摘　　要：文中从干旱胁迫下苗木的生物膜变化、光合作用、蒸腾作用、渗透调节及胁迫激素等方面论述了苗木抗旱机理,并对水分调控、化学调控、生物调控、机械调控等几种苗木抗旱调控技术进行了探讨。In order to adapt to the development of forestry eco-environmental construction, it is imperative to cultivate the drought-resistance seedlings. In this paper, the authors summarize the membrane, photosynthesis, transpiration, osmotic adjustment and stress hormone in the mechanism of drought resistance, and discuss several kinds of control technology of seedlings, such as moisture regulation, chemical regulation, bio-regulation technique and physical control.
