Description

Radish seedling hydroponic device

technical field

The utility model relates to the field of seed hydroponics, in particular to a radish seedling hydroponics device.

Background technique

Seed germination refers to a series of ordered physiological and morphogenetic processes starting from imbibition. Seed germination requires proper temperature, proper amount of water, sufficient air, and proper amount of water to ensure that the seed coat swells and softens after the seed absorbs water, which can allow more water and oxygen to enter the seed embryo, and start the physiological activities of the seed embryo cells at the same time. Metabolic wastes and carbon dioxide are excreted through the seed coat; sufficient air meets the respiration needs of the seeds during the germination process, and suitable temperature ensures the respiration of the seeds.

At present, there are two main types of seed vegetables (such as radish seedlings), hydroponics and soil cultivation. Since hydroponics is not affected by the season and can precisely control the nutrients of vegetables, it has been widely used in agricultural production, large-scale Extraction and scientific research of nutrients from sprouts or seedlings.

The traditional hydroponic method for seed vegetables includes two steps of germination and germination: firstly, the seeds are laid on wet gauze or wet filter paper, and then two or more layers of wet gauze or wet filter paper are placed on the seeds, and the gauze is placed regularly. Or spray the culture solution on the filter paper; after the seeds are successfully germinated, the buds are transplanted into the nutrient solution for cultivation. This method has the following defects: (1) In the stage of germination and germination, a large amount of gauze or filter paper is required, which wastes consumables; during the germination process, by spraying nutrient solution on the gauze and the seeds are piled on the gauze or filter paper in large quantities, it is impossible to ensure that the seeds germinate. The required water and humidity, rotten buds and rotten seeds are more, and the seeds are wasted; (2) After the seeds germinate

SUMMARY OF THE INVENTION It is necessary to transplant young buds, which is complicated to operate and has a large workload. Moreover, due to the accumulation of seeds, the young buds are easily broken during the transplanting process, and the transplanting is difficult and the transplanting success rate is low. Therefore, how to design a hydroponic device integrating germination and sprout cultivation is a technical problem to be solved urgently by those skilled in the art.
