Soilless Farms: Revolutionizing Agriculture With Fully Automated Farming

2023-04-03

The era is developing rapidly, and the agricultural revolution has also been ongoing. One of the typical representatives of the modern agricultural revolution is soilless cultivation. When it comes to soilless cultivation, it is estimated that everyone has heard about it, but few people really understand it.

What is soilless cultivation technology?

Soilless cultivation is literally a cultivation technique that does not use soil. Actually, this is not entirely correct. This planting method refers to the method of using other substrates or only substrates for seedling cultivation without using natural soil. After planting, nutrient solution is used for cultivation.There are many advantages of soilless cultivation technology. It is the artificial creation of a root environment to replace the soil environment. This can effectively save water and fertilizer, improve yield, facilitate management, and also be clean and pollution-free. The most important thing is that it can greatly save land and expenses.

What are the applications of soilless cultivation techniques?

Generally, soilless cultivation mainly includes three aspects: hydroponics, aeroponic, and substrate cultivation. This cultivation mode is generally applicable to three crops: flowers, fruits, and vegetables.

Hydroponics refers to the cultivation method in which the roots of plants are directly in contact with nutrient solutions without using substrates. Early hydroponic cultivation was limited to immersing plant roots in nutrient solutions for growth, but this approach had significant drawbacks, which could lead to plant hypoxia and, in severe cases, root death. The hydroponic method of nutrient liquid film method is often used. Even a thin layer of nutrient liquid continuously circulates through the root system of the crop, ensuring continuous supply of water and nutrients to the crop, as well as continuous supply of fresh oxygen to the root system.The hydroponic tower planting system is a typical representative of hydroponic cultivation, which is suitable for both small area household planting and large area planting.
Aeroponic is a more advanced soilless cultivation method in the past two years. It does not even need to directly contact the roots with nutrient solution, but rather exposes the roots of plants to the air, and regularly sprays the nutrient solution onto the roots. The aeroponic system consists of four parts: high-pressure atomization pump or ultrasonic atomizer, stainless steel water delivery pipe or PE pipe, aerosol cultivation box containing planting plate or aerosol cultivation barrel, water and fertilizer device filtering device and control system.Aeroponic system is currently the most water-saving planting method for soilless cultivation technology, with high water recycling efficiency. It has great demonstration significance for sustainable development of agriculture.

substrate system

Substrate cultivation is the lowest cost and easiest to operate planting method in soilless cultivation techniques, which does not rely on traditional soil planting. Compared to other soilless cultivation methods, this cultivation method is more cost-effective.Common substrate cultivation equipment includes Dutch bucket, strawberry planting gully and green wall.

Soilless cultivation technology is a product of the agricultural revolution. In advocating for sustainable development today, new agricultural technologies will inevitably follow the process of sustainable development.
