A kind of facility plant led light temperature synergistic cultivation device and cultivation method

Abstract

The invention relates to a facility plant LED light and temperature coordinated cultivation device and method. The device comprises an LED light supplementing device, a transmission pipeline and a heat dissipation pipeline located in a root region of cultivated plants. The LED light supplementing device comprises a heat dissipation part. One end of the transmission pipeline is connected with the heat dissipation part, and the other end of the transmission pipeline stretches to the root region of the cultivated plants and is connected with the heat dissipation pipeline. A heat transfer medium is arranged in the transmission pipeline, absorbs heat generated by the LED light supplementing device and conducts the heat to the heat dissipation pipeline in the root region of the cultivated plants, and the root region of the cultivated plants is heated. Furthermore, the transmission pipeline is a circulating pipeline. Operating heat of the LED light supplementing device can be fully used for heating the root region of the facility plants while LED light supplementing is achieved, the light and temperature coordinated effect is achieved, and photosynthesis of the plants is practically improved.

Description

technical field [0001] The invention belongs to the technical field of facility agricultural plant soilless cultivation, and in particular relates to a simple light-temperature coordinated facility plant that recycles the heat provided by the operation of LED supplementary lights and is used for heating the root zone of facility plant substrate cultivation Cultivation device and cultivation method. Background technique [0002] The production of facility plants (vegetables, flowers, etc.) is a way of producing off-season vegetables in winter and spring in solar greenhouses, plastic greenhouses, multi-span greenhouses and other facilities. Indispensable technical means. Taking protected vegetables as an example, the cultivated area of ​​protected vegetables in my country has reached nearly 4 million hectares, most of which use soil cultivation as the main method, and are carried out in solar greenhouses and plastic greenhouses, while soilless cultivation only accounts for a ...

Problems solved by technology

At the same time, due to bad weather such as rain, snow, smog, etc., weak light and low light adversity or frequent occurrence of continuous cloudy days seriously restrict the growth and development of facility plants. LED supplementary light has become a cultivation environment control technology equipment that must be considered for facility plant cultivation.

[0004] At present, low temperature, weak light and low light stress have become the realistic factors that limit the high-quality, high-yield and stable production of protected plants. It is urgent to develop the substrate cultivation technology and equipment of protected plants that are suitable for the application of solar greenhouses and plastic greenhouses in my country and have the ability to warm the root zone. It can overcome the inherent problems of soil cultivation, and can also solve the practical technical problem of high environmental temperature requirements for facility plant substrate cultivation, fundamentally improve the production of facility vegetables in my country, and reduce resource waste and environmental hazards.

At present, there is a lack of energy-saving facility plant light-temperature synergistic cultivation methods and control devices
