摘　　要：在微型薯生产中,定期的喷施一些营养元素以用来补充其营养。蛭石作为基质在反复使用以后,蛭石中的养分含量就会失衡,严重时影响脱毒苗的生长。研究认为,蛭石使用2a后建议进行更换。In order to supply nutrient we often spray some nutrient elements during the produeting mini-potato . However, vermiculite is used again and again, we have found the nutrient content content lose the balance and seriously effect growth of virus-free seedling. The study results considered, vermiculite would be changed afrer two years used.
