What are the new agricultural technologies?

1. Soilless agriculture. Namely soilless culture technology. It uses water as solvent to prepare nutrient solutions with different formulas according to the physiological needs of different crops. Using sand or sawdust as carrier can achieve the production goal of high yield, high quality and high efficiency. At the same time, it has the advantages of low labor intensity, strong ability to resist disasters and adversity, saving labor, water and fertilizer. At present, it is mainly used for planting in special vegetables.

Characteristic agriculture. Refers to the development of agricultural projects with high nutritional value, high consumption value or high added value to meet market demand. For example, developing rare seedlings and famous flowers.

2. Precision agriculture. In recent years, it has become a hot spot in international agricultural research. The core technology is the application of geographic information system (GIS), global positioning system (GPS), remote sensing technology (RS) and computer automatic control system in agriculture. Using these systems, soil and crop management measures can be carefully and accurately adjusted according to the specific situation of each operation in the field, agricultural input can be optimized, and high yield and high benefit can be achieved while protecting agricultural natural resources. At present, developed countries have begun to apply it.

3. Packaging agriculture. In order to adapt to people's purchase of high-quality nutritional products, we also choose new agricultural industrialization projects launched by products. If agricultural products want to win the love of consumers, we should pay more attention to packaging while grasping the quality and scale of products.

4. sightseeing agriculture. With the increase of income, the satisfaction of basic life, the increase of leisure time and the improvement of various material conditions, people have increasingly felt the narrowness and discomfort of urban space. While demanding fresh and safe food, they need to experience the feeling of returning to nature. The rise of sightseeing agriculture can not only meet these requirements, but also play its production functions such as leisure and vacation, ecological protection and rich life. The mutually exclusive and antagonistic relationship between urban and rural areas will become complementary and integrated.
