Description

Possesses culture tank that keeps nutrient solution liquid level

Technical Field

The present invention relates to a culture tank capable of maintaining the liquid level of a nutrient solution.

Background

At present, in many laboratories, cultivation of peanuts is still carried out in order to be able to better carry out peanut research. Therefore, research data can be provided for peanut planting so as to help the peanut planting. The peanut growth condition is better observed in the laboratory and is all cultivated by adopting the nutrient solution, because the nutrient solution has volatility and is absorbed by plants, the height of the nutrient solution is continuously reduced, the nutrient solution can not contact the roots of the plants easily after a long time, thus the cultivation failure is caused, the productivity is wasted if a specially-assigned person is arranged to take care, and the cost is increased. Therefore, the cultivation research of peanuts is inconvenient, and a cultivation device capable of keeping the height of the nutrient solution unchanged is needed, so that the growth and research of peanuts can be observed conveniently.
