This invention relates to the field of sediment remediation, and more particularly to a device for treating river and lake sediment. Existing devices are inconvenient for judging the thickness of river and lake sediment during use, making it difficult to inject liquid bacteria into sediment of varying thicknesses, resulting in uneven distribution of the liquid bacteria. This invention includes a hull, with a mounting base fixedly connected to the bottom of the hull. A feed hopper is fixedly connected to the mounting base, and a hollow tube is rotatably connected to the lower part of the feed hopper. This invention uses a disc positioned on top of the river and lake sediment, allowing a guide pipe, threaded rod, and agitator to enter the sediment. An appropriate amount of liquid bacteria is then added to the feed hopper. This allows for the injection of liquid bacteria into sediment of varying thicknesses while minimizing dilution by the water, thus improving the treatment effect of river and lake sediment.

This invention relates to the field of gas detection technology and discloses an intelligent gas concentration detection device, including a detection box with a gas chamber inside. The gas to be tested is delivered into the gas chamber, and a detection mechanism is installed inside the gas chamber. An adjustment mechanism is also installed inside the gas chamber to isolate and expel air from the gas chamber before the gas to be tested is introduced. By setting up the adjustment mechanism, this invention isolates and expels air at the detection position inside the gas chamber before the gas to be tested enters for detection, thus reducing the dilution of the gas to be tested by air during the detection process.

This invention relates to a method for image classification and recognition of dragon fruit stem and leaf diseases based on an improved MSF-Net, belonging to the field of agricultural disease image recognition technology. Addressing the problems of existing methods' low discrimination between minor and similar diseases of dragon fruit stems and leaves, and the lack of specific adaptation for multi-scale feature fusion, this invention inputs stem and leaf images into an improved MSF-Net model, which includes parallel first and second feature extraction channels. The first feature extraction channel is composed of multiple cascaded multi-scale convolutional modules, containing convolutional branches of different sizes connected to CReLU activation layers. The second feature extraction channel is composed of multiple cascaded dilated multi-scale convolutional modules, containing convolutional branches with different dilation rates connected to CReLU activation layers. The output features of the two channels are concatenated along the channel dimensions to obtain a multi-scale fused feature map, which is then global average pooled and fed into a fully connected classification layer to output the disease category. This invention can enhance the ability to capture subtle lesions and differences in disease stages, and can be used for real-time disease identification and control in dragon fruit plantations.

The application discloses a preparation method of MICP combined with molasses reinforced calcareous sand. The preparation method comprises the following steps: activating and culturing mineralization bacteria, preparing a molasses culture medium by using waste molasses, inoculating the activated mineralization bacteria liquid on the molasses culture medium, and after the OD600 value of the mineralization bacteria in the molasses culture medium is between 1.0 and 1.5, injecting the molasses culture medium containing the mineralization bacteria into the calcareous sand for reinforcement, so that the reinforced calcareous sand is obtained. The preparation method of the MICP combined with molasses reinforced calcareous sand disclosed by the application directly uses waste molasses as a carbon source to culture mineralization bacteria, greatly reduces the preparation cost, and is green and environment-friendly in the preparation process; by adding sugarcane residue with a proper proportion and length in the waste molasses, the viscous sugar silk and the sugarcane residue are uniformly distributed in the reinforced calcareous sand, so that the generation amount of the microbial-induced calcium carbonate crystal is improved, and the prepared calcareous sand has more excellent reinforcement effect, and the unconfined compressive strength can reach 2 MPa at most.
