Chuanxiong High-yield Cultivation Techniques

Chuanxiong is an herbaceous plant of the genus Umbelliferae and its tubers are used for medicinal purposes. Can regulate blood circulation, Shun Qi pain, loose rheumatism. As an important traditional Chinese medicine, it is in great demand and is increasing year by year. Chuanxiong has a wide range of adaptability. The climate is mild, humid, sunny, cold-resistant, slightly drought-tolerant, and fear of shading and waterlogging. The soil should be deep in soil, loose and fertile, well drained, rich in organic matter, neutral or slightly acidic, and generally well-grown oil sand or sandy soil. Its high-yielding cultivation techniques are now described as follows:
In the mountainous area, Yuchuan Chuanxiong is bred from the stem sections of the stem. The stem section is called "Zizi" and it should be cultivated in the mountains about 1200m above sea level (mainly to prevent degradation). The land for childbirth can be used as a relic, but it cannot be done continuously. In mid-January, tubers were cut from the Chuanxiong to remove stems, leaves, soil and fibrous roots and transported to the mountains for planting. This tuber is called "cocoon".
Planting period: generally before and after the beginning of spring. The nests are 24cm in width and 7cm in depth. The large strokes can be cut into 2 to 4 blocks, one for each nest, one for each middle nest, and two for each nest. The bud mouth is up, press firmly and then apply compost, cover soil and flat.
Addressing field management: emergence before and after convulsions. In the end of March or the beginning of April, sparse seedlings are planted. Each litter is selected to have 8 to 10 stalks of uniform thickness and well-developed stalks. The remainder is cut from the stem base. After sparse seedlings, weeding and weeding were carried out before and after Gu Yu and once again. The cultivator should be shallow, and the top dressing should be mixed with human and animal manure water and oil cake meal.
Harvesting of medlar: In the middle or late July, choose a cloudy or sunny day to harvest the rake in the morning, dig up the entire plant, and remove the plants that are rotted from the pests and tubers. Remove the well-grown plants from the tubers (for medicinal purposes after drying), leaves and stem tips, tie them into handles, select shades, lay a layer of thatch on the ground, stack the stalks alternately on top, and cover them with thatch . Liqiu was taken out and cut to a length of about 4.5cm. There was a short section of the knot, which was "dumplings." According to the size and location of the stalks, the scorpions are divided into 7 categories: big dynasty, big mountain system, 正山系, 细山系, 纤子, 软软子 and 土苓子. It is better to have a positive mountain system and a big mountain system. After grading, it is transported to the mountains for planting. All kinds of medlars must be planted separately, and emergence and growth are more orderly.
The selection of plots, planting time, and the growth of tubers of the seeds of Chuanxiong are fast, and it is better to choose the soil with deep soil, loose texture and fertile soil, no autumn water, and good ventilation and air permeability.
The suitable period for planting is early in August each year, and it cannot be later than the end of August. Before planting, we must choose the scorpions that grow thickly, individualally complete, or in the mountains. Choose sunny when planting.
Rational application of base fertilizer to apply fertilizer Chuanxiong is a kind of fertilizer-tolerant plant. Applying basal fertilizer, reasonable dressing is one of the important measures to increase the yield. Top dressing is usually carried out several times. Firstly, before turning the ground, use 150kg of oil per acre, mix and grind the livestock manure with 4000~5000kg, spread it evenly on the surface and turn it into the soil as a base fertilizer. After each cultivator, topdressing is required to mix human and animal manure water with oil cake or ammonium sulfate. After the third application of fertilizer, but also with soil, grass ash, oil cake, calcium superphosphate and mix well, sprinkle in the crotch. This fertilizer should be before the frost, otherwise the fertilizer effect is not high. After returning green in mid-January of the second year, spring fertilizer should be applied once again in the end of February or the beginning of March.
About 20 days after planting the cultivating and weeding furrows, the seedlings are released and the cover grass is removed. Within 60 days after planting, weeding and weeding were conducted three times, once every 20 days. The first depth of about 6cm, the second depth of about 3cm, the third time only slightly plough the soil surface to remove weeds. In combination with weeding, the fine soil in the ditch is cultivated together onto the ridge surface. When the first secondary cultivator fills seedlings.
In January of the following year, the stems and leaves have been wilted. The stems and leaves should be removed first, and weeding and weeding should be carried out once again, and the rows of soil should be tied to the ridge to protect the tubers.
Pest control pest control: Chuanxiong pests are mainly stem borer moths, their generations of larvae from the leaf sheath into the stem, bite the plate. Can be stored in the lice, with 100 to 150 times the water injection of trichlorfon prevention, but also before planting, in addition to a strict selection of wolfberry fruit, with cigarette bones and willow leaves 5 ~ 6kg, add water, 50kg, after a total of cook Soak cold soaked oysters for 24 hours, or add about 150 times more water with trichlorfon and soak the medlar for 1 hour before planting.
Disease prevention and treatment: The diseases of Chuanxiong mainly include tuber rot disease, and local medicine farmers call it "water melon." Strictly remove diseased plants and pay attention to field seeding when digging and stalk harvesting.
In order to increase economic income, interplanting can be used to interplant wheat in the Sichuan-Yunnan area without any additional management.
Harvesting and processing methods of harvesting: Chuanxiong is harvested from Xiaoman to Mang in the second year after planting. Select the sunny day, use a double-toothed pickaxe to dig up the plant, shake off the dirt, remove the stems and leaves, lightly dry in the field, put the tuber in a bamboo crash, hit the soil, and return it to dryness.
Processing methods: Chuanxiong is usually dried with a bake, firepower should not be too large, turning 2 or 3 times a day. Remove the semi-dry tubers and hit them once. In the renewal process, fresh tubers are placed in the lower layer and semi-dry products are placed in the upper layer. After the upper part has been fully dry, it is divided into upper and lower layers and hits one time. Except for the net sediment and fibrous roots, the dry ones are selected as finished products. The dried ones are placed in the upper layer and continue to dry, so that they are turned daily until they are completely dry. In addition, store it in a dry place to prevent mold and insects.

Cardiovascular Drugs refers to Prescription drugs and medicines for diseases relating to the structure and function of the heart and blood vessels. Studies in these areas include: heart failure, coronary artery disease, high cholesterol, blood clots, circulation disorders, and others. A wide range of medications are used to treat various heart conditions. Some examples of the drugs used in cardiovascular medicine include:

Anticoagulants or blood thinners - These agents prevent coagulation or clotting of the blood. Injectable forms of anticoagulants include dalteparin, enoxaparin, tinzaparin and heparin. Warfarin is a commonly used Blood Thinner that can be taken in the form of a tablet. These drugs do not dissolve existing blood clots but are preventive agents in patients who have had a heart attack.
