Problems solved by technology

[0003] At present, in order to ensure the normal growth of plants, it is necessary to provide light to the plants through supplementary lights when cultivating plants. However, due to the high power of supplementary lights, the temperature in the incubator will increase after long-term lighting. , making the plants easy to wither and dehydrate, making the plants prone to heat damage, which can easily lead to the death of the plants. In addition, the plants will also inhibit the photosynthesis of the plants under high temperature irradiation, which will affect the normal growth of the plants, making the growth of the plants on the culture board uneven growth

Embodiment 1

[0020] refer to figure 1 , an intermittent illumination type plant tissue culture equipment based on the principle of reversible reaction, comprising a box body 1, the inner bottom of the box body 1 is fixedly connected with a culture plate 2, the inner wall of the box body 1 is fixedly connected with a supplementary light 3 through a fixed rod, and the box body 1. A bar-shaped cavity 4 is provided at the upper end, and the bar-shaped cavity 4 is filled with nitrogen dioxide and dinitrogen tetroxide mixed gas. The bottom of the bar-shaped cavity 4 is fixedly connected with a plurality of heat-conducting rods 5. Further, the nitrogen dioxide and four-nitrogen A reversible reaction can occur between nitrous oxide, and the reaction formula is: N 2 o 4 =2NO 2 (reversible), and the nitrogen dioxide is reddish brown, and the nitrogen tetroxide is colorless. When the temperature in the mixed gas rises, the reaction balance of the mixed gas proceeds towards the direction of nitrogen...

Embodiment 2

[0028] refer to figure 2, different from Embodiment 1, the upper end of the tank 1 is fixedly connected with a liquid storage tank 13, the inner bottom of the liquid storage tank 13 is rotatably connected with a rotating shaft 14, and the side wall of the rotating shaft 14 is fixedly connected with a plurality of stirring blades 15, and the inner wall of the tank 1 The liquid sprinkler pipe 16 is fixedly connected, and the inner wall of the slide chamber 7 is connected with the inner wall of the liquid sprinkler pipe 16 through the one-way liquid outlet pipe 17, and the inner wall of the slide chamber 7 is connected with the inner wall of the liquid storage tank 13 through the one-way liquid suction pipe 18, which needs to be explained What is more important is that the one-way liquid outlet pipe 17 only allows the nutrient solution to enter the sprinkler pipe 16 from the slide chamber 7, and the one-way suction pipe 18 only allows the nutrient solution to enter the slide cham...

Abstract

The invention discloses an intermittent illumination type plant tissue culture equipment based on a reversible reaction principle. The intermittent illumination type plant tissue culture equipment comprises a box body, a culture plate is fixedly connected to the bottom in the box body, a light supplementing lamp is fixedly connected to the inner wall of the box body through a fixing rod, and a strip-shaped cavity is formed in the upper end of the box body; and the strip-shaped cavity is filled with nitrogen dioxide and nitrogen tetroxide mixed gas, a plurality of heat conduction rods are fixedly connected to the bottom in the strip-shaped cavity, a transparent plate is fixedly connected to the inner wall of the box body, and a sliding plug cavity is formed in the transparent plate. According to the intermittent illumination type plant tissue culture equipment, the temperature on the culture plate rises to generate current on a thermoelectric power generation plate, then a magnet exciting coil is powered on, a permanent magnet column and a magnetic sliding plug attract each other, then the mixed gas in the strip-shaped cavity enters the sliding plug cavity, the mixed gas with the darkened color partially shields light emitted by the light supplementing lamp, and it is avoided that strong sunlight irradiates the culture plate for a long time, plants wither and dehydrate easily, and normal growth of the plants is affected.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to an intermittent illumination type plant tissue culture equipment based on the principle of reversible reaction. Background technique [0002] Plant tissue culture is an important method for biological research and plant breeding and reproduction. It can use a small amount of plant tissue for rapid propagation, high reproduction efficiency, and a large number of plant seedlings can be obtained in a short period of time. [0003] At present, in order to ensure the normal growth of plants, it is necessary to provide light to the plants through supplementary lights when cultivating plants. However, due to the high power of supplementary lights, the temperature in the incubator will increase after long-term lighting. , making the plants easy to wither and dehydrate, making the plants prone to heat damage, which can easily lead to the death of the plants. In addition, the ...
