Should wheat be watered after it is full?

Wheat needs watering after it is full.

Cause analysis:

Every year around May 2 1 of the Gregorian calendar, when the sun reaches 60 degrees of the yellow meridian, it is called Xiaoman, which is the eighth solar term in the twenty-four solar terms of the lunar calendar. At this time, it is the "filling" period of wheat. Wheat looks full, but in fact it is only "half full" and not mature, so it is called Xiaoman. At this time, special attention should be paid to field management and watering to ensure the growth of wheat.
