研究红花+杜梨、胡卢巴+沙枣、红花+沙枣、红花等4种种植方式下土壤的全盐、Na+、Cl-、SO2-4含量及pH值的情况。结果表明,木本植物沙枣、杜梨与草本植物红花、胡卢巴间作可以有效降低0~50 cm土壤全盐含量、pH值,降低Na+、SO2-4和Cl-含量。红花+杜梨间作和红花处理改良滨海盐渍土效果较好。
The contents of total salt, Na +, Cl-, SO2-4 and pH value in soil were studied under four planting methods: safflower + pear, jujube + date, safflower + date and safflower. The results showed that the total salt content, pH value and Na +, SO2-4 and Cl- contents of 0-50 cm soil could be effectively reduced by intercropping with the safflower and herbaceous safflower plants and safflower or herbivorous plants. Safflower + pear intercropping and safflower treatment to improve the coastal saline soil better.
