Soilless cultivation technology
January 20, 2025
Deep liquid flow technology (DFT) refers to a soilless hydroponic technology in which the roots of plants grow in a relatively deep and flowing nutrient solution layer. The planting trough contains a nutrient solution of about 5 to 10 cm or even deeper, and the crop roots are placed in it. At the same time, a water pump is used to intermittently supply liquid to circulate the nutrient solution to replenish oxygen in the nutrient solution and make the nutrients in the nutrient solution more uniform.
The deep liquid flow hydroponic facility consists of a planting trough, a planting net or planting plate, a liquid storage tank, a circulation system and other parts. It is the earliest soilless cultivation technology developed for commercial production of agricultural crops. It can produce fruit and vegetables such as tomatoes, cucumbers, peppers, wax gourds, loofahs, melons, watermelons, and leafy vegetables such as Chinese cabbage, Chinese cabbage, lettuce, water spinach, and chives.
