本文从两个地区的农田养分投入量和产出量入手,宏观分析了该地区农田养分平衡状况。有机肥与化肥配施,既能增加作物产量,也能培肥地力,是维持农田养分良性循环的良好途径。
This article starts from the input and output of farmland nutrients in the two regions, and analyzes the situation of farmland nutrient balance in this area macroscopically. The combination of organic fertilizer and chemical fertilizer not only increases crop yield but also fertilizes soil fertility, which is a good way to maintain a virtuous circle of nutrient in farmland.
