Studies on Accumulation and Distribution of Dry Matter,Nitrogen,Phosphorus,and Potassium in Rhizome Lotus(Nelumbo nucifera Gaertn)
莲藕干物质和氮磷钾养分的累积与分配研究

Accumulation and distribution of dry matter,nitrogen(N),phosphorus(P),and potassium(K) in rhizome lotus(Nelumbo nucifera Gaertn) were studied by pot experiment for two years.Results showed that,in seeding stages,accumulation of photosynthesis products in leaves was the main growing process.After swollen stem formation,dry matter in leaves,petioles,and rhizomes were distributed to the swollen rhizomes,during which yield formation was the main process.Total dry matter accumulation showed a slow-quick-stable c...
