What is soilless culture?

Soilless culture refers to the cultivation of crops with nutrient solution instead of natural soil, which can provide water, nutrients, oxygen and temperature for crops instead of natural soil, so that crops can grow normally and complete their whole life cycle. As we all know, the growth of crops in traditional agriculture is inseparable from soil, such as grain, cotton, oil, vegetables, fruit trees, tea, flowers, tobacco and so on. , must rely on soil culture. It can be said that agricultural production, especially planting, is a farming technique that uses soil, and agriculture is closely related to soil. Since Professor Gehrig successfully planted soilless tomatoes in 1929, crop cultivation has finally got rid of the shackles of natural soil and entered an attractive industrial production development prospect.

Soilless culture does not depend on soil. It is to plant vegetables and other crops in a certain cultivation device with nutrient solution, or on a seedbed made of unnatural soil matrix materials such as sand, gravel, vermiculite, perlite, rice husk, slag, rock wool and bagasse with nutrient solution. Because no soil is used, it is called soilless culture. Moreover, soilless culture is also called nutrient solution culture because it does not use ordinary organic fertilizer and inorganic fertilizer, but relies on providing nutrient solution instead of traditional agricultural fertilization technology.

Soilless culture is a major breakthrough in technology because it does not use soil. At the same time, due to the continuous progress of technology, advanced facilities and the application of new matrix materials, soilless culture can completely adjust the temperature, water, light, fertilizer and gas according to the growth and development needs of different crops and implement industrial production. Therefore, soilless culture is a high-tech of modern agriculture and a new technology of modern facility culture.
