Straw mulching ridge-side (wide) furrow sowing crop cultivation method for dry land

The invention discloses a straw mulching ridge-side (wide) furrow sowing crop cultivation method for dry land, and relates to the field of crop cultivation. The method is characterized by comprising the following steps: (1) land preparation and fertilization: selecting flat plots, and applying base fertilizer in combination with deep ploughing and land preparation before sowing; (2) ridging: carrying out ridging at equal intervals by machinery in a flat field to form ridges and furrows, and arranging the ridges and the furrows in a spaced manner; (3) straw mulching: uniformly mulching ridge surfaces with crushed straw; (4) sowing: performing strip sowing or wide uniform sowing on crops in ridge side furrows, and properly increasing density; and (5) field management: carrying out fertilizerdressing, pest and disease control and returning straw to the field after mulching. The crop straw is used as a raw material to replace mulching films for green mulching according to mulching evaporation inhabitation and rid
