[0002] The main manifestation of tobacco seedling diseases is the high infection rate of tobacco seedlings in the seedbed period. Through research, it is found that the main reason is that pests such as mosquitoes, midges and aphids fly into the seedling-raising greenhouse to spread germs. Since the seedbed management processes such as sowing, thinning, leaf pruning, water and fertilizer, temperature and humidity require entering and leaving the greenhouse, the frequency of opening the greenhouse door is relatively high. To curb the spread and occurrence of this disease, it is necessary to do a good job in mosquito and midge prevention at the door of the flue-cured tobacco seedling-raising greenhouse, so as to keep pests out of the greenhouse, cut off the germ transmission route from pests, effectively prevent the spread of germs, and avoid the occurrence of seedling diseases; create a good seedbed environment for the flue-cured tobacco seedling-raising greenhouse to ensure the cultivation of high-quality disease-free tobacco seedlings.

Detailed implementation manners
[0019] The following further introduces the utility model in combination with the drawings and specific embodiments:
[0020] Embodiment:
[0021] Refer to Figure 1, this embodiment provides a mosquito-proof curtain structure for the entrance of a flue-cured tobacco seedling-raising greenhouse; it includes a greenhouse body 1; a door frame 2 is arranged on the front side of the greenhouse body 1; a large door is arranged on the door frame; a disinfection pool 3 is arranged on the ground in front of the door frame 2; an extension bracket 4 is also installed on the door frame 2; the projection size of the extension bracket 4 on the ground can cover the disinfection pool 3; at least two magnetic door curtains 5 are also installed on the extension bracket 4; the lower part of the magnetic door curtain 5 hangs on the periphery of the steps surrounding the disinfection pool 3. The extension brackets 4 in this embodiment are all made of aluminum alloy materials.
[0022] The disinfection pool 3 is a concave rectangular pool body structure, and its width size is the same as the width size of the door frame 2.
[0023] There are two pairs of extension brackets 4 in total, and each pair of extension brackets 4 includes a pair of horizontal rods 4A respectively installed on the upper and lower sides of the door frame 2; a vertical column 4B is installed between the extended ends of the two horizontal rods 4A; a connecting rod 4C is hingedly installed on the upper side of the vertical column 4B; the connecting rod 4C is arranged in a cantilever shape; the length of the connecting rod 4C is half of the width of the door frame 2; the magnetic door curtains 5 are respectively hung on the connecting rod 4C for setting; an auxiliary door curtain 9 is also detachably installed between the horizontal rod 4A, the vertical column 4B and the door frame. The auxiliary door curtain in this embodiment is mainly for side protection, so it is made of flexible material, and it is not necessary to use a magnetic door curtain to provide an access passage. In addition, the connecting rod 4C in this embodiment can adopt a folding rod or a straight rod structure.
[0024] The extension bracket 4 also includes a sealing top plate 4D; the sealing top plate 4D is installed in a cantilever shape on the upper side of the door frame 2; the size of the sealing top plate 4D is larger than the size of the disinfection pool.
[0025] Reinforcing rods are also arranged at the upper and lower sides of the vertical column 4B near the connecting rod 4C and the horizontal rod 4A respectively.
[0026] A number of first clamping heads 6 are arranged on the upper top surface of the disinfection pool 3 and the lower bottom surface of the sealing top plate 4D; the first clamping heads 6 are used for clamping and limiting the horizontal rod 4A and the connecting rod 4C.
[0027] The number of magnetic door curtains 5 on a single extension bracket 4 is at least two; the corresponding magnetic door curtains 5 at the ends of the two extension brackets 4 can be attracted and set. There are four magnetic door curtains in this embodiment, and their specifications are the same as the width size of the door frame, all of which are 1.8m * 2m structures. At the same time, the magnetic door curtains adopt a double-screen yarn structure.
[0028] A second clamping head 7 for clamping the vertical column 4B is also arranged on the large door.
[0029] In addition, it is also possible to consider setting up devices such as sprayers and ultraviolet lamps in the area enclosed by the disinfection pool, the extension bracket, the auxiliary curtain, and the magnetic curtain as a means to kill aphids remaining in this area.
[0030] In this embodiment, the utility model device has two states during use. The first state is when the operator does not need to carry a large equipment device into the shed. At this time, the extension bracket is unfolded, the connecting rod is clamped by the first chuck, and the four magnetic curtains naturally hang down. The operator first enters the closed structure at the position of the extension bracket and then opens the large door to enter the shed. During this process, after the magnetic curtain is lifted, it will quickly fall back to maintain the relative enclosure inside.
[0031] The second state is when the operator needs to carry large equipment into the shed. At this time, in order to avoid interference with the extension bracket, the connecting rod needs to be rotated inward first, and then the column is correspondingly rotated to a position close to the large door, and the column is clamped with the second chuck. Thus, the integration of the extension bracket with the door frame and the large door structure is achieved. At this time, opening the large door can more conveniently transfer the equipment into the greenhouse.
