陡峭的山坡水土流失严重,因而土层薄,植被稀少,人们称这样的山为光山秃岭。怎样植树种草,增加这种荒山的植被,改变生态环境,便成为林业科学工作者所关注的问题。为此,日本科学家试验成功了一种“斯特比拉”绿化工作法。此法现在日本全国推广,收效显著。“斯特比拉”是一种较长纤维的专用纸浆。使用前,先把树种、草籽、有机肥料、泥土、水、粘合剂等放入这种纸浆里搅拌均匀,然后通过高压油泵或飞机把它喷洒在山坡陡峭、缺乏植被的荒山上,由于纸浆中较长的纤维杂乱交错,形成了无数小孔洞,这种形如布状的覆盖层,具有较强的保温、保水和固定种子的作用,避免了在播种初期因风吹雨淋而使树种或草种的散失问题发生;同时也避免了种 Steep slopes of serious soil erosion, so thin soil, vegetation is scarce, people call such a mountain Guang Guang bald ridge. How to plant trees and grass, increase the wasteland vegetation, change the ecological environment, has become a forestry scientists concern. To this end, Japanese scientists succeeded in experimenting with a “Stibila” greening law. This law is now promoted throughout Japan, with remarkable results. Strobel is a specialty pulp of longer fibers. Before use, put the tree species, grass seeds, organic fertilizer, soil, water, binders and so on into this pulp and mix well and then spray it on the steep, vegetation-lacking barren hills by means of high pressure oil pump or airplanes The longer fibers in the pulp are messy and intertwined, forming innumerable small holes. This kind of cloth-like cover has the function of strong heat preservation, water retention and fixed seeds, avoiding the wind and rain in the early stage of sowing The loss of tree or grass species occurs; it also avoids species
