The composition of the nutrient solution in soilless cultivation is easy to control and can be adjusted at any time. It has the advantages of saving water, saving fertilizer, high yield, cleanliness, pollution-free, and avoiding continuous cropping obstacles. For example, as shown in the existing patent technology: After searching, the China Patent Network discloses a mobile nutrient solution circulation supply vegetable planting rack (Announcement No. CN216363002U). During use, this type of device can effectively filter the nutrient solution when the refluxed nutrient solution flows back to the inside of the nutrient solution tank through the first connecting pipe by setting a filtering component, filter out the fallen rhizomes of plants in the refluxed nutrient solution, and prevent the fallen plant rhizomes from entering the inside of the nutrient solution tank to cause blockage, thereby achieving the purpose of effectively filtering the recycled nutrient solution.

[0003] However, the vegetable cultivation racks adopted in the above-mentioned patents and the existing market still have some shortcomings: the existing method of layer-by-layer diversion and then integrated filtration, when the refluxed nutrient solution converges, it is very easy to block the reflux pipeline due to excessive impurities, resulting in poor circulation flow performance, requiring frequent cleaning by staff. To this end, the technicians in this field provide a vegetable cultivation water and fertilizer integrated supply device to solve the problems raised in the above-mentioned background technology.
