This study aimed to investigate the impacts of straw and biochar on greenhouse gas (GHG) emissions grain yield in a double rice cropping system under optimal N fertilizer reduction. Conventional fertilization (CF) was used as control group, treatments included 15% less nitrogen (OF), together with (S) or (B) applied different conditions, namely CF + S, B, OF B. The effects soil CH4 N2O were studied, changes physicochemical properties analyzed. results showed that relative CF, S increased...

Accurate, rapid, and intelligent stored-grain insect detection counting are important for integrated pest management (IPM). Existing models often not suitable detecting tiny insects on the surface of grain bulks require high computing resources computational memory. Therefore, this study presents a YOLO-SGInsects model based YOLOv8s bulk by adding object layer (TODL), adjusting neck network with an asymptotic feature pyramid (AFPN), incorporating hybrid attention transformer (HAT) module...

The frequent occurrence of urban floods (UFs) poses significant threats to public safety and the national economy. Accurate estimation flood susceptibility (UFS) identification potential hotspots are critical for effective UF management. However, existing UFS studies often fall short due a limited understanding UFs’ nature, frequently relying on disaster factors analogous those used natural while neglecting key characteristics, limiting accuracy estimates. To address these challenges, we...

Abstract. Understanding leaf stoichiometric patterns is crucial for improving predictions of plant responses to environmental changes. Leaf stoichiometry terrestrial ecosystems has been widely investigated along latitudinal and longitudinal gradients. However, very little known about the vertical distribution C : N P relative effects parameters, especially shrubs. Here, we analyzed shrub C, in 125 mountainous sites over an extensive altitudinal gradient (523–4685 m) on Tibetan Plateau....

Legume alfalfa (Medicago sativa L.) is extensively planted to reduce chemical fertilizer input the soil and remedy damaged fields. The mechanism of these effects potentially related variations in alfalfa-mediated interactions microbial community. To understand impact planting on community degraded black cultivated land, a 4-year experiment was conducted land. We assessed parameters characterized functional compositional diversity by amplicon sequencing that targeted 16S rDNA gene bacteria...

Abstract Ectomycorrhiza (ECM) plays an important role in plant nitrogen (N) nutrition and regulates responded to climate warming. We conducted a field experiment natural forest plantation the eastern Tibetan Plateau estimate warming effects of open-top chambers (OTC) on ECM N Picea asperata seedlings. Four-year significantly decreased colonization, fungal biomass, fine root vigor concentration leaf, stem coarse root, but increased content stem, whole forest. Contrarily, induced no obvious...
