本文研究了水稻、小麦、玉米、油菜和棉花5种农作物收获后,在田间对稻秸和麦秸采用机械收集打捆,对玉米秸、油菜秸和棉花秸采用人工捡拾打捆,并将这5种秸秆捆储存在遮雨通风的自然环境中,同时跟踪测试秸秆燃料性能基本参数——含水率、热值、温度和体积密度的变化规律。结果表明:在四川省2009年至2011年的正常年份下,小麦、玉米、油菜和棉花这4种秸秆捆在遮雨通风的自然环境中均可安全储存并作燃料,唯有水稻秸秆捆储存期间发生霉变,不适合作燃料。
After harvesting five kinds of crops including rice, wheat, corn, rapeseed and cotton, the rice straw and wheat straw were mechanically collected and bundled in the field. The corn stalks, rape straw and cotton stalks were manually picked and bundled, Straw bales stored in the sheltered natural environment, while tracking the basic parameters of straw fuel testing - moisture content, calorific value, temperature and bulk density changes. The results showed that in the normal years from 2009 to 2011 in Sichuan Province, the four straw bales of wheat, corn, rape and cotton could be safely stored and used as fuel in the sheltered and ventilated natural environment, and only the storage of rice straw bales During mildew, not suitable for fuel.
