本文通过对发达国家农业生产中出现的化肥施用量相对减少这一趋势的探讨 ,分析了我国农业化肥施用现状 ;并通过对作物秸杆作为燃料获取能量与生产化肥所消耗能量的对比 ,说明从节省能量的角度来看 ,用有机肥部分替代化肥具有一定的合理性 ;指出在我国要实现肥料间的替代 ,首先要解决农村生活燃料的替代问题。
From the discussion the trend of relative decrease of the using chemical fertilizers in developed countries agricultural production, the situation of using chemical fertilizers in China is analyzed. Furthermore, the energy consumption of chemical fertilizer production is compared with energy from the stalks used as fuel. It is explained that organic fertilizer partly substituting for chemical fertilizer is reasonable from aspect of save energy.
