摘要
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。
This paper analyses the chemical components of five different families＇ Populus x euramericana in Shu- nyi, Heze and Langfang three regions. Through testing the chemical components and discussing the pulping and pa- permaking performance, it can provide some theoretical basis on the cultivation of raw material. The results show that the chemical components character of Populus x euramericana conforms to the requirements of raw material for pulping and papermaking. The 6 years old Populus x euramericana cv. ＇ 107＇ growing in Shunyi loam soil has the best chemical components character. The content of holocellulose is 82. 11% and the conotent of lignin is 22. 22%. The 6 years old Populus x euramericana cv. ＇107＇ growing in Shunyi loam soil has the worst chemical com- ponents character. The content of holocellulose is 76.49% and the conotent of lignin is 22.97%. Among the 5 year-old trees, Zhonglin ＇ 2025 ＇ is the best, with the highest content of holocellulose and hemicelluloses. Among the 6 year-old trees, Populus x euramericana cv. ＇107＇ growing in Shunyi loam soil is the best. The light loam soil is most suitable for the Populus x euramericana＇s growth as serving as pulping and papermaking. And the sandy loam soil is the next.
