对杉松冷杉试材进行2种药剂(质量分数为0.5%和1.0%)、2种压缩率(5%和10%)、2种压缩方向(径向和弦向)、2种压缩次数(1和4次)的防腐剂辊压浸注和常温常压浸泡处理，测试和研究不同浸注方法对试材载药量、防治效力和真菌感染形态的影响。结果表明：辊压浸注法的载药量高于浸泡法，提高了133.33%～224.24%；前者防治效力比后者提高了25%以上，当辊压浸注工艺为压缩率10%、药剂质量分数1.0%、弦向压缩、压缩4次时，试材的防治效力达到最大值81.97%；可可球二孢真菌在空白样、浸泡法和辊压浸注法试材中的发展顺序呈现由旺盛到纤弱、由充满细胞腔到局部存在的态势，与试材表面和内部的宏观特征表现一致。

This study was conducted to study the effect of impregnation by rollers, under the condition of preservative of mass ratio of 0.5% and 1.0%, both in radial and tangential directions, at the compression rate of 5% and 10%, and at compression times of 1 and 4, on the preservative content, efficiency in controlling fungus and fungal infection form of Needle fir. (AbiesholophyllaMaxim.) specimens. The preservative content was increased by 133.33% to 224.24%, more than 25% for impregnation by rollers compared with normal impregnation. The efficiency in controlling fungus reached the maximum value of 81.97% when the conditions were at compress rate of 10%, mass ratio of preservative of 1.0%, and compression times of 4 in tangential directions.BotryodiplodiatheobromaePat. spread in tracheid cavity from prosperous to weak and from full to sectional, and it was the same with macroscopic characteristics.

可可球二孢(一种蓝变菌)会侵染某些针叶树材的边材部位，菌丝所到之处，会在木材表面形成深浅不一、斑驳陆离的块状蓝色或绿色图案，俗称“蓝变”或“青变”，与健康材对照颜色差异明显[1-2]。在适宜的温湿度条件下，5～7 d蓝变现象就会发生并蔓延；蓝变不仅劣化木材表面的视觉效果，木材力学性能亦有一定程度的降低[3-4]。国家标准中，存在蓝变的锯材被认定为缺陷产品并降低等级[5]。……
