With the development of science and technology, soilless cultivation of vegetables has become a trend. Compared with traditional soil cultivation, hydroponic vegetables have many obvious advantages. The advantages of soilless cultivation of vegetables are introduced in detail below.

firstly, it can prevent or reduce the obstacles caused by continuous cropping and continuous cropping soil. For some special crops, they can be planted at any height, continuously produced and listed evenly, so as to improve the land utilization rate. In the process of management, farming, weeding, soil disinfection and other operations are omitted, which greatly saves labor. Because it can meet the needs of crops for temperature, light, moisture and nutrients to the greatest extent, the vegetables produced are not only high in yield and good in quality, but also clean, tender and pollution-free. They are pure green food, which can improve the product grade.

Secondly, because the used nutrient solution can be recycled, the water consumption is very low except that it is absorbed by the roots of vegetables and naturally evaporated, which has the advantage of saving water. At the same time, it promotes agricultural automation. Make full use of and save land resources. The project is a mechanical supporting facility project, which abandons the traditional soil farming mode and can include deserts and factories under any conditions. The construction and production of cement land and other environments can save a lot of valuable cultivated land, labor and water. Automatic circulating water system can save tens of thousands of tons of water resources for the country every year. The project has the comprehensive characteristics of automation and mechanical equipment. All aspects needed for growth are completely divorced from the traditional model of "facing the loess and facing the sky".

Finally, soilless cultivation of vegetables greatly reduces the labor intensity. The crops in this project are planted overhead, far away from soil bacteria, and labor links such as spring ploughing, ploughing, weeding, blowing and sunbathing are omitted. For many years, China has been working hard for pollution-free green food. This project is to meet this demand, advocate the development direction, and create high-quality and high-demand vegetables. In addition, it is not affected by external factors such as geographical location, soil, continuous cropping, fertilization and climate. It has strong cyclical and continuous farming performance. The description of "cheap vegetables hurt farmers" truly explains farmers' helplessness. High production efficiency, good economic benefits, not limited by seasons and varieties.
