Why do corn need to be seedlings?

In the emergence of maize to jointing stage, seedlings can properly control plant growth, promote root growth, enhance root vigor and ability to absorb nutrients and water, inhibit vegetative growth, and promote reproductive growth, generally increasing yield by more than 15% . Corn seedlings are mainly cultivated through deep cultivating and digging, improving soil permeability, eliminating soil compaction, dispersing surface mites, preserving bottom stalks, promoting root stalking, and promoting plant robustness. For corn fields with fertile soil and sufficient water and fertilizer, it is necessary to properly control the watering to prevent the seedlings from growing and not strong; for corn that is sown on wheat ridges, if the soil is dry, it can be properly watered.

Corn seedlings should be "three-three-three": the dampness is not dry, the manure is not thin, the black is not yellow, that is, the soil with good soil moisture, sufficient fertility, and the black-green color of the seedlings should be seedlings. On the contrary, it is not appropriate to carry out seedlings.
