Bupleurum planting

The planting cost of Bupleurum per acre

Bupleurum, also known as Northern Bupleurum and Xiao Bupleurum, is a plant of the Apiaceae and Bupleurum genus. It is a perennial medicinal herb. Bupleurum is a commonly used Chinese herbal medicine, and its roots are used as medicine. It has the functions of relieving the exterior and interior, reducing fever and opening yang, soothing the liver and relieving depression. Bupleurum has good antipyretic, analgesic and anti-inflammatory effects.

Habits: Bupleurum likes a warm and humid environment, has strong adaptability, can tolerate drought and is afraid of waterlogging, has strong winter tolerance, and grows best in Gaza land with fertile and loose soil. 1. Site selection and fertilization: Bupleurum is drought-tolerant and afraid of waterlogging. You should choose a sandy soil plot with higher terrain and better drainage. Combine it with deep plowing before winter, and apply 2,000 kilograms of high-quality organic fertilizer per mu. Apply again before sowing. 1,000 kilograms of high-quality machine fertilizer and 25 kilograms of compound fertilizer.

2. In order to save labor and effort in summer sowing, Bupleurum can be sown in summer, which does not occupy any land, saves labor, time and is easy to manage. According to the requirements of slow germination of Bupleurum seeds and long moisturizing time, summer sowing can be used. Intercrop sowing with corn. When the corn grows to 50 cm, directly sow the Bupleurum seeds into the corn field and cover them with 1 cm of soil. In this way, the natural conditions of corn shade, high temperature, high humidity and rain during the flood season can be used to ensure the germination and emergence of Bupleurum seeds. This experience has been accepted by the majority of Bupleurum growers and can be easily promoted.

3. Cultivating and weeding. Remove the grass cover in time after seedlings are sown in spring. Weed and loosen the soil according to the moisture content. Weeding should be done early, frequently and after rain to facilitate ventilation and temperature increase and promote the growth of root seedlings. In the second year, it is necessary to cultivate and weed 2-3 times. If the grass is cut in the first year and used as medicine, the decomposed compost should be stuck in the rhizosphere to protect the roots from freezing and protect the seedlings over the winter.

4. Fertilizer and water management. If the weather is dry after sowing, water and moisturize frequently until the seedlings emerge. After the seedlings are fully grown, topdress with 5 kg of decomposed manure or urea. Keep small amounts of fertilizer and large amounts of water, and open ditches for watering. When the seedlings grow to 30 cm high, topdress once.

Before flowering in early August, cut off the flower buds and topdress again to promote faster root growth. If the seeds are left and allowed to grow, it is best to topdress 1-2 times in the second year.

5. Thinning and replenishing seedlings. When the seedlings are 5 cm high, they can be thinned and transplanted. When the seedlings are 10 cm high, the seedlings can be checked and replenished by combining the seedlings (5-6 cm spacing between plants). 6. Prevention and control of diseases and insect pests Bupleurum root rot mostly occurs in high-temperature and rainy seasons, and can be mainly controlled in agriculture. It is best to rotate grass crops (avoid continuous cropping) and drain water promptly after rain; leaf spot disease mainly damages its leaves. Dark brown round lesions of 2-3 mm with a gray center appear on the head. In the early stage of the disease, 1:120 times Bordeaux mixture spray can be used to control it.

The main pests are yellow swallowtail butterfly and red oak, both of which can be killed manually. Use 90% trichlorfon 800 times solution, spray once every 5-7 days, and spray 2-3 times continuously.

7. Harvest at the right time. In October of the second year after sowing, after the upper part of the ground has withered and turned yellow, dig out the whole plant, remove the stems and leaves, shake off the soil, and dry it in the sun. If the whole grass is used, the stems and leaves can be cut in the autumn of the year of sowing (referring to spring sowing) and before the roots are harvested the following year, sorted into handfuls, and then the roots are dug up and dried separately for sale.

