pot plant
8.The results showed that optimum combinations were black locust with E2, bunge ash or Babylon weeping willow with E4. Pot and field experiment showed that degradation effect were better when plant inoculated with 4 species of ECM fungi together than with one or two species, and better in non-fertilizing treatment.
10.The measures to reduce the contamination of l37Cs to plant and 137Cs transfer from soil to plant are evaluated by pot and field plot experiment. The measures include the application of salt such as potassium, sodium, ammonium, phosphate and lime, plant ash, trown coal, rooting, biological puritication and uprooting.
