我们国家多少年来一直把烧大柴做为生活的主要能源,这是很不科学的,严重地影响了农业生态的良性循环.据有关部门计算,农村生活用能占全国总耗能量的40%以上,而且耗能量中有3/4是生物质能,其中大约80%是消耗在生活用能上.全国农村每年大约要烧掉4亿吨秸秆和柴草.据计算,秸秆燃烧转换率是10%,薪柴也只有15%,这是一个极大的浪费. For many years our country has been burning firewood as the main energy of life, it is very unscientific, seriously affecting the virtuous circle of agricultural ecology.According to relevant departments, rural life energy consumption accounts for more than 40% of the total energy consumption , And 3/4 of the energy consumption is biomass energy, of which about 80% is consumed in domestic energy.About 400 million tons of straw and firewood are burned in rural areas every year.It is calculated that the conversion rate of straw burning is 10% , Firewood is only 15%, this is a great waste.