Benefit analysis: The growth period of Bupleurum is 1-2 years. If the conditions are suitable, it can usually be harvested in one year, with a yield of 100 kilograms of dry product per mu. The first-year-old ones have good quality and high saikosaponin content; the two-year-old ones have high yield, with a dry rate three times that of the first-year ones.

The dry product output per mu can reach more than 100-200 kilograms. According to the general market price of RMB/kg, the annual income per mu is RMB.

Production cost: chemical fertilizer yuan (including compound fertilizer yuan per mu, potassium sulfate yuan, superphosphate yuan) cultivated land yuan, watering land yuan, pesticide yuan, seed yuan, *** total investment yuan , excluding costs, the net benefit is more than 3,000 yuan per mu.

Bupleurum planting method and time

Choose soil with neutral or slightly acidic pH, moderate soil aggregate structure, 1%~1.3% organic matter content, sunny location, and deep cultivation layer , well-drained sandy loam, loam soil.

Apply 4,000 kilograms of livestock (poultry) decomposed fertilizer, stored green fertilizer or straw compost every 667 meters; 80 kilograms of bio-organic compound fertilizer; or 20 kilograms of nitrogen fertilizer and 50 kilograms of potassium sulfate. Before sowing, plow deeply to more than 20 centimeters, plow and rake finely, and create good base moisture.

From the end of July to the beginning of August, open a shallow trench between the rows of the previous crop, with a trench depth of 1 to 1.5 cm. Sprinkle the seeds evenly into the trench, cover with 1 mm of soil, and tread lightly after sowing. If possible, Covering the area with wheat straw can improve the seedling emergence rate. Once the fall crop is harvested, no other crops are grown the following year.

Before sowing, soak the seeds in warm water at 30~40℃ for 24 hours. After drying, add 3 parts of wet sand and mix well. Germinate at around 20℃ for 10~12 days. Use 2.5 to 3 kilograms of seeds per 667 meters.

What are the planting techniques and yield of Bupleurum?

Bupleurum is a perennial herbaceous plant of the Umbelliferae family. It is a traditional bulk medicinal material in my country. It is mostly supplied to the market as wild products. It is mainly produced in Liaoning, Jilin, Heilongjiang, Gansu, Hebei, Henan, Anhui, Shanxi, and Shaanxi. , Shandong, Jiangsu, Sichuan, Hubei, Inner Mongolia and other places.

After entering the 21st century, due to the large-scale mining of wild products year after year, the output has been declining year by year, while the output of domestic varieties is very small, and the market gap is increasing year by year.

Prospects for planting Bupleurum. The production of wild Bupleurum across the country has tended to be exhausted. However, the artificial planting scale is very small and the yield is very low. The market supply is deteriorating. After entering the 21st century, many large pharmaceutical groups (factories) in my country have developed products using Bupleurum. The demand for Bupleurum for nearly a thousand new drugs, special drugs and Chinese patent medicines is increasing year by year. The amount of Bupleurum exported to more than 120 countries and regions in my country is increasing at a rate of 15% every year. The markets of Hong Kong, Macao and Taiwan are also increasing year by year. Looking for goods from the mainland, and the quantity is considerable.

The demand for Bupleurum is also increasing day by day in my country's dotted medicinal material markets, medicinal material companies, pharmacies, decoction companies, traditional Chinese medicine hospitals, hospitals of integrated traditional Chinese and Western medicine, clinics, etc. The Bupleurum market contains business opportunities, huge potential, and bright prospects. There is a large potential for both output and price in the future. Bupleurum has attracted widespread attention from pharmaceutical factories, pharmaceutical companies, drug dealers and medical institutions. Therefore, it is urgent to develop Bupleurum production. Planting Bupleurum is a good variety for adjusting the agricultural planting structure in rural areas and for farmers to get rid of poverty and become prosperous. All localities should be market-oriented and develop Bupleurum cultivation according to local conditions. "Things that are rare are valuable." , as the supply gap of Bupleurum has increased year after year, and the contradiction between supply and demand has become increasingly acute, the price of Bupleurum has increased year after year.

