Why does the South Wheat District emphasize the quality of the ditch in the wheat field?

Good quality gutters are good for pre-humidification and preservation of seedlings, mid-term scientific management of water to promote fattening by water transfer fertilizer, and late drainage anti-waterlogging. There are deep trenches and deep trenches in the ditch mode, but the basic requirement is that the ditch is deeper than the ditch, and the ditch is deeper than the ditch, and the ditch, waist ditch, gutter and field ditch irrigation ditch are supported by four ditch. Gutters communicate, drainage and patency. It is usually planted in a timely manner after sowing. The width of the cabin is 2.5 to 3.0 meters. The soil to be ditched should be uniformly spread on the surface of the car to ensure that the car is flat. The ditch is required to be straight, flat, deep and narrow (15 to 20 cm deep and 15 to 20 cm wide). The large plots need to be opened (20 to 25 cm deep and 20 to 25 cm wide), and open trenches (depth 25 to 30 cm, width 25 to 30 cm) around the plot.
