The application discloses a kind of difficult stand beach intertidal alien mangrove plant Laganum community transformation method, belong to mangrove planting technical field;Steps include: S1, mangrove present situation investigation;S2, beach protection repair measure;S3, Laganum pruning or felling;S4, plant mangrove forest;S5, management and protection;S6, effect evaluation;The method can be grown to Laganum community renewal reconstruction in seawater scouring area, avoid reconstruction failure risk, compared with other conventional methods reconstruction repair early canopy forestation;After taking beach protection measure, the beach of repair area is stable, avoid being lost by tidal scouring and leading to sediment;Use old fishing net to protect, avoid that marine litter enters repair area;Use small block to level, keep original Laganum root system, there are few biologicals in woodland in early reconstruction period, such as crab, reduce the interference and damage to new planting seedling, guarantee mangrove seedling survival rate;Using seedling planting that is cultivated under the condition of high salinity environment, seedling resistance is strong, recovery growth speed is fast, survival rate is high.

This invention discloses a mangrove planting and protection device and construction method in a fishpond reclamation area. The device includes a settlement adaptation component and a root fixing component. The settlement adaptation component consists of an outer frame, an inner sliding frame, and a drop-reducing unit located at the top. The outer frame is anchored in the reclamation sediment, and a settlement visual marker structure is set on its inner side to indicate the settlement stage of the inner sliding frame. The inner sliding frame can slide vertically along the inner wall of the outer frame to adapt to the sediment settlement. The root fixing component is used to fix the seedlings and provide a growth substrate. The construction method is as follows: the device for planting seedlings is mounted on a drone and accurately placed in the target reclamation area. The device penetrates the soft mud through its bottom structure. During the sediment consolidation and settlement process, the inner sliding frame slides down along the inner wall of the outer frame, achieving synchronous settlement of the roots and the mud surface, effectively preventing root damage and seedling lodging caused by differential settlement.

The utility model discloses a kind of fungicide application devices suitable for coastal mudflat mangrove, it is related to plant cultivation technical field, the utility model includes fixed ring, the outside of fixed ring is fixedly connected with several bolt seats, the inner wall of several bolt seats is all rotatably connected with bolt, the outer wall of several bolts is all rotatably connected with bolt seat two, the utility model is provided with rotating wheel, first several bolts are rotated and disassembled, fixed ring can be separated with fixed ring two respectively, then fixed ring and fixed ring two are covered with mangrove trunk in fixed position, then several bolts are reset fixed, it can be achieved that even when mangrove gradually thickens due to growth, the whole equipment can be kept with trunk fixed installation, prevent the installation position of equipment from displacement due to external force factor, and then cause the equipment to continue normal use.

This invention relates to the field of water conservancy and hydropower engineering, and particularly to a method for assessing the ecological water requirement of mangrove plants. The method includes: selecting the *Prunus mume* species with the highest area proportion in the mangrove community as the target species within a target area; determining the habitat requirements of the target species during sensitive growth and development stages, and selecting factors sensitive to flow rate changes as habitat suitability indicators, including salinity and immersion time; constructing a three-dimensional temperature-salinity coupled hydrodynamic model, including three-dimensional hydrodynamic control equations, temperature transport control equations, and salinity transport control equations, to simulate the salinity and immersion time in the target species' distribution area under different flow rate conditions; and based on the simulated salinity and immersion time results, combined with a pre-set threshold range for habitat suitability indicators, using the flow rate corresponding to the upper limit of the threshold range as the ecological water requirement of the mangrove plants.

This application relates to the technical field of visual recognition, and in particular to a method for detecting frost damage to mangrove plants based on visual recognition. The method includes acquiring an image sequence; extracting the main vein of the leaf in the first frame as an anchor point; calculating the transformation matrix of subsequent frames relative to the anchor point to obtain a registered image sequence; calculating the temporal variance of the registered image sequence to generate a static baseline image; extracting the leaf outer contour and the connected domain of the lesion to generate a distance gradient field; calculating the mean distance of the connected domain of the lesion in the distance gradient field and the area ratio of the connected domain in the outermost gradient band, and extracting the morphological features of the connected domain of the lesion, thereby dividing the connected domain of the lesion into saline-alkali withered areas or frost damage candidate areas; cropping image blocks corresponding to the frost damage candidate areas from the static baseline image after removing the saline-alkali withered areas, inputting them into an artificial neural network to extract features, and outputting the damage level. This application aims to effectively distinguish between saline-alkali withering and true frost damage to mangrove plants by decoupling and removing dynamic water wave artifacts through spatiotemporal feature decoupling.
