Description

Technical Field

[0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a device for soilless cultivation and growth promotion of medicinal plants. Background Art

[0002] In traditional agriculture, land has always been the core element of agricultural production, providing plants with the basic conditions for growth. However, the frequent use of chemical fertilizers has long led to the deterioration of soil structure and the occurrence of compaction, which not only affects the growth of crops, but also causes a large loss of nutrients in the soil. The development of soilless cultivation technology, especially the emergence of pipeline hydroponic devices, has brought revolutionary changes to agriculture. Pipeline hydroponic soilless cultivation devices circulate nutrient solution in pipes to provide necessary nutrients and oxygen to plant roots. This method not only improves crop yield and quality, but also greatly reduces land use and water consumption. Although soilless cultivation technology brings many advantages, the existing pipeline hydroponic soilless cultivation devices are not efficient in space utilization due to their large size, especially in urban environments with tight land resources.

[0003] There are some soilless cultivation devices that hope to solve this problem. Patent publication number CN206909356U discloses a flat-frame pipeline soilless cultivation device for medicinal plants. The device adopts flat-frame pipeline planting, and each row of pipelines has several planting holes. The entire nutrient solution device has a good circulation system and will not cause water and fertilizer waste and environmental pollution.

[0004] However, there are certain limitations when using this device. First, although this device increases the planting density of hydroponic plants, the space utilization rate in the vertical direction is not high; secondly, this device cannot adjust the water level of hydroponics, and cannot adapt to the water level required by medicinal plants of different types and different growth periods; in addition, when planting plants, although this device can ensure the continuous flow of water in the pipe to reduce the possibility of water rot, the aquatic rhizomes of plants cultivated using this device are always soaked below the water surface. Plants planted under this planting method need to be observed and adjusted at all times. The distance of the plant roots submerged in the water surface, otherwise, if the fleshy part or the stem neck of the plant is soaked in water for a long time, root rot and decay are very likely to occur, and the device itself cannot observe and adjust the water level of the pipe.

[0005] Therefore, there is a need for a soilless cultivation and growth promotion device for medicinal plants, which can enable plants to be planted in three dimensions and make full use of vertical space; in addition, the device uses the principle of siphon and sets up tidal pipes, so that the water level of the plant roots changes up and down periodically, thereby avoiding the plant roots being always submerged in water; in addition, the device is provided with a water level regulating mechanism, which can change the water level of each layer of hydroponic storage position according to needs, so that a set of devices can simultaneously adapt to the water level required for hydroponic cultivation of different medicinal plants.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Example 1

[0032] The invention discloses a soilless cultivation and growth promotion device for medicinal plants, referring to Figures 1 to 7The core of the device consists of three parts: a hydroponic tank 1, a water supply system 2, and a filter tank 3, forming a complete hydroponic environment. The hydroponic tanks 1 in the device can be installed in an array vertically according to the size of the environment and actual needs to achieve effective use of space. The hydroponic tank 1 at the bottom is connected to the water supply system 2, so that the circulated water flows back to the water tank 201, ensuring a stable supply of water and nutrients; each hydroponic tank 1 includes an external connecting pipe 101, a planting basket 102, a planting elbow 103, a downpipe 104, a siphon 105, a regulating pipe 106, a water storage pipe 107, and a two-part upper water pipe 108. The device realizes automatic adjustment of the water level through the siphon principle. The water storage pipe 107 is the central part of the system, and the siphon 105 and the regulating pipe 106 for maintaining the water level are fixedly set inside it. The two-way water supply pipe 108 is composed of a water receiving tray 1011, a three-way pipe 1010 and a water supply capillary 109. The water receiving tray 1011 can reduce the splashing of water.

[0033] Example 2

[0034] In the present embodiment, the medicinal plant planting soilless culture and growth promotion device fixes the plants through the planting basket 102, ensures the fixation and support of the plant roots, and enables the plants to grow in the best posture. The design of the planting elbow 103 takes into account the growth characteristics of the plant roots and the absorption requirements for water and nutrients. The structure and pore size of the planting basket 102 are designed to not only fix the plants, but also allow water and nutrient solution to flow smoothly to the roots of the plants. It ensures that the plant roots can stretch freely in sufficient space, while avoiding the problems of root crowding and uneven nutrition that may occur in traditional soil cultivation. In addition, the detachable design of the planting basket 102 also helps to keep the hydroponic tank 1 clean and facilitates the observation of water flow in the device.

