Bald wheat refers to wheat with insufficient seeds. This kind of wheat will lose water after drying in the sun, which will make it drier. When put into water, it will float to the surface. Floating wheat is called floating wheat because when withered wheat is put into water, it will float on the water.

Some places may also be called green wheat seedlings, which usually refers to wheat that is affected by adverse environment during its growth, resulting in insufficient development of wheat grains.
