Answer 2

Answer:

Soilless culture refers to a cultivation method in which water, grass charcoal, forest mulch, vermiculite and other media are used as the substrate for plant roots to fix plants, and plant roots can directly contact nutrient solutions. The composition of the nutrient solution in soilless culture is easy to control and can be adjusted at any time. In places with suitable sunlight and temperature but no soil, such as deserts, beaches, and deserted islands, it can be carried out as long as there is a certain amount of fresh water supply. Soilless culture can be divided into hydroponic culture, fog (air) culture and substrate culture according to different culture media. Hydroponics refers to the cultivation method in which the roots of plants are directly in contact with nutrient solution without using a substrate. The earliest hydroponic culture was to immerse plant roots in a nutrient solution to grow. This method will cause hypoxia and cause root death in severe cases. The hydroponic method of nutrient liquid film method is often used, even if a thin layer of nutrient liquid continuously circulates through the roots of the crop, it not only ensures the continuous supply of water and nutrients to the crop, but also the constant supply of fresh oxygen to the roots.
