Description

Water culture device

Technical Field

The utility model relates to a seedling culture technical field especially relates to a hydroponic device.

Background

Hydroponics is a novel soilless cultivation mode of plants, also called nutrient solution cultivation, and the core of the hydroponics is that the root systems of the plants are directly soaked in nutrient solution, and the nutrient solution can replace soil and provide growth factors such as water, nutrients, oxygen and the like for the plants, so that the plants can normally grow. After the water culture method is adopted, the plants can directly absorb the nutrients and water in the nutrient solution through roots, people can manually prepare the solution with balanced nutrition, and balanced diet of the plants is realized, which is obviously much easier than finding perfect soil. Because the solutions are all arranged in the container, the solutions can be recycled, cannot flow into soil to influence the environment, and are safe, reliable and sustainable. With these advantages, the water culture technology is widely applied to agricultural production, scientific research, urban greening and even family green plant culture.

To the indoor water planting mode of small-scale such as scientific research and family green plant cultivation, current hydroponic device adopts box-like container more on the market for hold the nutrient solution. The box-shaped container is provided with a box cover, and a seedling hole is arranged on the box cover. The inner side of the hole is connected with a seed support, and the lower end of the seed support is opened and is communicated with the nutrient solution. The water culture device is simple and has a limited application range. The seed is fixed mainly through the kind support on the lid to current water planting box, and the kind support must be with the nutrient solution intercommunication for supply with nutrition, and so, the lower extreme aperture of kind support has greatly restricted the plant species scope that the device can be suitable for. In addition, the nutrient solution is changed regularly to current water planting box, perhaps exposes a part of plant root system on the nutrient solution liquid level, carries out the aerial growth and cultivates to satisfy the demand of plant root system to oxygen. However, these measures can only alleviate the problem of oxygen deficiency of the root system to a certain extent, and cannot completely solve the problem. Meanwhile, the nutrient solution is static within a certain period of time, so that the problems of inorganic salt deposition, uneven distribution of local nutrient elements, accumulation and attachment of harmful metabolites and microorganisms and the like are easily caused, and the nutrient absorption efficiency and the growth condition of plants are influenced. On the other hand, the existing device is relatively simple and easy, cannot realize the monitoring to the water planting environment, and cannot carry out timely adjustment to the culture condition. Nor do they provide a convenient and straightforward data acquisition model in scientific research.
