我国盐碱地主要分布于西北、华北、东北和滨海地区,总面积约0.2～0.3亿hm~2。通常土壤含盐量在0.2%～0.5%时就不利于植物生长了,而我国不少盐碱地的含盐量达0.6%～1.0%。内蒙古自治区有大部分土地便是此种情况。而大家都知道在盐碱地上进行绿化施工时,由于土壤通透性差,土温上升慢,土壤中好气性微生物活动差,养分释放慢,渗透系数低,苗木成活率一般都不高。因此,在施工时采取行之有效的方法及措施,以此来提高苗木的成活率,便成为了盐碱地绿化的关键。那么如何在盐碱地上进行园林绿化呢?我个人认为应从以下几个方面着手: China’s saline-alkali land is mainly distributed in the northwest, north China, northeast and coastal areas, with a total area of ​​about 0.2 ~ 0.3 billion hm ~ 2. Usually soil salt content of 0.2% to 0.5% is not conducive to plant growth, and many saline-alkali land in China reached 0.6% to 1.0%. This is the case with most of the land in the Inner Mongolia Autonomous Region. As we all know, saline-alkali soil in the green construction, due to poor soil permeability, soil temperature rise slow, aerobic soil microorganisms poor activity, slow release of nutrients, low permeability coefficient, seedling survival rates are generally not high. Therefore, taking effective measures and measures during construction to improve the survival rate of seedlings has become the key to the greening of saline land. So how to carry out landscaping in saline land? I personally think that should be from the following aspects:
