对湖南省常德市周家店镇实验林场5种种植密度10年生湿地松的主要化学组分含量进行了统计分析,并对最佳种植密度进行了综合评定。结果表明:(1)种植密度间综纤维素含量变化范围为73.78%～75.56%;1%NaOH抽出物含量变化范围为22.64%～23.84%;种植密度对两者影响均不显著;(2)种植密度间苯醇抽出物含量变化范围为1.54%～2.14%;种植密度对苯醇抽出物含量影响显著;但两两种植密度间的差异程度有很大不同;(3)用于纸浆材最佳的种植密度是1.5m×1.5m。
The main chemical components of five species of 10-year-old Slash pine in the experimental forest farm of Zhoujiadian Town in Changde City, Hunan Province were statistically analyzed, and the optimum planting density was evaluated comprehensively. The results showed that: (1) The content of holocellulose varied from 73.78% to 75.56% and the content of 1% NaOH extract varied from 22.64% to 23.84% The content of m-phenolsanol extract varied from 1.54% to 2.14% in planting densities. The planting densities had a significant effect on the contents of benzene-alcohol extractives, but the differences among the planting densities were very different. (3) Good planting density is 1.5m × 1.5m.
