Because the planting habits in different regions are different, the row spacing and plant spacing will be different, and the number of trees planted will be different. If it is interplanting ordinary corn, it is necessary to keep the spacing at about 400 meters, and the planting amount of an acre of land will be less.

The seeds of sweet corn, especially super sweet corn, are obviously different from ordinary corn. The surface soil strength of sweet corn seeds is very poor, and the seedlings are thin, so it is difficult to meet the requirements of sowing the whole seedlings at one time, and the seedlings are neat, uniform and Miao Zhuang. The soil quality of the selected plot is suitable for sandy soil or loam, with high fertility, PH value between 6.5 and 7, deep loosening and water retention, and good permeability. Fine soil preparation, so that the sky is solid and the soil is fine.
