Chuanxiong is a traditional Chinese medicine plant commonly used for promoting blood circulation, relieving phlegm and relieving pain. The main producing areas are in Yunnan, Guizhou, Guangxi, Hubei, Jiangxi, Zhejiang, Sichuan and Sichuan. The following is mainly to learn the cultivation techniques of Chuanxiong. 1. Site preparation Cultivate Chuanxiong should choose a soil with a sunny terrain, deep soil layers, good drainage, high fertility, neutral or slightly acidic soil, cold sand and yellow mud, white mud, and wet fields that are not suitable for planting. Remove the weeds before planting, and burn the grass into charcoal to make the fertilizer. According to the topography and drainage conditions, weighed 1.6 to 1.8 meters wide. 2. Planting at the right time In the middle and upper part of August, the planting was carried out in a ditch of 33×20 cm on a well-formed surface, and the ditch was 2 to 3 cm deep. At the same time, a row of scorpions is planted in a row between every 6 to 10 rows to prepare for seedlings. The scorpion must be planted shallowly, placed in the ditch, and the buds are planted into the soil. It is in contact with the soil, and some of the nodes are exposed to the soil surface. 3. Interplanting weeding After planting Chuanxiong, cover the scorpion with sieved compost or soil manure. After planting for about half a month, remove the grass and remove the grass every 20 days. The lack of seedlings combined with cultivating to replenish the seedlings and the last cultivating and weeding, and soil around the rhizome to protect the roots from overwintering. 4. Reasonable topdressing After 2 months of planting, Chuanxiong concentrated the top dressing 3 times, once every 20 days, and the last time required to apply before the frost. The fertilization amount per mu is 1.2 tons of farmyard manure, 30 kilograms of oil cake, 100 kilograms of plant ash, 25 kilograms of ammonium sulfate, 40 kilograms of superphosphate, and 10 kilograms of potassium sulfate. When the spring stems and leaves grow rapidly, the fertilizer is applied once again, and the amount of fertilizer is the same as before. 5. Pest control 5.1 leaf blight It occurs mostly from May to July. When the disease occurs, the leaves produce brown, irregular spots, which then spread to the whole leaves, causing the leaves of the whole plant to die. In the early stage of the disease, spray 65% ​​of sensitized zinc 500 times solution, or 50% of bacteriostatic 1000 times solution, or 1:1:100 Bordeaux mixture. Once every 10 days, 3 to 4 times in a row. 5.2 Powdery mildew From the beginning of June to July, when the temperature is high and high, the incidence is serious. First, the disease occurs from the lower leaves, grayish white powder appears on the leaves and stems, and then gradually spreads upwards. In the later stage, black spots appear in the diseased part, and in severe cases, the stems and leaves turn yellow. Withered. After the harvest, the fields were cleaned and the leaves of the residual plants were burned. In the early stage of the disease, spray with 25% powder rust 1500 times solution or 50% Torrance 1000 times solution, once every 10 days, even spray 2 to 3 times. 5.3 rot disease The root of the diseased root rots into a yellow-brown color, which is water-like, has a special odor, and becomes soft and rot-like. After the growth period, the upper part of the leaves gradually turns yellow and falls off. Immediately after the occurrence, the diseased plants were removed and burned intensively to prevent spread. Pay attention to drainage, especially in the rainy season, too much rain, poor drainage, and serious onset. When receiving and selecting seeds, the sick "sweet" and the rotten "scorpion" are removed. 5.4 stem moth In the nursery stage, the genus Ligusticum chuanenseense was sprayed with 80% dichlorfen 100-150 times aqueous solution, and attention was paid to the prevention and treatment of the first generation second-instar larvae. The plain area used 5:5:100 tobacco stalks and maple yang leaves. Water, a total of 12 days after soaking the scorpion for 12 to 24 hours. 6. Harvest at the right time The second year of planting in the second half of the year is most suitable for mining. Excavation too early, the underground rhizome is not fully mature, and the yield is low. After too late digging, the rhizome is ripe and perishable in the ground. The excavation should be selected on a sunny day, the whole plant should be dug, the soil on the rhizome should be removed, the stems and leaves should be removed, and after roasting with a slight fire, the bamboo cage would be shaken to remove the soil and the fibrous roots. The above is all the points about Sichuan and Sichuan planting. Farmers in need can check out and learn, and hope to help everyone.
