作为秸秆生产大国,我国耕地和淡水资源短缺,农作物秸秆,尤其是玉米秸秆、棉花秸秆、小麦秸秆和稻壳等极为珍贵,其总量和玉米、淀粉的总能量相当,其燃烧值约为标准煤的50%,每生产1t玉米可生产2t秸秆,可代替热值相当煤炭或液化气。如果将我国每年产生的农作物秸秆全部用来燃烧,可折合约3亿吨标准煤的热值。充分利用农作物秸秆,实现秸秆回收利用,无疑是一件利国利民的
As a large straw producer, China has a shortage of cultivated land and freshwater resources. Crop straws, especially corn stalks, cotton stalks, wheat stalks and rice husks, are extremely valuable. The total amount of crop straws and cornstarch are equivalent to those of corn and starch, 50% of coal, producing 1t of corn per day produces 2 tons of straw, which can replace coal or liquefied petroleum gas with calorific value. If all the crop stalks produced in our country are used for burning, the calorific value of about 300 million tons of standard coal can be converted. Make full use of crop stalks to achieve straw recycling, no doubt a benefit the country
