Leaf area index (LAI) serves as a crucial indicator for characterizing the growth and development process of maize. However, LAI inversion maize based on unmanned aerial vehicles (UAVs) is highly susceptible to various factors such weather conditions, light intensity, sensor performance. In contrast satellites, spectral stability UAV-based data relatively inferior, phenomenon “spectral fragmentation” prone occur during large-scale monitoring. This study was designed solve problem that UAVs difficult achieve both high spatial resolution consistency. A two-stage remote sensing fusion method integrating coarse fine proposed. The SHapley Additive exPlanations (SHAP) model introduced investigate contributions 20 features in 7 categories maize, canopy temperature extracted from thermal infrared images one them. Additionally, most suitable feature sampling window determined through multi-scale experiments. grid search used optimize hyperparameters models Gradient Boosting, XGBoost, Random Forest, their accuracy compared. results showed that, by utilizing 3 × 9 with highest contributions, whole stage Forest could reach R2 = 0.90 RMSE 0.38 m2/m2.

Timely sowing is a crucial cultivation practice for enhancing crop productivity. In Shandong Province, inadequate supporting techniques are the primary factors limiting yield and quality improvement of high-quality strong-gluten wheat (Triticum aestivum L.). A promising strategy achieving synergistic improvements in both involves matching date density to specific ecological conditions each region. To explore this approach, we conducted continuous field experiments at three testing stations—Jining, Dezhou, Yantai—across major wheat-growing regions Province from 2019 2021. Four dates (T1: October 5; T2: 15; T3: 25; T4: November 5) seven planting densities (ranging 135 × 104 plants ha−1 405 ha−1, denoted as D1–D7) were tested location. The results revealed that zone initially increased, then decreased delayed. Jining high grain yields typically observed all under T3, while Yantai showed optimal T2. Specifically, achieved highest 9326.6 kg with 315 on 25 (T3D5), Dezhou reached their maximum 225 15 (T2D3), 8784.0 9366.3 respectively. Except compliance rate sites followed an increasing trend initially, which declined later dates. Yantai, rates most frequently T2, T1. conclusion, selecting appropriate can lead across Shandong’s regions.
