How to plant Bupleurum to grow well?
Bupleurum is a perennial herb in the family Umbelliferae, which is used as a medicine by its roots, and is a variety of traditional Chinese medicine with great market demand.
With the increasing social demand and the growing scarcity of wild resources, the market gap is getting bigger and bigger, and the market prospect of home grown Bupleurum is very broad. Home grown Chaihu is mainly live in the spring.
The following is an introduction to its planting method. First, the selection of land rectification Chaihu sex like warm, moist environment, cold, drought resistance, afraid of waterlogging.
In production, it is advisable to choose fertile, loose, not waterlogged fields or gently sloping mountainous areas for planting. Where sticky, waterlogged (stained), thin soil plots should not be planted.
After the land is selected, each mu into 2500 kg of farmyard manure, 50 kg of calcium superphosphate, potassium sulfate 20 kg to do the base fertilizer, deep plowing 30 cm, leveling rake fine, do 110 cm wide flat bed. The area with a lot of rain can do 130 cm of raised beds, dug good drainage ditches around the beds.
Second, germination Chaihu seed germination on the temperature requirements are strict, the best temperature for germination for 18 ℃ ~ 22 ℃, more than 25 ℃ difficult to germinate. Chaihu germination takes a long time, 20 ℃, up to 50% germination takes 20 days.
Therefore, whether the planting season is properly arranged, directly related to the success or failure of planting. China's vast territory, the temperature difference between the north and south in the spring is very large, the growers can be arranged according to the local temperature of the ground planting.
For example, a region up to 18 ℃ ~ 22 ℃ ground temperature time around April 20 around the time, then April 1 around the time of germination. Before germination, the first seed immersed in 40 ℃ ~ 50 ℃ of warm water soaked for 4 hours ~ 6 hours, fishing floating in the water surface of the deflated seeds, the bottom of the full seed and clean river sand according to the volume ratio of 1:2 mix, placed in the open ceramic containers or pits of germination, temperature control in 18 ℃ ~ 22 ℃.
20 days or so, 1/3 of the seeds "white" can be sown. The amount of seed used per mu is 2 kilograms to 3 kilograms.
Third, sowing In the rectified beds, along the ridge direction to open four 10 cm wide ~ 15 cm, 1-5 cm deep shallow ditch, watering, the germination of seeds evenly sprinkled in the bottom of the ditch, covered with fine soil thickness of 0-2 cm ~ 0-3 cm, cover the grass heat preservation and moisturizing. 3 days ~ 5 days, one after another, seedling emergence.
Seedlings up to 60%, remove the cover grass, such as the border is too dry, can be sprinkled with water to create moisture, but also watering, to wait for flush seedlings. Fourth, field management After the seedling, pay attention to drought protection.
Pulling up the grass to eliminate the desert. Seedling height 5 cm time seedlings, plant spacing 5 cm.
After the seedlings, hoeing "squatting seedlings". When the leaves become thick, leaf color green, 10 kilograms of urea per mu, and watering a thorough watering.
Later on, watering is restrained, diligent hoeing to extinguish the desert. Before the rainy season, sprinkle 20 kilograms of diammonium phosphate per mu and water.
The rainy season should be strictly prevented from waterlogging and waterlogging in the field. Waterlogged fields are very likely to cause root rot disease, resulting in a significant reduction in yield.
Before freezing, watering a wintering water, sprinkle 3000 kilograms of pounded farmyard fertilizer per mu. Early spring of the next year, sow the dry stems and leaves on the ground, watering water.
When the seedling height of 12 cm ~ 15 cm, each mu ditch into 25 kg of diammonium phosphate, potassium sulfate 8 kg, watering after the application of a thorough watering. Later on, control watering, and strictly prevent waterlogging (impregnation).
In May, Chaihu successively draw shoots and flowers. In addition to the seed field, it should be cut in time to avoid unnecessary consumption.
