High concentrations of salt ions in salinized soils not only destroy soil structure, but also inhibit crop growth. Straw and straw-derived biochar have great potential improving reducing salinity, environment, alleviating stress. However, the effects mechanisms exogenous addition different carbon sources on aggregate structure microbial community with salinization degrees cotton fields as well antioxidant defense system are still unclear. In this column experiment since 15 March, 2023, three contents (1.5 (S1), 5 (S2), 10 (S3) g/kg) five treatments (straw incorporation: 6 t/hm 2 (C1), 12 (C2); 2.25 (B1), 4.5 (B2); CK: no straw incorporation) were designed. Then, incorporation particle size distribution aggregates, bacterial fungal communities, leaf S1, S2, S3 explored. The results showed that incorporation, especially B2, significantly reduced content soils, increased proportion macroaggregates by 7.01%–13.12%, 5.03%–10.24%, 4.16%–8.31%, respectively, compared those CK. C2, abundances Actinobacteria, Acidobacteria, Enterobacteriaceae, decreased Proteobacteria, Besides, superoxide dismutase (SOD) catalase (CAT) activities salt-stressed leaves, malondialdehyde (MDA) peroxidase (POD) activity, It should be noted effect stress gradually growth increase salinity. summary, could reduce diversity, alleviate cotton. This study will provide a scientific basis for improvement utilization soils.

Soil bacterial diversity and community structure of cotton rhizosphere under mulched drip- irrigation in arid and semi-arid regions of Northwest China

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Фев. 3, 2025

Background Xinjiang is situated in an arid and semi-arid region, where abundant heat sunlight create highly favorable conditions for cotton cultivation. Xinjiang's output accounts nearly one-quarter of global production. Moreover, the implementation advanced planting techniques, such as 'dwarfing, high-density, early-maturing' strategies combined with mulched drip irrigation, ensures stable high yields this region. Despite these advancements, limited research has focused on microbial mechanisms fields employing methods. Results The bacterial phoD communities rhizosphere were predominantly composed nine phyla (i.e., Proteobacteria, Actinobacteria, Acidobacteria, Gemmatimonadetes, Chloroflexi, Bacteroidetes, Rokubacteria, Firmicutes, Nitrospirae) five Planctomycetes, Firmicutes), respectively. Alpha diversity analysis indicated that medium yield field (MYF) exhibited higher richness indices compared to low (LYF) (HYF) fields. symbiotic network LYF revealed greater values average degree, number edges, modularity, suggesting a more complex structure both communities. Mantel test, RDA, PLS-PM model identified soil pH, electrical conductivity (EC), organic phosphorus (OP), available (AP), total nitrogen (TN), biomass carbon (MBC), clay content main driving factors influencing changes community structure. Conclusion These findings provide theoretical basis future aimed at improving quality yield.

Intercropping has the function of promoting plant growth, improving yield and quality. Platycodon grandiflorus (P. grandiflorus) is a traditional Chinese medicinal herb; continuous cropping obstacles significantly inhibit its However, few study have established about P. interaction various crops. This provides theoretical foundation to explore most effective intercropping method, enhance soil utilization efficiency, increase quality grandiflorus. We conducted field experiment, monoculture (JG-JG), Achyranthes bidentata (JG-NX), Saposhnikovia divaricata (JG-FF), Glehnia littoralis (JG-SS) intercropping. Additionally, we included three main crops with grandiflorus, Zea mays (JG-YM), Setaria italica (JG-GZ), Glycine max (JG-DD). The physicochemical properties, enzyme activity, microorganisms, secondary metabolite content in roots were determined. results showed that increased reduced incidence rate root rot. system enhances physical chemical properties soil, microbial diversity. JG-SS abundance bacteria fungi, stimulated communities, promoted platycodin D, enhanced complexity co-occurrence networks. could provide sustainable planting for cultivation particularly JG-SS.

Soil salinization is one of the major environmental problems facing world at present, and its negative impact on agricultural production ecological balance increasingly prominent. In this study, BP neural network algorithm was applied to build a prediction model plant productivity in salt-affected soils improved by biochar, internal mechanism biochar application affecting growth deeply revealed. The results showed that nitrogen content (SHAP = 0.08) had most significant positive effect vegetation productivity. pH value 0.06) amount certain effect. This study not only provides solid theoretical basis for restoration soils, but also important technical support sustainable management practice has scientific practical significance promoting soils.
