摘  要:
笔者从林木生长、林分产量、木材质量三方面总结了施肥对林木生长效应的影响,从光合速率、叶绿素含量、养分含量、抗逆性等几方面阐述了施肥对林木活力的影响。同时指出施肥对林木效应理论基础研究的重要性,在定性研究的基础上开展定量研究,探求和制订最佳施肥方案,以指导林木施肥。

摘  要:
The theoretical principle for forest fertilization was reviewed,and the effects of forest fertilization on forest growth and physiology were briefly summed up.Firstly,the effects of nitrogen,phosphorus,and potassium on seedling height,collar diameter,its root/shoot ratio,every tissues biomass and total biomass was summarized in plant growth aspect;Secondly,the effects of various fertilization treatments on photosynthetic rate,chlorophyll content and the nutrient content in the body of seedling were generalized.The research advances of forest fertilization vector diagnosis,theoretical basis,diagnosis principle was described.Fertilizing period,fertilizer type,fertilizer value,fertilization quantity was also discussed.
