Abstract
Orychophragmus violaceus, the plant of adaptability to karst, can grow in
limestone soil at low concentrations of nitrogen, phosphorus in karst area. This
paper reports the differences of absorption of nitrogen, phosphorus at low
concentrations of cultivation liquid by Orychophragmus violaceus and Brassica
juncea. In a 10mg/l of concentration of nitrogen, phosphorus respectively,
Orychophragmus violaceus have greater absorption of nitrogen, phosphorus, and
Brassica juncea releases nitrogen, phosphorus of plants into the cultivation
liquid. In a 5mg/l of concentration of nitrogen, phosphorus respectively,
Orychophragmus violaceus absorb phosphorus to a minimum concentration of
0.4 mg/l of cultivation liquid, the minimum concentration of absorption of NH4-
N is 1.8 mg/l. Brassica juncea absorb phosphorus to a minimum concentration of
20.6 mg/l of the cultivation liquid, the minimum concentration of absorption of
NH4-N is 22. 4 mg/l. This shows that Orychophragmus violaceus have the ability
of absorption of nitrogen, phosphorus in lower concentrations and be used as
floating-bed plants on decontamination and administration of eutrophication in
natural bodies of water and sanitary sewage.
Keywords: Orychophragmus violaceus, floating-bed plant, nitrogen,
