| 摘 要： | 通过人工气候室和玻璃温室条件下的盆栽试验,研究了碱蓬、灰绿藜、小藜、马齿苋和大豆5种沿海地区常见农田植物对土壤盐渍化程度的指示作用.结果表明,这5种植物的存活率和株高增长率与土壤含盐量存在显著的响应关系.通过复合观察这5种植物的生长性状,可形成一套直观简便的土壤盐渍化程度植物指示体系,用于判别农田土壤含盐量小于0.27%、0.27%～0.66%、0.66%～0.78%、0.78%～0.99%、0.99%～1.77%和大于1.77%的6种不同土壤含盐量范围.

| Abstract: | The indication of soil salinity by 5 species of farmland common plants in coastal region of China was studied through potted cultivation in the climate chamber and glass-greenhouse,such as Suaeda heteroptera Kitag,Chenopodium glaucum Linn.,Chenopodium serotinum Linn.,Portulaca oleracea Linn.and Glycine max Linn.The results showed that there were obviously response relations between plant height growth rate and survival rate with soil salinity.A set of simple and visual plant instruction system was set up,wh... |
