Hydroponics system refers to a new cultivation method which uses nutrient solution instead of soil matrix, which can effectively provide the material needed for the growth of farm objects, and provide a suitable environmental condition for the growth of crops, so as to improve the production speed and growth of crops.
1. The development status of soilless cultivation in China have been used very early in China, such as raw bean sprouts, potted narcissus etc. In recent years, China's soilless cultivation technology has developed rapidly, soilless cultivation area is gradually increasing, mainly used in the production of vegetables and flowers. The main body of hydroponics is nutrient liquid membrane technology, cultivated crops through the root system in the shallow flow of fertilizer absorption, through the branches in the upper absorption of oxygen, so as to solve the contradiction between oxygen absorption and root water absorption.
2. Thought on the development of soilless cultivation in China the development prospect of soilless cultivation what is objective, but its requirements for technology and funds should be studied experimentally according to the actual situation of the local area, and then find out a suitable soilless cultivation route for the development of our country.
2.1 The development and application of soilless cultivation techniques should be adapted to local conditions because the natural resources and soilless cultivation techniques are different everywhere, so different production methods and management models are used.
2.2 Strengthening the development of stereoscopic cultivation model for the sustainable development of China's economy, it is necessary to make rational use of limited resources to maintain economic development by improving the production efficiency of land and expanding the space of new agricultural development.
2.3 Reduce production costs, increase economic efficiency through innovative technology, reduce costs, increase crop yields, achieve the effect of half the effort
2.4 The development of organic ecological soilless cultivation technology inorganic energy-consuming soilless cultivation, not only high energy consumption, environmental pollution, but also the production of crop nitrate content exceeded the standard. Organic ecological soilless cultivation is in line with the current development needs of ecological agriculture.
3. Conclusion
China's soilless cultivation technology has been in the experimental stage into the stage of production and application, its technology is also increasingly perfect, the speed of development will be further accelerated, it has been proved that the modernization of soilless cultivation, the faster the development of automated procedures, the greater the production benefits obtained. Soilless cultivation technology can promote the rapid development of agriculture, horticulture and flower production, therefore, soilless cultivation technology has broad prospects for development.
