Description

TECHNICAL FIELD

[0001] The application relates to the technical field of seedling cultivation, and particularly relates to a high-survival-rate water culture device for highway planting seedlings based on containerization. BACKGROUND

[0002] As a core framework of the national traffic network, the greening project of the highway has important significance for improving the ecological environment along the line, reducing noise pollution and improving driving safety. In order to cultivate the seedlings required by the greening project, the current seedling cultivation is mainly carried out in the way of water culture. The water culture has the advantages of fast growth speed, good quality, more cleanliness and space saving. However, the following problems are prone to occur during the water culture:

[0003] 1. The survival rate of seedlings is low during water culture. The current nutrient solution for water culture is mainly replaced by artificial periodic replacement, and the nutrient solution is in a non-flowing state. The oxygen content in the nutrient solution is reduced, which causes the root system to have difficulty in breathing. The nutrient elements in the nutrient solution are precipitated, which causes the seedlings to be unable to uniformly absorb nutrients. Algae and harmful bacteria breed, which causes the seedlings to have rotten roots, thereby affecting the survival rate of the water culture seedlings.

[0004] 2. The ventilation effect is poor in the water culture environment. Most of the current water culture devices are placed in a greenhouse environment, and lack of ventilation for the seedlings. The air flowability around the seedlings is poor, which causes the seedlings to be unable to be timely or effectively supplemented with carbon dioxide gas, so that the healthy and rapid growth of the seedlings cannot be guaranteed.

[0005] 3. The seedlings are prone to side tilting, tilting or abnormal growth during water culture. The current water culture device lacks an intervention device for the growth of the seedlings, especially for the cultivation of climbing seedlings (such as ivy seedlings). With the growth of the climbing seedlings, the climbing seedlings are not intervened in time, which causes the climbing seedlings to have side tilting, tilting or abnormal growth (growth in a direction different from the predetermined direction). It is difficult to correct the climbing seedlings in the later period, and the cultivation of the climbing seedlings is prone to failure. SUMMARY

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1 to 6 As shown, a containerized hydroponic device for high survival rate of highway planting seedlings is provided. It is used for cultivating seedlings required for highway greening vegetation, such as shrubs like privet or other plants. Specifically, it includes a vertical frame 1 (2.5m high, 1.5m wide), a hydroponic circulation system at the bottom of the vertical frame 1, and multiple layers of hydroponic layers spaced vertically above the hydroponic circulation system. Figures 1 to 3 The hydroponic system consists of three layers (50cm apart); the hydroponic circulation system includes a water tank 2 (500L capacity), a water pump 3 (20L / h flow rate) installed above the water tank 2, water inlet pipes 4 leading from the water tank 2 and into the left end of all hydroponic layers, and return pipes 5 leading from the right end of all hydroponic layers and returning to the water tank 2; the hydroponic layers include a cultivation box 6 (1.5m × 0.5m × 0.3m, HDPE material) and multiple root isolation nets 7 (304 stainless steel mesh, 2mm mesh diameter) extending vertically from the top of the cultivation box 6 into the cultivation box 6. Figures 5 to 6The water supply pipe 4 connects to the incubator 6 via an inlet (water inlet 8), and the return pipe 5 connects to the incubator 6 via an outlet (return outlet 9). The bottom of the root isolation net 7 is positioned at a height higher than the inlet 8 but lower than the return outlet 9 (the bottom of the net is 10cm from the inlet 8 and 20cm from the return outlet 9). A water pump 3 continuously drives the water in the incubator 6 to circulate from the inlet 8 to the return outlet 9 (flow rate 0.01m / s). This technical solution sets a certain height difference between the inlet 8 and the return outlet 9. Water enters through the inlet 8 and exits when the water level reaches the height of the return outlet 9. The water pump 3 continuously drives the water in the incubator 6 to circulate from the inlet 8 to the return outlet 9, increasing the oxygen content in the water, preventing nutrient precipitation, inhibiting algae and harmful bacteria growth, and thus improving the survival rate of seedlings.

[0043] like Figure 6 As shown, in order to further reduce the water flow rate in the cultivation box 6, multiple vertically arranged and linearly arrayed water-blocking plates 10 (PVC material, height 25cm, flow channel width 3mm, spacing 10cm) are fixed in the cultivation box 6. Each water-blocking plate 10 has multiple vertically arranged flow channels (width 2-4cm) to reduce the water flow rate and ensure that the roots fully and evenly absorb nutrients.

[0044] like Figure 4 As shown, in order to ensure the pressure balance of the circulation system, the hydroponic circulation system also includes a flow control valve 11 (such as a gate valve) installed on the water inlet pipe 4 and a flow control valve 12 (such as a gate valve) installed on the return water pipe 5. The two flow controls work together to maintain a constant water inlet and return flow. The cooperation of the two valves can eliminate dynamic imbalance and ensure the pressure balance of the circulation system.

[0045] Continue as Figure 4 As shown, in order to purify the water, the hydroponic circulation system also includes a filter 13 (a Y-type filter 13 with a precision of 100 mesh) installed on the return water pipe 5. It is checked once a week to fully filter root secretions, particles and other impurities, thereby purifying the water.

