Many tree seeds, especially conifers, are used to disinfect and germinate the epidermis before sowing in order to reduce the occurrence of disease and increase the rate of germination. The seed disinfection is usually treated with potassium permanganate or other pesticides, the method of sprouting sand storage and warm water soaking. Few have seen a can both disinfection, while promoting germination of the agents and methods. The spring of 1980, I tested 30% concentration of hydrogen peroxide (H_2O_2) processing loblolly pine, pine and Japanese larch seeds, received the above two effects. The spring of 1981, some nursery units in our province to expand the application, the effect is also very good. Now introduced in the next: First, the use of hydrogen peroxide with 30% concentration of bottled pharmaceutical use
