牛粪是青藏高原上的主要燃料,数千年来广大牧区都一直用它生火烧茶、煮饭、取暖。因而牛粪曾被人誉为“高原圣火”、“高原之光”。 在茫茫无垠的雪域高原上,凡是有人的地方就有牛粪火。走进牧民的帐篷,到处都可以看到凉晒的牛粪和垒得整整齐齐的牛粪堆、牛粪墙。高原上气温低,牦牛以牧草为食,因而牛粪经风干或凉晒之后,燃烧起来如木柴一样没有异味,易燃耐久。 Cattle dung, the main fuel on the Tibetan Plateau, has been used for thousands of years to ignite tea, cook rice and warm it. Thus cow dung has been hailed as “Plateau Torch,” “Plateau Light.” In the boundless snow-covered plateau, cow dung fire is found wherever there are people. Into the herdsmen’s tent, you can see the cool sun cow dunnuts and neatly stacked cow dunghuai, cow dung wall. Low temperature on the plateau, yak to pasture for food, so cow dung air-dried or cool, like burning firewood as no smell, flammable and durable.