[0046] like Figure 7 As shown, an air supply system is also installed above each hydroponic layer; the air supply system includes an air supply channel 14 running horizontally above the incubator 6 and a fan 15 (air volume 10m³ / h) connected to the right end of the air supply channel 14. 3 / h) and an air nozzle 16 (8mm diameter) located at the bottom of the air supply channel 14 and facing the root isolation net 7. The air supply system supplies air into the air supply channel 14 by the fan 15, and the air nozzle 16 (wind speed 0.3m / s) blows air into the seedlings in the root isolation net 7. This not only provides carbon dioxide gas to the seedlings, but also reduces local humidity, ensuring the healthy and rapid growth of the seedlings.

[0047] like Figure 8 As shown, the air supply system also includes a seedling rack that is detachably (by thread) installed on the air supply nozzle 16; the seedling rack includes an extended air supply pipe 17 concentrically connected to the air supply nozzle 16, and multiple climbing pipes 18 circumferentially arrayed and connected to the side wall of the extended air supply pipe 17 and extending into the inner cavity of the root isolation net 7. Figure 8 The system comprises three climbing pipes 18 and multiple climbing protrusions 19 vertically connected to the sidewalls of the climbing pipes 18 and arranged in an array along the axial direction of the climbing pipes 18. The bottom of the extended air supply pipe 17 has an air outlet (6mm in diameter) corresponding to the root isolation net 7. The climbing pipe 18 is hollow inside, with an air outlet (2mm in diameter) at its bottom extending into the inner cavity of the root isolation net 7. The climbing pipe 18 is tightly attached to the sidewall of the root isolation net 7. When cultivating climbing seedlings (such as wisteria), the seedlings can grow upwards along the climbing pipes 18, and the climbing protrusions 19 effectively ensure the adhesion of the seedlings. Furthermore, not only can the extended air supply pipe 17 supply air to the seedlings, but the climbing pipe 18 can also inject air into the water to increase the oxygen content in the water, preventing root immersion and oxygen deficiency, and promoting nutrient absorption.

[0048] Continue as Figure 8 As shown, to further ensure the fixation of the seedlings, the seedling rack also includes a seedling fixing ring 20 located at the center of all climbing tubes 18, and multiple positioning hooks 21 connected to the side walls of the seedling fixing ring 20 and distributed in a circumferential array; the number of positioning hooks 21 is equal to the number of climbing tubes 18, with three in each case. Each positioning hook 21 is suspended on the climbing tube 18 and supported on the climbing protrusion 19. Figure 8 There is only one seedling fixing ring 20, but multiple rings can also be installed. The number of seedling fixing rings 20 can be flexibly increased or decreased according to actual needs. The seedlings are introduced into the seedling fixing rings 20 to further fix them and prevent them from tilting or falling over. Rotating the seedling fixing rings 20 counterclockwise will disengage the positioning hooks 21 from the climbing tubes 18, thus easily disassembling the seedling fixing rings 20. It is very convenient to use.

[0049] like Figure 7 As shown, to supplement lighting, supplemental lighting lamps 22 are installed above each hydroponic layer, facing the root isolation net 7. These are LED lamps with a red:blue spectrum of 3:1 and a light intensity of 100 μmol·m⁻¹. -2 ·s -1 It is open for 12 hours a day (6:00-18:00).

[0050] like Figure 9As shown, to facilitate seedling cultivation in winter, a heating system is installed on the upper left side of the water storage tank 2. The heating system includes a heating pipe 23 leading out from the water storage tank 2, a heating pump 24 connected to the heating pipe 23, a heater 25 connected to the heating pump 24, and a second heating pipe 26 connected to the heating pump 24 and returning to the water storage tank 2. The heating pump 24 draws water from the water storage tank 2, and after heat exchange with the heater 25, the water in the water storage tank 2 is heated. This system is suitable for winter use, as it can increase the ambient temperature around the seedlings and prevent the seedlings from freezing.

[0051] Continue as Figure 9 As shown, to facilitate the addition of various nutrient solutions during seedling cultivation, a nutrient solution supply system is also provided at the left end of the water storage tank 2. The nutrient solution supply system includes a hanging box 27, five supply boxes 28 (capacity 5L) fixed below the hanging box 27 and linearly arranged along the length of the hanging box 27, five supply pumps 29 fixed to the side of the hanging box 27 and linearly arranged along the length of the hanging box 27, five injection ports 30 located on the side of the hanging box 27 and connected to the supply boxes 28, a first supply pipe 31 connecting the supply pumps 29 and the supply boxes 28, and a second supply pipe 32 connecting the supply boxes 28 and the water storage tank 2. Concentrated nutrient solutions such as calcium nitrate, potassium nitrate, and other trace elements are temporarily stored in the supply boxes 28 and replenished once a day by the supply pumps 29. The nutrient solutions can then be directly mixed into the water storage tank 2. Since the water in the water storage tank 2 is continuously circulating, the nutrient solutions will be quickly mixed after entering the water storage tank 2.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
