Terraces

The terraced fields are [1] in the hills on the hillside along the contours of the direction of the construction of the strip-like or wave-like section of the field. It is an effective measure to control the soil and water loss of slope farmland, and it is very effective in water storage, soil conservation and grain production. Terraced ventilation and light conditions are better, is conducive to crop growth and nutrient accumulation. According to the slope of different fields and horizontal terraces, slope terraces, double terraces and so on. The width of the terraced fields depends on the size of the ground slope, the thickness of the soil, the way of farming, the number of labor and economic conditions, and the irrigation and drainage system, the unified planning of the road. When cultivating terraces, we should keep the topsoil, and the terraced fields will be cultivated, and the soil fertility will be accelerated and the soil fertility will be improved.
