胡杨是适宜盐碱地生长的乔木树种,发展胡杨人工林是改造利用盐碱地的一个重要途径。但胡杨造林上育苗困难。胡杨枝条扦插一般不能生根,采用根蘖苗造林不但成活率低,而且数量有限。搞好胡杨播种育苗,可以提供大量优质苗木,提高盐碱地胡杨造林质量,实现胡杨速生、丰产。
Populus euphratica is a tree species suitable for the growth of saline-alkali soil. The development of Populus euphratica plantation is an important way to transform and utilize saline-alkali soil. However, poplar nursery afforestation difficulties. Populus cuttings generally can not take root, the use of root tillering afforestation not only low survival rate, but also a limited number. Populus euphratica seedlings do a good job, can provide a large number of high-quality seedlings, improve the quality of Saline-Alpine afforestation, to achieve fast-growing Populus, high yield.
