Background: Apple replant disease (ARD) is a common occurrence in many major apple-growing areas worldwide, seriously hindering the development of the apple industry. To avoid the shortcomings of chemical fungicides currently used to control ARD, it is necessary to find sustainable and effective control methods. Here, an endophytic phloridin-degrading Bacillus licheniformis XNRB-3 was isolated from the root tissue of healthy apple trees, and its control effect on apple replant disease (ARD) and its how to alleviates the pathogen pressure via changes in soil microbiomes were studied.Results: The addition of strain XNRB-3 in Fusarium infested soils significantly reduced the number of pathogens in the soil, thus resulting in a lower disease incidence, and the relative control effect reached more than 60%. The fermentation broth can also protect the roots of the plants from Fusarium infection. These antagonistic effects were further validated using an in vitro assay in which the pathogen control was related to growth and spore germination inhibition via directly secreted antimicrobial substances and and indirect interspecific competition for nutrients. The antifungal organic compounds in the fermentation metabolites were identified using GC-MS technology. Among them, alpha-bisabolol and 2,4-di-tert-butylphenol had significant inhibitory effects on many planted pathogenic fungi. Butanedioic acid, monomethyl ester, and dibutyl phthalate can promote the root elongation and lateral root development of Arabidopsis plants. The potential of strain XNRB-3 to control ARD was later validated using microbial fertilizer inoculation in pot and field experiment. The addition of strain XNRB-3 significantly promoted the growth of plants, and the activity of enzymes related to disease resistance (SOD, POD, and CAT) was also significantly enhanced. It also reduced the abundance of Fusarium and the content of phenolic acids in the rhizosphere soil, improved soil microbial community structure and nutritional conditions, and increased soil microbial diversity and activity, as well as soil enzyme activity. Conclusions: The incorporation of strain XNRB-3 in the soil alleviated the damage of soil-borne pathogens to plants by reducing the relative abundance of pathogenic fungi and the content of phenolic acids, and inducing disease resistance of plants. Taken together, B. licheniformis XNRB-3 could be developed into a promising biocontrol and plant-growth-promoting agent. This provides a new management strategy to control ARD.

“…into mineralized nitrogen. Further, soil C conversion status, soil respiration intensity, soil bacterial abundance were positively affected by PGPR applied in the arti cial soil in China (Fu et al 2018), which is in line with our nding that soil sucrase activity was increased upon bacterial fertilizer treatment. Soil urease activity has been reported to potentially re ect soil organic nitrogen supply and soil nutrient transformation (Han et al 2017).…”

Sludge and plant growth-promoting rhizobacteria (PGPR) are widely used to improve soil quality and plant growth. In this study we aim to determine the responses of soil enzyme activities, soil nutrient contents and plant growth to fertilization with sludge and PGPR (Bacillus megaterium strain DU07). To achieve this goal, we planted bare-root eucalyptus seedlings with soil amended with (1) filtered sludge from sugar factory (FS), (2) filtered sludge + PGPR (BF) and (3) non-amended soil (control). Soil properties (soil nutrients and soil extracellular enzymatic activities) and eucalyptus growth (diameter, height and stem volume) were studied 3, 6, 9 and 12 months after treatments. Results indicated that BF significantly increased plant height, diameter, and stem volume after the sixth month. Principal component analysis (PCA) showed that soil quality was significantly increased by BF during our trial period, especially after the ninth month. The pooled regression model indicated that soil quality significantly and positively affected eucalyptus yield, whereas soil TN was negatively and significantly related to plant stem volume. Hence, our study indicates that the application of a bacterial fertilizer increases plant growth and yield via increasing soil quality. Thus, our findings suggest that PGPR amendments could be useful as bio-fertilizer to improve soil-plant interactions in eucalyptus plantations.

“…Such disturbance is increased by additive effects in high altitude areas with a long sunshine duration, an extremely low temperature, constantly changing weather conditions, and concentrated rainfall. The ecosystem in these areas is very fragile and difficult to recover once damaged [7]. Rocky slopes simply do not have the soil environment necessary for the growth of most plant species, nor do they have the proper moisture and sufficient nutrients to meet the needs of the plant growth of most plant species [8].…”

Vegetation restoration on slopes is generally difficult, especially in high altitude areas since the environment has dramatically changing weather conditions that are not suitable for plant growth. In this study, the potential of film mulching for vegetation restoration in such environments and plant growth and nutrients in artificial soil on slopes in high altitude areas were determined. Experiments were carried out in Jiuzhaigou County, Sichuan Province, to determine plant growth and nutrients in artificial soil on slopes under six different coverage rates (40%, 50%, 60%, 70%, 80% and 90%). Results showed that in each observation period, plant height, ground diameter and contents of EN, EP and EK in the soil of the film mulching treatment were significantly higher than those of the control, while the number of plant individuals per unit area was significantly lower than that of the control. When the coverage rate was 90%, plant height, ground diameter, biomass and nutrient contents in the soil were all higher than those under the other five treatments. Overall, our study suggested that applying film mulching technology when performing vegetation restoration on slopes in high altitude areas is promising, since it can promote plant growth and preserve soil fertility.
