Description

Technical Field

[0001] The utility model relates to the technical field of plant cultivation, in particular to a plant drip irrigation module and a system. Background Art

[0002] In indoor plant cultivation (including but not limited to indoor farms, film greenhouses, glass greenhouses, etc.), since the indoor space is a closed space, there is no frequent air exchange with the external environment, and plants need to consume a large amount of carbon dioxide and nutrients during photosynthesis, so it is necessary to supply carbon dioxide and nutrients to the plants in a timely manner. The current method is to directly fill the closed room with carbon dioxide, but since the density of carbon dioxide is higher than that of air, it will lead to the problem of uniform distribution of carbon dioxide concentration. At the same time, since the space in the entire closed room is large, the absorption efficiency of carbon dioxide is low. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0030] like Figure 1 - Figure 2 As shown, in one embodiment, a plant drip irrigation module and system specifically includes a gas unit 1, which is a hollow structure, and a gas inlet 2 and a gas outlet 3 are respectively provided at both ends thereof, and carbon dioxide can enter through the gas inlet 2 and be discharged through the gas outlet 3. It also includes a liquid unit 4 connected and fixed to the gas unit 1, and a liquid inlet 5 and a liquid outlet 6 are respectively provided at both ends of the liquid unit 4, and the liquid unit 4 is also a cavity structure, water and fertilizer are supplied through the liquid inlet 5, and excess water and fertilizer are discharged through the liquid outlet 6, and the liquid unit 4 is connected to the gas unit 1 through a plurality of openings 8, so that carbon dioxide can enter the cavity of the liquid unit 4, and then the carbon dioxide and water and fertilizer are discharged to the roots of the plants through the dripping port 7 provided below, so as to ensure that the carbon dioxide concentration at the roots of the plants meets the growth requirements while not requiring the entire indoor space to be filled with a certain concentration of carbon dioxide.

[0031] Furthermore, the cavity of the liquid unit 4 is filled with a sponge, which can absorb water and fertilizer, and effectively reduce the speed of water and fertilizer dripping from the dripping port. The density of the sponge is 30-40 kg / m 3 The pressure of carbon dioxide is 0.2-0.4Mpa. When carbon dioxide is discharged from the dripping port 7, it can also promote the dripping of water fertilizer. At the same time, after water fertilizer and carbon dioxide are mixed, the mixed liquid is acidic, which is more suitable for the growth of plants such as strawberries.

[0032] The size of the entire drip irrigation module is 100*50*80mm, which is more compact than the existing 500m 3 If carbon dioxide is controlled in indoor spaces such as greenhouses, regulation will be faster.
