Analysis of Key Points of Pollution-Free Cultivation Techniques for Bonsai
A. Steiner, chairman of the International Pollution-Free Cultivation Association, clearly defined pollution-free cultivation as nutrient solution cultivation. Plants center on the physiological functions of inorganic nutrient elements. Pollution-free cultivation refers to the use of inorganic nutrient solutions to directly provide plants with the nutrient elements essential for growth, replacing the cultivation method in which soil and organic matter normally provide nutrients to plants. In pollution-free cultivation, the nutrient solution can be sprayed directly onto the root system (aeroponics), or plants can be grown directly in a flowing inorganic nutrient solution (hydroponics), or sterilized microporous inorganic minerals
