目前世界各国对容器育苗的研究较多,有些国家为了解决高寒和干旱林区的造林成活率和保存率的问题,在本世纪五十年代开始研究容器育苗造林,六十年代先后应用于生产。我国对营养土育苗造林有悠久的历史,早在十二世纪前已有带土造林的生产实践,本世纪五十年代不少地方采用营养砖和营养篮育苗造林,如南方的桉树、松树等树种的容器育苗造林已取得了良好的效果。海南岛对珍贵树种的容器育苗虽也早有研究,但因山区、交通不便、工具落后、生产水平低等原因,发展很慢。从气候来说,由于海南岛干湿季明显,干旱季节有的达半年以上。容器苗具有相当程度的耐干旱能力,所以对容器育苗造林的研究和应用具有更大的意义。
At present, there are many researches on container seedling raising in some countries in the world. In order to solve the problem of afforestation survival rate and preservation rate in some alpine and arid forest regions, some countries started to study container seedling afforestation in the 1950s and applied it to production in the 1960s. China has a long history of afforestation of nutrition soil and seedling. As early as the twelfth century, the practice of afforestation with afforestation has taken place. In many places in the 1950s, nutrition bricks and nutrition baskets were used for nursery afforestation, such as eucalyptus and pine in the south Tree species container afforestation has achieved good results. Hainan Island, precious species of seedling containers have long been studied, but because of mountainous areas, traffic inconvenience, backward tools, low production levels and other reasons, the development is slow. In terms of climate, due to the clear wet and dry seasons in Hainan Island, some have reached more than half a year in the dry season. Container seedlings have a considerable degree of drought tolerance, so the container seedling afforestation research and application of greater significance.
