Description

Technical Field

[0001] The utility model relates to the technical field of hydroponics, in particular to a special light-proof tube for hydroponics root zones. Background Art

[0002] With the development of the economy, the emergence of hydroponic technology is a new type of soilless plant cultivation method, also known as nutrient solution culture. Its core is to directly immerse the roots of plants in nutrient solution. This nutrient solution can replace the soil and provide plants with water, nutrients, oxygen and other growth factors, so that plants can grow normally.

[0003] However, the existing technology has found that the pipes used for hydroponics have the following problems during use:

[0004] 1. The existing pipeline is a common single-layer white PVC pipe, which is light-transmissive and prone to algae such as green algae;

[0005] 2. Dark PVC pipes are easily affected by light, which can easily cause the temperature inside the pipe to rise and affect the growth of the root system;

[0006] 3. The inside of the pipe is black. When flushing the pipe, it is difficult to tell how clean the inside is because of the black color.

[0007] 4. Because the inside of the pipe is smooth, the roots at the bottom grow horizontally, causing blockage and affecting the flow of nutrient solution;

[0008] 5. In open-hole cultivation, the sunlight shines through the planting holes onto the inner wall and absorbs heat, causing the temperature of the local area, space, and nutrient solution in the pipe to rise;

[0009] The pipes used in hydroponic technology are quite strict. Pure white pipes or pure black pipes will have an impact, and the inside of the pipes are relatively smooth. The lateral growth of the roots affects the flow of the nutrient solution. In order to ensure the normal growth of the plants, it is important to design a special light-proof pipe for the root zone of hydroponics. Utility Model Content

[0010] The utility model aims to provide a special light-proof tube for hydroponic root zone to solve the above-mentioned problem.

[0011] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special light-proof tube for hydroponic root areas, comprising a reflective radiation layer, a light-proof and light-isolating layer, a reflective cleaning layer, a serrated groove and a fixed hole, wherein the reflective radiation layer is the outer layer of the pipe, and the inner layer thereof is the reflective cleaning layer, a light-proof and light-isolating layer is arranged between the reflective radiation layer and the reflective cleaning layer, the inner bottom of the reflective cleaning layer is a serrated groove, and the fixed hole is opened on the upper opposite side of the serrated groove.

[0012] Preferably, the reflective radiation layer and the reflective cleaning layer are white PVC.

[0013] Preferably, the light-shielding and light-isolating layer is black light-proof PVC.

[0014] Preferably, the sawtooth grooves are protruding structures of the reflective cleaning layer.

[0015] Preferably, the set value holes are evenly arranged on the top of the pipeline.

[0016] The beneficial effects of the utility model are as follows: the pipe is formed by a two-machine co-extrusion two-color three-layer structure of PVC, the inner and outer layers are white PVC, the middle layer is black PVC, and the bottom of the pipe is a serrated groove to prevent the huge root system from blocking the flow of nutrient solution, making it easy to identify the degree of cleaning. The outer white can reduce the high temperature caused by sunlight on the pipe, and the middle light-proof and light-proof layer can prevent the formation of algae such as green algae in the pipe. At the same time, no light penetrates from the pipe wall to the bottom of the root system, which is conducive to the growth of the root system in a dark light environment. In open cultivation, the sunlight entering through the fixed value hole is not easy to cause a large change in local temperature and affect the normal growth of the root system.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model provides a special light-proof tube structure for hydroponic root areas, including a reflective radiation layer 1, a light-proof and light-isolating layer 2, a reflective cleaning layer 3, a serrated groove 4 and a fixed hole 5. The reflective radiation layer 1 is the outer layer of the pipe, the inner layer is the reflective cleaning layer 3, and an intermediate light-proof and light-isolating layer 2 is arranged between the reflective radiation layer 1 and the reflective cleaning layer 3. In the present embodiment, the reflective radiation layer 1 and the reflective cleaning layer 3 are white PVC, and the light-proof and light-isolating layer 2 is black PVC. Of course, other materials can also be used as long as the effects of the reflective radiation layer 1, the reflective cleaning layer 3 and the light-proof and light-isolating layer 2 are achieved. For example, two layers can use a gray PVC layer. The inner bottom is a serrated groove 4, which facilitates the flow of the nutrient solution, and the fixed holes 5 are evenly opened on the upper part of the pipe.

[0024] In the specific implementation of the utility model: the pipe adopts PVC double-machine co-extrusion two-color three-layer structure integrated molding, which is the existing technology. The inner and outer layers are the same white PVC, and the middle is opaque black PVC. The bottom of the pipe is a serrated groove, and the fixed holes are evenly arranged on the top of the pipe according to the fixed crop spacing requirements.

[0025] During the later cleaning, the white inside helps to identify the degree of cleaning. In open-hole cultivation, the sunlight shines into the pipe through the planting hole and the light is reflected out, which is not easy to cause a large change in the temperature of the internal irradiation area. The bottom of the pipe is a serrated groove to prevent the horizontal growth of the roots and cause blockage affecting the flow of nutrient solution. The white outside can reduce the increase in temperature inside the pipe caused by sunlight. Combined with the light-proof and light-isolating layer in the middle, the growth of algae such as green algae caused by light passing through the pipe wall is avoided. The roots are conducive to normal growth in a dark light environment.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
