The patent discloses a method for quickly establishing a Cabernet Sauvignon grape pericarp callus regeneration system, and belongs to the technical field of cell engineering. The method takes the pericarp of Cabernet Sauvignon grape as an explant, realizes efficient induction and rapid regeneration of callus through three key steps of explant disinfection treatment, primary callus induction culture, callus proliferation and subculture. The method optimizes the culture medium formula, adds specific concentrations of 6-BA, KT, IAA, NAA and 2,4-D in the induction medium, and significantly improves the induction rate and growth rate of callus. Experimental results show that the stable callus regeneration system can be obtained in 40-50 days by using the method, the callus induction rate can reach more than 90%, and the survival rate of regenerated plants is high. The patent has the advantages of simple operation, good repeatability and short cycle, and provides an effective technical means for genetic improvement, gene function research and rapid propagation of wine grapes, and has important theoretical value and application prospect.

The present application relates to the field of pattern recognition and image processing based on multi-modal sensor data fusion, especially to a wine grape vineyard intelligent picking management system based on multi-modal data fusion, comprising a perception device group, a computing platform and an execution unit; the computing platform is built-in with a perception module, a defect mapping module, a curvature inversion module, a manifold segmentation module and a constraint addressing module. The system synchronously collects color images and point cloud data, extracts optical space bias vectors through a defect nesting model and reversely calculates physical surface normals to fill in missing coordinates and reconstruct closed fruit grain three-dimensional geometric curves. The manifold segmentation module extracts a three-dimensional topological skeleton of the fruit stem, the constraint addressing module locates the morphological bifurcation structure and outputs picking point coordinate parameters, guiding the execution unit to complete the cutting work. The present application effectively solves the positioning deviation problem caused by inconsistent multi-modal perception under strong light.

This invention relates to the field of grape cultivation technology and discloses a support frame for grape cultivation that adjusts the upright position and leaf canopy. It includes a first electrical box and several support components, with several steel wire ropes connecting the support components. Each support component has a column and a second electrical box. The column has a branch upright adjustment component and a leaf canopy adjustment component. The invention uses a first drive motor to drive an adjusting screw to rotate. Because the adjusting screw and the double-ended movable part are threadedly engaged, the double-ended movable part slides within a limiting groove, allowing the steel wire ropes fixed to the first steel wire fixing structure to adjust their height steplessly. All heights can be adjusted simultaneously, simplifying the traditional manual adjustment process. It can be adjusted in real time along with the support of the wine grapes, offering high flexibility and contributing to the healthy growth of the grape branches.

This invention discloses an IoT-based early warning method for powdery mildew in wine grapes. The method involves acquiring meteorological data for a future time period; inputting this future meteorological data into a trained mapping model from meteorological data to sensor data to obtain predicted sensor data. This sensor data includes the air temperature and humidity of the environment where the wine grapes are located, the duration of leaf moisture on the grape leaves, and the light intensity received by the grapes. Based on an index scoring function for each type of sensor data, an index score is calculated and weighted to obtain a comprehensive risk score. A dynamic early warning threshold is set, and the percentage of the comprehensive risk score relative to the dynamic early warning threshold is calculated. Different early warning signals are triggered based on different percentages. The invention also discloses a corresponding early warning system. This invention achieves accurate early warning of powdery mildew.

For wine grapes, pruning and shaping account for one-third of the total working time, and there are significant differences between peak and off-peak seasons, making it a challenge to secure peak labor. For table grapes (especially large-berry varieties), cluster formation and harvesting account for more than half of the total working time, requiring workers to keep their arms raised, resulting in poor work efficiency and the need to constantly look upwards. This invention provides a grape pruning method that improves work efficiency. [Solution] Multiple support posts are erected in the direction of the furrow, and the tops of each are connected with horizontal downpipes. A V-shaped corrugated roof rain cover is installed so that rainwater flows into it. A rain cover is created by connecting the ground side of the bottom of the corrugated roof to the horizontal downpipes at regular intervals with wires in the direction of the furrow. Seedlings are planted directly below the valleys of the V-shaped roof. The growing shoots are extended in a straight line in the direction of the furrow directly below the horizontal downpipes to become the main branches. When new shoots sprout from both sides, the grapes will try to grow upwards due to their nature and will hit the corrugated roof. However, if they try to grow further they will reach the nearest ridge, and thereafter they will be pruned autonomously along the ridge.
