Ophiopogon japonlcus ophiopogon japonlcus plants. Alias: Maimen Dong, step grass. With Ziyin Sheng Jin, lungs and cough, pure heart Chufan function. Indications of fever, injury, hot dry cough, tuberculosis hemoptysis embolism. Mainly produced in Zhejiang, Sichuan, Guangxi and other provinces (districts). [Growth habit] Ophiopogon hi warm and moist environment. Loose, fertile, well-drained sandy loam is preferred for soil. Pre-growth needs to be properly shaded, if the direct light, the leaves yellow, growth and development affected. Ability to withstand 0 °C low temperature, moisture, fertilizer. [Propagation method] Breeding by branch. 1. Land selection and site preparation: Choose convenient drainage and irrigation, sandy loam with loose and fertile soil. After multiple plowshares, apply 2000-3000 kg of farmyard fertilizer per acre, pick up the grain from the manure, and spread it to a width of 1 to 1.2 meters and a height of about 20 centimeters. . 2. Dividing in multiple plants: Before and after Ching Ming, excavate the old plants, remove the roots, fibrous roots, and old rhizomes. Divide the tufted plants into individual plants and cut 1/3 of the length of the leaves. The seedlings were immersed in clean water for 10-15 minutes, and then planted at a spacing of 16 cm x 26 cm. Four to six plants per hole were planted, and the depth was about 3 cm. After planting, the root water was poured. ã€Field Management】 1. Cultivated weeding and intercropping: The early growth of Ophiopogon grows slowly, and weeds grow easily. Weeding should be done. Ophiopogon in the early period needs shading to avoid light, and beans and vegetable crops can be appropriately used between rows. 2. Topdressing: Spring and autumn are a large number of tillers and root enlargement stages of Ophiopogon japonicus. Potassium and potassium fertilizers should be re-applied, and nitrogen fertilizer should be used. 25 kg of calcium phosphate per mu, 1,500 kg of human waste, and 100 kg of cake fertilizer should be applied. In addition, pay attention to irrigation during the dry season to keep the soil moist. ã€Pest Control】 Black spot damages the leaves and brown spots develop. Diseased leaves were cut at the time of onset, and 1:1:100 Bordeaux fluid or 65% Zeoxin 400 times spray was used for prevention and treatment. The nematode nematodes caused the root tips of Ophiopogon to have knob-like protrusions and poor growth. Control methods: rotation with rice; water dripping with tea bran. During root formation, soil moisture is too high and prone to bad potato disease. Control methods: Overturn winter soil before planting; select well-drained sandy loam; pay attention to drainage during root formation. [collection and processing] Ophiopogon japonicus root medicine. After 2 to 3 years of planting, they are harvested from April to May. Dig up the Ophiopogon japonicus, shake off the earth, take off the roots of the sun, soften the sun, and then rub it again and again, until it has been dried and dried, it can be used medicinally. Medicinal herbs, such as Ophiopogon japonicus Olea liviopespicat and broadleaf Ophiopogon japonicus topeplatyphyllawangettang, are also used. The former is mainly produced in Sichuan, Jiangsu, and Anhui provinces, and the latter is mainly produced in Guangxi.
