Device for cultivating hydroponic plants

Abstract

Disclosed is a device for cultivating hydroponic plants. The device comprises a nutrient solution holding disc for holding a nutrient solution, a plurality of first protruding portions and a plurality of second protruding portions. The nutrient solution holding disc at least comprises a first long side wall and a second long side wall which are opposite. The plurality of the first protruding portions are contacted with the first long side wall respectively and not contacted with the second long side wall to form first openings respectively. The plurality of the second protruding portions are contacted with the second long side wall respectively and not contacted with the first long side wall to form second openings respectively. The plurality of the first protruding portions and the plurality of the second protruding portions are arranged at intervals, and extending directions of the plurality of the first protruding portions and the plurality of the second protruding portions are vertical to the injection direction of the nutrient solution.

Description

technical field [0001] The present invention relates to a hydroponic plant cultivation device, especially a hydroponic plant cultivation device for achieving high oxygen permeability (high oxygen permeability). Background technique [0002] Hydroponics is one of the methods of soilless culture. It mainly soaks the roots of plants in the nutrient solution, and uses the nutrient solution to provide the nutrients and elements needed by the plants to replace the traditional soil cultivation method. Therefore, it is also called nutriculture. [0003] Because the traditional hydroponic cultivation uses sponges to fix the plants, and the roots of the plants are directly soaked in the nutrient solution, and the root hypoxia often occurs when the plant roots are soaked in the nutrient solution for a long time, which not only affects the growth of the plants, but also may Causes cell death at the root, ie root rot which leads to crop death. In order to avoid such problems, known tec...

Problems solved by technology

However, the existing method must use an external device to continuously feed the gas, which not only has the disadvantages of increased cost and power consumption, but also cannot effectively solve the problem that plants are prone to rot in hydroponic cultivation.
