7种园林植物的耐盐性研究

Studies on Salt Tolerance of 7 Landscape Plants

利用滨海盐碱土配制栽培土壤,采用大棚盆栽试验方法,对7种常见园林绿化植物的生长表现、存活率、高生长、叶绿素含量、相对含水量进行研究的结果表明:连翘、月季和四季桂的耐盐性较差,只能在含盐量不大于2.3 g/kg的土壤中正常生长;其次为金叶女贞,能在含盐量不大于4.6 g/kg的土壤中生长;雪松能在含盐量不大于4.9g/kg的土壤中正常生长;油松能在含盐量不大于5.8 g/kg的土壤中正常生长;爬地柏耐盐性最强,能正常生长于含盐量高达8.7 g/kg的土壤中。

In a pot experiment with the soil from seaside saline soil, this paper studied the growth performance, survival rate, height growth, chlorophyll and relative water content of 7 landscape plants. The result indicated that Forsythia suspensa, Rosa Chinensis and Osmanthgs fiagrans cv. Semperflo are light - degree salt tolerance plants, can grow well in 2.3g/kg salty soil. Ligustrum vicaryi grows well in 4. 6g/kg salty soil. Cedrgs deodara grows well in 4.9g/kg salty soil. Pings tabulaeformis grows well in 5.8g/kg salty soil. Sabina proeumbens is of high salt tolerance, can grow in 8.7g/kg sality soil.
