摘要： 为了进一步合理高效利用秸秆资源，通过查阅文献和实地调查的方法，在掌握淮北市秸秆资源数量的基础上，估算出2011年淮北市秸秆养分总量。结果表明：2011年淮北市秸秆数量为170.5万t，其中小麦、玉米和大豆三大作物秸秆居多，占秸秆总量的98%以上。所含的总养分为43045.7 t，其中N、P2O5、K2O分别为15511.2 t、4696.8 t、22837.7 t，总价值约1.88亿元。因此，合理利用秸秆的养分资源对于缓解化肥数量的不足，减少农业投入，具有重要的作用。

Abstract: In order to take full advantage of the straw, we estimated the amount of straw and its nutrient contents in Huaibei City in 2011 by literature review and field surveys. The results showed that, the total amount of crop straw was about 1.705 million tons, in which the wheat straw, maize straw and soybean stalks accounted for more than 98% of the total amount of straw. The total nutrients were 43045.7 t and there were 15511.2 t N, 4696.8 t P2O5 and 22837.7 t K2O, the total value is about 188 million yuan. Therefore, straw returning can play an important role in alleviating the shortage of fertilizer and reducing agricultural invest.
