实验以野生沙枣为研究对象,在根系附近采集实验组土样,在周围裸露土地上采集对照组土样。通过实验组与对照组的各项指标对照表明,在盐渍土上种植沙枣,不但可增加土壤中的含水量,而且可增加土壤中的空气体积和有机质含量,提高土壤中的K含量,降低土壤中pH值。沙枣对滨海盐渍土有着很好的改良效果和一定的经济效益。
In the experiment, the wild dates were taken as the research object, and the soil samples of the experimental group were collected near the root system and the soil samples of the control group were collected on the bare soil around. Comparison of the indicators of the experimental group and the control group shows that the cultivation of jujube on saline soil can not only increase the water content in the soil but also increase the air volume and organic matter content in the soil and increase the K content in the soil, Reduce the pH in the soil. Ears jujube on the coastal saline soil has a very good improvement effect and some economic benefits.
