氮和磷肥料配合施用对辐射松生长的影响

Effects of a Combined Application of Nitrogenous and Phosphorus Fertilizers on the Growth of Pinus radiata

  • 摘要: 在岷江上游干旱河谷地区,对1a生辐射松幼林进行氮、磷肥配合施用试验,探讨适宜的施肥量,为干旱河谷地区的辐射松幼林施肥管理提供依据。试验采用随机区组设计方法,进行氮、磷肥配合的不同施肥量试验。结果表明:3个施肥处理与对照比较,处理1和处理2对辐射松幼树的地径、树高的生长有显著提高,处理3仅对辐射松地径有显著提高。在本试验条件下,建议1a生辐射松幼林的施肥量为尿素30g·株-1、过磷酸钙150g·株-1

     

    Abstract: In the arid valley of the upper reaches of the Minjiang river,combined nitrogenous and phosphorus fertilizers were applied on the one-year-old seedlings of Pinus radiate.An appropriate amount of fertilization was explored to provide the basis of fertilization management of yung P.radiate in the arid valley.Different combined fertilizations of nitrogenous and phosphorus were studied based on the randomized blocks design.The results showed that in comparing three treatment groups with control groups,the first and second treatments significantly increased the ground diameter and height of P.radiate.The third treatment merely significantly increased the ground diameter.Under the condition of this study,the recommended fertilization amount was 30 grams of urea and 150 grams of calcium superphosphate per plant for the one-year-old P.radiate.
