Achyranthes bidentata is the dry root of the Cyathula officinalis Kuan (Cyathula officinalis Kuan), alias Niu Xi. With blood stasis, Tom Lee joints and other effects for the treatment of amenorrhea. Hematuria, joint pain, traumatic injury embolism. Leshan, Ya'an, Liangshan, and other cities in Sichuan Province are all distributed. The cultivation history of Tianquan and Jingjing counties is longer, and the output is large and the quality is good. (-) Morphological perennial herb, 50-100 cm tall. The main root is long cylindrical, brown soil, slightly sweet taste, stem erect, nearly cylindrical stem below, near the middle of the four-sided or nearly square, with rough hair, slightly enlarged. Leaves opposite, petiole densely shaggy, leaves elliptic, apex acuminate, base cuneate, entire, surface dark green. The green or white flower of the item or axillary is born, and the flower head is integrated into the round head. Umbilica oblong oval, dark gray. The base is slightly pubescent, seeds ovate, auburn. Flowering from June to July, fruiting from August to September. (b) Growth habits Achyranthes kawaguchi enjoys a cold and humid natural environment. Sichuan is mostly cultivated in alpine mountainous areas with an altitude of 1200-2 000 meters. The annual rainfall is generally more than 1500 mm, and there are 3-4 months of snow in winter. At about 1,500 meters above sea level, mature seeds growing for 3-4 years can be emerged 10-15 days after sowing, and the germination rate is high, the seed life is 1 year, the first year after sowing is vegetative growth, the second year is Reproductive growth. Summer is a vigorous growth period, and at the same time, it grows in roots, and it enters the winter dormancy period in late autumn and early winter. (III) Cultivation Techniques 1. Loosening and fertile loam soils are preferred for land selection and soil preparation, and slopes are generally preferred for sunny slopes. Before September-October, when the land is deep-swept, the best depth is 30 cm or more. After the Qingming, the next year, it will be turned again and again, and the height will be about 1.3 meters. 2. Breeding methods reproduce with seeds. The seed used in the cultivation is essentially a meridian, and the seed germination power varies with the growth period. The seeds of the three to four-year-old seedlings are the best, and the seeds that were cultivated in the same year often cannot germinate, and the seeds are not used for breeding every other year. Planting spring and autumn sowing in spring and spring sowing in April, due to different altitudes, sowing time is different, the lower elevation can be earlier, in early broadcast after the snow is appropriate, autumn broadcast before and after August. The main producing areas generally adopt the methods of spring sowing in high mountains and autumn sowing in low mountains. The rate of emergence is high and there are fewer nests. 3. Field management (l) cultivating weeds and seedlings Weeding and weeding 3-4 times a year. For the first time in the year of sowing, in the middle or late May, it is appropriate to scoop or pull by hand, and combine the seedlings and make up the seedlings. Each plant has 4-6 seedlings. This time weeding is very important, as soon as possible; In the middle and late June, before the cultivator, the seedlings were reground once, and 2-3 strains of seedlings were planted in each litter, and they were each performed again in July-August. Weeding and weeding 2-3 times in the second year. For the third year to be harvested, only l-2 times are performed. (2) Fertilizing soil combines cultivator and top dressing three times each year. After the middle tillage, the first and second applications of human and animal waste water and grass ash, and soil freezing. The thickness of the soil should be set so that the root shoots are buried in the soil about 7 cm. If you do not earth, the root is easily frozen, resulting in lack of nest production. 4. Pest control (1) Blackhead disease occurs mostly in spring and summer, mainly due to the fact that the head of the reed is too thin, and in the winter, it is frost-destroying and causes black moldy and rotten. Control methods: pay attention to flood control, winter soil. (2) Nematode diseases occur at low altitudes and form rugged sarcomas on the roots. Control methods: Pay attention to soil selection; treat 35-45 kg of soil with each drop of 35-45 grams per mu. (3) Occurrence of the leafhoppers from May to June occurs when the leaves bite into small holes. Control methods: Use imidosulfan 800 times or trichlorfon 1000 times spray. (4) Caterpillars and spider mites attack leaves from May to June. Control methods: Use 40% Dimethoate EC 800-1500 times liquid spray. (D) harvest and processing of Sichuan Achyranthes 3-4 years after sowing in October-November harvest. Require deep digging to reduce rooting. After the excavation, go to the dirt, cut the head of the reed, cut the fibrous roots, cut off the roots, and make the main root. Side reports are all single. Then, according to the size of the root bar, straighten out the small ones, stand upright and use an anthracite fire to dry or put it on the sun. After half-drying, stack it for several days, return it, then dry it or dry it until it's dry. Usually three-year-old dry produce 150-200 kg per mu, 200-250 kg in four years.
