Scientific and technological development is the first productive force. Since the reform and opening up, China's agriculture has made considerable progress, in which agricultural science and technology has played a huge role, and the future agriculture is a real high-tech industry. Molecular agriculture, space agriculture and marine agriculture have been implemented and have broad prospects for development.
Soilless cultivation is an important part of high-tech agriculture. The exact meaning of soilless culture is pollution-free, organic humus free and soilless culture. It is the use of nutrient solution to directly provide plants with essential nutrients for their growth and development. In short, soilless cultivation is a new cultivation technology that uses water, sand, vermiculite and other substrates instead of soil and nutrient solution instead of conventional fertilizer instead of soil.Soilless culture can be divided into hydroponics , Aeroponics and substrate culture according to different cultivation media. Now hydroponics is the most common way to grow vegetables.Hydroponics refers to the cultivation method of plant roots directly contacting with nutrient solution without substrate.
What should be paid attention to when planting hydroponic vegetables?
Selection of hydroponics system.
The most common hydroponics systems include hydroponic tower system, nft system and aeroponic system, of which hydroponic tower system and nft system are more suitable for home growers. Different crops are suitable for different planting systems, so it is a very important step to select a suitable hydroponic planting system. The hydroponic tower system is more suitable for leafy vegetables such as lettuce and strawberry, and the aeroponic system is more advantageous for tuberous plants such as beans and potatoes.
Selection of hydroponic sites.
Although the traditional hydroponics method does not occupy too much space, it also has certain limitations. For example, only a certain area of crops can be planted in a specific space. However, such planting methods as hydroponics tower system can be well extended in vertical space, which greatly increases the utilization rate of vertical space.Especially for some indoor growers, they will have a very good experience. The characteristics that can be stacked layer by layer can meet the different needs of growers.
Planters who want to plant a large area can also choose the hydroponics tower system. The efficient use of vertical space can save a large area of horizontal space to meet the purpose of growers to control costs. In addition, the growth cycle of hydroponic vegetables is shorter than that of traditional soil planting. Such efficient planting can greatly help planters to obtain high income.
At present, large-scale hydroponic vegetable cultivation has basically realized automatic and mass cultivation and production. For growers, hydroponic vegetables cover a small area and have high benefits, which greatly reduces labor costs. And because the hydroponics system is higher from the ground, it has put an end to the infection of soil diseases and insects, as well as the pollution of the original heavy metals and other pollutants in the soil.
