摘　　要：对江西三处嫩毛竹自然制浆过程中的化学成分变化进行了测定，得知在此过程中，嫩竹木素下降50％～70％；半纤维素下降20％～30％；纤维素含量相对提高25％～45％。不同的土法制浆工艺得到不同质量的纸张，其化学成分也有明显差异。同时在实验室模拟了嫩竹发酵过程，对其化学成分变化进行了监测。结果表明，经2．5％石灰液浸泡嫩竹70d（室温），木素含量下降45％左右，半纤维素变化很小；用天然水浸泡嫩竹70d（室温），半纤维素略有下降，木素则几乎没变，先用石灰水预浸3周，再改用自选的芽抱菌液浸泡嫩竹，经1周就达制浆水平，木素下降59％。还对分析方法做了些探索。Chemical analysis of young bamboo and its paper pulp prepared by local native method from three counties Jiangxi proince was reported. The results indicated that the lignin contents of the bamboo paper pulp dropped 50%-70%; hemi-cellulose decreased 70%-80%; cellulose content enhanced 25%-45% in comparison with original young bamboo. Due to different procedures of these three counties they produced different papers and their chemical compositions were different too. The local native process of natural fermentation was repeated in the laboratory in a small scale and its chemical composition was determined. Results indicated that young bamboos soaked for the 7o days in 2. 5 % lime water at room temperature, the content of lignin reduced to 45% ap proximately, hemi-cellulose changed very little. When the young bamboo was in the water with out lime for 7o days at room temperature, hemi-cellulose dropped little, the lignin was almost constant. The young bamboos soaked for three weeks in 2. 5 % lime water and then soaked one week in water containing Bacillus at room tempefrature. The content of lignin reduced. A satisfied pulp was obtained. Three analytical methods were compared and discussed.
