Artificial cultivation technique of earth fritillaria
In recent years, after the anti-cancer efficacy of earthworm was discovered, the drug companies absorbed a large amount from 1997 to 1999, but due to insufficient production, the selling price skyrocketed to 120 yuan/kg, and the country’s major pharmaceutical companies had no goods at all. Fritillaria has a short production cycle (when it was harvested in the same year of the year) and has a high yield, adapts to a wide area, and requires strict management during the production period. Therefore, the enthusiasm of drug farmers has soared in many parts of the country, which has led to a rise in the price of seed stalks and a rise in prices. The price of stems is as high as RMB 60/kg. Finished product prices are expected to rise again due to supply shortages. Wild resources are increasingly depleted and family production is imperative. First, growth habits: Tubulis prefers a warm and humid climate, resistant to cold, drought resistance, strict requirements on the soil, barren hills within 1500 meters, wasteland, rivers and streams (not suitable for planting), plains can be planted . Second, the cultivation techniques: planting sub-autumn and spring sowing, autumn species before soil freezing (before and after frost) under the species, spring soil thawing (before the Qingming) immediately under the species. Selection of land, site preparation, Mushi farmyard fertilizer (basic fertilizer) 400-500 kilograms, superphosphate 50 kilograms, ammonium nitrate 15 kilograms or urea 10 kilograms. Spread deep plowing land more than 25 centimeters, pondering fine, dry land should be watered, water species in due course. Third, propagation methods: reproduction of fresh phosphorus stems, seeds can also be used for breeding, seed reproduction two years of harvest, fresh stems were harvested in late autumn. About 20 kilograms of fresh phosphorus stalks are used for planting. One seed per hole. Ditch depth 13 cm, spacing 25 cm, spacing 15 cm. To be consistent with the requirements of cultivating weeds, fertilizing, and row spacing. Fourth, the production period management: 1, pest control: in June when the seedling height to 20 cm long, should be sprayed insecticide, killing, fungicide pesticides, should prevent a variety of pests and diseases. The main pests are: aphids, red spiders, and various underground pests. The sprayed pesticides were omethoate, isocarbophos or zincphosphorus, and trichlorfon. The disease has a root rot, leaf blight, can be sprayed fungicides and other fungicides. Spray once a month, so that there is a pest to prevent, have to remove the grass. 2, outside the top dressing, in each spray can add potassium dihydrogen phosphate, leaf treasure, urea, rhizome swelling agent and pesticide mixed spray. The application concentration is the same as that of other crop pests and diseases. 3. Fertilization: In June, the 20-kg P and K fertilizers were applied in the row spacing. Phosphorus and Potassium fertilizers are the main growth methods. In combination with barnyardgrass, 150 kg of plant ash can also be applied per acre. It is also possible to apply 50 kg of CPK fertilizer on rainy days. 5. Mu benefit: 400-600/kg per mu, 1 kg per 4 kg of processed product, and the market reference price is 80-120 yuan per kg. 6. Harvesting and processing: When the leaves and stems are yellow in the late autumn, harvest the stems, dig the stems, wash the soil with the clear water after the tubers are scooped, and then put them in the boiling water and cook them until they are out of the white heart. Dry them or dry them. Can be sold for finished medicines. China Agricultural Network Editor
