Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of plant culture device, concretely relates to a water culture device of experimental silybum marianum aeration. BACKGROUND

[0002] Silybum marianum, also known as water fly pheasant and milk thistle, is an annual or biennial herbaceous plant of the family Asteraceae. Silybum marianum is suitable for planting in alpine regions. It is tolerant to barren, cold, drought and high temperature, and has strong adaptability, and does not require high soil and water. Currently, silybum marianum is planted in wasteland, wasteland, saline-alkali land and mountainous areas. It is difficult to plant silybum marianum in low-lying waterlogged land, so the water culture research of silybum marianum has great significance for the future planting of silybum marianum.

[0003] In today's accelerating urbanization process, land resources are becoming increasingly scarce. Traditional flat planting methods occupy a large area of land and have low land utilization rate. In addition, it is difficult to control diseases and insect pests in the soil, which can easily cause plants to become ill. The nutrients in the soil are limited, and the development of plant roots is limited, which may affect the growth and health of plants in the long run. Traditional soil planting methods require a large amount of water resources for irrigation, and are prone to waste of water resources and soil pollution.

[0004] With the continuous innovation of modern agricultural technology, traditional soil planting methods cannot meet people's demand for efficient, environmentally friendly and intelligent planting. Water culture technology as a new type of soilless cultivation method, by providing suitable nutrient solution and growth environment for plants, realizes the rapid growth and high yield of plants.

[0005] The plant water culture frame adopts a three-dimensional planting method, which can greatly improve the space utilization rate. The plant water culture frame supplies water and nutrients required for plant growth by recycling the nutrient solution, which can greatly reduce the waste of water resources, and the plant water culture frame occupies a small area of land, which can meet the space limitations of the laboratory.

[0006] Although the current water culture device realizes soilless cultivation, it is not widely used in the water culture direction of Chinese herbal medicine, especially the water culture direction of silybum marianum. There is still a lot of space for the application of water culture device. The current water culture device lacks aeration device and automatic water level monitoring system. Aeration is crucial to increasing the oxygen content of nutrient solution, maintaining root respiration and preventing eutrophication. Lack of aeration device will lead to reduced oxygen, blocked root respiration, affected plant nutrient absorption and growth, reduced yield and quality, and increased management difficulty and cost. In the water culture system in the experimental field, the nutrient solution is crucial to the growth of plants, and the lack of automatic water level monitoring system may lead to fluctuation of liquid level due to improper operation or negligence, further affecting the accuracy of the experiment.
