Combined forage grass-microbial for remediation of strontium-contaminated soil.

Enrichment plants were screened from six forage grasses in this study to establish a complete combined forage grass-microbial remediation system of strontium-contaminated soil, and microbial groups were added to the screened dominant forage grasses. The occurrence states of strontium in forage grasses were explored by the BCR sequential extraction method. The results showed that the annual removal rate of Sudan grass (Sorghum sudanense (Piper) Stapf.

The evaluation of resistance to Co of lawn plant at seedling stage and its concentration property at adult stage.

In order to evaluate the resistance of lawn plant to Co at germination stage and discuss its concentration property at adult stage, four kinds of lawn plant which have some growth advantages in Co polluted environment were selected as experimental materials in this research. They are tall fescue, timothy grass, inflorescences, and annual ryegrass. The results show that the evaluation of resistance to Co of tall fescue's seed is the highest; the evaluation of resistance to Co of annual ryegrass seed is the lowest.
