Abstract Aims Melon Fusarium wilt, caused by Fusarium. oxysporum f. sp. melonis, is a severe soil-borne disease that reduces melon yield. Biological control approaches have been shown to be effective for the of wilt and could contribute sustainable development industry. Bacillus megaterium (BM) biocontrol strain has promote plant growth diseases. However, few studies examined mechanism which BM controls disease. Methods In this study, we investigated effect on plants, as well soil microbial communities, co-occurrence network, keystone taxa. Results Using pot experiment, showed incidence decreased from 68.33% (CK, inoculated with sterile water) 26.67% (inoculated BM), efficiency was 60.00%. field reduced 5.56% (naturally occurring) 1.67% after treatment, 69.44%. treatment also promoted plants increased yield 20.35%. The abundance potentially beneficial microbes (e.g., Flavobacterium, Nocardioides, Streptomyces, Chaetomium) pathogenic Alternaria, Aspergillus, Mortierella, Plectosphaerella) higher lower in than CK, respectively. Co-occurrence network complexity taxa OTU2869 (Pseudomonas), OTU3763 (Sphingobacterium), OTU2440 (Streptomyces) play key roles CK. Conclusions results our study indicated an agent increase altered composition taxa, indicating it alter community, decrease wilt.

Adopting an optimal cropping regime is crucial for sustainable soil use. However, how different regimes impact phosphorus (P) availability and the underlying mechanism remain unclear. Here, a 10-year field experiment was performed to examine influence of regimes, including maize–soybean rotation (MSR), continuous maize (CMC), farmland fallow (FALL), under unfertilized fertilized conditions in Northeast China. The P forms were analyzed using chemical fractionation solution phosphorus-31 nuclear magnetic resonance. Compared FALL, total contents significantly lower MSR CMC systems. Moreover, higher than those CMC. Correlation analysis showed that there significant positive correlations between contents. Redundancy revealed organic carbon (SOC) as most factor influencing P. Structural equation modeling demonstrated direct impacts SOC, nitrogen, phosphorus, Olsen on phosphatase activity, which exhibited availability. In summary, effective promoting accumulation this region.

Introduction Potato is an important crop that can be used both as grain and vegetable in northern China. However, the continuous cropping system of potato has led to a sharp decline its yield quality. As one effective strategies alleviate obstacle, rotation received extensive attention agricultural practices. On this basis, we have conducted in-depth exploration effects potato-maize on structure diversity soil microbial community, aiming analyze internal correlation mechanism between community quality crops. Methods This study was based fields had been under monoculture for five years established six experimental treatments: potato-potato-potato (IR-A), potato-maize-potato (IR-B), potato-maize-maize (IR-C), (RF-A), (RF-B), (RF-C). Results The results showed IR planting model, IR-B significantly increased vitamin C content while reducing sugar compared IR-A ( p < 0.05).

The limitations and weaknesses of continuous melon cropping have worsened in recent years. A melon–broccoli rotation can possibly alleviate the problems associated with monoculture; however, underlying mechanisms their impact on rhizosphere’s soil microbial community remain unclear. Thus, high-throughput sequencing was used to evaluate rhizosphere soil’s community’s relative abundance diversity under monoculture systems. We found that fungal bacterial richness increased while fungi abundances, such as Fusarium spp. were significantly decreased broccoli rotation. During cropping, enriched Acidobacteria Streptomyces spp., Sphingomonas Pseudomonas identified, which play important roles alleviating obstacles. rendered acidic, underwent secondary salinization, rapidly accumulated organic carbon nitrogen, lost abundant phosphorus potassium. In contrast, partially mitigated these negative physicochemical responses. Redundancy analysis revealed pH, soluble salt content, linked structures community. Melon–broccoli could effectively equilibrate microenvironment overcome challenges deficiencies cropping.
