.55 × 10 8 hm 2 , among which the salinized soil area accounts for about 3.78% of the total area in China [1,2], most of which is distributed in arid and semi-arid areas of China [3]. The stability of an oasis ecological environment is related to the survival of humans, social stability, and sustainable development of the economy in the whole arid area.…”

“…The objectives of this paper are the following: (1) to explore the spatial distribution characteristics of soil salinity and moisture; (2) to identify the influential factors of spatial variation of soil salinity and moisture; and (3) to determine the interaction between factors affecting the spatial distribution of soil salinity and moisture in a typical agricultural irrigation area of the oasis in an arid area. Finally, we provide a reference for comprehensively mastering the degree and distribution of salinization, the prevention of salinization, and the stable agricultural production and sustainable development of oasis agriculture.…”

Soil salinization is a global problem, which threatens agricultural productivity and sustainability, especially in arid and semi-arid regions. Soil salinity and moisture are important factors affecting agricultural production in arid regions. However, few studies have considered the influence of topographic factors on the spatial distribution patterns of soil salinity and moisture. This research aims to explore the spatial distribution characteristics and its influencing factors of soil salinity and moisture in the oasis farmland of arid areas. In this paper, GIS and geostatistics methods were applied to analyze the spatial distribution characteristics and variability of soil salinity and moisture, and then the corresponding proxy variables were used to quantitatively study the influence factors by using the geographical detector model. The results showed the coefficients of the variation of soil salinity and moisture to be 71.25% and 31.89%, respectively. There was moderate spatial autocorrelation of soil salinity and moisture. Soil salinity in the southwest was higher than in the northeast, and soil moisture in the northwest and southeast were lower than in the center and the northeast edge. The main influencing factors were available phosphorus, roughness of terrain, alkaline nitrogen, available potassium, and elevation. Combined action of topographic factors and soil nutrients has a major influence on the spatial distribution of soil salinity and moisture. Therefore, developing a suitable fertilizer regime under different topographic conditions could be an effective way to promote the sustainability of oasis agriculture in arid areas.
