近年来,在陕西关中一些地方,秋收后多将玉米秸秆沿铁路、公路、渠岸两侧靠树木堆放,有的集中于地头。入冬后,玉米秸秆被焚烧的现象随处可见。据估计,每年大约有几十万亩的玉米秸秆被烧掉。这不仅白白浪费掉资源,破坏路旁树木,污染环境,且有引起火灾的危险。应予坚决制止。秸秆是生物能源,它可用作饲料、肥料、燃料、沼气原料及制作食用菌的原料。把玉米秆作成堆肥后,含有机物约10%左右,氮3.5%左右,还有磷和钾。如果秸秆还田,可增加土壤中的有机质,具有明显的增
In recent years, some places in Guanzhong of Shaanxi Province have put corn stalks along the railways, highways and canals along the banks of the riverbanks after the autumn harvest, and some have concentrated on the ground. After winter, corn stalks are burned everywhere phenomenon. It is estimated that about a few hundred thousand mu of corn stalks are burned each year. This not only wasted resources, destroyed roadside trees, polluted the environment, and caused the danger of fire. Should be resolutely stopped. Straw is a bioenergy source that can be used as feedstock, fertilizer, fuel, biogas feedstock, and edible fungi. Composting corn stalks, containing about 10% of organic matter, about 3.5% of nitrogen, as well as phosphorus and potassium. If straw return to the soil, can increase the organic matter, with a significant increase
