| 摘 要： | 本文叙述在庇荫条件和光照条件下,红松幼树营养特点的研究。于1984—1986年每隔10—15天定期地测定了红松枝叶的鲜重和干重,并分析了营养元素的含量。结果表明,在庇荫条件下幼树有正常的N、P、K、Cu等元素的含量,有较低的Ca、Fe元素含量和较高的Mn元素含量。由于生长季中期对营养N、P、K等元素感到不足。因此,在营林过程采取相应的技术措施以改善营养状况是加速幼树生长的途径。

| Abstract: | The nutrient characteristics was studied under the condition of shade and sunny from 1984 to 1986. The fresh and the dry weight of twigs-leaves of seedlings were determined every other 10 to 15 days, and the contents of the mineral nutrient element were analysed. The results showed that the seedlings under shade condition had a normal content of N, P, K, and Cu, but had a low content of Ca, Fe, a high content of Mn. In the middle of growth season, seedlings is lack of N, P, and K. Therefore, it was necessary to take some treatment to improve nutrient regime in the practice of sylviculture. |
