Overview
Shallow flow hydroponics: Its characteristic is that the circulating liquid flow is in the form of a membrane, with only a few millimeters of shallow liquid flowing through the bottom of the cultivation tank. The bottom of the root pad of hydroponic crops contacts the shallow liquid flow to absorb water and fertilizer, and the upper part is exposed Absorbing oxygen in moisture better solves the contradiction between water absorption and oxygen absorption by the root system.
However, there are shortcomings such as shallow liquid flow, unstable liquid temperature, plants are easy to wither in case of power outage, and rhizosphere environment stability is poor, which limits its further development.
This method is widely used on some crops such as lettuce and tomatoes. The composition of hydroponic facilities is mainly nutrients
It consists of five parts: liquid tank, cultivation bed, liquid adding system, liquid drainage system and circulation system.
