Planting box

Abstract

The invention discloses a planting box which comprises a box body, a planting plate, a lifting device, a water level detector and a controller with a preset water level threshold value in the inside. The lifting device is used for controlling vertical movement of the planting plate in the box body, a water trough for adding liquid required by plant growth is arranged at the bottom of the box body, the planting plate is located at the upper portion of the water trough, the water level detector is used for detecting the water level height in the water trough, the controller is used for controlling the lifting device to make the planting plate move down for a preset distance when the water level height detected by the water level detector is lower than the water level threshold value. The water level detector can detect the water level height in the water trough. The controller controls the planting plate move down for the preset distance when the detected water level height is lower than the water level threshold value, so that root systems of plants are fully located in the liquid in the water trough. Therefore, the root systems of plants can be prevented from being exposed above a water level line, and further normal growth of the plants is ensured.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a planting box. Background technique [0002] With the improvement of people's living standards, the planting box has become an indispensable household ornamental device in people's life. It can also be used to grow vegetables, and can also serve as an educational purpose about plant growth. [0003] In order to meet the growth of plants, the planting box needs to provide the necessary growth conditions for the plants. For the hydroponic planting box, the capacity of the water tank in the plant box is fixed at present. For some plants with a long growth cycle, frequent manual addition is required. The nutrient solution is not only inconvenient to operate, but also not conducive to the normal growth of plants. In addition, when the liquid in the water tank decreases, the water level in the water tank will gradually decrease, which will cause some roots of the plants to be exposed ab...

[0003] In order to meet the growth of plants, the planting box needs to provide the necessary growth conditions for the plants. For the hydroponic planting box, the capacity of the water tank in the plant box is fixed at present. For some plants with a long growth cycle, frequent manual addition is required. Nutrient solution is not only inconvenient to operate, but also not conducive to the normal growth of plants

In addition, when the liquid in the tank decreases, the water level in the tank will gradually decrease, which will cause some roots of the plants to be exposed above the water level, thereby affecting the growth of the plants
