What are the advantages of soilless culture technology?

Soilless culture refers to the cultivation of crops with nutrient solution instead of natural soil. This nutrient solution can replace natural soil to provide water, nutrients, oxygen and temperature for crops, so that crops can grow normally and complete the whole life cycle. Nutrient solution is the key to soilless culture, and different crops need different nutrient solution formulas.

Specifically, inorganic nutrients needed for crop growth are dissolved in water to make a balanced culture solution to cultivate crops; Or pour the culture solution into artificial matrix (such as gravel, peat, sawdust, rice husk, charcoal to stone, perlite, rock wool, etc.). ) to cultivate crops.

Soilless vegetable cultivation in the Netherlands, Japan, Denmark, Israel and other foreign countries has entered the advanced stage of industrial production. The research and application of greenhouse environment regulation, cultivation facilities, working machinery, commodity substrate and special nutrient solution have basically realized industrialization, standardization and commercialization.

Domestic leisure agriculture, rural tourism, rural complexes, characteristic towns and other projects have intensified, and have risen to the national rural revitalization strategy. Eco-restaurants, eco-hotels and eco-parks built by these projects all feature soilless culture. Whether using soilless culture mode for landscaping or providing green ingredients for catering has become a highlight of advocating the new concept of harmonious development between man and nature.

First, the outstanding advantages of soilless culture technology are:

(l) Effectively prevent soil continuous cropping obstacles and soil-borne diseases.

(2) Due to the automation and mechanization of facilities, the man-hours invested are greatly saved.

(3) Not limited by natural conditions.

(4) Save water, fertilizer and labor.

(5) Some crop varieties can greatly increase the yield per unit area.
