苗木稳态营养加载技术研究进展

苗木稳态营养加载技术目前已成为欧洲和北美苗木施肥的主要技术,广泛运用于栎属、云杉属、松属等欧美地区主要造林树种。我国于1988年利用稳态营养加载技术对兰考泡桐、刺槐、杉木、湿地松等树种的苗木进行了初步经营,21世纪以来该方面研究基本处于停滞状态。笔者从稳态营养加载技术的理念、稳态营养加载参数确定技术、稳态营养加载在容器苗应用、稳态营养加载与树种敏感性、稳态营养加载与秋季施肥、缓释肥、菌根及苗木质量等方面,对国际上近30年的相关研究成果进行综述,并结合当今研究热点,对该领域研究前景进行了展望。

Study of techniques for steady-state nutrition supply of seedlings

The techniques of the steady-state nutrition supply(SSNS) for seedlings originated from the 80 years of 20th century.Based on the more than 30 years studies,the techniques have been a dominant fertilization method and thus used widely in the Europe and America for the culture of the seedlings of the main forestation trees,including Quercus,Picea,and Pinus.By using of the techniques from 1988,preliminary studies were conducted on the seedling,such as Paulow elongata,Robinia pseudoacacia,Cunninghamia lanceolata and Pinus elliottii.However,the relative studies have been hampered for some reason since the 21th century in China.In this paper,the studies in the about 30 years were analyzed,including the theory and the parameters` calculation of the SSNS,the application in the containerized seedlings,adaptive in the tree species,the relation between SSNS and late-season fertilization,slow-release fertilization,mycorrhization,and seedling quality.In addition,the future in the study was prospected.
