How to harvest lotus root properly? Master the correct harvesting method
How is lotus root best harvested? Please give guidance. Harvesting lotus root too early affects yield, while harvesting too late lowers quality. Therefore, the harvest time should be determined according to how early or late the plants develop and the intended use. ① Huaxiang lotus root. The newly formed lotus root is called huaxiang lotus root, also known as tender lotus root. This kind of lotus root has a very low starch content and features a fresh, tender, sweet and crisp flavor. When the lower-layer leaves of huaxiang lotus root are yellow-green, the middle-layer leaves are dark green, the upper leaves have all taken shape, and no new leaves appear in the whole plant, it can be harvested. Early September is the best time, but harvesting at this time affects yield, so only a small amount should be harvested. ② Mid-Autumn lotus root. Mid-Autumn lotus root can be harvested around the Mid-Autumn Festival, when the lower-layer leaves in the whole field have withered, the middle-layer leaves are yellow, and the upper-layer leaves are yellow-green. Harvesting Mid-Autumn lotus root is mainly to meet people's needs for the Mid-Autumn Festival and National Day. ③ Red-rust lotus root and white-rust lotus root. Red-rust lotus root is generally harvested in mid-October, named because the surface of the lotus root has a rust color at this time. At this stage the lotus root contains more starch and can be used for cooked food or processed into lotus root powder. By the end of October, the redness of the lotus root fades and turns white, and it is called white-rust lotus root.
