DETAILED DESCRIPTION

[0024] With the acceleration of urbanization and the improvement of people's living standards, the demand for fresh and healthy vegetables is growing. The traditional soil planting method is limited by land resources and environmental conditions, and it is difficult to meet the needs of modern urbanites for convenient, efficient and green vegetable planting. Therefore, indoor vegetable planting hydroponic devices came into being, and gradually became a new trend in the development of urban agriculture with its unique advantages.

[0025] Indoor vegetable hydroponic device is a soilless cultivation method that uses nutrient solution instead of soil to provide plants with necessary water and nutrients. Its basic principle is to place the plant roots in a circulation system containing an appropriate amount of nutrient solution so that the plants can absorb the required nutrients and oxygen to achieve normal growth. In this process, the nutrient solution circulation system and environmental control system play a key role.

[0026] Nutrient solution circulation system: This system consists of a nutrient solution storage tank, a circulation pump, pipes, and a cultivation bed. Driven by the circulation pump, the nutrient solution is transported to the cultivation bed through the pipe to provide nutrients for the plant roots. At the same time, the nutrient solution is filtered and disinfected during the circulation process to maintain its cleanliness and stability.

[0027] Environmental control system: This system includes the regulation of environmental factors such as light, temperature, humidity and ventilation. By adjusting the light intensity and light time, the photosynthesis needs of plants at different growth stages can be met; by adjusting the temperature and humidity, a suitable plant growth environment can be created; through ventilation, the indoor air can be kept fresh and the occurrence of pests and diseases can be reduced.

[0028] Compared with traditional soil planting methods, indoor vegetable planting hydroponic devices have many advantages and characteristics, mainly including the following aspects:

[0029] Saving land resources: Hydroponic devices can be used to grow vegetables indoors or in limited spaces without occupying a large amount of land resources. This is of great significance for urban areas where land resources are scarce.

[0030] Improve production efficiency: The hydroponic device can optimize the growth process of plants and improve the yield and quality of vegetables by precisely controlling the composition of the nutrient solution and environmental conditions. At the same time, the recycling of the nutrient solution reduces the waste of water resources.

[0031] Reduce pests and diseases: The plant roots in the hydroponic device are in a relatively closed environment, which reduces the chance of contact with the outside environment, thereby reducing the chance of pests and diseases. In addition, the risk of pests and diseases can be further reduced by regularly replacing and disinfecting the nutrient solution.

[0032] Easy to manage: The hydroponic device uses an automated control system to regulate environmental factors and manage the circulation of nutrient solution, which greatly simplifies the management difficulty of the planting process. Growers only need to regularly check and adjust system parameters to achieve continuous production of vegetables.

[0033] Green and environmentally friendly: The hydroponic device does not use chemical fertilizers, pesticides and other chemicals, reducing environmental pollution and ecological damage. At the same time, due to the clean and controllable environment for vegetable growth, the vegetables produced are greener, healthier and safer.

[0034] According to different structural characteristics and application scenarios, indoor vegetable growing hydroponic devices can be divided into many types. The following are some common types and their characteristics:

[0035] Column system hydroponic device

[0036] The column system hydroponic device, also known as the tower system hydroponic device, is a vertical planting method. The device usually consists of columns, planting holes, buckets, and a nutrient solution circulation system. The planting holes are evenly distributed on the columns, and growers can transplant vegetable seedlings into the planting holes. The bucket is filled with nutrient solution, which is transported to the planting holes of the columns through a circulation pump to provide nutrients for the plant roots. The column system hydroponic device has the advantages of small footprint, high space utilization, and easy management.

[0037] NFT system hydroponic device

[0038] The NFT system hydroponic device is a relatively advanced soilless cultivation method, and its full name is Nutrient Film Technique. The system consists of a seedbed, a nutrient solution tank, a circulation pump and pipes. A thin film is laid on the seedbed, and the nutrient solution forms a thin liquid film on the film. The plant roots directly contact the liquid film to absorb nutrients. The NFT system hydroponic device has the advantages of easy cleaning, high nutrient utilization rate and fast growth rate. However, it should be noted that the NFT system has high requirements for the management of water quality and nutrient solution, and the nutrient solution needs to be replaced and disinfected regularly.

[0039] Deep flow hydroponic device

[0040] The deep liquid flow hydroponic device is a soilless cultivation method that places the plant roots in a deeper layer of nutrient solution. The device consists of a storage tank, a cultivation trough, a planting plate and a circulation system. The storage tank is filled with a large amount of nutrient solution, which is transported to the cultivation trough by a circulation pump. The plant roots grow in the nutrient solution in the cultivation trough and continuously obtain fresh nutrient solution through the circulation system. The deep liquid flow hydroponic device has the advantages of good stability, sufficient nutrient supply, and controllable growth environment. However, it should be noted that the device has high requirements for the management and maintenance of the nutrient solution, and the composition and concentration of the nutrient solution need to be regularly tested and adjusted.

