While remote sensing technologies offer multi-scale observational capabilities, conventional crop monitoring models face two critical limitations: (1) the independent retrieval of individual physiological traits, which overlooks the dynamic coupling between structural and physiological traits, and (2) inadequate cross-platform model transferability (e.g., from UAV images to satellite images), hindering the scaling of field-level precision to regional applications. To address these challenges, we proposed a deep learning-based framework, Cross-Task Growth Neural Network (CTGNN). This framework employed a dual-stream architecture to process spectral features for Leaf Area Index (LAI) and Soil Plant Analysis Development (SPAD), while using cross-trait attention mechanisms to capture their interactions. We further assessed the knowledge transfer capabilities of the model by comparing two transfer learning strategies—Transfer Component Analysis (TCA) and Domain-Adversarial Neural Networks (DANN)—in facilitating the adaptation of UAV-derived (1.3 cm/pixel) data to satellite-scale (3 m/pixel) monitoring. Validation using UAV-satellite synergetic datasets from extensively field-tested oat cultivars in China's Bashang Plateau demonstrates that CTGNN significantly reduces the prediction errors for LAI and SPAD compared with independent trait models, with RMSE reductions of 6.4–14.4 % and 10.5–15.6 %, respectively. In a cross-domain transfer learning scenario, the CTGNN model with the DANN strategy requires only 5 % of satellite-labeled data for fine-tuning to achieve regional-scale monitoring (LAI: R2 = 0.769; SPAD: R2 = 0.714).

In this study, a UAV hyperspectral deep learning network (VitiChlNet) for estimating LCC of wine grapes was constructed. The estimation and mapping of LCC of wine grapes of different varieties and growth stages were realized by combining the three-dimensional radiation transfer model (3D RTM) and deep transfer learning (TL) techniques. Firstly, 80,000 canopy reflectance data under different canopy structures and observation conditions were simulated using the LESS model, the simulation dataset was then pre-trained using VitiChlNet. Finally, the model was fine-tuned using the TL technique based on the measured UAV hyperspectral and LCC data. The performance of VitiChlNet was compared to empirically-based and physically-based approaches. Specifically, three machine learning (ML) empirical models, XGBoost, LightGBM, and ridge regression, were developed using five different spectral feature construction strategies: full-spectrum, vegetation indices (VIs), competitive adaptive reweighted sampling (CARS), successive projections algorithm (SPA), and uninformative variable elimination (UVE). Meanwhile, a look-up table (LUT) inversion strategy based on the LESS model was constructed. Furthermore, LCC mapping was conducted for various wine grape varieties across different growth stages.

However, existing methods still fall short in generating localized soil property maps in real time, limiting inter-row seeding control for wide-span planters. To address this challenge, this paper proposes the Local Soil property distribution maps Generation Network (LSGN), based on the Wasserstein Generative Adversarial Network with Gradient Penalty and Mean squared error (WGAN-GPM). This proposed model integrates a Vision Transformer (ViT) encoder with convolutional and deconvolutional Residual Networks (ResNet), significantly improving feature extraction from discrete soil property data and enhancing the reconstruction accuracy of localized soil maps. The model adopts a two-stage training strategy. First, it performs self-supervised pre-training using local soil property maps with neighborhood information, enabling the network to learn spatial correlations and improve boundary prediction. Second, the pretrained weights are transferred into a WGAN-GPM adversarial training framework, which combines Wasserstein distance, gradient penalty, and Mean Squared Error (MSE) loss to jointly optimize the generator and discriminator. This ensures both pixel-level accuracy and distributional consistency. Compared to standard Generative Adversarial Networks (GANs), the WGAN-GPM-trained LSGN prediction reduces Relative Error Average (REA) by over 1.02 %, RMSE by over 0.16, and Kullback–Leibler Divergence (KLD) by over 1.76 × 10<sup>−4</sup>, while increasing Peak Signal-to-Noise Ratio (PSNR) by over 2.43.
