Biological Control of Melon Continuous Cropping Obstacles: Weakening the Negative Effects of the Vicious Cycle in Continuous Cropping Soil.

The continuous cropping obstacles of melons have become increasingly serious in recent years. To investigate this, we explored the effects and mechanisms of Bacillus subtilis C3 in control of the continuous cropping obstacles of melon. We provide a novel interaction model of the occurrence factors of continuous cropping obstacles.

Spatial Patterns and Composition Traits of Soil Microbial Nitrogen-Metabolism Genes in the Forests at a Regional Scale.

Microbial-driven processes related to the nitrogen-metabolism (N-metabolism) in soil are critical for ecosystem functioning and stability. There are spatial patterns of microbial-mediated nitrogen processes, but we still lack an overview of the soil N-metabolism genes of single nitrogen-fixing tree species pure forests at a regional scale. Here, we investigated the spatial variation and drivers of microbial N-metabolism genes in the rhizosphere soil of on the Loess Plateau by metagenomic technology.

Biocontrol Mechanism of C3 Against Bulb Rot Disease in P.Y.Li.

Bulb rot disease has become one of the main diseases that seriously affects the yield and quality of P.Y.Li ().

[Community characteristics and functions of phosphate-solubilizing bacteria in rhizosphere soil of natural and planted forests on the Loess Plateau, Northwest China].

To investigate the interaction between and root microorganisms and its effects on the stability of forests, we collected rhizosphere and non-rhizosphere soil from natural and planted forests in Huanglong County of Shaanxi Province. The non-rhizosphere soil was used to analyze chemical properties, while the rhizosphere soil was used to isolate and purify phosphorus-solubilizing (organic and inorganic phosphorus) bacteria. We mea-sured the phosphate-solubilizing ability and identified those bacteria using DNA genes sequencing.

Root colonization and growth promotion of soybean, wheat and Chinese cabbage by Bacillus cereus YL6.

Although phosphate-solubilizing bacteria (PSBs) are used in agricultural production, comprehensive research on PSB that colonize the rhizosphere of different plants and promote plant growth is lacking. This study was conducted to examine the growth-promoting effects and colonizing capacity of strain YL6, a PSB. YL6 not only increased the biomass of soybean and wheat in pot experiments but also increased the yield and growth of Chinese cabbage under field conditions.
