随着农村经济和生产力的发展,农民的生活水平不断提高,商品能源(如煤、油、电、液化气等)在部分经济发达农村的能源消费结构中的比例逐渐增加,从而使该地区大量的农作物秸秆成为废弃物,被堆积在田头、路边或付之一炬;而大部分缺能的地区,秸秆仍作为主要的生活用能,几乎全部葬身于低热效率的普通炉灶内。上述情况不仅使秸秸的物质、能量和养分不能充分发挥,浪费了宝贵的自然资源,而且妨碍交通,污染环境,还造成烧毁树木、禾苗,甚至引起火灾等后果。 With the development of rural economy and productivity, the standard of living of peasants has been continuously raised. The proportion of energy products such as coal, oil, electricity, liquefied gas, etc., in the energy consumption structure of some economically developed rural areas has gradually increased, Of the crop straws become waste, piled up at fields, curbs or at the torch, while in most of the deficit areas, straws are still used as primary household energy and almost all of them are buried in low heat efficiency ordinary stoves. The above conditions not only make it impossible to give full play to the material, energy and nutrients of straw, wasting valuable natural resources, but also hampering traffic and environmental pollution as well as the consequences of burning trees and grasses and even causing fires.