[0035] Example 3

[0036] In this embodiment, the bottom end of the external connection pipe 101 of the device is designed with a connection interface, which allows each hydroponic tank 1 layer to be flexibly disassembled and reassembled to meet the needs of planting of different scales or for regular cleaning and maintenance. In addition, the design of the connection interface takes into account the sealing performance to ensure that there will be no water leakage during the operation of the hydroponic system, while also reducing the unnecessary loss of nutrients.

[0037] Example 4

[0038] In this embodiment, the water supply system 2 is responsible for providing a stable and sufficient water source for the entire hydroponic system. The water supply system 2 is composed of several key components: a large water tank 201, a high-efficiency water pump 202, and a suction pipe 203 connecting the water pump 202 and the upper water head 204. The water pump 202 is the core of the water supply system 2, which is responsible for pumping the water in the water tank 201 to the upper water head 204 through the suction pipe 203. The water pump 202 is installed inside the water tank 201, so that the water pump 202 can directly draw water from the water tank 201. The design of the suction pipe 203 takes into account durability and corrosion resistance to ensure long-term and stable use. One end of it is fixedly connected to the water pump 202, and the other end is fixedly connected to the upper water head 204, forming a closed circulation system. The upper water head 204, as the end point of the suction pipe 203, is responsible for conveying the water flow generated by the water pump 202 to the filter tank 3. Prevent the overflow of the water flow. The function of the water tank 201 in the water supply system 2 is to store and supply water. It has sufficient capacity to meet the water needs of plants at different growth stages. The water tank 201 is also provided with a water replenishment port 205. This detailed design allows water and nutrient solution to be easily replenished into the water tank 201 when the water level in the water tank 201 drops.

[0039] Example 5

[0040] In this embodiment, the filter chamber 3 is a key link to ensure the cleanliness of water flow and nutrient solution. A filter cotton 301 is installed inside the filter chamber 3. The porous structure of the filter cotton 301 can effectively capture and intercept tiny particles, impurities and harmful microorganisms in the water. The use of the filter cotton 301 not only helps to improve the quality of the plant growth environment, but also reduces the occurrence of plant diseases and improves the yield and quality of medicinal plants.

[0041] Example 6

[0042] In this embodiment, the pipes in the device are made of opaque material. This choice is mainly to prevent sunlight from directly shining on the inner wall of the pipe, because direct sunlight will provide the necessary lighting conditions for the growth of green algae in the pipe. The growth of green algae will not only affect the transparency of the nutrient solution, but also consume the oxygen in the water, thereby negatively affecting the growth environment of the plant roots.

[0043] The use of opaque pipes effectively blocks sunlight from penetrating, thereby inhibiting the growth of green algae in the pipes and keeping the nutrient solution clean and the water quality stable. This design not only helps reduce the maintenance requirements of the system and the workload of frequent pipe cleaning due to green algae growth, but also ensures that medicinal plants can grow in a healthier and more stable environment.

[0044] In addition, the opaque pipes also have a heat-insulating effect, which can reduce the water temperature caused by direct sunlight, thereby avoiding the damage that excessive water temperature may cause to plant roots. This is particularly important in the hot summer, because excessive water temperature may affect the growth rate and yield of plants.

[0045] The working principle and process of this device are as follows:

[0046] After the device is assembled, the highest point of the water level in the water storage pipe 107 is set by adjusting the height of the downpipe 104 in the siphon 105. Sufficient water is added to the water tank 201, and the water pump 202 is started, and the entire device starts to work; after the water pump 202 draws water to the upper water head 204, the water flows into the filter chamber 3, and the water flows into the water receiving tray 1011 of the device after being filtered in the filter chamber 3; after the water flow is collected by the water receiving tray 1011, it flows into the water storage pipe 107 of the device through the three-way pipe 1010 and the upper water capillary 109, and accumulates in the water storage pipe 107. As the water flow continues to increase, the water level in the water storage pipe 107 will slowly rise until the water level overflows the top of the downpipe 104. This is also the highest point of the water level in the water tank 201. Due to the presence of the siphon 105, there is no air in the siphon 105. Under the siphon effect, the water will flow out of the downpipe 104 and flow into the water receiving tray 1011 of the next hydroponic tank 1. When the water level drops below the siphon 105, air will enter the siphon 105, and the siphon effect will stop. This is also the lowest point of the water level in the water tank 201. The siphon movement is repeated, and the water flowing out of the downpipe 104 of the bottom hydroponic tank 1 returns to the water tank 201. In this process, the power and flow of the water pump 202 cannot be too large. It is necessary to ensure that the flow of the water pump 202 is less than the downpipe 104 water flow, otherwise the siphon movement of the device will not stop, and the tidal effect cannot be produced.

[0047] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only the specific implementation methods described.
