A good quality of land preparation and quality requirements are: deep plow, even grazing, rake, flat rake, to achieve the virtual reality, moisture preservation is good, tillage in time. The use of large, medium or small tractors supporting the plowshare, rakes, presses, rotary tiller, basically meet the requirements of corn preparation. Land preparation operations as far as possible before harvest in the autumn after the harvest, to avoid spring earth. Not only the spring soil maturation time is short, and the spring temperature rise faster, wind and windy fur run moisture seriously affect the sowing seedlings. If the rain before sowing, but also shallow tillage and timely rake 耢 soil moisture, sowing while soil moisture.
