耐苏打盐土草坪品种筛选

Selection of turfgrass cultivars based on soda-saline tolerance

通过盆栽和小区试验,测试了紫羊茅、早熟禾10余个品种在不同NaHCO3盐浓度下的相对出苗率、幼苗存活率、根冠比、草坪密度和盖度等相关指标,综合评价了东北地区常用草坪草品种的幼苗期、生育期耐苏打盐土能力,初步确定了适合苏打盐渍土地区种植的耐盐草种。

Through pot experiment and field trial, more than ten cultivars, were tested with the indexes incuding relative germination percentage, survival rate of seedlings, root/top ratio, density and coverage under the condition of different concentration of NaHCO(3. )The capacity of soda-saline tolerance at the stages of seedlings and the other growing stages for the cultivars commonly used in Northeastern China were comprehensively evaluated. The suitable cultivars for soda-saline soil were preliminarily determined.
