扦插育苗是繁殖花木最常应用的主要方法。但采用这种方法常常因受到季节的制约和气候条件的影响,不能周年进行。几年来我们根据温差在扦插上的作用机理,研究了一种冬季利用地热水加热苗床,并相应解决湿度和光照的要求,取得了十分良好的效果。根据对山茶花、杜鹃、米兰、含笑、南洋杉、龙柏、葡萄及多种观叶花卉进行反 Cutting seedling is the most common breeding flowers and trees the main method. However, this method is often affected by seasonal constraints and climatic conditions, can not be conducted annually. In recent years, according to the mechanism of temperature difference on cutting, we studied a winter using geothermal water heating seedbed, and the corresponding humidity and light requirements, and achieved very good results. According to the camellia, rhododendron, Milan, smiling, Araucaria, cypress, grape and a variety of foliage flowers against
