对黄河三角洲盐渍土中耐盐植物生长及脱盐效果进行了研究。在植物种植之前,对种植区土壤的理化指标进行了测定,并进行了漫灌淋盐,降低土壤含盐量。选定了5种耐盐景观植物,柽柳、盐地碱蓬、千屈菜、芙蓉葵和绒毛白蜡在试验区进行了种植,对生长指标进行了监测和脱盐效果研究。结果表明,各植物在盐渍土中生长正常,且景观效果好。各植物脱盐效果约4.57%~6.32%,盐地碱蓬脱盐效果最好。
Salt-tolerant plant growth and desalination in saline soils of the Yellow River Delta were studied. Before the plant was planted, the physical and chemical indexes of the soil in the planting area were measured, and the flooding and dripping salt was carried out to reduce the salinity of the soil. Five species of salt tolerant landscape plants were selected. Tamarix, Saline soda, Lythrum officinale, Hibiscus mairei and Flos white wax were planted in the experimental area, and the growth indicators were monitored and desalination effects were studied. The results showed that all plants grow normally in saline soil and the landscape effect is good. Desalination effect of about 4.57% ~ 6.32% of plants, the best salt desalination effect.
