Plant growth cabinet with automatic height adjustment function of lamp board

Abstract

The invention discloses a plant growth cabinet with an automatic height adjustment function of a lamp board. The cabinet comprises a cabinet body, a weighing module of a transplanting plate, a root drying module, a height automatic adjustment mechanism of the lamp board and a main controller; a root drying function of roots of plants is achieved through the root drying module; in the growing process of the plants, the weight of the plants is detected periodically through a weighing sensor by the main controller, in order to ensure accuracy of weighing and prevent influence on weighing resultscaused by buoyance of culture liquid, the weighing module of the transplanting plate and the root drying module are combined, and collection of weighing signals is conducted when the roots are dried;the height automatic adjustment mechanism and the weighing function of the weighing module of the transplanting plate are combined, and the height of the lamp board is adjusted according to weight data of the plants detected by the weighing module of the transplanting plate, so that the height of the lamp plate fits with the growth height of the plants.

Description

technical field [0001] The invention belongs to the technical field of plant soilless cultivation, and in particular relates to a plant growth cabinet with the function of automatically adjusting the height of a lamp panel. Background technique [0002] The plant growth cabinet does not use soil, but adopts the hydroponics method with mature technology. In the hydroponic method, plastic foam boards are used to fix the plants. The roots of the plants do not grow in the soil at all, but are completely immersed in the culture solution. The function of the soil is to provide nutrients and water, and the culture solution not only provides water, but also provides Various elements needed for plant growth, including macronutrients such as nitrogen, phosphorus and potassium, and trace elements such as zinc, iron and manganese, so there is no need to use soil for cultivation. [0003] In the process of plant growth, the roots of the plant will grow downward as in the soil, but there...

Problems solved by technology

If the roots and stems of plants are soaked in water for a long time, it is not conducive to the division of plant cells, which can not only promote growth, but also cause some adverse reactions of plants due to long-term soaking, and sometimes cause stop growth or even death in severe cases

[0004] Light is an indispensable energy source for plant growth. The light panels in the plant growth cabinet provide light for the plants, but the position of the traditional light panels is fixed, and the height of the plants is constantly increasing during the growth process (especially for growing In terms of plant species with obvious changes in height during the process), and the illumination required by different plant species is also different, so the existing light boards cannot adapt to the required illumination distance of different plant species at different growth heights. One Drawback of Grow Lights
