千年桐苗木营养诊断研究

Study on the Nutrition Diagnosis of Aleurites montana

    摘要
  • 摘要: 为科学地制定施肥措施，全面改善千年桐幼林的营养状态，使主要养分元素N、P、K达到理想的平衡状态，采用单形格子设计，应用诊断施肥综合法（DRIS）对千年桐苗木N、P、K 3种元素进行营养诊断，结果表明：苗木养分含量适宜的P/N为06922、N/K为09369、K/P为1.5419；处理E7为较理想的施肥方案，即氮肥（尿素）126g/株，磷肥（过磷酸钙）236g/株，钾肥（硫酸钾）138g/株。

     

    Abstract: 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.
