Description

A hydroponic system for high-throughput corn roots

technical field

The utility model belongs to the field of plant soilless cultivation, in particular to a hydroponic system for high-throughput corn root system.

Background technique

Soilless cultivation technology is a method of cultivating plants with other things without soil, including hydroponics, fog (air) cultivation, and substrate cultivation. In soilless culture, artificially prepared culture medium or matrix is used to supply the needs of plant mineral nutrition. Hydroponic flowers are a new generation of high-tech agricultural projects that adopt modern bioengineering technology and use physical, chemical, and biological engineering methods to domesticate ordinary plants and flowers so that they can grow in water for a long time. The composition of nutrient solution in soilless culture is easy to control. And it can be adjusted at any time, in places where the light and temperature are suitable and there is no soil, such as deserts, beaches, and deserted islands, as long as there is a certain amount of fresh water supply, it can be carried out. The suburbs and families of metropolises can also grow vegetables and flowers by soilless culture. Soilless cultivation refers to a cultivation method that uses substrate or nutrient solution to irrigate without using natural soil. It is mainly used in vegetables or flowers. It is a high-yield, high-quality advanced technology that saves water, fertilizer and labor. At present, soilless cultivation The technology has been applied and developed in more than 100 countries around the world.

At present, the bottoms of common soilless cultivation boxes are mostly closed, and since there are no ventilation holes, it is easy to accumulate water to cause diseases such as root rot of cultivated plants, thereby causing the plant to die. However, most of the existing soilless cultivation techniques use hydroponics, and the root systems of many plants are not suitable to be soaked in the nutrient solution all the time, which will cause rotten roots, hypoxia and other phenomena, which will seriously affect the growth of plants, and even cause problems such as death. The existing spray-type aeroponic technology has poor atomization effect.
