Technical Problem

[0004]为了克服现有技术的不足,本实用新型提供温室菊花二氧化碳补给装置,能解决以下的技术问题:采用空气施肥法时,因为二氧化碳比空气重,从上方排放后,二氧化碳会自然下沉,均匀分布在植物周围,包括根部,从而提高光合作用效率,如果从较低的位置排放二氧化碳,二氧化碳实际上是围绕在根部周围的,如果一直放置在一个较高的位置排放二氧化碳,会导致二氧化碳在排放过程中向四周逸散,降低植株周围二氧化碳浓度提高的效率;因此随着植株的长高,如果排放的高度还是处于较低的位置,会导致菊花植株周围的二氧化碳分布不均匀而影响菊花的成长效率

Description

Technical Field

[0001] This utility model relates to the field of greenhouse chrysanthemum cultivation, and in particular to a carbon dioxide supply device for greenhouse chrysanthemums. Background Technology

[0002] Carbon dioxide fertilization is an agricultural technique that enhances the efficiency of plant photosynthesis by increasing the concentration of carbon dioxide in the environment. In a closed greenhouse environment, artificially increasing carbon dioxide can effectively make up for the carbon demand gap of crop photosynthesis, thereby meeting the needs of crop photosynthesis and improving yield and quality.

[0003] Throughout its growth process, chrysanthemums continuously produce organic matter through photosynthesis to support their growth and development. Carbon dioxide is the primary carbon source for photosynthesis and significantly impacts the photosynthetic rate. The carbon dioxide content in the air typically accounts for 0.033% of its volume; when the carbon dioxide content increases to 0.3%, photosynthesis strengthens. However, because greenhouses are usually well-sealed in winter, air exchange is often limited, resulting in insufficient carbon dioxide levels for photosynthesis. According to experimental data, chrysanthemums can grow well, produce large flowers, and mature one to two weeks earlier at a carbon dioxide concentration of 700-900 ppm. The carbon dioxide concentration requirements of chrysanthemums at different growth stages are as follows: 400-500 ppm is suitable for the seedling stage, 800-1000 ppm is suitable for the growth stage, and 600-800 ppm is suitable for the flowering stage. When using the air fertilization method, because carbon dioxide is heavier than air, it will naturally sink and be evenly distributed around the plant, including the roots, after being emitted from above, thereby improving the efficiency of photosynthesis. If carbon dioxide is emitted from a lower position, it will actually surround the roots. If the carbon dioxide is always emitted from a high position, it will cause the carbon dioxide to escape in all directions during the emission process, reducing the efficiency of increasing the carbon dioxide concentration around the plant. Therefore, as the plant grows taller, if the emission height is still at a low position, it will lead to uneven distribution of carbon dioxide around the chrysanthemum plant, thus affecting the growth efficiency of the chrysanthemum. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a carbon dioxide supply device for greenhouse chrysanthemums, which can solve the following technical problems: When using air fertilization, because carbon dioxide is heavier than air, it will naturally sink and be evenly distributed around the plants, including the roots, after being emitted from above, thereby improving photosynthetic efficiency. If carbon dioxide is emitted from a lower position, it will actually surround the roots. If carbon dioxide is always emitted from a higher position, it will cause the carbon dioxide to dissipate in all directions during the emission process, reducing the efficiency of increasing the carbon dioxide concentration around the plant. Therefore, as the plant grows taller, if the emission height is still at a low position, it will lead to uneven distribution of carbon dioxide around the chrysanthemum plant, thus affecting the growth efficiency of the chrysanthemum.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a greenhouse chrysanthemum carbon dioxide supply device, including a greenhouse support column, the greenhouse support column including a buckle structure fixed on the greenhouse support column, a support plate provided on the buckle structure, a support stud passing through the support plate, an adjusting nut located above the support plate being threaded to the outer side of the support stud, a rectangular frame being connected to the top of the support stud, an M-shaped block being provided on the inner side of the rectangular frame, an exhaust pipe being provided at the bottom of the M-shaped block, a nozzle being provided at the bottom of the exhaust pipe, a gas flow valve being provided in the middle part of the exhaust pipe for regulating the gas flow, and a three-way interface being connected to the top of the buckle block, with a connecting hose being provided between two adjacent three-way interfaces.

[0006] As a preferred technical solution of this utility model, a fixing knob is threaded through the front end of the M-shaped block, and the fixing knob contacts the rectangular frame after passing through the M-shaped block.

[0007] As a preferred technical solution of this utility model, the buckle structure includes a buckle plate, which is sleeved on the outside of the greenhouse support column, and fixing bolts are provided at both ends of the buckle plate. The fixing bolts pass through the fastening plate and are threadedly connected to the fixing nut.

[0008] As a preferred embodiment of this utility model, the inner sides of both the fastening plate and the clamping plate are provided with anti-slip rubber.

[0009] In a preferred embodiment of this utility model, the support plate is fixed to the top of the card plate, and a first rib is provided between the top surface of the card plate and the support plate.

[0010] As a preferred embodiment of this utility model, a second rib is provided between the inner bend of the support plate and the side of the card plate.

[0011] As a preferred embodiment of this utility model, the M-shaped block consists of a card block and card slots formed on both sides of the card block.

[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. By adjusting the height of the buckle structure on the outside of the greenhouse support column, and by adjusting the position of the adjusting nut on the outside of the support stud, the height of the rectangular frame will rise or fall after the adjusting nut is placed on the support plate. This allows the nozzle to adjust its height according to different growth stages. As the plant grows taller, the emission height also increases, resulting in a more even distribution of carbon dioxide around the chrysanthemum plant and promoting high-quality chrysanthemum growth. 2. The M-shaped block, which is clipped onto the outside of the rectangular frame, allows the discharge pipe to rest on the rectangular frame and slide inside the frame. The position of the M-shaped block is fixed by a fixing knob, thereby adjusting the position of the discharge pipes according to the placement distance of the chrysanthemums.