V. Pest control Chaihu see root rot disease, due to high temperature and humidity, field accumulation (water) and hair. The onset of the plant green and yellow, and then dry and die, pulling out the visible root rot.
In addition to heavy application of phosphorus and potassium fertilizer, but also to improve the rainy season drainage, do not make the field waterlogged, the onset of the early stage of 50% carbendazim 1000 times liquid or 70% metribuzin 1000 times liquid irrigation plants. The insect pests of Chaihu are common in the spring seedling aphids, which can be killed by "pouncing aphids" and so on.
Sixth, harvesting and processing After sowing in late October of the second year, harvesting above ground stems and leaves, remove the old stalks, drying, bundled into a handful, that is, for the soft Chaihu (seedling Chaihu). Along one end of the border, carefully dig out the root strips, shake off the soil, remove the residual stems and leaves, and dry in the sun to become a commodity.
Dried Chaihu is best when it is dry, with long roots and no impurities. Generally mu yield 150 kilograms of Chaihu root, 150 kilograms of soft Chaihu.
Growing Bupleurum, reasonable dense planting, heavy application of phosphorus and potassium fertilizer, playing flower shoots, and preventing the occurrence of root rot are the main measures to increase production.
When is the best time to plant Chaihu
1, Chaihu is mainly seed propagation, generally can be sown in the winter and spring seasons, but the winter sowing is good, early spring seedlings and Qi, winter sowing is suitable for November to early December, Chaihu sex like warm, moist environment, cold, drought resistance, afraid of waterlogging.
Production should choose fertile, loose, not waterlogged field or gently sloping mountain planting. Where sticky, waterlogged (stained), thin soil plots should not be planted.
2, choose sandy loam or humus soil hillside terrace cultivation, should not choose clay soil and easy to waterlogged lot planting. If the seed is sown in the reclaimed wasteland, the stones in the field should be removed.
Branches and so on. After the land is selected, each mu into the farmyard fertilizer 2500 kg, 50 kg of calcium superphosphate, potassium sulfate 20 kg to do the base fertilizer, deep plowing 30 cm, leveling rake fine, do 110 cm wide flat bed.
The areas with high rainfall can do 130 cm of raised beds, dug good drainage ditches around the beds. 3, before germination, the first seed immersed in 40-50 degrees of warm water soaked for 4 hours ~ 6 hours, fishing floating in the surface of the deflated seeds, the bottom of the full of seeds and clean river sand according to the volume of 1:2 ratio of mixing, placed in an open ceramic containers or pits to germinate, the temperature is controlled at 18 ~ 22 degrees.
20 days or so, 1/3 of the seeds "white" can be sown. Mu with the amount of seed 2 kg ~ 3 kg.
4, in the rectified bed, along the ridge direction to open four 10 cm wide ~ 115 cm, 1.5 cm deep shallow ditch, watering, the germination of seeds evenly sprinkled in the bottom of the ditch, covered with fine soil thickness of 0.2 cm ~ 0.3 cm, cover the grass heat preservation and moisturizing. 3 days ~ 5 days, one after another, seedling emergence.
Seedlings up to 60%, remove the cover grass, such as the border is too dry, can be sprinkled with water to create moisture, but also watering, to wait for flush seedlings. Introduction: First, Chaihu, the name of traditional Chinese medicine.
For the "Chinese Pharmacopoeia" included in the herb, medicinal parts for the umbelliferae plant Chaihu or narrow-leaved Chaihu dry root. It is harvested in spring and fall, and then dried by removing the stems, leaves and sand.
Bupleurum is a commonly used antidote. Alias ground smoked, mountain vegetables, mushroom grass, firewood grass, bitter flavor, slightly cold, attributed to the liver, gallbladder meridian.
It has the effect of relieving the exterior and the interior, dredging the liver and elevating the yang. It is used for cold and fever, cold and heat, malaria, liver depression and stagnation of Qi, chest and rib distension and pain, prolapse of anus, uterine prolapse, menstrual disorders.
