Agriculture greenhouse hydroponic growing nutrients systems
Substrate cultivation is the largest method in soilless cultivation. It fixes crop in organic or inorganic substrate, by method of dripping or trickle irrigation, and supplies crops nutrient solution. Culture substrate can be filled into a plastic bag, or laid in the cultivation channels or grooves. Substrate culture nutrient solution is not circulating, known as opening system, which can avoid the spread of disease through the circulation of nutrient solution.
Substrate culture has strong buffer ability, so there is no contradiction of moisture, nutrients and O2, and the equipment is more simple than hydroponics and aeroponics, even without the need of power, so less investment, low cost. This culture method is widely used in production.
