The three methods commonly used for top dressing of corn include deep furrow chase, ridge cover plow cover, and planer pit dressing. The roots of the plants have been initially developed and formed when topdressing. If machinery is used, rooting should be minimized. The depth of fertilization should not be too great, and the horizontal distance (sideways) from the plants should also be appropriate. Under normal circumstances, the depth of corn dressing is preferably 10-15 cm, and the lateral distance is 10-12 cm.
Ditch deep chase. When the corn has 7-8 leaves, it is about 40 cm high. The fertilizer is used to dig the ditch with a fertiliser. The fertilizing spade applies the chemical fertilizer directly to the depth of the ditch. This method breaks down the phenomenon of less fertilizer, less soil, heavy roots, and low fertilizer utilization rate. Fertilizer is not easy to evaporate. Early recovery and deep fertilizer are adopted at the seedling stage to increase fertilizer utilization.
The sloping plough covers the ridge. In combination with the third cultivator, the fertilizer was applied directly to the ridges, and the fertilizer was then covered with a large plough. The disadvantage is that the fertilizer is applied to the top of the root. After fertilization, there must be sufficient water to exert the fertilizer effect.
Planting pit top dressing. This method can be top-fertilized according to the required depth of fertilization, and the roots of the crop are deeply rooted to enhance the plant's ability to absorb fertilizer, absorb water, resist drought, and lodging. The need for man-made fertilizer for planing pits between plants is large, and it is not easy to use large-scale topdressing, but it is suitable for vegetables and cash crops.
