Description

Technical Field

[0001] The present application relates to the technical field of planting racks, and in particular to a vegetable planting rack with a circulating supply of a flowing nutrient solution. Background Art

[0002] Soilless cultivation refers to a cultivation method that uses water, peat, forest leaf mold, vermiculite and other media as the substrate for the plant roots to fix the plants, so that the plant roots can directly contact the nutrient solution. The composition of the nutrient solution in soilless cultivation is easy to control and can be adjusted at any time. Soilless cultivation is divided into hydroponics, mist (air) cultivation and substrate cultivation according to the different cultivation media. Hydroponics refers to a cultivation method in which the plant roots are in direct contact with the nutrient solution without the use of a substrate. The nutrient film method is often used for hydroponics, that is, a very thin layer of nutrient solution that continuously circulates through the crop root system, which not only ensures a continuous supply of water and nutrients to the crop, but also continuously supplies fresh oxygen to the root system.

The rotating disk 74 uses the filter holes 741 on the surface to block impurities and uses the removal grooves 742 to push out impurities adhering to the surface of the rotating disk 74 during rotation. While the cleaning rod 73 rotates and drives, the brush at the upper end is used to clean the surface of the rotating disk 74 and clean the impurities out of the filter shell 71 to complete the filtration of the nutrient solution. The filtered nutrient solution enters the inner side of the liquid storage tank 2 along the reflux pipe 6 to realize recycling.
