Leek yellow is planted by soil cultivation, shading and other measures to soften the roots of normal leeks in dark environment. The key points of its cultivation are: raising the roots with normal leek roots in the open field, returning them to the roots after repeated frost in the later period, then moving the leek roots into protective facilities such as Leek Valley and Sunshine Bed at a proper time, and finally cultivating fresh leek yellow by using the nutrients stored in the leek roots in weak light.
