An L1 Adaptive Control Method with an Extended State Observer for Fixed-Wing UAV Attitude Control

To address issues such as nonlinear strong coupling, time-varying parameters, and external wind disturbances in fixed-wing unmanned aerial vehicles (UAVs) operating in complex flight environments, this study develops a composite attitude control method integrating L1 adaptive con...

Physiological and multi-omics analyses reveal BCAA-related responses and photosynthetic preservation associated with differential nicosulfuron tolerance in sweet maize

Nicosulfuron, an acetolactate synthase (ALS)-inhibiting herbicide widely used for post-emergence weed control in maize, can cause severe genotype-dependent phytotoxicity in sweet maize. At 80 mg L −1 nicosulfuron, the sensitive genotype HK320 showed 100% mortality, whereas the to...

Digital Financial Inclusion and Agricultural New Quality Productive Forces: Evidence from China

Agricultural new quality productive forces (ANQP) provide an important foundation for high-quality agricultural development and sustainable rural transformation. Using panel data for 30 Chinese provinces from 2011 to 2022, this study examines the effect of digital financial inclu...

Effects of Different Fruit Set Enhancement Treatments on Fruit Set Rate and Fruit Quality of the Self-Compatible Sweet Cherry Cultivar ‘Sunburst’ Under Protected Cultivation

Sweet cherries are an important temperate fruit crop, and protected cultivation has expanded rapidly in recent years. However, unstable fruit set under protected cultivation remains a major challenge, and the application of fruit set enhancement treatments has become common pract...

Topography-Mediated Nonlinear Responses of Soil Organic Carbon Stocks to Multi-Gradient Warming and Precipitation Shifts in Northeast China’s Temperate Mountain Forests

Soil organic carbon (SOC) in mountain forest ecosystems exerts critical controls over regional carbon balance and climate feedback loops. This study collected 209 stratified topsoil (0–30 cm) samples across temperate mountain forests of Northeast China, conducted a boosted regres...

Heterogeneity and Controlling Mechanisms of Soil Organic Carbon Stocks Across Erosion Zones in China Under Future Climate Scenarios

ABSTRACT Soil organic carbon (SOC), as a key indicator of global carbon cycling and climate change response, plays a critical role in regional ecological security and agricultural sustainability. This study employs three machine learning models including the LightGBM, XGBoost, an...

Microbial Community Structure Diversity of Male and Female Poplar Plants of the Same Faction and Its Influencing Factors

Phyllosphere microorganisms interact with host plants to regulate growth, promote nutrient uptake and enhance stress tolerance with host specificity, while arbuscular mycorrhizal fungi facilitate plant nutrient absorption and stress adaptation. Current poplar microbial studies mo...

Microbial Community Remodeling Mediates Soil Nutrient Enhancement and Fruit Quality Improvement Under Intercropping with Vicia sativa L.

This study investigated whether legume cover crops, particularly Vicia sativa L., improve soil fertility and fruit quality via microbial community remodeling, and whether this practice outperforms natural grass management in pear orchards. Five treatments were established: clean...

Molecular detection of watermelon virus disease in Liaoning Province, China, and resistance evaluation of nine rootstocks to cucumber green mottle mosaic virus

Watermelon diseases have become increasingly severe in Liaoning Province, which is a major watermelon-growing region in China. To investigate the occurrence of watermelon virus diseases and identify the predominant virus types, 330 symptomatic samples from three major producing a...

A Stepwise Correction Model for Operational Forecasting of Surface Soil Moisture During the Spring Sowing Period

Accurately predicting soil moisture conditions and determining the optimal sowing timing during the spring sowing period play a crucial role in ensuring high and stable grain yields. To address the limitations of existing soil moisture prediction models, i.e., the complexity and...
