摘要:
采用不同浓度的Na2CO3和NaHCO3溶液处理土壤，研究碱性盐对碱蓬种子萌发及幼苗生长状况的影响。结果表明：随着碱性盐浓度的升高，碱蓬种子的成苗率、发芽指数和幼苗生物量均有不同程度降低，在Na+浓度相同的情况下，Na2CO3对碱蓬种子萌发及幼苗生长的抑制作用大于NaHCO3；碱性盐对碱蓬幼苗地下部分胁迫作用大于地上部分胁迫作用；可以将碱蓬引种到Na2CO3浓度小于50 mmol/L和NaHCO3浓度小于100 mmol/L的盐碱地。
Abstract:
In order to study the effects of alkaline salts on the growth of Suaeda glauca Bunge,and provide theoretical foundation for saline-alkali field control.The soil was treated with different concentration of NaHCO3 and Na2CO3,and the germination percentage of Suaeda glauca Bunge, seedling growth and biomass of plantlet were measured.The results showed that its plantlet forming rate decreases with the increase of alkali stress intensity.The relative of plantlet forming rate, germination index, seeding growth were declined.The germination and the growth of seeding were more inhibited by Na2CO3 with the same concentration of Na+.The Suaeda glauca Bunge can be planted to the places where the concentration of NaHCO3 less than 100 mmol/L or Na2CO3 less than 50 mmol/L.
