Leek yellow is planted by soil cultivation, shading and other measures to soften the roots of normal leeks in dark environment. The root of leek is special, it has no main root and lateral root, and there is less root hair, only a relatively fat string fibrous root, which is planted at the base of the stem disc of the rhizome in the same year of sowing.
Farmers spend more time planting leeks than leeks because they want to provide a relatively suitable growth environment for leeks. Dry leeks in the shade, and when they are cut, they will absorb sunlight and carry out photosynthesis to protect leeks.
Introduction of leek
Leek yellow is formed by the growth of leek roots in the dark environment. Because there is no sunshine supply, leeks can't produce photosynthetic chlorophyll, so the grown leeks turn yellow, which is called "leek yellow". Leek yellow is a kind of yellow leek which is softened and cultivated in the dark by measures such as soil cultivation, shading and covering.
The root of leek is special, with no main root and lateral root, less root hair and only string-shaped fat fibrous roots, which are planted at the base of rhizome stem plate in the same year of sowing; In the second year, plant around the rhizome and its side. The length of fibrous roots is 30 cm.
