Comparative Advantages and Disadvantages of Root Trainers, Dibble Tubes, Plastic Bags and Bare-Rooting

摘要

Traditional methods of growing tree seedlings are often costly and deleterious to plant growth and survival. This compilation of nine illustrated papers presents new technologies for seedling culture currently undergoing successful trials worldwide. Nurseries in developing countries commonly use either the bare root process or plastic bags for growing tree seedlings. With these methods, susceptibility of the seedlings to transplant shock is high. Modern containerization in the form of root trainers and tubes is suggested by the authors as an alternative root culture method. While initially more costly, over the long term it is advantageous in reducing seedling mortality and transportation difficulties.
