摘要: 以黑龙江省东北林业大学老山人工林实验站26林班白浆土栽培的红松人工林为试验地,林龄20年,公顷株数为3240株,研究结果表明,矿质元素贮量为502.37 kg·h-1·m-2,平均每年为25.12 kg·h-1·m-2。其中乔木层占总量的81.46%,灌木层占11.17%,草本层占2.56%,凋落层占4.81%。为增加矿质元素含量与贮量,应调整林分结构,促进生长,提高林地生产力。

关键词: 红松人工林, 矿质营养元素, 乔木层, 凋落层

Abstract: The plantations of Pinus koraiensis at the compartment 26 of Laoshan experimental station of Northeast Forestry University were studied. The plantations are 20 years old, and there are 3 240 individual plant per hectare. The results indicate the total storage of nutritive elements is 502.37kg·h-1·m-2. The mean storage is 25.12 kg·h-1·m-2 per annum. The storage of arbor is 81.46%, followed by shrub 11.17%, herb 2.56% and litter 4.81%, respectively. To improve the content and storage of nutritive elements and production, the management of plantations is needed.

Key words: plantation, Pinus koraiensis, mineral nutritive elements, arbor, litter
