The vertical space of the phyllostachys edulis forest is effectively utilized, the defects of traditional under-forest planting are overcome, and the multiple purposes of saving water and fertilizer, protecting ecology and improving economic benefits are achieved.

Description

Technical Field

[0001] This invention relates to the field of ecological agricultural planting technology, specifically to a vertical hydroponic and aquaponics integrated planting system and method for living bamboo forests. Background Technology

[0002] The mountainous terrain of Lishui is characterized by "nine parts mountains, half part water, and half part farmland," and it boasts abundant bamboo forest resources, which are an important foundation for developing the rural economy. However, the traditional understory planting model has obvious drawbacks: First, planting medicinal herbs on the ground easily damages the original vegetation cover, exacerbates soil erosion, and threatens the ecological balance of the mountainous area; second, ground crops are often attacked by wild animals, resulting in unstable yields; and third, frequent field management such as weeding, irrigation, and fertilization is required, leading to high labor costs and limited economic benefits.

[0003] Current technologies lack planting schemes that can effectively utilize the three-dimensional spatial resources of living bamboo and construct an ecological cycle system. Therefore, there is an urgent need for an innovative planting model to achieve synergistic development of ecological protection and economic benefits. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems in the prior art and provide a vertical hydroponic and aquaponics integrated planting system and method for living bamboo forests.

[0005] This invention provides a vertical hydroponic and aquaponics integrated planting system and method for living bamboo forests. Based on healthy, living bamboo, the system includes a hydroponic circulation system comprising a supply system at the top of the bamboo forest area and a return system at the bottom. The supply system is connected to the top of the living bamboo, and the return system is connected to the bottom. The aquaponics circulation system includes at least one fishpond and a water pump. The fishpond is connected to the supply system via the water pump to transport wastewater from the fishpond to the supply system as nutrient solution. The return system is connected to the fishpond to return purified water to the fishpond. Planting holes for medicinal plants are provided on the nodes of the living bamboo, and through holes for nutrient solution flow are provided on adjacent nodes. The supply system delivers nutrient solution to the planting holes, and the return system collects unabsorbed nutrient solution.

[0006] Preferably, the planting hole is an oblique hole with a diameter of 1cm-2.5cm and an inclination angle of 15°-30°; adjacent planting holes are alternately distributed on the left and right.

[0007] Preferably, the adjacent planting holes are distributed in a spiral pattern with a pitch of 15cm-20cm.

[0008] Preferably, the diameter of the through hole is 0.5cm-1cm, and the through holes form a longitudinally connected nutrient solution channel inside the bamboo node, while the unconnected part forms a water storage structure.

[0009] Preferably, the nutrient solution supply system includes a high-level pool, a nutrient solution supply side pipe, and a branch pipe connected to the top of each living bamboo plant. One end of the nutrient solution supply side pipe is connected to the high-level pool, and a plurality of the branch pipes are arranged in an array along the length of the nutrient solution supply side pipe. The nutrient solution supply side pipe is equipped with a solenoid valve, and the branch pipes inject nutrient solution into the planting hole by drip irrigation or micro-spraying.

[0010] Preferably, the reflux system includes a U-shaped reflux trough disposed at the planting hole at the bottom of the live bamboo, a plurality of reflux pipes and a reflux side pipe, wherein the plurality of reflux pipes are all connected to the reflux side pipe, and the other end of the reflux side pipe is placed in the fish pond.

[0011] Preferably, the fish pond is circular or rectangular with walls enclosed by stainless steel plates. The water pump is located outside the fish pond, with its inlet connected to the fish pond and its outlet connected to a return pipe. One end of the return pipe is placed inside the elevated tank.

[0012] A preferred method for vertical hydroponics of living bamboo forests combined with aquaponics includes the following steps: In the selected bamboo forest, the planting holes and the through holes are made on the living bamboo to construct the fish pond, and the liquid supply system, the return system and the water pump are installed and connected. Fish are raised in the fish pond, and the water pump is started to transport the wastewater from the fish pond to the liquid supply system; Seedlings of medicinal plants suitable for epiphytic growth are planted in the planting holes of the living bamboo. The hydroponic circulation system and the aquaponics circulation system have started operating, and water quality and nutrient parameters are monitored and adjusted regularly.

[0013] Compared with the prior art, the beneficial effects of the present invention are: Through innovative vertical hydroponics, living bamboo is transformed into a growth carrier for medicinal plants, greatly improving the three-dimensional utilization efficiency of bamboo forests per unit area and realizing a leap from traditional planar planting to spatial resource development. The organic combination of the hydroponic circulation system and the aquaponics circulation system constructs a highly efficient ecological cycle: the nutrient-rich wastewater from the fishpond is used as a nutrient solution to supply the plants, and the purified water absorbed by the plants flows back to the fishpond, forming a closed-loop production model with zero waste discharge. This not only effectively overcomes the drawbacks of traditional understory planting, such as damage to vegetation, easy soil erosion, and high management costs, but also significantly improves the utilization efficiency of water resources and nutrients, providing a new solution for mountain ecological agriculture that is resource-saving, environmentally friendly, and has outstanding economic benefits, achieving synergistic effects between ecological protection and industrial development.

