由于在露天环境中遭遇生物腐蚀,竹秆的持久性差,所以需要采取化学手段增强其耐力。但是它的解剖构造使化学物质难以像木材那样容易进入竹材。竹秆的外部由其表皮保护防水,不像木材那样有径向渗透的途径。而其内部腔隙也有保护性纤维。化学物质的主要渗透途径位于竹秆根部微管束的后生木质部。这些渗透途径分布于横剖面,很不均匀,且少,只占总面积的8~10%,而且在通过竹节时改变方向。由于在采伐时砍伤竹秆,通向导管的细胞腔被堵塞,渗透途径也受影响。周围的薄壁细胞是竹秆组织的主要部分,它们通过微小的纹孔互相连接,只能通过弥散进入。它们所含的淀粉是昆虫和某些真菌的食品。对纤维的保护也有赖于弥散。用化学物质进行保护,对于新鲜的含水量高的竹秆效果最好。就像简单的根部处理,或技术性较强的细胞液改善。新鲜竹秆的薄壁组织和纤维也能通过垂直弥散的方法得到保护。如进行滴渍和浸渍工作,最好在竹材含水分时劈开,因为薄壁组织容易接受弥散。技术措施如竹秆的水分储存和熏蒸的过程,与竹秆的自然结构,尤其是薄壁组织有关。
Due to the biological corrosion in the open air, the persistence of bamboo stalks is poor, so chemical means are needed to enhance their endurance. But its anatomical structure makes it harder for chemicals to enter bamboo as easily as wood. The exterior of the bamboo stalk is protected by its epidermis, unlike the wood that provides radial penetration. And its internal lacuna also has protective fibers. The main chemical penetration pathways are located in the posterior xylem of tuberous root bundle. These infiltration paths are distributed across the cross-section, are very uneven, and scarce, accounting for only 8-10% of the total area, and change direction as they pass through the bamboo. Due to chopping of culms during harvesting, the cell lumen leading to the catheter is blocked and the infiltration pathway is also affected. The surrounding parenchyma cells are the main part of the bamboo stalk and they are interconnected by tiny pits that can only enter by diffusion. The starch they contain is a food for insects and certain fungi. The protection of fibers also depends on dispersion. Protected with chemicals, for the best high moisture content of bamboo stalks best. Like a simple root treatment, or more technical cell fluid improvement. The parenchyma and fibers of fresh bamboo stalks can also be protected by vertical dispersion. Such as dropping and dipping work, it is best to split the bamboo moisture, because the easy-to-accept dispersion of parenchyma. Technical measures such as bamboo stalks moisture storage and fumigation process, and the natural structure of bamboo stalks, especially parenchyma.
