Shoot dry, alias fan grass, thin mountain fan, flat bamboo and so on. More were born in the hilly wilderness of hilly terrain. It is distributed throughout the country. The underground rhizomes are used for medicine, which has the effects of lowering the fire, detoxifying the lungs, removing the pus, reducing swelling, dissolving blood, and eliminating convulsions. Indications: tonsillitis, sore throat, hyperactivity of lung phlegm, cough, anti-asthma, arthritis, toothache embolism, sore throat, coughing, upper gas, sputum, sputum tuberculosis, malaria mother, women Closed, swollen sore.
The morphological characteristics are perennial herbs of the iris family. The rhizomes are nodular and go horizontally. The skin is bright yellow and surrounded by multiple fibrous roots. Stems erect, 40-150 cm tall; leaves alternate, often gathered in the stem base, nesting each other and holding the stem, arranged in two rows, up to 4 cm wide, apex acuminate, with multiple parallel veins. Inflorescences terminal, forklike, flowers orange-yellow, bracts membranous, ovoid, tepals 6, two rounds, bases connate into short tube, outer ones long obovate, spreading, scattered with dark red spots, inner wheel with The shape of the outer wheel shrank. Stamens 3, filaments red, lower pistil ovary, 3-loculed, with 3 longitudinal grooves, style, stigma inflated, 3-lobed. Capsule triangular-obovate, 3-loculed, with 3-8 seeds per chamber. Seeds round, black, shiny.
First, growth habits: shoot dry and hi sunny, warm and dry climate. Drought-resistant, cold and afraid of water. The requirement for soil is not strict. It is better to use deep, loose, fertile organic-rich loam. Low-landing should not be title="planting, planting technology" planting.
Second, the preparation and fertilization: Select high-lying, well-drained fields intensive cultivation. Combined with soil preparation, sufficient basal fertilizer was applied; 3000 kg of landfilled fertilizer per mu, 20 kg of urea, and 50 kg of phosphorus and potassium fertilizer. Then do the trick, level the surface and wait for the sowing.
Third, sowing: shoot dry seed propagation. Two-step nursery and transplanting. Rhizome breeding can also be used. Sowing period before and after the Ching Ming Festival. Seed nursery. Before the seeding, the seedlings were sprayed on the seeded shoots, and the collected shoots were uniformly mixed with 5 times of moist sand to be stored indoors and sown when the seed was spit white. Sowing first into a shallow ditch on the entire surface of the sorghum, and then sprinkle the seeds of the germinating stalks evenly into the ditch, watering it to protect the seedlings. And strengthen field management, transplanting after one year of growth. 10 kg per acre sowing rate. One mu of nursery can be used to plant 10 mu of Daejeon. Transplanting. One year of shoot dry seedlings, in the fall of the year or the second year of the Spring Festival will be planted on the entire surface of a good lotus seedling, watering and protecting it to facilitate survival. Row spacing 3020 cm. Rootstock breeding. Before and after Ching Ming, we selected strong shoots with no disease and insect pests and cut them into small sections. Each section had 1-2 buds as a seed plant and were planted on the whole plant surface. Watering to protect your life. Line spacing 25 20 cm.
Fourth, field management: After the injection of dry seedlings, we should pay attention to cultivator weeding, if the size of title = "planting, planting technology," planting should be used before the seedlings using herbicide herbicide for soil treatment, can effectively control all kinds of weeds. Dry water in time in dry weather, pay attention to drainage in rainy weather. The second year of the spring fertilizer: topdressing 10 kg of urea per mu and 10 kg of potassium dihydrogen phosphate. Shooting generally begins in 2 years when the bolting flowering occurs. If no seeding is required, the flowering branch can be cut to reduce nutrient consumption.
V. Prevention and control of diseases and insect pests: Diseases caused by radiating shoots mainly include rust damage to the leaves, and brown rust spots appear. In the early stage of disease, it can be sprayed with 50% dichlorphyrin 400 times spray. once a week. Spray three times. Triadimefon can also be used for prevention and treatment. Underground pests can be controlled with phoxim.
6. Harvesting and Processing: Shooting is generally harvested after the stems and leaves of the ground have fallen for 2 to 3 years. When harvesting, first cut the stems and leaves on the ground, then plan the underground rhizomes, and then go to the net soil and dry them to be used for medicine. 200 kg of dry produce per mu.
VII. Operation of the market conditions: 7.7-7 yuan in 2000; 7 yuan in 2001; 7-11 yuan in 2002; 11-16 yuan in 2003; 16--14 yuan in 2004; 10-19 yuan in 2005 2006-24-22 yuan; 2007 22 yuan. 20-$30 in 2008-2009
