[目的]为推动柽柳在盐渍土地区的种植与盐渍土的利用提供理论基础。[方法]在东营盐生植物园的盐池进行盆栽和田间耐盐试验,测定柽柳生长50 d后的平均株高、地径、分枝数和死亡率。[结果]柽柳的耐盐能力在25 g/kg左右,耐盐极限为35 g/kg左右;柽柳能够有效地降低土壤表层含盐量,增加土壤有机质含量,提高土壤中N、P、K的含量。[结论]柽柳是一种耐盐能力很强的盐生植物,对滨海盐渍土具有明显的改良作用。
[Objective] The research aimed to provide a theoretical basis for promoting the utilization of Tamarix and Salix in saline soil and the utilization of saline soil. [Method] Potted and field salt tolerance test was carried out in Yanchi of Yanying Botanical Garden in Dongying. The average height, diameter, branch number and mortality of Tamarix spp. [Result] The salt tolerant capacity of Tamarix chinensis was about 25 g / kg and the salt tolerance limit was about 35 g / kg. Tamarix chinensis could effectively reduce the salinity of soil surface, increase the content of soil organic matter and increase the content of N, P and K in soil content. [Conclusion] Tamarix chinensis is a kind of salt-tolerant plant with strong salt-tolerance ability and has a significant improvement on coastal saline soil.
