| 摘 要： | 试验结果表明,在病级不同的樟子松针叶内,无机元素的含量不同。1年生罹病针叶内Fe的含量高于健康林木针叶内铁的含量,2年生针叶内Mn、Cu、K的含量随病级的增高而增加,3年生病叶内Fe的含量比健康林木的高2.7倍,4年生病叶内K、Cu、Mn的含量随病级的增高而增加。

| Abstract: | The results of test show that the content of inorganic element in a different disease index of Pinus sylvestris var. mongolica. The ferrous content in diseased needles of 1 year old is higher than healthy tree. The manganese, copper and potassium content is increased with the increase of disease lndex. The ferrous content of 3 years old diseased needles is 2.7 times higher than healthy tree. The potassium, copper and manganese content of diseased needles is increased with increase of disease index. |
