When the soil is dry in the field after wheat wintering, the soil can be drowned at any time. Try to avoid long-term water accumulation in the field after irrigation. When fertilization is required, the fertilizer can be applied when the soil is wet after drowning (the fertilizer cannot be spread when there is water on the wheat leaf). In the wintering period, if the nighttime temperature is too low and there may be severe freezing, it is better to irrigate the water in the morning and ensure that the water is infiltrated or discharged in time. There is no water in the field to avoid causing damage such as “rooting†and “cuttingâ€. This kind of harm is more common in the north and generally does not appear in places like Gaoyou.)
