Abstract

The invention discloses an intelligent floating seedling culture device capable of automatically regulating parameters of a nutrient solution. A hydraulic telescopic rod drives a support to move downwards in a tank to soak roots of seedlings in a solution layer, in a seedling culture period, a concentration detector detects the concentration of the nutrient solution in the solution layer, when thenumerical value detected by the concentration detector is lower than that of the concentration of the nutrient solution required for seedling culture, a PLC controls a solution storage tank to open,the high-concentration nutrient solution stored in the solution storage tank enters the solution layer via a nutrient solution flow controller and a solution supply pipe to supplement the concentration of the nutrient solution in the solution layer, so that the concentration of the nutrient solution in the solution layer is always kept in a concentration range required for seedling culture production, and healthy development of seedlings is guaranteed. Meanwhile, a temperature is used for detecting temperature of the solution in the solution layer, when the temperature of the solution in the solution layer is too low, the PLC controls a root heating wire to heat the solution, the seedlings are ensured to develop at the best temperature, and the development speed and quality are improved.

Description

technical field [0001] The invention belongs to the technical field of seedling raising equipment, in particular to an intelligent floating seedling raising device for automatically regulating the parameters of nutrient solution. Background technique [0002] Soilless cultivation refers to a cultivation method in which water, peat or forest leaf mulch, vermiculite and other media are used as the substrate for the root system of the plant to fix the plant, and the root system of the plant can directly contact the nutrient solution. The composition of nutrient solution in soilless culture is easy to control and can be adjusted at any time. In places where the light and temperature are suitable but there is no soil, such as deserts, beaches, and deserted islands, as long as there is a certain amount of fresh water supply, it can be carried out. Soilless cultivation is divided into hydroponics, mist (air) cultivation and substrate cultivation according to different cultivation ...
