The herbaceous earthflies are used as underground tubers. Generally about 500 kilograms of fresh produce can be produced per mu. Every 4 to 5 kg of fresh product can process 1 kg of dried product. Its cultivation techniques are as follows: First, the election site preparation. Before sowing, choose the soil according to its growth habits, make soil preparation, fertilize (mainly phosphorus and potassium fertilizers), plowing. If the ground is dry, fill it with water and wait until the topsoil is loose. Second, the breeding method. It is mainly used for underground tuber propagation. Each mu of land needs 15 to 20 kg of fresh stems. The spring is planted before and after the Ching Ming period, and there is a fall before the fall. When planting, the spacing is 30 centimeters, the spacing is 15 centimeters, and the depth is 10 centimeters deep. One tuber per hole (two small ones) is placed, and then the soil is covered and slightly suppressed. The temperature of spring sowing is 18 to 20°C. It can emerge in about 15 days, but it does not emerge in the autumn sowing. Third, topdressing water weeding. Autumn Fritillaria doesn't need to be managed in winter. The spring planted earth mother-of-pearl is watered when the weather is dry to promote rooting. During June-August, combined with watering, some phosphorus and potassium fertilizers should be topdressed, and fertilizers can also be applied to the earthworms before raining. Before the stalk is enclosed, pay attention to the loose soil weeding. After the stalk grows, it is removed and the grass is removed. Fourth, pest and disease control. Insects are mainly red spider beetles and aphids, which can be sprayed to kill aphid pesticides. When the soil moisture is high, root rot easily occurs, and thiophanate-methyl or root rot may be sprayed 2 to 3 times. Fifth, special management. Combined with the actual situation during the growth period, foliar fertilizers, rhizome swelling agents, herbicides and paclobutrazol can be used. Six, harvest processing. The Qingming Plant was planted in the late autumn to dig and dig in the late autumn of the next year. Dig out the underground tubers and wash them with clean water, and then put them in boiling water and cook until they have no white heart.
