Scrophulariaceae, alias Yuanshen, black ginseng, Zhejiang Scrophulariaceae. Herbs perennial, with root medicine, there are nourishing yin and reducing fire, Runzao Sheng Jin, swelling and detoxification and other effects. Slightly cold, sweet, bitter, salty. For the treatment of Yin Huo-wang, irritability, hot flashes, night sweats, sore throat, red eyes, lymphatic tuberculosis, swollen sore, Tianjin deficiency constipation embolism. Mainly produced in the Yangtze River basin. Scrophulariaceae has ended its price slump for many years, and the market price has now reached 4-5 yuan per kilogram, making it a popular variety for medicinal plants. Scrophulariaceae has a wide adaptability, prefers warm and humid climate, and has a certain ability to resist cold and drought. The soil is rich in soil, fertile, loose, and well-drained loam. Not suitable for continuous production. Its cultivation techniques are: First, propagation methods can be used for seed propagation, cutting propagation and propagation of seed buds. The production of multi-use buds (root buds) breeding. (1) Seed propagation Mature seeds harvested in the fall are stored in a dry place indoors and sown in the spring of the following year. The southern region can be broadcast in autumn. Wet the soil with water, sow evenly, cover the soil, and then cover with straw to keep moist. After the emergence of pouring water, weeding, weeding Dingmiao. (2) Cuttage propagation In July, Scrophulariaceae twigs were used for cuttings. The saplings of the saplings are cut into short sections of about 15 cm and inserted into the seedbeds to enhance water and fertilizer management. After survival, they were transplanted in the spring of the following year. (3) Breeding buds of buds are propagated with rhizomes with buds. In the north, the breeding materials selected during the autumn harvest are stored in the pit. The pit is 1 square meter square and is about 1 meter deep. The seed buds are placed in the cellar and are about 30 cm thick. The top layer covers one layer of sand and sand. As the temperature decreases, sand and sand are gradually added. Finally, the thickness of the sand reaches about 30 cm. As temperatures rise in the spring, sand is gradually removed and transplants are taken out in early April. In the southern region, planting takes place in the fall. When planting, the rhizomes were diced into several pieces, leaving 2 to 3 buds per piece, 1 rhizomes per hole and buds pointing upwards. In addition, some also use ramets to reproduce. Second, the selection of plants and soil preparation of deep-rooted plants, should choose to sunny deep light loam or loam soil cultivation. Avoid continuous works. Formerly made of leguminous or gramineous crops as well. After the previous harvest, 1,000 kg of cooked manure was applied per 667 square meters, and the whole plant was deep-rolled and flattened. Thirdly, planting pods with a spacing of 40 centimeters and a 30-centimeter hole dig a hole with a depth of 10 centimeters. The stalk buds were planted in the hole, one for each hole, and the buds were facing upwards. Each hole covers 1 grass and wood ash mixed with human and animal waste water, covering the soil to the hole level. Seedlings were transplanted and transplanted with cuttings, and the density was the same as that of seedlings. Fourth, field management (1) cultivating and weeding Scrophularia in the growing period of general tillage weeding 3 times. At the end of March and early April, when the seedlings grow to about 5 cm, weeding and weeding will be promoted in time to promote the growth of seedlings. In the middle of May, proper weeding will be needed for weeding; in June and July, the seedlings will need to be cultivated and cultivated again before the closure of the seedlings. Promote root growth and prevent lodging. (2) Top dressing after top tillage. After the first cultivator, about 1,500 kilograms of manure wastewater per 667 square meters, a small amount of nitrogen fertilizer can be added, 10 kg of urea per 667 square meters; after the second cultivator, the highest concentrations of human and animal manure water are followed. 2000 kg per 667 square meters, plus 30 kg of superphosphate, 15 kg of potassium sulfate; during the third cultivator, top-dressing compost of phosphorus and potash, 1500 kg of compost per 667 square meters, 50 kg of superphosphate 25 kg of potassium sulfate. After topdressing earth. (3) When the flowering part of the flowering part of the local flowering part blooms, cut the calyx timely and avoid competing for nutrients to promote the swelling of the roots. (4) Moisture management The gutter drains often during the rainy season. In addition to severe drought, watering is generally not required. Even if it is watered, it cannot be poured too much. V. Harvest processing 1. Harvest Scrophulariaceae planting the same year, 10-10 months when the local part of withered when digging. The stems are cut off first, then the underground part is planed and the rhizomes with the buds are selected. 2. The roots that will be used for medicinal purposes will be dried during the day and accumulated at night. Repeatedly stacking and drying to semi-dry, accumulation of 2 to 3 days, "sweat", so that the roots of the root black, and then drying during the day, night accumulation, until fully dry. When it rains, it can be baked, temperature is about 60°C, and it is turned when necessary. When it is dry, it will be “sweat†and then dried.
