摘要
对3年生华北落叶松幼苗4种不同处理后各部位铜锌含量和丙二醛含量进行测定分析,结果表明:铜和锌是华北落叶松生长发育所必需的营养元素;用铜和锌处理后的华北落叶松经过高温季节后,叶的丙二醛含量显著降低,说明铜锌元素与树体的抗性有关,可以增强其耐热性。为扩大华北落叶松的人工造林范围提供了重要理论依据。
The content of Copper & Zinc and MDA of various parts of Pinaceae aging 3 years are measured and analyzed with 4 different handlings. It turns out that Copper and Zinc are the essential elements in Pinaceae's growing. After the season of high temperature, the MDA content in Pinaceae leaves with Copper and zinc's intervention is sharply lowered, indicating anti\|attachment between Pinaceae & Copper and Zinc, enhancing its heat\|resistance. So a very important theoretical idea is provided for broadening Pinaceae's coverage.
