摘要:
<正>对从植物纤维原料、浆料及其碱提取液中分离分级木质素一碳水化合物复合体(LCC)方法的研究进展进行了综述。比较了不同方法在得率、纯度、分级及代表性方面的特性。提出适合于不同分离试样分离分级Lcc’的方法。指出今后的分离分级研究中应更注重物理方法、化学方法和生物技术的合理组合利用,建立经济的、适合于工业规模的分离方法,是Lcc分离分级的发展方向之一。
Abstract:
A comparative study on biomass and understorey species diversity during early stage (1~4a) of artificial vegetation (Melia toosendan) in the abandoned lands of Jinshajiang dry-hot valley of Heqing County was reported. The results showed that M. toosendan adapted itself to the environment of dry-hot valley well, grew and shaded well in the early stage. At the same time, it had a large biomass. However, it was very different in the dry weight of biomass of the individual and organs of 4-year old M. toosendan plantation between the south slope and the north slope in dry-hot valley. The biomass was higher on south slope than that on north slope. The biomass of individuals, trunks, branches, roots on south slope were (25.246±0.586), (14.986±0.203), (4.634±0.212), (5.626±0.223)kg respectively. Those on north slope were (16.580±0.206), (8.544±0.087), (2.895±0.067), (5.141±0.074)kg respectively. On the other hand, there were no obvious differences in moisture content of individuals and organs except for the roots in 4-year old M. toosendan plantation between the south slope and the north slope. The study of understorey species diversity showed that M. toosendan improved the growth environment of the abandoned lands, and increased its plant diversity and species richness.
