Description

Technical Field

[0001] The invention relates to the technical field of orchid cultivation, and in particular to an automatic cultivation device and method for orchid planting. Background Art

[0002] Orchid: epiphytic or terrestrial herb, with several to many leaves, usually growing at the base or lower nodes of the pseudobulb, in two rows, ribbon-shaped or rarely oblanceolate to narrow elliptic, with a broad sheath at the base generally surrounding the pseudobulb, with joints, and a raceme with several or many flowers, in colors including white, pure white, white-green, yellow-green, light yellow, light yellow-brown, yellow, red, blue, and purple. Orchids are very different from tropical orchids with large and colorful flowers. They do not have eye-catching colors, nor large flowers and leaves, but have a simple, quiet, elegant and noble temperament, which is in line with the aesthetic standards of the Chinese people. Therefore, they are promoted for cultivation. Among them, hydroponic orchids, as a recently popular cultivation method, are deeply loved by the general public.

[0003] During the hydroponic orchid cultivation process, the nutrient solution needs to be kept flowing. In the existing cultivation devices, a water pump is often used to continuously circulate the nutrient solution.

The roots are prone to hypoxia and necrosis, which affects the orchid cultivation. In addition, hydroponic orchids require nitrate, phosphorus and potassium fertilizers to fertilize the nutrient solution. Therefore, an automated cultivation device and method for orchid planting are proposed. Summary of the invention
