硒处理对四叶参氮磷钾吸收积累的影响
Effects of Selenium on the Absorption and Accumulation of Dry Matter,and Nitrogen,Phosphorus and Potassium of Codonopsis lanceolata
摘要
Abstract
Hydroponic culture and pot experiments were conducted to study effects of different selenium(Se) on accumulation of dry matter,and absorption and accumulation of nitrogen(N),phosphorus(P) and potassium(K) of Codonopsis lanceolata.The results showed that seeding and one-year old plant of C.lanceolata presented different responses to Se supply.The accumulation of dry matter,N,P and K of C.lanceolata in seeding increased with Se increasing from 0 to 1.5 mg/kg,with the best being 1.5 mg/kg,and no significant difference between 2.0 mg/kg and control,whereas 1.0 mg/kg was the optimal in pot experiment.It is concluded that different culture modes affected accumulation of dry matter,and absorption and accumulation of N,P and K of C.lanceolata.Under this experimental condition,1.0 mg/kg was the optimum in pot experiment,which could be used as recommendation for field culture.关键词
