DETAILED DESCRIPTION

[0041] Embodiment 1: The present invention includes a chassis 1, in which a group of evenly distributed planting boxes 4 are fixedly connected, each of which has a group of planting troughs, the chassis 1 is fixedly connected to a mounting plate 7, the mounting plate 7 is fixedly connected to a group of evenly distributed water pipes 5, each of which is fixedly connected to an end joint 6, and each of which is provided with a nozzle corresponding to the corresponding planting trough; the chassis 1 is fixedly connected to a storage box 8, the storage box 8 is provided with a group of water tanks 9, the storage box 8 is fixedly connected to a drain valve 19 corresponding to each of the water tanks 9, the storage box 8 is fixedly connected to an inlet valve 14 corresponding to each of the water tanks 9, and the storage box 8 is provided with a salinity meter 20 and a water level meter 38 corresponding to each of the water tanks 9.

[0042] The salt content meter, also known as the salinity meter, is an instrument used to quickly determine the weight percentage concentration or refractive index of a salt (sodium chloride) solution. It is widely used in industrial sectors such as salt production, food, and beverages, as well as agricultural production and scientific research. It is usually composed of a sensor, a measuring circuit, and a data processing device. There are two types of conductivity sensors: electrode type and inductive type. The sensor of the salt content meter is composed of a pair of electrodes with a layer of platinum or rhodium (not easy to corrode) on the surface with stable physical and chemical properties. In order to prevent the electrodes of the sensor from short-circuiting due to the adhesion of foreign matter, the sensor should be cleaned once every month or so. When cleaning, wipe with a soft cloth, and never scrape with hard objects to avoid damaging the platinum or rhodium coating. The salt content meter is easy to operate, and the user can quickly read the salt concentration or specific gravity of seawater. It can be used for the concentration management of seawater used in oceans, fisheries, and farms, seawater or artificial seawater used in aquariums, and salt water used for stored fish. The conductivity of the aqueous solution increases with the increase of salt content, that is, the greater the salt content, the smaller the resistance and the better the conductivity. When light enters another medium from one medium, it will be refracted, and the ratio of the sine of the incident angle is always a constant value, which is called the refractive index. By using the property that the content of soluble substances in salt solution is directly proportional to the refractive index under normal conditions, the refractive index of the salt solution can be measured, so that the concentration of the salt can be calculated.
