我国每年秸秆产量约有6亿吨,居世界首位,其中被利用的数量很少。除少部分用来作肥料、饲料、造纸等原料及燃料外,大部分秸秆被集中焚烧处理,造成严重的大气污染和资源流失。随着科技的进步,秸秆资源将会被研究开发并转化成附加值较高的产品,从而 The annual straw output in our country is about 600 million tons, ranking first in the world, of which the quantity used is very small. Except for a small part used for raw materials and fuels such as fertilizers, feedstuffs and paper-making, most of the stalks are concentrated and incinerated, resulting in serious air pollution and resource loss. With the progress of science and technology, straw resources will be researched and developed and transformed into higher value-added products, thus