The planting prospects and planting benefits of Bupleurum. The planting benefits of Bupleurum seedlings can collect 50 kilograms of seeds per mu in the second year, and increase to 100 kilograms in the third year. Each kilogram is sold in the market. The price is 60 yuan, and the income can be 9,000 yuan. In the third year, 100 kilograms of roots (dry goods) are plowed per acre, and the market price per kilogram is 85 yuan, and the income can be 8,500 yuan. The total income per mu of seeds and roots is 17,500 yuan. . The various costs per mu of land in 3 years are 300 yuan for land transfer, 150 yuan for Bupleurum seeds (2.5 kilograms per mu, 60 yuan per kilogram), 100 yuan for herbicides, and 1,950 yuan for labor and others. The total cost is 2,500 Yuan, the average net income per mu is 15,000 Yuan, and the average annual net profit is 5,000 Yuan.

Compared with planting other crops, the annual income per mu is increased by 4,500 yuan. The planting prospects and planting benefits of Bupleurum. Requirements for planting Bupleurum 1. Bupleurum likes warm and humid climate conditions, has strong adaptability, is drought-tolerant, and is afraid of waterlogging. Therefore, when planting, you should choose sunny and gentle farmland for cultivation. The soil quality is preferably sandy loam with good drainage and humus soil with deep soil layer. The soil pH is 6 to 7. It is better to use grass plants as the first crop and avoid continuous cropping.

2. Land preparation and fertilization for Bupleurum planting should follow conventional medicinal planting methods. 3. When planting Bupleurum medicine, pay attention to seed selection and seed treatment. Full, mature seeds (double-hanging fruits) should be collected from plants that are more than 2 years old.

Bupleurum seeds have a short lifespan and a low germination rate. Old seeds that are more than one year old are not easy to germinate and cannot be used. Seed treatment should be carried out before sowing. Soak the seeds with 100 mg/kg of gibberellin for 2 hours, take them out and dry them for later use.

The sowing method should be adapted to local conditions. The methods of seed direct seeding and seedling transplanting can be used for cultivation, either spring sowing or autumn sowing. The amount of seed used per acre is 2.5-3kg.

4. The loose soil and weeding, seedling thinning, seedling stabilization, top dressing, watering, topping and bud removal, pest control, harvesting and processing of Bupleurum planting are all carried out according to conventional medicinal field management methods.

How to plant Bupleurum to grow well?

Bupleurum is a perennial herb of the Apiaceae family, and its roots are used as medicine. It is a traditional Chinese medicine with great market demand.

With the increasing social demand year by year and the increasing scarcity of wild resources, the market gap is getting bigger and bigger, and the market prospect of home-grown Bupleurum is very broad. Bupleurum is mainly grown by direct seeding in spring.

The following describes its planting methods. 1. Site selection and preparation: Bupleurum likes a warm and humid environment, is cold and drought tolerant, and is afraid of waterlogging.

For production, it is advisable to choose fertile, loose, water-free large fields or gentle slope mountainous areas for planting. Plots with heavy soil, accumulated water, and thin soil are not suitable for planting.

After the land is selected, apply 2,500 kilograms of farmyard manure, 50 kilograms of superphosphate, and 20 kilograms of potassium sulfate per acre as base fertilizer. Plow deeply to 30 centimeters, level and rake finely, and make a flat border of 110 centimeters wide. . In areas with heavy rainfall, a 130 cm high border can be built, and drainage ditches can be dug around the border.

2. Germination Bupleurum seeds have strict temperature requirements when they germinate. The optimal temperature for germination is 18℃~22℃. It is difficult to germinate if it exceeds 25℃. It takes a long time for Bupleurum to germinate. At 20℃, it takes 20 days to reach 50% germination.

