Harvesting, Processing Methods and Key Technical Points for Dwarf Lilyturf (Ophiopogon japonicus)
Dwarf lilyturf is harvested in the first or second ten days of April of the second or third year after planting. Choose a sunny day, first plow the soil to a depth of 25 cm so that the dwarf lilyturf is turned up, shake off the soil, cut off the tuberous roots and fibrous roots, put them separately into bamboo baskets, and place them in running water, trampling and rubbing them with the feet to wash away the mud and sand.
Spread the washed dwarf lilyturf on a drying mat or in a drying yard to sun-dry; once the water has dried, rub it gently with the hands, then sun-dry again after rubbing, repeating this several times until the fibrous roots are rubbed off, then sun-dry until completely dry, and sieve out impurities to finish. If rainy weather occurs, use a gentle heat of 40-50°C to dry for 15-20 hours, take it out and leave it for a few days, then dry again until completely dry, sieve out impurities, and it is ready as a commercial product.
