| 摘 要： | 施肥是实现人工林速生丰产的重要手段，合理施肥可以维持土壤养分平衡，提高土壤质量，促进林木生长，同时减少环境负效应。人工林精准施肥是以农业精准施肥为基础形成的营林应用技术体系，主要包括林地管理单元精准划分、林地营养精准诊断、精准施肥及施肥效应精准检验。精准施肥技术在农业上取得了很大进展，但应用到人工林上还有很大的局限性。文中结合农林业施肥研究现状，分析实现人工林精准施肥所需解决的关键问题，提出人工林精准施肥的发展方向。

| Abstract: | Fertilization is an important means to grow fast-growing and high-yield plantation. Proper fertilization can maintain soil nutrients balance, improve soil quality, promote forest growth, and reduce the negative effects on environment. Precision fertilization in plantations is an applied technology regimes for forest silviculture based on precision fertilization in agriculture, which mainly including: 1) accurate partition of forest management units; 2) precised diagnosis of forest nutrition; 3) precised fertilization;4) precised monitoring of fertilization effects. Although it has made great achievements in agriculture, precision fertilization technology is still faced with some limitations in its application in forest management. With an eye to the research on fertilization in agriculture and forestry, this paper analyzes the key problems that need to be solved for the practice of precision fertilization in plantation forests, and propose its future development direction. |
