Abstract
The invention relates to a cutting seedling growing method for improving freezing resistance of pomegranate. The method comprises: (1), low-temperature culturing is carried out and specially-made chemical liquid is sprayed; (2), after a temperature rise, low-temperature culturing is carried out continuously; and (3), transplanting is carried out. According to the method provided by the invention, the operation becomes simple. An experiment demonstrates that with the method, the freezing-resistant capability of the pomegranate seedling can be enhanced substantially. With the conventional low-temperature culturing method, the pomegranate seedling survival rate in winter is only 75.3%; however, with the method provided by the invention, the survival rate of the pomegranate seedlings is 90.0%. Therefore, the effect is obvious; and the method is worth of being popularized.
