苗木施肥技术及其发展趋势

Research on Fertilizer Application Technology for Seedlings and Its Development Trends

立足于苗木施肥的主要理论,从施肥种类、施肥量、施肥时期和施肥方式等方面对苗木施肥技术作了较为系统的阐述,并指出平衡施肥、计算机推荐施肥、研制苗木专用肥、苗木定向培育施肥研究等是今后苗木施肥技术的发展趋势,为制定科学的苗木施肥方案、提高肥料的利用效率、完善林木抚育管理技术等提供理论支撑和科学指导。

As one of important technological means for afforestation,the fertilization for seedlings plays an important role in improving the productivity of forest land and promoting sustainable forestry development. Based on the main theories of seedlings fertilization,this paper made comparatively systematic statement and analysis on fertilization technology for seedlings, including fertilizer type, fertilizer amount applied, application time of fertilizer and modes of fertilizer application,etc. Furthermore,this paper pointed out that,balanced application of fertilizer,computer - aided fertilizer recommendalion,special fertilizer for seedlings and fertilizer application for directed seedling cultivation are the future development trend of seedlings fertilization technology. With these analyses,this paper provides powerful theoretical support and scientific guidance for making scientific fertilization scheme of seedlings,increasing fertilizer use efficiency and improving forest tending and management technology.
