The current development trend of soilless culture

The above are all reasons that restrict the profitability of soilless cultivation. In fact, from the perspective of the development of soilless cultivation in various countries in the world, they all start with the recycling of gravel cultivation, and the cost is relatively high. The NFT system appeared in the mid-1970s. Various natural and artificial substrates developed at the same time. Europe found rock wool and considered it the best substrate, while Canada used sawdust as the substrate because of the advanced timber industry. The vast majority of substrate cultivation is that the nutrient solution is not recycled, and the cost is low. It has become the main method of soilless cultivation in various countries.

In developed countries such as the Netherlands, Japan, the United States, Denmark, the United Kingdom, France, Germany, and Israel, the production of soilless culture has achieved a high degree of mechanization, automation, electronics, and specialization. The environmental conditions (temperature, humidity, CO2 concentration, ventilation, light) and nutrient solution preparation of the greenhouse are completely controlled by the computer. The production process, including sowing, thinning, transplanting, pest control, harvesting, and grading packaging, is fully automated. , Realizing one-stop factory production, reaching the annual supply of products, high output value, and significant economic benefits; although the initial investment is relatively high, with the gradual maturity of technology and equipment, and the reduction of labor and energy consumption in the later period, the level of income has been Continued growth.

Another trend is mainly in developing countries, mainly based on their national conditions and economic and technical conditions, using simple equipment to obtain materials on site and manual operations. The purpose of developing soilless culture in these countries is to transform the environment, save water and soil resources, and solve the basic needs of people's lives. For China, the main goal of soilless cultivation technology is to study popular soilless cultivation facilities suitable for my country's national conditions in order to reduce investment and production costs. And high-tech applications such as microelectronics, computers, and the Internet of Things are applied to soilless cultivation facilities to realize real-time monitoring of the nutrient solution storage, liquid temperature, pH value, conductivity and supply time. In addition, high-end soilless cultivation can also be carried out for greenhouse parks with conditions. For example, China’s climate and environmental characteristics are more suitable for tomato production. At present, several large modern tomato production greenhouses that are launched use soilless cultivation. Good income has been achieved.
