摘要:
文中所述的物理型缓控释肥料主要包括包膜缓控释肥料及用木材剩余物制作壳体的缓控释肥料两种。主要介绍了包膜缓控释肥料的研究现状，阐述了木材剩余物缓控释肥料壳体的研究内容、依据及该研究的社会意义。概述了物理型缓控释肥料在林业领域上的应用，近年来物理型缓控释肥料存在的问题及发展趋势，以期为缓控释肥料的进一步研究提供参考，为该研究实现产业化发展提供科学指导。
Physical type slow/controlled release fertilizers described in the article mainly consisted of coated slow/controlled release fertilizers and slow/controlled release fertilizers which were made by wood residue. This article introduced research status of coated slow/controlled release fertilizers. Research contents and basis of wood residue slow/controlled release fertilizers were stated and social meaning of this study was also discussed. Application in forestry area, presence problems and developing trend in recent years of physical type slow/controlled release fertilizers were summarized. This offered reference for further study on slow/controlled release fertilizers, and it provided scientific guidance for this study to achieve industrialization development.