[0020] This invention provides a vertical hydroponic and aquaponics integrated planting system for living bamboo 101 forests, such as... Figures 1-2 As shown, the system is based on healthy, living bamboo 101 and includes a hydroponic circulation system 2, comprising a liquid supply system 21 located at the top of the bamboo grove area and a return system 22 located at the bottom of the bamboo grove area. The liquid supply system 21 is connected to the top of the living bamboo 101, and the return system 22 is connected to the bottom of the living bamboo 101. An aquaponics circulation system 3 includes at least one fish pond 31 and a water pump 32. The fish pond 31 is connected to the liquid supply system 21 via the water pump 32. The system 21 is used to transport wastewater from the fish pond 31 to the nutrient solution supply system 21. The return system 22 is connected to the fish pond 31 and is used to return the purified water to the fish pond 31. The bamboo nodes of the living bamboo 101 are provided with planting holes 102 for planting medicinal plants, and the adjacent bamboo nodes are provided with through holes 103 for the flow of nutrient solution. The nutrient solution supply system 21 is used to deliver nutrient solution to the planting holes 102, and the return system 22 is used to collect the nutrient solution that has not been absorbed.

[0021] In this embodiment, the innovative vertical hydroponic device 1 transforms living bamboo 101 into a growth carrier for medicinal plants, greatly improving the three-dimensional utilization efficiency of bamboo forests per unit area and realizing a leap from traditional planar planting to spatial resource development. The organic combination of the hydroponic circulation system 2 and the aquaponics circulation system 3 constructs a highly efficient ecological cycle: the nutrient-rich wastewater from the fish pond 31 is used as a nutrient solution to supply the plants, and the purified water absorbed by the plants flows back to the fish pond, forming a closed-loop production mode with zero waste discharge. This not only effectively overcomes the drawbacks of traditional understory planting, such as damage to vegetation, easy soil erosion, and high management costs, but also significantly improves the utilization efficiency of water resources and nutrients, providing a new solution for mountain ecological agriculture that is resource-saving, environmentally friendly, and economically beneficial, achieving synergistic effects between ecological protection and industrial development. In this embodiment, the nutrient supply system 21 is located on one side of the planting hole 102 at the very top of the living bamboo.

[0022] Preferred, such as Figures 1-3 As shown, the planting hole 102 is an oblique hole with a diameter of 1cm-2.5cm and an inclination angle of 15°~30°; adjacent planting holes 102 are distributed alternately on the left and right.

[0023] In this embodiment, the slanted holes with a diameter of 1cm-2.5cm not only securely accommodate the roots of the medicinal plant seedlings, but their angle also effectively prevents the rapid loss of nutrient solution, ensuring a continuous supply of water and nutrients to the roots. The alternating left-right distribution avoids excessive weakening of the bamboo structure by opening holes on the same vertical line, while allowing each plant to receive light evenly, reducing mutual shading between plants and promoting balanced plant growth.

[0024] Preferred, such as Figures 1-3 As shown, adjacent planting holes 102 are spirally distributed with a pitch of 15cm-20cm.

[0025] In this embodiment, the spatial layout is optimized to the extreme. Compared to a simple vertical arrangement, the spiral distribution significantly increases the number of planting holes 102 on a single bamboo plant without increasing the density of openings on the bamboo surface, thereby greatly improving the planting capacity of medicinal plants. This distribution method allows the nutrient solution to more evenly irrigate the plant roots in each planting hole 102 as it flows down the bamboo surface, avoiding localized over-wetting or drought, creating a more stable and ideal growth microenvironment for the plants, and further improving the overall system's output efficiency.

[0026] Preferred, such as Figures 1-3 As shown, the diameter of the through hole 103 is 0.5cm-1cm. Several through holes 103 make the interior of the bamboo joint form a longitudinally connected nutrient solution channel, while the unconnected part forms a water storage structure.

[0027] In this embodiment, the through holes 103 with a diameter of 0.5cm-1cm form longitudinally connected nutrient solution channels on the adjacent bamboo nodes, ensuring that the nutrient solution can flow smoothly from top to bottom and achieve effective irrigation of the entire bamboo planting unit; at the same time, the unconnected parts naturally form a water storage structure, like a miniature reservoir, which can temporarily store and buffer the flowing nutrient solution, which can not only cope with the short-term fluctuations of the nutrient supply system 21, but also prolong the contact time between the roots and the nutrient solution, improve the absorption efficiency of water and nutrients, and enhance the stability and reliability of the system.

