Abstract ：
To address the critical challenges of low success rates and high seedling damage in automatic transplanters for vegetable substrate block seedlings, this study took cabbage substrate block seedlings as the research object and designed a silica gel wheel-synchronous belt clamping seedling separation device. An experimental platform was constructed to perform a three-factor, three-level orthogonal test, investigating the effects of the wheelbase of the silica gel wheel, the inclination angle of the conveyor belt, and the wheelbase of the silica gel wheel and the synchronous belt on seedling separation success rate and substrate block breakage rate. A quadratic regression model was established to analyze the influence of each factor on the index and to optimize the parameter combination verification test. The results showed that the seedling separation effect was better when the wheelbase of the silica gel wheel was 60.47 mm, the inclination angle of the conveyor belt was 8.67 degrees, and the wheelbase of the silica gel wheel and seedling separation synchronous belt was 39.8 mm. The success rate of seedling separation was 90.21% and the substrate block breakage rate was 6.88% in the field verification test of this parameter combination. When the operating speed is 60 plants/min, there is a higher success rate of seedling separation and a lower substrate block breakage rate. This study explored the conditions for stable seedling separation using the seedling separation device, and provided practical reference for the study of the automatic seedling separation of substrate block seedlings.

Abstract ：
随着计算机技术的发展，三维重建技术作为一个新兴领域，越来越广泛用于人们的日常生活中。植物三维重建作为三维重建领域的一个分支，在农业生产、机器人定位、机器人定位、自然景观再现、研究植物生长状态、植物形态研究、电影游戏等多个领域都得到了应用。以白茶这一植物为例，以改进的运动恢复结构为基础进行三维重建。首先，使用直方图均衡化增加了图像的动态范围，再基于yolov5对白茶进行训练以减少背景对重建的影响，训练识别率达到90%以上，再基于运动恢复结构对白茶进行重建得到点云。由于初始点云具有大量噪声点，手动去除噪声点并基于Possion表面重建得到茶树精确三维模型。最后，通过对比不同帧采样、重建精度配置下的重建效率以及模型精度，得到三维重建的最佳重建策略。优化后的重建策略使得重建速度保持在5min以内，并保持了重建精度，为多视角三维重建技术在植物领域的三维重建提供了理论基础。

Abstract ：
Intelligent detection of tomato seedling transplant quality represents a core technology for advancing agricultural automation. However, in practical applications, existing algorithms still face numerous technical challenges, particularly with prominent issues of false detections and missed detections during recognition. To address these challenges, we developed the ESG-YOLO object detection model and successfully deployed it on edge devices, enabling real-time assessment of tomato seedling transplanting quality. Our methodology integrates three key innovations: First, an EMA (Efficient Multi-scale Attention) module is embedded within the YOLOv8 neck network to suppress interference from redundant information and enhance morphological focus on seedlings. Second, the feature fusion network is reconstructed using a GSConv-based Slim-neck architecture, achieving a lightweight neck structure compatible with edge deployment. Finally, optimization employs the GIoU (Generalized Intersection over Union) loss function to precisely localize seedling position and morphology, thereby reducing false detection and missed detection. The experimental results demonstrate that our ESG-YOLO model achieves a mean average precision mAP of 97.4%, surpassing lightweight models including YOLOv3-tiny, YOLOv5n, YOLOv7-tiny, and YOLOv8n in precision, with improvements of 9.3, 7.2, 5.7, and 2.2%, respectively. Notably, for detecting key yield-impacting categories such as "exposed seedlings" and "missed hills", the average precision (AP) values reach 98.8 and 94.0%, respectively. To validate the model's effectiveness on edge devices, the ESG-YOLO model was deployed on an NVIDIA Jetson TX2 NX platform, achieving a frame rate of 18.0 FPS for efficient detection of tomato seedling transplanting quality. This model provides technical support for transplanting performance assessment, enabling quality control and enhanced vegetable yield, thus actively contributing to smart agriculture initiatives.

Abstract ：
This research investigated the behavior of key nutritional elements specifically, titratable acidity (TA), and vitamin C within the xylem and cortex of carrots during various storage durations and temperatures. A hyperspectral imaging system captured 300 images across 472 wavebands ranging from 400 to 1000 nm. Regions of interest (ROIs) were defined to extract average spectra from these hyperspectral images (HSI). We developed two analytical models: support vector regression (SVR) and Partial Least Squares Discriminant Analysis (PLS-DA), to quantitatively analyze the relationships between pigment levels and spectral data. Uninformative Variable Elimination (UVE) and loading weights (LW) approaches were used to select effective wavelengths (EWs) for modeling. The reduction of vitamin C was found to be considerably influenced by changes in storage temperature and time, with comparable effects observed in the cortex and xylem. However, when compared to the cortex, TA showed a more milder increase in the xylem. This study concludes by highlighting the promise of HSI as an effective and non-destructive method for monitoring the chemical composition of carrot roots while they are being stored at different temperatures and times. These results are consistent with earlier studies on the quantitative evaluation of internal carrot quality and add to the body of existing information.