Therefore, whether the planting season is properly arranged is directly related to the success or failure of planting. Our country has a vast territory, and the temperature difference between the north and the south in spring is large. Growers can arrange planting according to the local ground temperature.

For example, if the ground temperature in a certain area reaches 18℃~22℃ around April 20th, germination can be initiated around April 1st. Before germination, soak the seeds in warm water at 40°C to 50°C for 4 to 6 hours, remove the deflated seeds floating on the water, and mix the plump seeds that have sunk to the bottom with clean river sand in a volume ratio of 1:2. Evenly, place in an open pottery container or soil pit for germination, and control the temperature at 18℃~22℃.

In about 20 days, when 1/3 of the seeds are "white", they can be sown. The seed quantity per mu is 2 kg to 3 kg.

3. Sow seeds on the finished border. Open four shallow trenches 10 to 15 cm wide and 1.5 cm deep along the border. Pour enough water and spread the germination seeds evenly on the border. The bottom of the ditch should be covered with fine soil with a thickness of 0·2 cm to 0·3 cm, and covered with grass to keep warm and moisturizing. After 3 to 5 days, seedlings will emerge one after another.

When 60% of the seedlings have emerged, remove the grass cover. If the border is too dry, you can sprinkle water to create moisture or water to wait for the seedlings to grow. 4. Field management After all the seedlings are gathered, pay attention to drought prevention and seedling preservation.

Pull weeds and eliminate wasteland. The seedling height is 5 cm, and the spacing between plants is 5 cm.

After thinning the seedlings, hoe the seedlings. When the leaves become thicker and turn dark green, apply 10 kilograms of urea per acre and water them once.

From now on, water more sparingly and hoe frequently to eliminate waste. Before the rainy season, spread 20 kilograms of diammonium phosphate per acre and water.

During the rainy season, we must strictly prevent water accumulation and waterlogging in the fields. Accumulated water and waterlogging in fields can easily cause root rot, resulting in significant yield reduction.

Before freezing, pour winter water once and spread 3,000 kilograms of finely pounded farmyard manure per acre. In the early spring of the next year, remove the dry stems and leaves from the ground and pour green water back into them.

When the seedlings are 12 to 15 centimeters tall, apply 25 kilograms of diammonium phosphate and 8 kilograms of potassium sulfate in ditches per acre, and water them once after application. Control watering in the future to prevent water accumulation.

In May, Bupleurum chinensis blooms and blooms one after another. In addition to leaving it for farming, it should be pruned in time to avoid unnecessary consumption.

5. Prevention and control of diseases and insect pests: Root rot is common in Bupleurum, which occurs due to high temperature and humidity, and accumulation of water in the fields. Infected plants turn green and turn yellow, then dry up and die. Root rot can be seen after being pulled out.

In addition to heavy application of phosphorus and potassium fertilizers, prevention and control methods must also ensure good drainage during the rainy season and avoid water accumulation in the fields. In the early stage of the disease, 50% carbendazim 1,000 times or 70% thiophanate methyl 1,000 times can be used Liquid irrigation plants. The most common insect pests of Bupleurum are aphids in the seedling stage in spring, which can be killed with "aphids" and other methods.

6. Harvesting and processing: In late October of the second year after sowing, harvest the stems and leaves on the ground, remove the old stems, dry them in the sun, and bundle them into handfuls, which is the soft Bupleurum (Miao Bupleurum). Along one end of the border, carefully dig out the roots, shake off the soil, remove the remaining stems and leaves, and dry them in the sun to become a product.

Dried Bupleurum is better if it has a dry body, long roots and no impurities. Generally, the yield per mu is 150 kilograms of Bupleurum root and 150 kilograms of soft Bupleurum root.

When planting Bupleurum, reasonable dense planting, heavy application of phosphorus and potassium fertilizers, cutting of flower sprouts, and preventing the occurrence of root rot are the main measures to increase production.

