Astragalus planting technology

First, an overview of the yellow wolfberry, alias bar, gold tea. English name: RADIXSCUTELLARIAE, for the labiatae plant, its root for medicinal purposes. Ingredients, including astragalus, astragaloside, wogonin and astragaloside, have heat, purging, detoxification, tocolysis and other effects. Indications fever, pneumonia, hemoptysis, jaundice, hepatitis, dysentery, red eyes, fetal movements, restlessness, etc. Second, plant morphology Astragalus is a perennial herb, plant height 20-50cm, the main root was conical, about 10-30cm long, about 1-2cm in diameter, the skin was yellow brown, internal yellow. Stem growing, base undulate, slightly ascending or erect, branches numerous and fine, plant square, green or purple green. Leaves opposite; leaf blade lanceolate, apex acuminate or cuspidate, base rounded, entire. Inflorescences terminal, flowers densely arranged on one side; calyx tube-shaped outside densely villous; corolla purple, 2-lipped; stamens 4, 2; pistil 1, ovary 4 deep, ovary Orange fleshy flower disk. 4 small nuts, ovate, black, tumorous on the surface, diameter of about 1mm, surrounded by the inside of the deposit. Flowering from June to September, fruiting period from July to October. Third, the biological characteristics Huang Xi warm and climate, resistant to cold, engage in drought. The original wild on the slopes, mantle, forest edge dry sunny place. The soil requirements are not strict, well-drained, fertile sandy loam fine, can be planted in thin hills. Low-lying land should not be planted. Fourth, cultivation techniques 1, site preparation fertilization: choose loose, fertilizer, irrigation conditions, deep sandy soil land. The soil-fertilizer 2000-2500kg per mu will be scattered in the ground. Deep plowing 20-24cm, fine leveling, 90cm wide flat, open drainage ditch. When the ground is dry, water is poured into the pot first, and after the water is infiltrated, the topsoil will be dried when it is slightly dry. 2, breeding methods (1) breeding with seeds. Spring sowing between the "spring equinox" to "clear and bright", the summer sowing in the "summer solstice" to "start autumn" between. Live broadcast. On the entire surface of the plant, 24 cm spacing and 1 cm deep ditch were used to block the seeds and evenly spread them into the ditch. The soil was covered with 0.5 cm, and the soil level was slightly suppressed, so that the seed was closely integrated with the soil. Keeping the surface moist, about 10 days after sowing. Use 1.5-2kg per acre. (2) Transplanting mus. Before and after the “Qingming”, on the whole surface of the sorghum, press the row spacing 12cm, open the 0.5cm deep ditch, put the seeds in the fine sand and put it in the ditch, cover the soil and lay flat, slightly suppress it, cover with a layer of grass or wheat straw, Keep surface soil moist. About 2-3kg per acre seed. Transplanting: Spring sowing was transplanted before and after "Early Autumn", and transplanted after germination in the second year of summer sowing. In the whole field, press the row spacing 24cm, open 12-15cm depth ditch, plant the seedlings 12cm away from the plant, the buds head up, about 15cm below the ground, so that the roots upright, covering the soil, compaction, so that the root and soil in close contact . Water after planting to ensure survival. 3, field management (1) seedling period management. After sowing, keep the ground moist and help the seedlings unearth. After the seedlings are unearthed, the covered weeds are removed, and the topsoil is gently moved to keep the ground loose. The bottom is moist and conducive to root elongation. When the seedlings grow to 4 cm in height, they are smashed once and the weak seedlings are too dense. Nursery seedlings are planted at a distance of 6 cm from the nursery, and seedlings are planted only at a spacing of 12 cm. After the seedlings are established, there will be grass and grasshoppers, watering in the dry season, flood prevention in the rainy season, and no accumulation of water in the ground. (2) Management after transplanting. After being alive, pay attention to the soil and keep the ground clean. Huang Hao has stronger drought resistance. In case of severe drought or fertilizer, it can be properly watered, and it is generally not necessary to water. After the “summer season”, 1000 kg of soil and 150 kg of wood ash were planted per acre, and after mixing, a shallow ditch was applied between the rows. After the cover soil was leveled, weeding was often performed to keep the grass free of weeds. It usually blooms in June, but it can be opened until September. The maturity of seeds is inconsistent and falls with maturity. If the seeds are harvested, they should be harvested in time and stored for future use. If you do not need to collect seeds, you can remove buds to grow roots. V. Prevention and Control of Diseases and Insect Pests According to our district's production practices and observations over the years. At present, the occurrence of pests and diseases in Astragalus is small, and generally no special control is required. Only a few plots are found to have the occurrence of leaf blight. Leaf blight: The source of the disease is a fungus in the fungus. The main damage leaves. Symptoms extend inward from the tip of the leaf or the rim. The irregular black-spotted lesions spread quickly from top to bottom, causing the leaves to die and prone to onset in high temperatures and rainy seasons. Control methods: In winter, the diseased plants will be treated, and the infected strains will be set aside and burned to remove the pathogenic bacteria. In the early stage of disease, 50% carbendazim WP is used 1000 times 1:1:120 Bordeaux spray, spray once every 7-10 days, and it can be cured 2-3 times. Six, harvesting and processing sowing and general two-year harvest, can also be harvested that year. Before and after the frost fall, select the sunny days to plan, cut off the stems and leaves and the soil, dry or dry. During the drying process, prevent the water from getting wet and rain, so as not to see the water turn green, and the final deterioration will be black and affect the quality. To remove the root, you can use it for medicinal purposes.For every 3-4kg of fresh root, 1kg of dry goods can be processed, and generally 200-300kg of dried goods can be harvested per acre.The dry goods should be rough, solid, and yellow.

The pharmaceutical industry is divided into three categories: natural extraction, biosynthesis and chemical synthesis. Pharmaceutical Intermediate is a fine chemical product in the production process from pharmaceutical chemical raw materials to raw materials or drugs. The synthesis of chemical drugs depends on high quality Pharmaceutical Intermediates. In short, pharmaceutical intermediates refer to semi-finished products or important raw materials for the production of drugs. Pharmaceutical intermediates are also an indispensable part of supporting the pharmaceutical industry. At present, there are about hundreds of pharmaceutical intermediates products, and they are constantly evolving from the old to the new, forming a large number of sub-molecular industries in the pharmaceutical intermediates industry, mainly including: cephalosporin intermediates, amino acid protectants, vitamin intermediates, quinolones intermediates, and other types of intermediates, such as medical disinfectant intermediates Antiepileptic drugs intermediates, fluorine-containing pyridine intermediates, steroid medicine intermediates and so on. The production of synthetic drugs and the research and development of new varieties are inseparable from the production and development of pharmaceutical intermediates. At present, the main pharmaceutical intermediates used in the production of drugs by chemical synthesis methods are vermicular and its derivatives, morphine and its derivatives, street and mushroom compounds, and used in the production of lactamides and cephalosporins antibiotics.
