摘要
在内蒙古河套平原碱化盐土上对穆子等7种牧草进行的试种表明,苗期都有一定的耐盐能力,其中穆子、碱茅的耐盐性最强。穆子在0～10cm表层土壤含盐1.42％时,出苗率为62％;碱茅在含盐1.70％时,出苗率为55％;保苗率均在95％以上。种植时要进行种子处理和改进播种技术。
The author introduced seven grasses (Billin-Dollar grass et al.) on the alkaline soil in Hetao plain of Inner Mongolia.The results showed that all of seven grasses had certain tolerance to saline alkaline in seedling stage.Howover,Billion-Dollar grass and Dahurian wildrye had the strongest saline tolerance.When the salt content was 1.42% in the soil surface of 0 to 10cm.depth, the emergence rate of Billion-Dollar grass was 62%; when salt content wasl.7% in the emergence soil surface of 0 to 10cm depth, themergence rate of Dahurian wildrye was 55%, the rate of protecting young plants was above 95%, It's necessary to treet seeds and improve sowing technics when planted.
