Crop rotation aims to improve the sustainability and production efficiency of agricultural ecosystems, especially as demands for food energy continue increase. However, regulation soil microbial communities using crop with oilseed flax its relationship key physicochemical driving factors are still not clear. In order investigate this matter, we carried out a field study lasting four years involving various sequences including FWPF, FPFW, PFWF, FWFP, ContF, ContF1. addition evaluating parameters, employed Illumina high-throughput sequencing technology explore structure variety communities. The findings indicated notable rise in pH value FPFW treatment contrast other treatments, along significant increases AP, MBC, MBN, qSMBC compared ContF. number OTUs WFPF, PFWF treatments was significantly increased by 4.10–11.11% ContF (p < 0.05). presence Actinobacteria Acidobacteria greatly impacted treatment, whereas Chloroflexi notably influenced treatment. bacterial community primarily TC, pH, NO3−-N according correlation analysis. Specifically, therapy raised level while lowering TC level. Furthermore, led proportion decline Actinobacteria. These provide important theoretical support regulate solve problems continuous cropping.

Aiming at the problems of serious soil desertification, increased and water loss, reduced soil-available nutrients in agro-pastoral ecotone Northeast Inner Mongolia, this study took corn variety A6565 as planting crop analyzed seven different tillage measures, deep tillage, loosening, shallow rotary heavy harrow, no-tillage, control, combined with straw returning an experimental field Arong Banner. The analysis results are follows: urease activity microbial biomass nitrogen content method straw-returning treatment were higher than other treatments. Compared seedling stage, alpha diversity index bacteria harvest while that fungi was opposite. β comparison showed sampling time main factor affecting bacterial community composition. It found dominant Proteobacteria Actinomycetes, fungus Ascomycetes. Conservation has a positive impact on diversity, which is more helpful for improving quality. All findings may contribute to restricting series important factors sustainable agricultural development, such degradation.

The quality of cigar tobacco is influenced by various factors, among which the ecological environment plays a crucial role. However, it remains uncertain whether Yunnan, known for its diverse environment, suitable growth tobacco. Therefore, objective this study was to investigate disparities in soil physicochemical properties and microbial community across three ecoregions namely Longyang, Ruili Tengchong, located southwest China. Furthermore, we aimed analyze correlation these factors with growth. results showed that Longyang exhibited higher values pH (7.78±0.11), available potassium (735.72±198.96), cellulase (1.07±0.23) polyphenol oxidase (0.39±0.001) compared promoting (P<0.05). Additionally, demonstrated greater fungal diversity but lower bacterial Correlation analysis structural equation modeling further confirmed primary factor influencing (r=0.802, P< 0.01). Moreover, bacteria sensitivity fungi, structure significantly plant (P< 0.05). In summary, alkaline enriched organic matter potassium, favorable conditions thereby proved more

Abstract Continuous cultivation of tobacco could cause serious soil health problems, which bacterial to change fungal soil. In order study the diversity and richness community in tobacco-growing under different crop rotation, three treatments were set up this study: CK (tobacco continuous cropping); B (barley-tobacco rotation cropping) R (oilseed rape-tobacco cropping). The results showed that with other crops significantly decreased OTUs, also richness, evenness, coverage communities. Among them, most. analysis composition structure community, it was found proportion plant pathogens Nectriaceae from 19.67% 5.63% B, greatly reduced possibility soil-borne diseases. correlation between environmental factors communities, Filobasidiaceae had a strong TP AP, Erysiphaceae TK AK.
