Casuarina equisetifolia (C. equisetifolia) is an economically important forest tree species, often cultivated in continuous monoculture as a coastal protection forest. Continuous planting has gradually affected growth and severely restricted the sustainable development of C. industry. In this study, we analyzed effects on explored rhizosphere soil microecological mechanism from metagenomic perspective. The results showed that resulted dwarfing, shorter root length, reduced seedling system. Metagenomics analysis 10 key characteristic microorganisms, mainly Actinoallomurus, Actinomadura, Mycobacterium, were responsible for continuously planted trees. Quantitative number microorganisms these three genera decreased significantly with increase planting. Gene function led to weakening environmental information processing-signal transduction ability decrease trees against stress. Reduced capacity metabolism, genetic processing-replication repair microbial propagation quantity Secondly, amino acid carbohydrate glycan biosynthesis lipid metabolism cofactors vitamins all reduced, resulting synthesize metabolize carbon nitrogen. These capacities further quantity, nitrogen, respiration intensity, enzyme nutrient cycling resistance-related activities, significant reduction available content soils, ion exchange capacity, impediment growth. This study provides basis management plantations.

Abstract Bacteria and fungi are core microorganisms in diverse ecosystems, their cross‐kingdom interactions considered key determinants of microbiome structure ecosystem functioning. However, how bacterial‐fungal mediate soil organic carbon (SOC) dynamics remains largely unexplored the context artificial forest ecosystems. Here, we characterised bacterial fungal communities four successive planting Eucalyptus compared them to a neighbouring evergreen broadleaf forest. Carbon (C) mineralisation combined with five C‐degrading enzymatic activities was investigated determine effects on SOC dynamics. Our results indicated that significantly altered diversity increased negative associations. The decreased all plantations forest, while showed opposite trend. ratio associations due decrease SOC, ammonia nitrogen (NH 4 + ‐N), nitrate (NO 3 − ‐N) available phosphorus (AP). Structural equation modelling potential competition, based correlations, negatively associated total bacteria keystone bacteria, thereby increasing C mineralisation. Synthesis applications : highlight regulatory role association enhancing correlation between This suggests promoting short‐term management can mitigate impact this decomposition. Taken together, our study advances understanding plantations, giving us new insight into cycling forests.

Near-natural forest management plays an important role in the maintenance of long-term productivity and soil fertility plantations. We conducted high-throughput absolute quantitative sequencing 16S rRNA genes to compare structures diversity rhizosphere bacterial communities among a pure Chinese fir (Cunninghamia lanceolata) plantation (S), Cunninghamia lanceolata-Castanopsis hystrix-Michelia hedyosperma mixed (SHX), fissa (SD). The results revealed that near-natural improved properties fir, especially phosphorus content. Rhizosphere SHX SD contained higher total abundances more unique operational taxonomic units (OTUs) than forest. Planctomycetes Actinobacteria were abundant SD, enriched SHX. tree species also had impact on communities. For soils different SHX, available (AP) content significantly surpassed those Castanopsis hystrix Michelia hedyosperma. Bacteria related nitrogen fixing, such as Burkholderiales Rhizobiales, fissa.

Continuous planting is unavoidable in agricultural production, but continuous affects plant growth and physiological characteristics. In this study, we analyzed rhizosphere soil nutrients, characteristics, hormone metabolome changes their interactions of Casuarina equisetifolia (C. equisetifolia) with the increase number. The results found that C. root was significantly inhibited, height dwarfed biomass reduced as number increased. Secondly, caused a decrease nutrient transformation capacity, significant total available content. Analysis indexes showed resulted nitrogen, phosphorus, potassium content, activity resistance, photosynthetic capacity leaves. Hormone analysis critically affected accumulation five characteristic hormones leaves, which salicylic acid 2-O-β-glucoside (SAG), 2-oxindole-3-acetic (OxIAA), trans-zeatin-O-glucoside (tZOG) gibberellin A3 (GA3) content decreased while abscisic (ABA) increased significantly. conclusion, lowered equisetifolia, inhibited growth, hindered uptake transportation by root, thus led to leaves SAG, OxIAA, tZOG, GA3 synthesis ability decreased, ABA accumulated large quantities, resistance photosynthesis impeded. This study provides insights for effective management cultivation equisetifolia.

Soil microbes are critical in regulating the growth and function of eucalyptus plantations. The mechanisms underlying soil microbial communities’ response to different plantation management practices remain elusive. In this study, we compiled datasets containing 2744 observations across global eucalyptus-planted regions analyzed effects five (i.e., burning, residual removal, fertilization, mixed planting, controlling planting years) on biomass, diversity, structures. Our results showed that fungal community alpha diversity responds more sensitively than bacterial Although implementation significantly increased content most nutrients biomass elements (excluding burning), these did not necessarily improve particularly among communities. Burning, mixing with nitrogen-fixing species decreased communities, which were mainly impacted by organic carbon total potassium content. Compared four other practices, favored communities storage nitrogen, making it effective practice. However, attention should also be paid protection addition, changed structures, positively correlated nitrogen and, a lesser extent, diversity. highlight importance prioritizing as practice safeguarding during its suggest development associated contents given priority management.
