摘要: 干旱是阻碍全球林业发展的一个重要因素,故各国对树木抗旱性的研究非常重视.在育苗阶段,通过不同栽培处理,如水分胁迫、施肥、生长抑制剂、菌根菌、光周期等,研究苗木对干旱的形态适应性和生理适应性,为培育抗旱树种提供了理论依据,对增强苗木抗旱性,提高造林成活率有重要意义
英文摘要: Abstract Plant depends on its morphorlogical and physiological characteristics to adapt to drought. Nursery stage is crucial for tree seedlings to become drought resistant through different treatments such as water stress, fertilization, growth regulators, mycorhiza or changing photoperiod. Establishment of plantation will be much improved on dry site through nursery techniques. The research methodology and silviculture are reviewed for study of plant resistance to drought.
