The utility model belongs to the technical field of seed germination observation, especially is involved in an agricultural seed germination observation box. The technology includes the box, be provided with a plurality of baffle in the box, the baffle divides the box into a plurality of for placing the compartment of seedling tray, the top of box is covered with the installation shell, is equipped with a plurality of first through -hole that communicates with the installation shell connection in the box, two pieces of reflector plate are fixed in the top of installation shell, the left and right inner side wall of installation shell all are equipped with the light source board, the front reflector plate is used for the light of left light source board reflection into the box, the back reflector plate is used for the light of right light source board reflection into the box. Start light source board, two pieces of light source board emit light, the light is reflected and irradiated into the compartment through the reflector plate in the installation shell, only two pieces of light source board are used in a box, compared with the light source board of each compartment of existing installation reduces the cost. Through the light reflection and the heat conduction principle of water to improve the automation of seed germination observation box.

Frame for supporting a head-mounted display on a user, comprising: a first portion positioned for a first user's eye, comprising: a first casing for optical components, the first casing comprising: a first casing reflector mount for a first casing reflector; a first back mount for a back reflector, the back mount defining a plane for the back reflector and a corresponding back reflector axis perpendicular to the plane; a first front mount for a combiner, the front mount defining a plane for the combiner and a corresponding combiner axis perpendicular to the plane; the back mount positioned to position the back reflector in close proximity to the user's first eyebrow; the casing comprising: a second portion positioned for the other eye, comprising: a second casing for a second optical component, the second casing comprising: a second casing reflector mount for a second casing reflector; and A second back mount for the back reflector, the back mount defining a plane for the back reflector and a corresponding back reflector perpendicular to the plane; a second front mount for the second combiner for the other eye, the front mount defining a plane for the combiner and a corresponding combiner axis perpendicular to the plane; the second back mount is positioned to position the second back reflector close to the user's other eyebrow, and as a result the second casing extends from the inner end close to the other eyebrow. A frame is disclosed comprising: a second portion having an outer end adjacent to the other temple of the ser; a bridge member having an extension between the first casing and the second casing, thereby defining a frame transverse axis, and being positioned to be mounted substantially parallel to the user's cross-section; the frame transverse axis having an X-axis perpendicular thereto for alignment with the user's forward-looking axis when mounted, and each of the back mounts and each of the front mounts extending downward from the bridge member.