Second, pay attention to the problem: 1, the choice of seeds, usually choose the year of picking, and full of seeds is better, especially also pay attention to the scientific preservation, pay attention to the absence of pests and diseases, otherwise it will also affect the germination rate of the situation. 2, the treatment of germination, will be selected to put the seed of Chaihu about 35 degrees of warm water soaked for two hours, and then remove the floating seeds on the water surface, the rest of the seeds can be sown by drying.
3, the choice of soil, the selected land for a deep ploughing, it is best to apply a certain amount of fertilizer, whether it is farmyard manure or cattle and sheep manure are available, to better ensure the degree of soil fertility, and then harrowing treatment to ensure that the soil is loose on it. 4, seed sowing, the land in accordance with the 20 cm row spacing furrow, to ensure that the depth of 1.2 miles or so can be, and then the firewood seeds evenly sprinkled to the inside, covered with a layer of thin soil, watered with some water, if there are conditions can also be covered with some grass, to better keep the soil moist degree.
5, the problem of nurturing, because the early has solved the problem of soil fertility, the late maintenance is mainly to observe the moisture and timely watering on it.
Chaihu planting time when the most appropriate
1, Chaihu is mainly seed reproduction, generally can be sown in the winter and spring seasons, but the winter sowing is good, early spring seedlings and Qi, winter sowing in November to early December, Chaihu like warm, moist environment, cold, drought, afraid of waterlogging. Production should choose fertile, loose, not waterlogged field or gently sloping mountain planting. Where sticky, waterlogged (stained), thin soil plots should not be planted.
2, choose sandy loam or humus soil hillside terrace cultivation, should not choose clay soil and easy to waterlogged lot planting. If it is sown in the reclaimed wasteland, the field should be cleared of stones. Tree branches, etc. After the land is selected, 2500 kg of farmyard manure, 50 kg of calcium superphosphate and 20 kg of potassium sulfate are applied per mu as basal fertilizer, and 30 cm of deep plowing is done to level and harrow, making a 110-cm wide flat bed. The area with a lot of rain can do 130 cm of raised beds, dug good drainage ditches around the beds.
3, before germination, the first seed immersed in 40-50 degrees of warm water soaked for 4 hours ~ 6 hours, fishing floating in the water surface of the deflated, the bottom of the sunken full of seeds and clean river sand according to the volume of 1:2 ratio of mixing, placed in the open mouth of the ceramic containers or pits to germinate, the temperature is controlled in the 18 ~ 22 degrees. 20 days or so, there are 1/3 of the seed The temperature is controlled at 18~22 degrees Celsius. 20 days or so, 1/3 of the seeds can be sown when they are "dew white". Mu with the amount of seed 2 kg ~ 3 kg.
4, in the rectified bed, along the ridge direction to open four 10 cm wide ~ 115 cm, 1.5 cm deep shallow ditch, watering, will germinate seeds evenly spread in the bottom of the ditch, covered with fine soil thickness of 0.2 cm ~ 0.3 cm, cover the grass heat preservation and moisturizing. 3 days ~ 5 days, one after another, the seedlings. Seedlings up to 60%, remove the cover grass, such as bed too dry, can sprinkle water to create moisture, but also watering, in order to wait for flush seedlings.
Introduction:
First, Chaihu, the name of Chinese medicine. For the "Chinese Pharmacopoeia" included in the herb, medicinal parts for the umbelliferae plant Chaihu or narrow-leaved Chaihu dry root. Spring, fall two seasons to dig, remove the stem and leaves and sediment, dry. Chaihu is commonly used as an antidote to the symptoms. It is also known as ground fumigation, mountain vegetable, mushroom grass, firewood grass, bitter flavor, slightly cold, attributed to the liver, gallbladder meridian. It has the effect of relieving the exterior and interior of the body, dredging the liver and elevating the yang.
