日本落叶松AS-AQ浆和KP浆的漂白特性比较

Comparison of the characteristics of alkaline - anthraquinone pulp and kraft pulp of Japanese larch

日本落叶松（Larixkaempferi）是我国主要针叶纸浆用材树种。

Japanese Larch clones ( Larix kaempferi ) is one of the most important coniferous species for pulpwood in China .

原浆的卡伯值高对保持日本落叶松KP浆的抗张强度和裂断长有利，而对耐折度和撕裂指数不利。

If the pulp has high Kappa value , its tensile strength and breaking length are better , but its folder endurance and tearing index are less .

利用日本落叶松种子园半同胞家系，按田间设计要求建立家系对比试验林，林龄10a生通过鉴定。

Larix kaempferi seed orchard half sib-family contrast test-woodland was built according to the field design , which being studied after 10 years .

日本落叶松（Larixkaempferi）自19世纪末引入我国以来一直倍受林业研究者的关注和重视。

Larix Kaempferi is a kind of tree which the forest experts draw attention to since it was introduced into China at the end of 19 century .

在此条件下蒸煮可制得日本落叶松AS-AQ浆的卡伯值在35左右，粗浆得率保持在47%以上。

Under this pulping condition , we can get a pulp with about 35 kappa number and above 47 % yield of pulp .

为深入了解日本落叶松的纸浆物理性能，该文以日本落叶松ASAQ浆为原料，对纸浆的漂白特性进行了系统研究，并与KP浆的漂白特性进行了比较。

This paper systematically investigated bleaching properties of AS-AQ pulp of Japanese larch and compared the differences between AS-AQ pulp and KP pulp in order to understand physical properties of Japanese larch pulp .

采用Richards生长模型为日本落叶松人工林生长的基本模型，建立了整体生长和收获预估模型、林分自然稀疏模型，研制了不同造林密度的日本落叶松人工林自然生长过程表。

Using Richards growth model as the basis , stand growth and harvest forecast and self-thinning model were established for Larix kaempferi pulp plantation . Natural growth table of forest for different density were also built .

研究了高、中柱式、矮台式整形修剪方法对不同年龄（2～10a生）日本落叶松采穗母株生长、产穗量、插穗生根（无激素处理）及2a生扦插苗生长的影响。

Effects of Larix kaempferi pruned in different types on growth and cutting production of ortets , cutting rooting ability and growth of 2-year-old rooted cuttings were compared at different ages ( from 2-year-old to 10-year-old ) of ortets .

在教育实践中，应注意把两者有机结合起来。日本落叶松（Larixkaempferi）自19世纪末引入我国以来一直倍受林业研究者的关注和重视。

In school 's education practice , we should draw attention to link them organically . Larix Kaempferi is a kind of tree which the forest experts draw attention to since it was introduced into China at the end of 19 century .
