Description

A cultivation system and method for Plantago spp. Technical Field

[0001] The invention relates to the technical field of cultivating plants of the genus Plantago, in particular to a cultivating system and a cultivating method of plants of the genus Plantago. Background Art

[0002] Plants in the genus Water Plantain are extremely sensitive to their environment and are good indicator species. However, due to uncertain water clarity, unstable water quality, and the presence of large amounts of soil, it is difficult for germinating seedlings to grow into plants taller than 10 cm. As a result, this genus is endangered and has been listed as a Class II protected plant in China.

[0003] During the seedling stage, submerged plants are very small, so they secrete relatively small amounts of allelopathic substances. These small amounts of allelopathic substances promote the growth of unicellular algae and filamentous algae. Unicellular algae and filamentous algae will initially adhere to the seedlings of these plants. At the same time, because unicellular algae reproduce very rapidly, the nutrient solution in the cultivation tank will be quickly consumed by the large number of unicellular algae that reproduce. This is not only detrimental to the growth of the Plantago plants we are cultivating, but also causes competition, thus affecting the normal growth and reproduction of the Plantago plants.

[0004] Therefore, there is an urgent need to develop a system and method suitable for cultivating plants of this genus.

The specific control method is a prior art and will not be described in detail in this application. The cultivation pool 1 is powered by solar photovoltaic modules. The water quality in this application needs to meet the standard of Class III water in the surface water environmental quality standard GB3838, that is, it is mainly suitable for centralized drinking water surface water source secondary protection areas, fish and shrimp wintering grounds, migration channels, aquaculture areas and other fishery waters and swimming areas.

[0036] A water inlet 8 and an overflow port 9 are provided on the inner wall of the cultivation tank 1. The height of the overflow port 9 is smaller than that of the water inlet 8. A drainage and mud discharge port 10 is provided at the bottom of the cultivation tank 1. The drainage and mud discharge port 10 is connected to a drain valve. The drainage and mud discharge port 10 is connected to the drain valve through a thread or a flange.

[0037] The liftable cultivation module 2 includes a lifting component 201 and a seedling tray 202. The lifting component 201 includes at least two sets of lifting rails and sliders symmetrically arranged on the inner wall of the cultivation pool 1. The slider is connected to a lifting platform and a lifting drive device. The lifting drive device in this embodiment is electrically driven. At least 6 seedling trays 202 are arranged on the lifting platform, which can be 6, 8, 10 or 12, etc., depending on the size of the actual cultivation pool 1. Each seedling tray 202 is provided with a culture medium, and the density of the culture medium is greater than the density of the water body; controlling the density of the culture medium to be greater than the density of the water body can prevent the culture medium from floating in the water body. Specifically, the culture medium in the present invention includes 30-50wt% organic fertilizer (preferably 40wt%), 30wt% river sand and 20-40% gum arabic (preferably 30wt%). The average diameter of the river sand is 0.1mm, and the density of the culture medium is 1.2-1.5g / cm 3 The organic fertilizer is prepared as follows: 66wt% sludge; 33wt% sawdust; 0.49wt% supercalcium; 0.33wt% urea; 0.17wt% potassium fertilizer; and 0.1wt‰ fermentation bacteria (organic fertilizer fermentation agent produced by Shandong Sukehan Bioengineering Co., Ltd.). After 10 days of fermentation, 1.1wt% potassium sulfate or potassium chloride and 1.4wt% urea are added. The mixture is stirred, left to stand for 5-7 days, and then crushed and granulated into fertilizer. Gum arabic is mainly used to lock the culture medium, while river sand can increase the density of the culture medium and also provide some nutrients.

[0038] Specifically, the lifting platform is provided with at least 6 grooves for placing the seedling tray 202, the depth of the grooves is less than the height of the seedling tray 202, and the lifting platform is also provided with through holes running through the upper and lower surfaces thereof and a pressing piece (not shown) for fixing the seedling tray 202, one end of the seedling tray 202 pressing piece is connected to the lifting platform, and the other end is pressed against the seedling tray 202 after the seedling tray 202 is placed. Each seedling tray 202 is fixed to the lifting platform by at least 2 pressing pieces arranged opposite to each other, so that the cultivation module 2 can be stably fixed on the lifting platform to avoid sliding during the lifting process.

[0039] Please refer to Figure 3. Each seedling tray 202 includes at least 9 cultivation holes. The common edges between adjacent cultivation holes are provided with through holes 11 running through the upper and lower surfaces thereof. This structural design can facilitate the lifting and lowering of the cultivation module 2. The fact that the cultivation holes are not connected can prevent the roots in adjacent cultivation holes from being mixed, which facilitates the subsequent transplanting of plants.

[0040] The dosing device 5 is filled with a slow-release agent for inhibiting unicellular algae. The preparation method of the slow-release agent is as follows: 500g of dried broadleaf cattail, 300g of Vallisneria lappa, and 200g of Myriophyllum paniculate are leached in 5L of pure water for 24h, concentrated to 100ml, and then mixed with gum arabic and calcium carbonate in a volume ratio of 2:1:6 to granulate to obtain a slow-release agent with a particle size of 1-3mm. The average particle size can be 1mm, 1.5mm, 2mm, 2.5mm and 3mm.

[0041] Please refer to Figure 1. The water flow propulsion device 4 includes at least 6 propellers installed on a group of inner walls opposite to each other in the cultivation tank 1. The propellers are driven by a motor. At least 3 propellers are installed on each inner wall. The distance between the axes of the two propellers located on the outside of the same inner wall and the inner wall on the same side is 20-30 cm, specifically 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, and a dosing device 5 is connected in front of at least one propeller. The above-mentioned propellers are arranged at high and low positions to prevent the propellers from being too close to cause relative water flow and affect the stirring effect.

[0042] Specifically, there are 6 propellers, and 3 propellers are connected to each inner wall. The rotating shaft fixed to the propeller in the middle is connected to a dosing device 5. The dosing device 5 includes a dosing box. The dosing box is provided with a drug outlet hole. The diameter of the drug outlet hole is smaller than the diameter of the drug. The dosing box is connected to a drug inlet pipe. The drug inlet pipe is connected to the dosing box through a thread or can be an integrated structure. After sowing seeds in the culture medium, a slow-release drug is added to the dosing device 5. The dosing device 5 is installed in front of the propeller to quickly disperse the drug in the water body, thereby further improving the inhibitory effect of the drug on unicellular algae and filamentous algae.

[0043] The fill light module 3 is height-adjustable. This structural design allows the height of the fill light module 3 to be adjusted according to actual weather conditions and the light requirements of plants at different growth stages. A thermal insulation layer 12 is provided on the exterior of the cultivation pool 1. When the cultivation pool 1 is placed outdoors, the structural design of the thermal insulation layer 12 can insulate the water in the cultivation pool 1 during winter and early spring, reducing energy consumption and preventing plant burns from high temperatures in summer, thereby improving plant survival rate. Specifically, the thermal insulation layer 12 is made of one or more of extruded polystyrene foam (extruded board), molded polystyrene foam (foam board), spray-on rigid polyurethane foam, and rigid polyurethane foam insulation board.