When is the best time to plant Bupleurum

1. Bupleurum is mainly propagated by seeds. Generally, it can be sown in winter and spring, but winter sowing is better because the seedlings will emerge early in spring. And Qi, winter sowing should be carried out from November to early December. Bupleurum likes a warm and humid environment, is cold and drought tolerant, and is afraid of waterlogging.

For production, it is advisable to choose fertile, loose, water-free large fields or gently sloping mountainous areas for planting. Plots with heavy soil, accumulated water, and thin soil layers are not suitable for planting.

2. Choose hillside terraces with sandy loam or humus soil for cultivation. It is not suitable to choose clay soil and areas prone to water accumulation. If sowing in reclaimed wasteland, stones should be removed from the field.

Branches, etc. After the land is selected, apply 2,500 kilograms of farmyard manure, 50 kilograms of superphosphate, and 20 kilograms of potassium sulfate per acre as base fertilizer. Plow deeply to 30 centimeters, level and rake finely, and make a flat border of 110 centimeters wide.

In areas with a lot of rain, a 130 cm high border can be built, and drainage ditches can be dug around the border. 3. Before germination, immerse the seeds in warm water at 40-50 degrees for 4 to 6 hours, remove the deflated seeds floating on the water, and mix the plump seeds that have sunk to the bottom with clean river sand in a volume ratio of 1:2. Mix well, place in an open earthenware container or soil pit for germination, and control the temperature at 18 to 22 degrees.

In about 20 days, when 1/3 of the seeds are "white", they can be sown. The seed quantity per mu is 2 kg to 3 kg.

4. On the finished border, open four shallow trenches with a width of 10 cm to 115 cm and a depth of 1.5 cm along the border direction. Pour enough water and spread the germination seeds evenly on the bottom of the trench. Cover with fine soil with a thickness of 0.2 cm to 0.3 cm, and cover with grass to keep warm and moisturizing. After 3 to 5 days, seedlings will emerge one after another.

When 60% of the seedlings have emerged, remove the grass cover. If the border is too dry, you can sprinkle water to create moisture or water to wait for the seedlings to grow. Introduction: 1. Bupleurum, the name of Chinese medicine.

It is a herbal medicine included in the "Chinese Pharmacopoeia". The medicinal part is the dried root of the Umbelliferae plant Bupleurum or Bupleurum angustifolia. Excavate in spring and autumn, remove stems, leaves and sediment, and dry.

Bupleurum is a commonly used anti-inflammatory drug. Also known as Radix Rehmanniae, Shancai, Mushroom Grass, and Chai Cao, they are bitter and slightly cold in nature and flavor, and belong to the liver and gallbladder meridian.

It has the effect of reconciling the exterior and interior, soothing the liver and promoting yang. It is used for colds and fever, alternation of cold and heat, malaria, liver stagnation and qi stagnation, chest and rib swelling and pain, anal prolapse, uterine prolapse, and irregular menstruation.

2. Issues to pay attention to: 1. When choosing seeds, it is usually better to choose seeds picked in the same year, and seeds with full particles are better. In particular, we must pay attention to scientific preservation and ensure that there are no diseases or insect pests. Otherwise, it will be the same. Will affect the germination rate.

2. For germination processing, soak the selected Bupleurum seeds in warm water at about 35 degrees for two hours, then remove the floating seeds on the water, and dry the remaining seeds before sowing.

3. Selection of soil. Carry out in-depth plowing of the selected land. It is best to apply a certain amount of base fertilizer. Whether it is farmyard manure or cow and sheep dung, it is acceptable. It is better. Ensure that the soil is fertile, and then harrow it to ensure that the soil is loose. 4. To sow seeds, dig the land with a row spacing of 20 cm to ensure a depth of about 1.2 miles. Then spread the Bupleurum seeds evenly inside, cover with a thin layer of soil, and pour some water. If If possible, you can also cover it with some grass to better keep the soil moist.

5. Regarding the problem of tending, because the problem of soil fertility has been solved in the early stage, the later maintenance is mainly based on observing the moisture and watering in time.
