Description

Technical Field

[0001] The utility model relates to the technical field of soilless cultivation in greenhouses, and more specifically, to a root zone temperature control heating device for substrate trough cultivation. Background Art

[0002] Sunlight greenhouses are the main facility types for off-season production of fruits and vegetables in winter in northern China. The relatively low outdoor temperature in winter in sunlight greenhouses will affect the indoor air temperature, and sub-low temperatures below 10°C often occur at night. For substrate cultivation, since the bulk density of the substrate is lighter than that of soil, the root zone temperature in trough cultivation is much lower than that of traditional soil. Prolonged sub-low temperatures at night will cause the root temperature conditions not to meet the environmental requirements for the normal physiological activities of plants, ultimately leading to a reduction in production.

[0003] Traditional greenhouse air heating cannot solve the problem of low root zone temperature. Heating the root zone of plants is more conducive to the growth of plants in the greenhouse. Especially under the condition of trough cultivation, the plant roots can be fully extended by controlling the appropriate root zone temperature within a limited area, which plays a very important role in plant growth, facilitating the absorption of nutrients and water by plants and the development of root cells; compared with traditional greenhouse air heating, heating the root zone of plants can better meet the temperature requirements for the growth and development of plants; currently, common methods for root zone heating include carbon crystal panel heating for potted plants, underground heat storage systems, solar heating of water and soil, etc. These methods have disadvantages such as complex structural settings, large cost investment, and being overly affected by objective weather conditions. There are certain limitations in using these technologies for the production of fruit and vegetable crops in sunlight greenhouses.

[0004] Therefore, how to provide a root zone temperature control heating device with a simple structure that can regulate the temperature of the root environment, effectively improve the root zone temperature environment, and ensure the normal growth of plants is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0005] In view of this, the utility model provides a root zone temperature control heating device for substrate trough cultivation, aiming to solve the above technical problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A root zone temperature control heating device for substrate trough cultivation includes a cultivation trough and a cultivation substrate bag placed inside the cultivation trough, and further includes a heating component and a temperature control unit. The heating component is arranged inside the cultivation substrate bag, and the temperature control unit is electrically connected to the heating component.

[0008] Through the above technical solution, a substrate trough-type cultivation root zone temperature control heating device provided by the utility model has coconut coir as the substrate in the cultivation substrate bag, and plants are planted inside it. The heating component is arranged in the substrate to heat the roots of the plants planted in the cultivation substrate bag, and the temperature control unit detects the temperature of the plant roots. According to the detected root temperature, the heating component is controlled to heat to meet the temperature requirements of the plant roots. The structure of the utility model is simple, can regulate the temperature of the root environment, effectively improve the root zone temperature environment, and ensure the normal growth of plants.

[0009] Preferably, in the above-mentioned substrate trough-type cultivation root zone temperature control heating device, the heating component is located in the middle of the cultivation substrate bag. Placing the electric heating wire at the geometric center of the cultivation substrate bag can ensure that the heat diffuses evenly from the center to the surrounding, so as to heat the entire substrate bag more evenly; it can also arrange the heating component at a suitable position according to actual needs as long as it can meet the heating requirements of the roots. At the same time, it is necessary to ensure that there is a certain safety distance between the electric heating wire and the wall surface of the cultivation substrate bag to prevent overheating or damage to the substrate bag.

[0010] Preferably, in the above-mentioned substrate trough-type cultivation root zone temperature control heating device, the heating component is an electric heating wire, and the number of the electric heating wires is multiple. The multiple electric heating wires are evenly distributed in the middle of the cultivation substrate bag, and the multiple electric heating wires are connected in parallel. The parallel connection method can, according to the temperature requirements of the roots, independently control the corresponding electric heating wire to heat through the temperature control component to meet the needs of local heating and save energy.

[0011] Preferably, in the above-mentioned substrate trough-type cultivation root zone temperature control heating device, the temperature control unit includes a thermostat and a temperature control probe. The thermostat is connected to the power supply and is electrically connected to the electric heating wire through a connecting wire. The temperature control probe is arranged in the cultivation substrate bag and is electrically connected to the thermostat. The root temperature is monitored in real time through the temperature probe. When the temperature is too low, the thermostat controls the electric heating wire to heat to meet the root temperature requirements. When the temperature is too high, the thermostat controls the electric heating wire to stop heating.

[0012] Preferably, in the above-mentioned substrate trough-type cultivation root zone temperature control heating device, the number of the temperature control probes is multiple, and the multiple temperature control probes are evenly distributed in the cultivation substrate bag. The temperature control probe can accurately monitor the temperature. The setting of multiple temperature control probes can better monitor the temperatures of the roots in different areas.

[0013] Preferably, in the above-mentioned substrate trough-type cultivation root zone temperature control heating device, there is a gap between the outer side wall of the cultivation substrate bag and the inner side wall of the cultivation trough. This facilitates the fixation of the cultivation substrate bag and the cultivation trough.

[0014] Preferably, in the above-mentioned substrate trough cultivation root zone temperature control heating device, the number of the cultivation troughs is multiple, and the multiple cultivation troughs are arranged side by side at intervals. The thermostat is electrically connected to the electric heating wires in each cultivation substrate bag through the connecting wires. It can meet the monitoring of multiple cultivation troughs at the same time, and can not only realize heating at the same time, but also realize layout heating.

[0016] 1. The structure of the present invention is simple, the operation is convenient, and the cost investment is low.

Through the setting of the temperature control component, the root temperature can be monitored and fed back in real time, and the operation of the heating component can be controlled to meet the temperature requirements of the root area.

[0018] 3. The present invention can control the heating of the roots in the whole area at the same time, and can also meet the local heating, and has a wide application range. BRIEF DESCRIPTION OF THE DRAWINGS
