1, substrate cultivation, the principle of substrate cultivation is to use some culture media to fix the roots of plants, and then use nutrient solution to supply nutrients needed for plant growth. Perennial substrates include vermiculite, perlite, coconut bran, peat and so on. Therefore, during the planting process, we should pay attention to regular disinfection of these media to prevent bacteria from breeding and cause diseases for too long.

2. Chemical synthetic substrate cultivation: In addition to natural culture medium, chemical synthetic substrate cultivation technology can also be used for substrate cultivation. Urea-formaldehyde, polyurethane, phenolic aldehyde, etc. Can be use as a substrate raw material. When the substrate is sterilized, it can be put into a cabinet or box and sealed with steam through a ventilation pipe at 70 ~ 90℃ 15 ~ 30 minutes.

3. Hydroponics. Hydroponics can be divided into dynamic hydroponics and static hydroponics. Static hydroponics is a relatively simple cultivation method, and plants can be raised in clean water. Dynamic hydroponics requires the use of pipes, cultivation tanks, nutrient solution pools and other items, which has a high degree of automation and is a relatively simple cultivation method.