[0041] Home balcony hydroponic device

[0042] The family balcony hydroponic device is a small vegetable planting device suitable for the home environment. The device is usually composed of a nutrient solution storage tank, a culture cylinder, a spray device and a control system. The grower can put the vegetable seeds or seedlings into the culture cylinder and spray the nutrient solution onto the plant roots through the spray device. The family balcony hydroponic device has the advantages of simple operation, small footprint and convenient management. At the same time, the device can also be customized and adjusted according to the home environment to meet the needs of different families.

[0043] The successful application of indoor vegetable hydroponic devices is inseparable from the support of a series of key technologies. The following are some key technologies and their importance:

[0044] Nutrient solution preparation technology

[0045] Nutrient solution is the main way for plants to obtain nutrients in hydroponic devices. Therefore, the preparation technology of nutrient solution has an important impact on plant growth and yield. The preparation of nutrient solution needs to be accurately calculated and adjusted according to the growth needs and growth environment of the plants. At the same time, it is also necessary to pay attention to the monitoring and adjustment of parameters such as pH value and EC value of the nutrient solution to ensure the stability and effectiveness of the nutrient solution.

[0046] Environmental Control Technology

[0047] Environmental control technology is an indispensable part of indoor vegetable hydroponic devices. By adjusting environmental factors such as light, temperature, humidity and ventilation, a suitable environment for plant growth can be created. The adjustment of light intensity and light time can meet the photosynthesis needs of plants at different growth stages; the adjustment of temperature and humidity can maintain the suitable temperature range for plant growth; ventilation can keep the indoor air fresh and reduce the occurrence of pests and diseases.

[0048] Circulation system design and optimization

[0049] The circulation system is a key part of the hydroponic device to realize the circulation and renewal of nutrient solution. The design of the circulation system needs to consider the flow rate, pressure, flow rate and other parameters of the nutrient solution to ensure that the nutrient solution can be evenly and stably delivered to the plant root system. At the same time, the maintenance and cleaning of the circulation system also need to be considered to avoid system failures caused by blockage or contamination. Optimizing the circulation system can improve the utilization rate of the nutrient solution and the stability of the system, thereby improving the yield and quality of vegetables.

[0050] Plant growth and development regulation technology

[0051] Plant growth and development regulation technology is an important means to achieve high yield and high quality of vegetables in hydroponic devices. By adjusting parameters such as the plant's growth cycle, growth rate and growth morphology, the plant's growth process can be optimized and the yield and quality of vegetables can be improved. This technology includes seed treatment, seedling technology, planting technology, pruning and branch removal, etc. By comprehensively applying these technologies, continuous production and efficient utilization of vegetables can be achieved.

[0052] With the advancement of science and technology and people's pursuit of healthy life, indoor vegetable planting hydroponic device technology will show the following development trends:

At the same time, precise regulation can be carried out according to the growth needs and growth environment of the plants to achieve customized planting. This will enable growers to flexibly adjust planting strategies according to the growth characteristics and market demand of different vegetables, thereby improving the quality and market competitiveness of vegetables.

[0054] Development of energy-saving and environmental protection technologies: While pursuing efficient production, energy conservation and environmental protection will also become an important development direction for indoor vegetable hydroponic device technology. For example, by developing more efficient LED light sources and light formula technology, energy consumption can be reduced and photosynthesis efficiency can be improved; by optimizing the nutrient solution circulation system and recycling technology, water resource waste can be reduced; by adopting green control technologies such as biological control and physical control, the use of chemical pesticides can be reduced and environmental pollution can be reduced.

[0055] Multifunctional integration and modular design: In order to meet different scenarios and needs, future indoor vegetable hydroponic devices will pay more attention to multifunctional integration and modular design. By integrating multiple functions such as environmental monitoring, nutrient supply, and pest control, comprehensive management and optimization of the vegetable growth process can be achieved. At the same time, modular design will make the device more flexible and variable, and it can be freely combined and expanded according to factors such as planting space and planting scale.

[0056] Application of new materials and technologies: With the continuous advancement of materials science and technology, more new materials will be used in indoor vegetable hydroponic devices in the future. For example, materials with excellent thermal conductivity and antibacterial properties can be used to make cultivation beds and nutrient solution pipes to improve the stability and durability of the system; smart materials and nanotechnology can be used to develop more accurate nutrient solution delivery systems and environmental control systems.

[0057] Promotion of community sharing and family planting models: As people pay more and more attention to healthy eating and green living, community sharing and family planting models will become important application areas for indoor vegetable planting hydroponic devices in the future. By establishing community-shared hydroponic vegetable planting bases or providing small hydroponic devices for home use, more people can be encouraged to participate in vegetable planting, enjoy the fun of planting and obtain fresh and healthy vegetables.

[0058] As an efficient, environmentally friendly and convenient way to produce vegetables, indoor vegetable hydroponic devices are playing an increasingly important role in modern urban agriculture. By continuously improving and optimizing key technologies and introducing advanced technologies such as intelligence and automation, indoor vegetable hydroponic devices will achieve a more efficient, energy-saving and environmentally friendly production model in the future. At the same time, with the application of new materials and new technologies and the promotion of community sharing and family planting models, the application scope of indoor vegetable hydroponic devices will be further expanded, providing more people with healthy and green vegetable choices.
