The invention belongs to the technical field of agricultural biology, and provides a soybean nodulation and nitrogen fixation related gene and application of an encoding protein thereof, the nucleotide sequence of the gene Gm02g072800 is shown as SEQ ID NO: 1, or a variant sequence which encodes the same functional protein and has homology greater than or equal to 90%; the amino acid sequence of the protein coded by the gene Gm02g072800 comprises a conservative AP2 structural domain, belongs to an ERF transcription factor family, is positioned in a cell nucleus, and has the functions of promoting soybean root nodule development and symbiotic nitrogen fixation. According to the invention, the specific expression of the gene in the soybean middle column and root nodule endodermis is determined, and a target gene is provided for cultivating soybean varieties with high nitrogen fixation efficiency.

The utility model discloses leachate pipeline anti -leakage buffer device and leakage early warning system, including pipeline body and two flanges, the circumferential outer wall of pipeline body is provided with buffer mechanism, buffer mechanism includes endodermis and outer membrane, the endodermis sets up the circumferential outer wall of pipeline body, forms the buffer cavity between endodermis with outer membrane, the inner wall of buffer cavity is provided with a plurality of equidistance arrangement's diaphragm, the inner wall of buffer cavity is provided with a plurality of equidistance arrangement's liquid collecting port, and one end of liquid collecting port is provided with collecting pipe. The utility model discloses leachate pipeline anti -leakage buffer device and leakage early warning system have the effect that promote pipeline anti -leakage ability.

The utility model discloses a multifunctional injection needle for cataract surgery, which is provided with a Helon water injection needle body, the water injection needle body is a bent metal needle, and the water outlet part of the needle point part is of an annular structure, and is characterized in that the bent part is positioned at the one third part of the needle point part close to the needle point part, and the bent part is in a smooth transition form; the outer ring at the water outlet is arranged in a fillet manner to form a smooth surface, and the smooth surface is precisely polished by a grinding wheel or an abrasive belt to form a frosted surface, The utility model has the advantages that the device can be used immediately after being opened, the operation is safer, particularly, the possibility of scratching the posterior capsule of the crystal, the cornea epithelium and the endodermis is greatly reduced, the operation safety is increased, and the operation efficiency is improved. The polisher has the functions of polishing and viscoelastic agent filling, avoids the problem that a common polisher frequently enters and exits an incision, so that the risk that the incision is torn and infected is increased, improves the polishing efficiency, and meanwhile is extremely low in manufacturing cost.

The invention relates to the technical field of image recognition, in particular to a fungal focus sketching method for fungal keratitis under a microscope, which comprises the following steps: acquiring microscopic images of epithelium, matrix layer and endodermis of different depths of a cornea sample; analyzing the influence range of fungal spores according to the gray level distribution characteristics of the microscopic image of the epithelium, and obtaining an undetermined focus connected domain of the epithelium; analyzing the interweaving condition of the highlight part according to the edge distribution characteristics of the microscopic image of the matrix layer to obtain an undetermined focus connected domain of the matrix layer; analyzing regularity and permeability of cells according to transparency characteristics of the microscopic image of the endodermis to obtain a to-be-determined focus connected domain of the endodermis; fusing the to-be-determined focus connected regions of the epithelial layer, the matrix layer and the endothelial layer, and sketching a fungal focus region corresponding to the cornea sample. The influence of nerve fibers on fungal lesion recognition can be avoided, and the accuracy of a fungal lesion sketching result is improved.
