Soilless culture device

Abstract

The invention discloses a soilless culture device. The soilless culture device comprises a support and plantation water pipes. The support comprises stand columns for fixation. At least two layers of plantation water pipes are arranged in parallel on the stand columns from top to bottom through supporting pieces. The stand columns fix the supporting pieces through fixing pieces. A water inlet pipe is arranged at one end of the plantation water pipe arranged on the top layer. A water outlet pipe is arranged in the middle of one end of the plantation water pipe arranged at the bottom layer. The plantation water pipes located on the adjacent layers are connected through connecting pipes. Capillary pipes are arranged at the connection positions between the plantation water pipes and the connecting pipes and at the connection position between the plantation water pipe and the water outlet pipe. The original manner that a supporting frame supports the plantation water pipes is changed into the manner that the stand columns support the plantation water pipes. The stand columns are directly and vertically fixed, so that the occupied space of the stand columns is small, and the stand columns are easy to fix to a window. The arranged capillary pipes can discharge culture liquid in the plantation water pipes completely through the siphon principle. In this way, it can be guaranteed that rotten roots and other impurities in the plantation water pipes can be discharged, the plantation water pipes are clean, the situation that because roots of plants are always in the culture liquid, the oxygen concentration, the EC value and the PH value of the culture liquid is out of control can be avoided, the respiration function of the roots of the plant is well improved, and growth of the plants is promoted.

Description

technical field [0001] The invention relates to the technical field of cultivation technology equipment, in particular to a soilless cultivation device used in residences, offices, hotels, classrooms and corridors. Background technique [0002] As the process of urbanization continues to intensify, the area of ​​arable land continues to decrease and the pollution becomes more and more serious. The problem of vegetable safety is difficult to solve, and the utilization rate of urban window sills is low. At present, the support frame supporting the planting water pipes in the existing soilless culture device is relatively large. When used in residences, offices, hotels, classrooms and corridors, the large support frame occupies a large area, which makes its original The small space is more narrow, and the connecting pipe between the upper and lower layers of the planting water pipe is connected to the center of the end of the planting water pipe or the upper part of the center,...

Problems solved by technology

[0002] As the process of urbanization continues to intensify, the area of ​​cultivated land continues to decrease and pollution becomes more and more serious, the problem of vegetable safety is difficult to solve, and the utilization rate of urban window sills is low

At present, the supporting frame supporting the planting water pipe in the existing soilless cultivation device is relatively large. When used in houses, offices, hotels, classrooms and corridors, the large supporting frame makes it occupy a large area, making it originally The small space is narrower, and the connecting pipe connected between the upper and lower layers of the planting water pipe is connected to the center or the upper part of the center of the planting water pipe, so that the bottom of the planting water pipe will always have a culture solution, so that the roots of the planted plants It has been in the culture medium, causing the oxygen concentration, EC value, and pH value of the culture medium to be out of control, which seriously affects the growth of plants.
