- Description of technology and equipment:
In aeroponics method, plants are fixed in the air and the nutrient fluid is frost sprayed directly on the roots. Because the roots are fixed in the air, therefore, it should be maximize " breathing ", plus the mist of nutrient temperature should be lower than the body and the environment ( due to evaporation effects ). So, it will develop more quickly than other methods . The nutrient fluid is filtered and the excess will be collected for re- use, thus saving a large amount of water and nutrients .
In the windy environment as the Truong Sa , if they want to use aeroponic method, the greenhouse is needed to prevent the wind and evaporative losses and the investment costs is about 30 millions VND for 25m2 greenhouse, if it is extended to 100 m2 , it only costs $ 100 million VND. In favorable climates, using truss pergola will reduced cost significantly. People in urban areas are easily applied this method if they have terrace . The nutrient fluid is sprayed on the roots containing substances similar to the soil and people can buy easily in the agriculture service place. Through experiment with all kinds of broccoli , tomatoes , potatoes , spinach ... using aeroponic method in greenhouse , the research team obtained results that normal planting in the same square meter of land, the aeroponic method is 2 time higher production , 2.5 higher growth and 70% water saving . Therefore, the average profit is always more than doubled higher thank traditional method and also time saving for more farming. It is even higher profit for planting under the pergola instead of the greenhouse.
