一、丰富的农业剩余物资源是我省沼气发酵的物质基础我省地处长江、淮河流域,横跨亚热带和暖温带地区,自然条件优越。全省各地太阳的年辐射量为110—130千卡/cm~2,阜阳、砀山、毫县一带可达130千卡/cm_2,沿江一带和山区,大致相等,仅115千卡/cm_2。所以,农业剩余物的资源是很丰富的。根据省统计局和农业厅于1981年公布的十种主要作物的产量,参照有关资料(……)等,确定秸秆重量和作物产量的比例概数,以吨为单位计算农业剩余物资源,列于表1。

First, rich agricultural residue resources is the material basis for biogas fermentation in our province. The province is located in the Yangtze River, Huaihe River, across the subtropical and warm temperate regions, natural conditions are superior. The annual amount of solar radiation in the whole province is 110-130 kcal / cm ~ 2, up to 130 kcal / cm_2 in Fuyang, Dangshan and Muxian areas, and roughly equal to 115 kcal / cm_2 along the Yangtze River. Therefore, the resources of agricultural residues are very rich. According to the output of ten major crops announced by the Provincial Bureau of Statistics and the Ministry of Agriculture in 1981, and referring to the relevant data (......), determine the proportion of the total amount of straw and crop yield, and calculate the amount of agricultural residue in tonnes Table 1.
