中文摘要	农作物秸秆是农区重要的饲草料，对秸秆营养品质进行分析评价，有利于提高秸秆的利用效率。应用化学分析法对玉米、小麦、裸燕麦、谷子、糜子、高粱6种作物秸秆粗蛋白、粗脂肪、粗纤维和钙、铁和磷等营养成分进行检测。结果表明，6种作物秸秆中，玉米秸秆的粗蛋白含量最高(77.2 g/kg)；糜子秸秆的粗脂肪含量最高(21.7 g/kg)；粗纤维含量最低(312.8 g/kg)；谷子秸秆的钙和铁含量最高(分别为4.76 g/kg和598.66 mg/kg)；玉米秸秆的磷含量最高(0.84 g/kg)。采用有机物质消化率对6种作物秸秆营养价值进行评价，排序为糜子(52.22%)>玉米(48.07%)>高粱(44.86%)>谷子(41. 28%)>小麦(30.91%)>燕麦 (29.41%)。
英文摘要	Crop residual straw is important fodder in the arid agricultural area. Analysis and evaluation on nutritive composition are helpful for improving the feed efficiency. In this paper, the straw nutritive compositions of six kinds of crops residual straw were tested. The result showed that crude protein content of maize stalk was the highest, being 77.2 g/kg; crude fat content of proso millet straw was the highest,being 21.7 g/kg; and crude fiber content of proso millet staw was the lowest, being 312.8 g/kg. The highest content of Ca and Fe were presented in foxtail millet residual straw (4.76 g/kg and 598.66 mg/kg respectively) and the highest content of P was found in maize residual stalk (0.84 g/kg). Residual straw nutritive values of six kinds of crops were evaluated by intake rate of dry matter, the order from high to low was proso millet(52.22%)>maize(48.07%)>sorghum (44.86%)>foxtail millet(41.28%)>wheat(30.91%)>oat(29.41%).
