摘要
沼气是近年来在农村受到普遍欢迎的清洁能源,其剩余物沼肥是一种优质有机肥料,其养分除含有作物所需的N,P,K元素外,还含有各类氨基酸、腐殖酸、蛋白质、植物生长激素等,为进一步探索沼肥对小麦、油菜生产和土壤改良的效应及影响,笔者在大田生产中进行了试验研究。试验表明,施用沼肥比施用化肥,每公顷可节本增效2000元以上,且产量相当,从而为大面积推广应用沼肥提供理论依据。
To further explore the effect the biogas fertilizer on wheat,rapeseed production and soil improvement,a field experiment were carried out,so as to provide basis for the large area popularization of biogas fertilizer。The result showed that the application of biogas fertilizer could save the cost more than 2000 Yuan per hectare with almost the same production comparing with the application of chemical fertilizer.
