胡杨是我国荒漠地区唯一的乔木树种,在维护干旱地区的生态平衡、提供用材、燃料和饲料等方面,都具有重要作用。由于胡杨林大面积减少,不少地区生态条件恶化,维护、恢复和发展胡杨林是当务之急,而正确评价其土壤条件是进行这一工作的基础。研究表明,胡杨抗旱但非旱生,耐涝但非沼生,耐盐但非盐生,抗风沙但非沙生(树种)。胡杨的恢复和发展要围绕土壤条件特别是水分和盐分条件因地制宜地采取相应的措施,如封滩育林、挖桩更新、断根萌蘖、头木作业、退耕还林、引洪灌溉和人工造林等。胡杨抗盐耐涝还可作为干旱地区盐碱地护田林的主要造林树种。
Populus euphratica is the only arbor species in the desert area of our country and plays an important role in maintaining the ecological balance in arid areas and providing materials, fuel and feed. Due to the large area of Populus euphratica forest is reduced, the ecological conditions in many areas are deteriorating. It is imperative to maintain, recover and develop Populus euphratica forest. The correct evaluation of the soil conditions is the basis of this work. Studies have shown that Populus euphratica drought but non-xerophytic, waterlogging but not marsh, salt but not salty, anti-winds but non-desert sand (tree species). Populus euphratica restoration and development should focus on soil conditions, especially water and salt conditions to take appropriate measures to local conditions, such as beach closure, digging pile renewal, root sprouting, cut wood, returning farmland to forest, flood diversion and artificial afforestation . Populus salina salt-tolerant waterlogging can also be used as the main afforestation tree species in the saline-alkali soil protection in arid areas.
