The harvesting and processing of roots were harvested before the equinox to the frost fall (from late September to late October) and when the aboveground stems and leaves withered. First dig a trench of 60cm deep on one side of the trench, and then dig it in order to avoid damaging the root. After the excavation, remove the dirt and debris, wash it, dry it until it becomes dry, and tie it into small bundles, and then dry it until it is completely dry. The coarse and even roots, the long and neat rows, and the powdery feet are the best products. Leaf harvesting and processing can be harvested 2 or 3 times a year for spring sowing. The quality of the first harvest is the best. The first harvest was carried out during the period between Mang and the Great Heat (June-July), the second time between the beginning of autumn and the summer heat (August), and the third time during the cold-frost period (October). It is not appropriate to harvest when the weather is hot and rainy, so as to avoid causing a large number of plant deaths. After drying, it should be bundled into small pieces when it is dry to 78% dry, and continue to dry until dry. It is better to have no impurities, complete and dark green, and it is not suitable for exposure. China Agricultural Network Editor