Abstract ：
Accurate identification of tomato fruit stalks is critical for end-effectors to perform precise cutting operations, which contributes to enhanced harvesting efficiency and reduced reliance on manual labor. However, actual field environments may compromise the accuracy of tomato fruit stalks identification. To address this issue, this study proposes an improved GCD-YOLO model based on YOLOv8n. Specifically, GAM is integrated into the YOLOv8 backbone network, the original Neck is replaced with CCFM, and Dyhead is adopted as the detection head for tomato fruit stalks identification. The results show that the different improvement modules can effectively enhance the feature extraction ability of the model, thus improving the detection accuracy of the GCD-YOLO model for tomato fruit stalks. The GCD-YOLO model achieves a detection precision of 94.4% and an mAP@50 of 91.7% for tomato fruit stalks, significantly outperforming YOLOv8n, SSD, Faster R-CNN, YOLOv5n, RT-DETR, YOLOv9t, YOLOv11n and YOLOv12n. Furthermore, the GCD-YOLO model was deployed on an NVIDIA Jetson Orin Nano for field experiments. Experimental results demonstrate that the GCD-YOLO model delivers outstanding detection performance on edge devices, achieving an inference speed of 26.24FPS in actual field environments. The research findings contribute to the development of smart agriculture and facilitate the implementation of machine vision in tomato harvesting applications.

Abstract ：
The operation of electric rice reaper binders in hilly and mountainous areas currently faces the challenges of poor conveying efficiency and high harvest losses caused by the large dispersion of rice stem posture angles. In this study, we propose a multiparameter collaborative optimization method for improving header structure in an effort to address these challenges. First, key parameters influencing lifting performance and their operational ranges were determined based on a theoretical analysis of the stem-lifting mechanism's kinematic characteristics. A dynamic model simulating the header's lifting process was developed by using the ADAMS multibody dynamics platform. Subsequently, we designed a quadratic regression orthogonal rotation combination experiment with three factors, i.e., the stem-lifting speed ratio coefficient, the cutter installation position, and the header tilt angle, using the stem-lifting angle as the evaluation metric. The variance in the experimental data was analyzed with Design-Expert 13.0, and response surface methodology (RSM) was applied to elucidate the parameter interaction effects. The optimal parameter combination was identified as a speed ratio coefficient of 2.14, a cutter installation position of 258.79 mm, and a header tilt angle of 62.63 degrees, yielding a theoretical stem-lifting angle of 2.36 degrees. Field validation tests demonstrated an actual stem-lifting angle of 2.44 degrees (relative error: 3.39%) and a header loss rate of 0.59%, representing a 49.6% reduction compared with the pre-optimized design. These results confirm that the optimized header satisfies operational requirements for hilly terrain rice harvesting, providing both theoretical guidance and technical advancements for the design of low-loss harvesting machinery.

Abstract ：
Aiming at the problems of low success rate and high seedling injury rate of automatic vegetable transplanting, this study focused on cabbage substrate block seedlings and developed a progressive push-out automatic seedling device controlled by a PLC system. Based on the friction mechanical properties of seedlings-tray during seedling taking, the collision rebound theoretical analysis of substrate block seedling delivery and the finite element simulation analysis of the seedling taking mechanism were carried out to determine the conditions for stable seedling taking and delivery of the device and the working parameters of the key mechanisms. To evaluate individual parameter effects, a test bench was built, and the effective ranges key factors were subsequently determined. Three key experimental factors, the inclination angle of the limit guide plate, the seedling separation channel width, and the seedling separation cylinder pressure, were investigated using an L9(3(4)) orthogonal array design with blockage rate and breakage rate as evaluation metrics. The range and variance analysis methods were employed to determine the relative significance of each factor's influence on the performance indicators. The optimal parameters were determined as: the inclination angle of the limiting guide plate was 3.5 degrees, the width of the seedling separation channel was 50 mm, and the pressure of the seedling separation cylinder was 0.6 MPa. Under these conditions, the seedling taking effect was significantly improved: the blockage rate was 2.46%, the breakage rate was 3.18%, and the seedling taking success rate was 94.36%. The optimal parameter combination was verified by the experiment: the average blockage rate was 3.23%, the average breakage rate was 3.68%, and the average success rate was 93.09%. Compared with the orthogonal experiment, the relative success rate error was 1.27%, indicating that the device has high stability. This study will provide reference for the design of automatic vegetable transplanters.
