Study on the Nutrition Diagnosis of Aleurites montana

The nitrogen (N), phosphorous (P) and potassium (K) nutrition diagnoses were made for Aleurites montana seedlings by means of applying diagnosis and recommendation integrated system (DRIS) with simplex lattice design to formulate scientific fertilization measures, to balance the N, P, K nutrition elements and overall improve the nutrition status of A. montana young plantation. The results showed that the most suitable nutrition proportions for A. montana seedlings were P/N equals 06922, N/K equals 09369, K/P equals 1.5419. It was showed that combination E7 was an ideal fertilization plan, namely, 126g of N fertilizer (urea) per plant, 236g of P fertilizer (calcium superphosphate) per plant, and 138g of K fertilizer (potassium sulfate) for each plant.
