The application discloses a system and method for determining the prevention and control suitable period of grape Dendroctonus valens based on image recognition, and belongs to the cross technical field of plant protection and computer vision. A plurality of two-dimensional images are continuously acquired by an image acquisition device arranged in a grape planting area; image recognition processing is performed, and index data of adult emergence hole crawling base, male to female ratio, trunk surface boring hole density, sap flow characteristic, grape tree foot area wood powder accumulation thickness, and fallen or suspended cylindrical boring debris distribution density are respectively counted and generated; each index is compared with a corresponding preset prevention and control starting threshold value, and when at least three indexes reach or exceed the threshold value, it is determined that the current time is a suitable time node for starting prevention and control measures. The application automatically captures the early representation of multiple dimensions of the bark beetle damage through the image recognition technology, realizes the accurate and objective determination of the prevention and control suitable period of the grape Dendroctonus valens, and provides a scientific basis for the intelligent prevention and control of the grape Dendroctonus valens.

A highly stackable modular flowerpot structure consists of stacked modules. Each module is formed by a deformed trunk with a base profile that is neither circular nor a regular polygon, having the same geometry as its upper profile but rotated by an angle ( ) and shifted by a height ( H) relative to the vertical axis. Connections between modules occur between the base profile of the upper module and the top profile of the lower module. This artificially designed twist creates preferred regions where the trunk surface is closer to the structure's axis. Arms that hold the substrate or flowerpot are located in these regions to: (i) be closer to the axis, improving stability; (ii) provide a larger cultivation area, increasing capacity; and / or (iii) create more space for plant growth. The resulting structure forms a single continuous surface with its arms distributed in a continuous rotating branch pattern.

This utility model provides an automotive trunk inspection tool, relating to the field of trunk inspection tool technology, to solve the problems of existing automotive trunk inspection tools having poor flexibility and weak adaptability, and failing to fit well with trunk molds. The tool includes a base plate; support frames are provided on both sides of the top of the base plate; a surface detection block is provided on a fixing component; the surface detection block is connected to an adjustment handle; a detection block A is provided on the top right side of the base plate; an insert A is bolted onto a mounting bracket; and an adjustable clamp is provided on the front side of the base plate. The surface detection block is flipped and stably connected to the fixing component via the adjustment handle, and is equipped with a contact sensor to contact the trunk surface. The trunk is inspected through the fitting component and the contact sensor on detection block A. The trunk is conveniently positioned using positioning components A and B, insert A, pins, and insert B. All components on the base plate are bolted together, facilitating adjustment of the installation position as needed.

This invention discloses a method for semi-wild cultivation of Dendrobium officinale, comprising the following steps: Step 1, seedling and substrate preparation: cutting sections of Pinus massoniana trunks, disinfecting and soaking them in pine needle extract, and then air-drying them for later use; selecting Dendrobium officinale seedlings, disinfecting and treating the roots with rooting agents for later use; Step 2, seedling planting and fixing: attaching the seedling roots to the bark surface of the trunk section, and covering the root attachment area with a moisturizing substrate; then fixing the seedling stems, leaves, and roots at corresponding positions on the upper and lower parts of the trunk section with fixing ropes; Step 3, movable hanging: hooks are pre-installed on the trunk section, and the trunk section is hung on a greenhouse, living tree branches, pergola, or wall embedded parts using the hooks; Step 4, cultivation period management: maintaining air humidity and trunk surface moisture through spraying, and regularly replenishing nutrients; Step 5, harvesting and trunk maintenance. This invention utilizes a section of Masson pine trunk as a movable epiphytic carrier, eliminating the need to rely on living trees or rock walls. By fixing the stems, leaves, and roots at the top and bottom respectively, it ensures plant stability, significantly improves cultivation flexibility and space utilization, and effectively enhances the survival rate and medicinal quality of Dendrobium officinale.

The invention relates to a caterpillar type birch juice collecting machine suitable for forest land, and belongs to the technical field of forestry machinery. The invention is used to solve the problems of low work efficiency, high labor intensity, difficulty in adapting to complex forest land topography and low automation degree in the prior art. The invention comprises a juice collecting mechanism, a drilling mechanism, a clamping mechanism, a lifting mechanism, a storage box and a caterpillar chassis mechanism. The caterpillar chassis mechanism is provided with the lifting mechanism at the front end and the storage box at the rear end.

The lifting mechanism is used to adjust the working height of the juice collecting mechanism, the drilling mechanism and the clamping mechanism. The clamping mechanism is used to clamp and position the trunk. The drilling mechanism is used to process and install holes on the trunk surface. The juice collecting mechanism is used to collect and install the birch juice. The storage box is used to store the collected birch juice. The invention is used for birch juice collection.

This makes it possible to more comprehensively measure the trunk surfaces of trees within the measurement range while generating travel routes that minimize travel time. [Solution] The system includes a tree position acquisition unit 102 that acquires tree position information of trees within a designated area, a grouping unit 104 that groups trees based on the tree position information acquired by the tree position acquisition unit 102, a virtual wall setting unit 106 that sets a virtual wall connecting the trees grouped by the grouping unit 104, and a path generation unit 107 that generates a movement path for measuring the state of the trees from the side using a measuring instrument. The path generation unit 107 generates a movement path that follows both sides of the virtual wall set by the virtual wall setting unit 106.
