(b) Planting methods
1. Seed propagation Seeds of Anemarrhenae are gradually matured before and after the great heat. After harvesting, threshing to net impurities, stored in ventilated and dry place. Seed propagation can be sowed in spring and autumn. Spring sowing in April; Autumn sowing in October-November. In the entire well, open a 2 cm deep ditch at a 30-35 cm pitch. Spread the seeds evenly into the ditch, cover the soil, rub it flat, slightly suppress it, and water it. Keep the ground moist and emerge in about 20 days. About 1-1.5 kg of seed per acre is required. Autumn sowing has a high germination rate and is neat and tidy.
2. Roots propagation Spring planting after thawing, before germination, autumn planting after the stems and leaves withered yellow. In the whole cockroach, the spacing is 30-35 centimeters, the spacing is 15-20 centimeters, and the depth is 7 centimeters. Cut out the rhizomes of Rhizoma Anemarrhenae to remove residual stems and fibrous roots, and poke the roots of the buds into small pieces of 4-7 cm long. Place a section of each hole with the buds facing up. Cover soil and water. It is also possible to pour a large amount of water before planting, and then do the planting and planting, but do not over-humidify the surface to prevent rot. Need to grow 90 kg per acre.
(C) Field management After sowing, keep the soil moist and emerge about 20 days. When the seedling height is 3-4 cm, the soil is sloppy and the height of the seedling is 7-10 cm. The seedlings are planted at a spacing of 15-20 cm. If the climate is dry during the seedling stage, it should be properly watered. Anemarrhena lucidum cultivated with rhizome ramets grew slowly in the previous year and should be poured with small water. The second year of vigorous growth requires an appropriate increase in the number of watering. In the second year of seedling planting and seed seeding, when the seedling height was 15-20 cm, superphosphate 20 kg plus 10 kg ammonium sulfate was applied per acre. Ditch the lines between the rows and combine the loose soil after the application to embed the fertilizer in the soil. If you do not need to stay in the species, you should cut the calyx in time. High temperature and rainy season should pay attention to exclude water.
(IV) Diseases and Insect Pests A mother-in-law has a strong ability to resist diseases and generally does not need to use pesticides for special prevention and control.
The main insect pests are flaws that harm the seedlings and rhizomes. Control by conventional methods.
(5) Harvesting and Processing
1. Harvested species of Anemarrhena and Anemarrhena lucidum were both plucked in spring and autumn. After thawing in spring, before the germination, the stems and leaves of the ground after the fall yellow to before freezing. The roots of the underground rhizomes were shaved with earthworms. The roots and soils of the stems and leaves were removed as Anemarrhenae. The freshly known Anemarrhena assimilate timely in the spring and autumn seasons has a high dry rate and good quality. Wild Tumenomus is generally suitable for autumn harvest. Because it is not easy to find before sprouting in the spring, the planing of the seeds after germination has a certain influence on the quality of the products. The harvest time of domestic species of Anemarrhenae requires 4-5 years of propagation with seeds and 3-4 years of propagation with roots.
2. Processing Maozhimu (1) Drying method: Place the harvested Anemarrhena asparagus on a sunny open field or a drying platform, beat the piles and beat it once every 7 days, so repeated many times until the sun Dry is Mao Zhimu. Usually takes about 60-70 days. (2) Drying method: The fresh rhizome is placed on a baking oven, turning it while baking, and heating it evenly. When it is half dry, it will be taken out and put on the drying table to dry it, and the humidity will continue to be baked until it reaches eight. When it is dry, dry it again and pick it again. This can be dried after two in and two out. Baking should not be rushed to prevent baking.
The rind's fresh skin is dried and dried. If it is sunny, it usually takes 2-3 days to dry.
