秸秆,作为重要的生物质资源,总能量基本和玉米、淀粉的总能量相当。秸秆燃烧值约为标准煤的50%。秸秆蛋白质含量约5%,纤维素含量在30%左右,还含有一定量的钙、磷等矿物质,1吨普通秸秆的营养价值平均与0.25吨粮食的营养价值相当。专家测算,每生产1吨玉米可产2吨秸秆,每生产1吨稻谷和小麦可产1吨秸秆。我国每年可生产农作物秸秆6亿多吨。如全部用来燃烧,可折合约3亿吨标准煤的热值。如全部用作饲料,折算相当于1.5亿吨粮食。经过科学处理,秸秆的营养价值还可大幅度提高。秸秆蕴藏着丰富的能
Straw, as an important biomass resource, has a total energy equivalent to that of corn and starch. Straw burning value of about 50% of standard coal. Straw protein content of about 5%, cellulose content of about 30%, but also contains a certain amount of calcium, phosphorus and other minerals, 1 ton of ordinary straw nutritional value and 0.25 tons of grain on average nutritional value quite. According to experts’ calculations, each ton of corn produced can produce 2 tons of straw, and 1 ton of straw can be produced for every ton of rice and wheat produced. China can produce more than 600 million tons of crop straw annually. If all are used for burning, the calorific value of about 300 million tons of standard coal can be folded. If all used as feed, converted equivalent to 150 million tons of food. After scientific treatment, the nutritional value of straw can also be greatly improved. Straw is rich in energy