[0028] Preferred, such as Figures 1-2As shown, the nutrient solution supply system 21 includes a high-level pool 211, a nutrient solution supply side pipe 212, and a branch pipe 213 connected to the top of each living bamboo 101. One end of the nutrient solution supply side pipe 212 is connected to the high-level pool 211, and several branch pipes 213 are arranged in an array along the length of the nutrient solution supply side pipe 212. The nutrient solution supply side pipe 212 is equipped with a solenoid valve, and the branch pipes 213 inject nutrient solution into the planting hole 102 by drip irrigation or micro-spraying.

[0029] In this embodiment, by utilizing gravitational potential energy through the elevated pool 211, combined with the supply side pipe 212 equipped with a solenoid valve and the branch pipe 213, the delivery volume and timing of the nutrient solution can be precisely controlled. The branch pipe 213 uses drip irrigation or micro-sprinkler to directly inject the nutrient solution into the planting hole 102, greatly reducing liquid evaporation and drift loss, and achieving efficient utilization of water resources. The solenoid valve facilitates zoned and time-based management, allowing for flexible adjustment of irrigation strategies according to different plant growth stages or environmental conditions, reducing the intensity of manual management, and improving the system's intelligence level and operational efficiency.

[0030] Preferred, such as Figures 1-2 As shown, the reflux system 22 includes a U-shaped reflux trough 221 set at the planting hole 102 at the bottom of the live bamboo 101, several reflux pipes 222 and reflux side pipes 223. The several reflux pipes 222 are all connected to the reflux side pipes 223, and one end of the reflux side pipes 223 is placed in the fish pond 31.

[0031] In this embodiment, efficient and clean nutrient solution recovery is achieved. The U-shaped return channel 221, located at the bottom of the living bamboo 101, effectively collects the nutrient solution that is not fully absorbed and flows down from the bamboo nodes above. This nutrient solution is then gathered through a network of return pipes and return side pipes 223. The U-shaped structure acts as a water seal, effectively preventing backflow of impurities and the emission of odors, thus maintaining a clean bamboo forest environment. The entire return system ensures that the nutrient solution, purified by plant roots, is completely returned to the fish pond 31. This system ensures that the nutrient solution, purified by plant roots, is completely returned to the fish pond 31, completing a crucial link in the aquaponics cycle. It provides clean water for the fish and achieves nutrient recycling, demonstrating the ecological cycle value of the system.

[0032] Preferred, such as Figures 1-2 As shown, the fish pond 31 is circular or rectangular with stainless steel plates surrounding the walls. The water pump 32 is located outside the fish pond 31. The water inlet of the water pump 32 is connected to the fish pond 31, and the water outlet is connected to a return pipe 33. The other end of the return pipe 33 is placed inside the high-level pool 211.

[0033] In this embodiment, the reliability of the circulating power and the integrity of the system are ensured. The fish pond 31 is enclosed by stainless steel plates, which is sturdy, durable, and easy to maintain and clean. The external design of the water pump 32 facilitates maintenance. It lifts the wastewater from the fish pond 31 to the elevated pool 211 through the return pipe 33, completing the water transport from low to high, and providing the initial power for the gravity-fed irrigation of the entire system. This design allows the fish pond wastewater to be effectively recycled and reused as a resource in the production cycle, strengthening the closed-loop characteristics of the aquaponics system and ensuring the continuous and stable operation of the entire integrated planting system.

[0034] The method of using the living bamboo 101 forest vertical hydroponics and aquaponics integrated planting system of the present invention is as follows: In the selected bamboo forest, healthy living bamboo 101 is selected, and planting holes 102 with specific angles and spacings are drilled on the bamboo nodes according to the design requirements. Through holes 103 are drilled on the partitions of adjacent bamboo nodes to connect the nutrient solution channels. At the same time, a fish pond 31 is constructed, and the nutrient solution supply system 21 and the return system 22 are installed and connected to ensure that the water pump 32 can pump the water from the fish pond 31 into the high-level pool 211.

[0035] An appropriate amount of fish are stocked in fishpond 31 for aquaculture, and then water pump 32 is started. Water pump 32 transports nutrient-rich fishpond wastewater to elevated tank 211. Under gravity, the nutrient solution is distributed through the supply system 21 to the branch pipes 213 at the top of each bamboo plant, entering the bamboo through drip irrigation or micro-spraying, flowing from top to bottom through each planting hole 102, nourishing the medicinal plant seedlings. Unabsorbed liquid is eventually collected by the bottom return system 22.

[0036] Once the system enters the continuous operation phase, it is necessary to regularly monitor the water quality parameters of the fish pond 31 and the nutrient solution, as well as the growth status of the medicinal plants. Based on the monitoring results, adjust the feeding amount, the operating time of the water pump 32, or supplement necessary nutrients in a timely manner to maintain the dynamic balance of aquaponics and hydroponic circulation, ensuring the healthy growth of both fish and medicinal plants, thereby achieving long-term stable and efficient output of ecological planting.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
