通过对龙池杜鹃属的31个种32个样品的研究发现,杜鹃叶片氮含量为1.1097%(大白杜鹃)~2.1412%(紫花杜鹃),磷含量为0.0910%(露珠杜鹃)~0.1693%(美容杜鹃),N/P为8.0958(云锦杜鹃)~17.9160(云南杜鹃),LMA为0.0716 mg/mm2(云南杜鹃)~0.2339 mg/mm2(云锦杜鹃)。N/P与LMA呈现显著的负相关(R2=0.5764,P<0.01),表明杜鹃叶片越厚,叶片N/P越低,植物相对生长速率越快,对生态环境适应性越强。
According to the study on 32 species of 31 species of Rhododendron in Longchi, the nitrogen content in the leaves of Rhododendron was 1.1097% (Rhododendron rhododendron) ~ 2.1412% (Rhododendron infinites), and the phosphorus content was 0.0910% (Rhododendron dendrobium) ~ 0.1693% Rhododendron), N / P was 8.0958 (Rhododendron fortunei) ~ 17.9160 (Rhododendron yunnanensis), LMA was 0.0716 mg / mm2 (Rhododendron yunnanensis) ~ 0.2339 mg / mm2 (Rhododendron fortunei). N / P and LMA showed a significant negative correlation (R2 = 0.5764, P <0.01), indicating that the thicker the rhododendron leaves, the lower the N / P of the leaves, the faster the relative growth rate of the plants and the stronger the adaptability to the ecological environment.
