Soilless cultivation device for nontoxic cucumber cultivation

Abstract

The invention discloses a soilless cultivation device for nontoxic cucumber cultivation. The soilless cultivation device for nontoxic cucumber cultivation mainly includes a bottom plate, and side plates which are vertically arranged upwards are fixedly glued to the left and right sides of the upper surface of the bottom plate; during up-and-down movement of a tray, through transmission of jackingrods, piston plates can be driven to move up and down in planting tubes, at this time, during movement of the piston plates, the size of planting areas above the piston plates can be altered, at the same time, the exposed heights of plants located on the upper surfaces of the piston plates can also be adjusted to a certain degree, in this way, the soilless cultivation device can assist in adjusting the illumination effect over the plants, and therefore the survival rate of the plants can be increased; a water pump is adopted to convey nutrient liquid inside a nutrient liquid box to the planting tubes separately, so that soilless cultivation of the plants is achieved; meanwhile, through up-and-down movement of the piston plates, the liquid levels of the planting tubes can be adjusted, surplus nutrient liquid can be extruded out simply through jacking of the piston plates when the liquid levels of the planting tubes are excessively high, and therefore the liquid levels of the planting tubes can be integrally balanced effectively.

Description

technical field [0001] The invention relates to the biological field, in particular to a soilless cultivation device for cultivating non-toxic cucumber seedlings. Background technique [0002] Soilless cultivation refers to a cultivation method in which water, peat or forest leaf humus, 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 matrix cultivation according to different cultivation media. Hydroponics refers to the cultivation method in which the plan...

Problems solved by technology

[0005] Existing cucumber cultivation mostly adopts soilless cultivation, but the current soilless cultivation device has the shortcomings of inconvenient adjustment of cultivation height and nutrient solution level. At this time, it is easy to burn the seedlings if the nutrient solution is added, and it is not easy to take it out. In many cases, it is mostly to discharge liquid, which is inconvenient overall
