What are the latest measures for frost protection of wheat in early spring?
Hooeing: When the soil is thawing and releasing moisture, hoeing the surface while it is still frozen can loosen the soil, preserve moisture, raise the temperature, and control weeds, enhancing the wheat seedlings' ability to withstand the cold. Regardless of whether the seedlings are weak, overly vigorous, or strong, hoeing should be done promptly during the green-up stage; for fields with a tendency toward excessive growth, deeper hoeing can be done as appropriate to suppress spring tillering. When hoeing, be careful to hoe shallowly and finely, and push apart clods as you go; if the soil is first pressed before hoeing, the soil will not be hollow, thus achieving the effect of loose on top and firm below, drawing up moisture and preserving it.

Occurrence Characteristics and Remedial Measures of Spring Frost Damage in Wheat
Every year in February and March of spring, cold air frequently breaks out and moves southward in the north, with large temperature drops during the process, and wheat that has jointed too early often suffers freeze damage. At this time, for seedlings growing too vigorously, the method of pressing should be adopted to inhibit growth; for weak seedlings, reasonable topdressing should be applied to promote weak ones into strong ones
