林木苗期营养诊断与施肥研究对于指导培育壮苗、提高苗木质量和造林成活率至关重要。文中详细介绍了形态分析、植物组织分析、生理生化分析等几种主要的林木营养诊断方法在国内外林木苗期诊断试验中的应用情况,从施肥方式、施肥量以及元素配比等方面对国内外林木苗期施肥研究进行总结,并展望未来林木苗期营养诊断与施肥研究的发展方向。
Research on nutrition diagnosis and fertilization at seedling stage of forest trees is very important to guide the cultivation of strong seedlings, improve seedling quality and afforestation survival rate. In this paper, the application of several main methods of forest nutrition diagnosis, including morphological analysis, plant tissue analysis and physiological and biochemical analysis, to forest seedling diagnosis at home and abroad are introduced in detail. The effects of fertilization mode, The research on the fertilization of the outer forest seedling stage is summarized, and the future development direction of the nutrition diagnosis and fertilization research on the forest seedling stage is forecasted.
