| 主权项 | 1. A method for preparing a growth substrate for plants comprising polylactic acid foam, the method comprising the steps of: i) providing particulate expandable polylactic acid; ii) mixing the particulate expandable polylactic acid of step i) with water-soluble additives; iii) placing the mixture obtained in step ii) under specific temperature and pressure conditions, so that particulate polylactic acid foam is obtained; and iv) adjusting the cell structure of the particulate polylactic acid foam by washing out the water-soluble additives. | ||
