After continuous cropping for many years, crops are often subject to growth inhibition, which seriously affects their yields.In agricultural production, soil fumigation can effectively alleviate the biological stress on plants. However, relationship between microbial groups that respond changes and plants, as well whether existence makes a beneficial contribution remains unclear. We explored mechanism of promoting plant by affecting microorganisms. The results showed dazomet treatment significantly alleviated retardation tobacco, this difference was most obvious in flourishing period when height leaf area increased 3.33 times 3.24 respectively. In addition, advantage above-ground tissue correlated with root (P < 0.05). At same time, we found large number positively related roots, such g_Pedobacter, g_Microbacterium g_Brevundimonas. structural equation modeling indicated community, amount applied also roots 0.05), an important factor contributing tobacco. Overall, findings study great significance enhancing our understanding remediation may have far reaching implications practical application fumigation.

Continuous cropping obstacles pose significant constraints and urgent challenges in the production of Tussilago farfara L. This experiment investigated effects consecutive on T. over periods 1, 2, 3 years. It assessed yield quality flower buds, addition to physicochemical properties rhizosphere soil. The microbial community was analyzed through 16S rDNA ITS sequencing using Illumina Novaseq high-throughput technology, while also examining correlations among these factors. results reveal that as duration continuous increases, along with contents extract, tussilagone, total flavonoids, steadily decreased; soil pH, organic matter, available phosphorus, potassium, alkaline nitrogen, activities sucrose, catalase, phosphatase markedly decreased. As quantity diversity bacteria initially increase then decrease, number fungal species increases by 22.5%. Meanwhile, contributes a gradual reduction relative abundance beneficial genera such Ralstonia, Nitrospira, Trichoderma soil, harmful Mortierella, Fusarium, Tricharina accumulate significantly. Correlation analysis shows changes communities notably influence growth quality. study elucidates impacts properties, rhizosphere, providing scientific basis for further research barriers selection farfara.

Continuous cropping of the same crop leads to land degradation. This is also called continuous-cropping obstacle. Currently, intercropping tobacco with other crops can serve as an effective strategy alleviate continuous obstacles. In this study, K326 and insectary floral plants were used materials, seven treatments monoculture (CK), intercropped Tagetes erecta, Vicia villosa, Fagopyrum esculentum, Lobularia maritima, Trifolium repens, Argyranthemum frutescens respectively, set up study their effects on rhizosphere soil chemical properties composition structure microbial community tobacco. The 16 S rRNA gene ITS amplicons sequenced using Illumina high-throughput sequencing. tobacco/insectary influence properties, which change communities. CK treatment groups microorganisms had significantly different genera, such T. repens A. increased number Fusarium V. L. Sphingomonas unknown Gemmatimonadaceae. Additionally, villosa maritima changed fungal bacteria positive correlation between genera fungi bacterial greater than CK. pathway carbohydrate metabolism, amino acid energy metabolism in decreased after cropping. Fungal symbiotic trophic saprophytic plant pathogen animal frutescens. communities correlated respectively. reveals that plants, particularly affects alters communities, increasing abundance certain genera. enhances pathways related carbohydrate, acid, bacteria. These findings suggest could provide a promising overcome challenges associated by regulating environment.

Alfalfa with Forage Crop Rotation Alleviates Continuous Alfalfa Obstacles through Regulating Soil Enzymes and Bacterial Community Structures

Agronomy, Год журнала: 2024, Номер 14(7), С. 1349 - 1349

Опубликована: Июнь 21, 2024

Alfalfa is a perennial herbaceous forage legume that significantly and adversely affected by monocropping. Crop rotation the most effective measure to overcome continuous cropping obstacles. However, mechanisms of how bacterial communities are potential links between these effects systems remain poorly understood. Based on long-term field experiments with alfalfa crops in black soil region western Songnen Plain Northeast China, alterations community structure using high-throughput sequencing 16S rRNA gene chemical properties enzyme activities were analyzed. The alfalfa–forage oats–silage maize–alfalfa alfalfa–silage maize–forage oats–alfalfa system increase levels total phosphorus available phosphorus, promote acid phosphatase, β-glucosidase, leucine aminopeptidase, N-acetyl-β-glucosaminidase comparison alfalfa. While crop did not affect α-diversity bacteria, it altered composition structure. Some key taxa enriched soils, including Bacillus, Sphingobium, Paenibacillus, Hydrogenispora, Rubrobacter, Haliangium, Rubellimicrobium. Additionally, increased stability complexity co-occurrence network. our findings, we recommend promoting as ideal practices for overcoming challenges associated These only enhance nutrient content but also foster beneficial microbial community, ultimately improving functionality performance.

Studies have shown that plant endophytic microbial communities are ubiquitous and closely related to growth health. To clarify the mechanism of melon varieties with high resistant wilt, compositions metabolites in roots ability wilt were analyzed. The results showed abundances Firmicutes, Ascomycota, Bacillus, Bradyrhizobium, Amycolatopsis, Actinospica, Catenulispora all increased (MT) which compared susceptible (MS). Meanwhile, Ochrobactrum, Bordetella, Roseateles, Staphylococcus, Acidovorax, Catenulispora, Promicromonospora, Gymnopilus unique microbes MT. Moreover, comparison MS varieties, functions Defense mechanisms, Secondary biosynthesis, transport catabolism, Nucleotide metabolism, Signal transduction Coenzyme Carbohydrate metabolism Amino acid MT varieties. Additionally, nucleotide biosynthesis cofactors metabolic pathways also significantly On other hand, untargeted metabolome Biosynthesis various secondary metabolites, expression varieties; content compounds such as flavonoids, Cinnamic compounds, Organic Nucleotides increased. In addition, correlation between microbiome indicates a significant two. All above suggested higher abundant antagonistic endophytes important mechanisms for their resistance wilt.

In recent years, a significant impediment to the advancement of China’s agricultural sector is noteworthy challenge posed by diminished crop yields and quality due ongoing continuous cropping obstacles. Numerous studies have consistently showcased potential plant growth-promoting rhizobacteria (PGPR) biochar in augmenting alleviation barriers. Nevertheless, PGPR remediate improve peppers karst yellow soil area remains unclear. A 2-year field experiment was implemented examine impact biochar, when applied alone or combination, on production peppers. The results revealed that significantly elevated yield fresh dry pepper compared with TF treatment. utilization resulted an augmentation free amino acids, soluble sugar, vitamin C content fruits, but reduction nitrate content, which proved advantageous enhancing overall Furthermore, use demonstrated benefits NPK accumulation, fertilizer utilization, economic efficiency. co-application yielded better their individual application. conclusion, favorable productivity simultaneous application represents promising approach improving region Southwest China.
