本文对顺义、菏泽、廊坊不同土质的5年生和6年生5个不同品系欧美杨进行了化学组成分析。结果表明各品系欧美杨的化学成分均比较适用于制浆造纸,其中顺义壤土6年生欧美杨107材性最好,廊坊砂土的6年生欧美杨材性最差,综纤维素含量仅为76.49%,木素含量偏高,为22.97%。对5年生欧美杨,顺义壤土5年生2025材性最好,综纤维素含量和聚戊糖含量都达到最高,分别为81.77%和23.97%;6年生欧美杨中,顺义壤土欧美杨107的材性最好,综纤维素含量最高,为82.11%,聚戊糖含量为22.63%,木素含量为22.22%。顺义壤土最适合欧美杨生长,荷泽砂壤土次之。
In this paper, we analyzed the chemical compositions of five different strains of 5-year-old and 6-year-old European and American poplars with different soil quality in Shunyi, Heze and Langfang. The results showed that the chemical constituents of Populus euphratica were more suitable for pulping and papermaking. Among them, 6-year-old Populus tomentosa seedlings of Shunyi loam soil had the best material properties, while Langfang sandy soil had the worst 6-year-old Populus euphratica and the holocellulose content of 76.49 %, Lignin content is high, 22.97%. The 5-year-old European and American poplar, Shunyi loam 5-year-old 2025 the best material, holocellulose content and pentose content have reached the highest, respectively 81.77% and 23.97%; 6-year-old Europe and the United States Yangzhong, The best sex, holocellulose content was the highest, 82.11%, pentosan content of 22.63%, lignin content of 22.22%. Shunyi loam most suitable for the growth of Europe and the United States, Heze sandy loam times.
