Culture solution planting device

Abstract

The invention relates to a culture solution planting device. The culture solution planting device can maintain best culture solution conditions of the concentration, the temperature and the like of a culture solution which is adjusted and fed in advance, even feeding is achieved, and the device can provide proper nutrient, oxygen and an environment for a planted crop stably. The culture solution planting device comprises at least a planting groove and a planting bed, wherein the adjusted culture solution is fed into the planting groove, so that the culture solution can circulate in a flowing state all the time, and the water level of the culture solution can be adjusted. A plurality of liquid feeding ports which provide the culture solution for the planting groove are arranged at intervals on one side of the planting groove along the length direction, besides, a plurality of liquid discharging ports which discharge the culture solution from the planting groove are arranged at intervals on the other side of the planting groove along the length direction, therefore, the flowing direction of the culture solution which flows in the planting groove is a width direction, and the culture solution in the planting groove is replaced once to ten times per hour.

Description

technical field [0001] The present invention relates to a culture solution cultivation device, and more particularly, to a culture solution cultivation device that makes a culture solution for crop cultivation flow in a cultivation tank and supplies nutrients in the culture solution to roots to grow crops. Background technique [0002] In a culture solution cultivation apparatus that supplies a culture solution into a cultivation tank and circulates the culture solution to cultivate crops, the culture solution flows along the longitudinal direction of the cultivation tank to provide nutrients to the crops. [0003] In this case, as the scale of cultivation with the culture solution increases, the cultivation tank becomes extremely long, and the flow path of the culture solution flowing in the longitudinal direction in the cultivation tank becomes longer. [0004] In this situation, the culture solution flowing in the cultivation tank tends to stagnate, and a uniform flow can...

Problems solved by technology

In addition, the hydroponic cultivation device of this document 2 makes the culture solution flow on the cultivation bed 3 in the form of an extremely thin film, so it is different from the cultivation device that flows the culture solution into the cultivation tank and circulates it, and the type of crops to be applied is affected to some extent. limit

In addition, the roots are mostly exposed in the air layer produced on the membranous culture medium layer. However, regarding the airtightness of the air layer, etc., the humidity environment of the air layer is not considered, and it cannot be sufficiently prevented from being caused by the accompanying roots. Root damage due to cooling by latent heat of water evaporation from the surface

Furthermore, the hydroponics device of Patent Document 2 requires the cultivation bed 3 to be inclined, so that the crops are planted in an inclined state no matter what.
