摘要:
 为解决宁夏盐碱地生态环境下造林绿化难度大和林木种质资源少的问题。以盐柳1号（Salix psammophila ‘Yanliu Yihao’）和渤海柳2号（Salix matsudana ‘9901’）为材料，测定其在不同土壤盐分含量下苗木生长高度和离地面5 cm处直径的生长变化，探讨盐碱地环境下2品种柳树生长发育的适应性，分析土壤盐分对柳树2个品种生长进程的影响。结果表明：2个品种柳树CK的株高生长和基径生长无差异；在盐碱地上种植，其株高和基径生长均受到很大影响，种植柳树能显著降低土壤表层盐分含量，达到改良盐碱地的作用。综合分析得知，盐柳1号比渤海柳2号抗盐碱能力强，是值得推广的盐碱地栽植优良品种。
Abstract:
 In order to solve the problems of the difficulty in afforestation and lack of proper plant species in saline-alkali land in Ningxia, and to accelerate the pace of development of the local forestry construction, two willow varieties (Salix psammophila ‘Yanliu No. 1’ and S. matsudana ‘9901’) were tested from the aspects of salt resistance and soil improvement. The seedling growing heights and diameters at 2 cm from the ground were measured to investigate the adaptability of the seedlings in saline-alkali soil with different salty levels and the influence of the salt on their growths. The seedling growths of the two varieties were seriously inhibited under moderate to high salty soils. The rates of inhabitation were 52.4% (Yanliu No. 1) and 56.4% (‘9901’), respectively, indicating the salt resistance ability of ‘9901’ was stronger than Yanliu No. 1. The survival rates of two varieties were all above 95%, indicating that both varieties could accomplish their life cycles. The salt contents of the soils (with the depth of 0-20 cm) in which the two willow varieties were planted were significantly reduced, implying that to plant the two willows could achieve the aims of reducing soil salty level. It was concluded that S. psammophila ‘Yanliu No.1’ and S.matsudana ‘9901’ demonstrated strong adaptability to saline soil and planting the two willows could improve soil land. They are worth to be extended.
