When planting the Chinese herbal medicine Rehmannia, what are its planting requirements?

Rehmannia is a kind of traditional Chinese medicine, for the cultivation of Rehmannia, Rehmannia has relatively high requirements for the environment, Rehmannia needs sufficient sunlight, high-quality soil, and requires skilled cultivation technology. <>

Let's first briefly introduce Rehmannia Rehmannia, Rehmannia is a perennial herbaceous plant, its color is yellow, its color is generally purple-red, the flowering period is four to seven months, Rehmannia flowers generally bloom in summer, its flowers are generally larger, and appear light reddish-purple. If you want to plant rehmannia at home, when rehmannia blooms, it will also become a beautiful scenery in the family, and the ornamental value is relatively strong. Rehmannia generally grows on mountain slopes at altitudes of 50 to 1,100 meters.

Of course, where artificial planting is made, the requirements for the site are not particularly high. <>

Secondly, let's talk about the cultivation technology of Rehmannia rehmannia, Rehmannia is a plant that likes loose and fertile soil, and it is best to be sandy soil, when planting Rehmannia rehmannia, we should choose a sunny place when planting Rehmannia rehmannia, do not plant Rehmannia in the shade or where there are tall plants, Rehmannia seedlings are between 25 and 28 The most suitable for germination, the growth rate is also the fastest, about 15 to 20 days after germination, generally speaking, the growth and harvest cycle of planting Rehmannia generally takes between 150 and 160 days.

Artificially planted rehmannia is topdressed once after each tillage. It is best to use organic fertilizer for fertilization, and it is necessary to pay attention to planting rehmannia to prevent waterlogging and do not let the rainwater be stored in the roots of rehmannia for a long time, which needs to be paid attention to, otherwise it will lead to the decay of the follow-up place, but it can not be overly dry, if you do not water rehmannia for a long time, rehmannia will wither. <>

At the same time, we should also pay attention to the damage of pests and diseases. Generally speaking, rehmannia has diseases and insect disasters such as rehmannia wilt, soybean nematode, etc., in the insect pest season, 40% of water amidophos and trichlorfon and other drugs should be used for control.

Rehmannia is a plant with a not very developed root system, and Rehmannia likes water and sun, so when planting, we must choose sandy soil with good drainage, and not choose places with poor drainage such as yellow mud, and ensure sufficient sunlight and water.

Rehmannia is in traditional Chinese medicine, there are still a lot of medicines, and the area of planting Rehmannia in China is also very large, and the planting of Rehmannia should be selected in a sunny place, and the location of the region should be relatively flat and fertile.

It is best to choose a fertile, well-drained sandy loam soil. 2000-3000 kg of compost and 2500 kg of superphosphate are applied as fertilizer per mu.

Rehmannia is a light-loving plant. In general, wild rehmannia also grows on sunny hillsides and massifs. The choice of planting site is the basic condition for the high yield of Rehmannia rehmannia, so we can choose the planting site according to the growth habit of Rehmannia rehmannia.

It is best to be able to plant in plots with sufficient sunshine, good water storage and drainage, loose and dry soil texture, and rich organic matter.

Expose the roots inside and remove them one by one. The freshly dug root can be used as fresh rehmannia in the market**, if it is to be processed into rehmannia, it must be baked and baked out of dry rehmannia; Rehmannia also needs to be distilled with raw rehmannia and rice wine, and then dried. After the emergence of seedlings, it should be watered less, and it is advisable to keep the loess, and the principle of watering the rehmannia is three watering, and three watering is:

Drought resistance watering before emergence, watering after fertilization, drought and no rain for a long time, and watering at noon when the plant withers. Three do not water, do not water, do not water if the weather is not dry, do not water when the temperature is high at noon, the ground temperature is low, and do not water when the weather is cloudy and rainy.

Stagnant water should be removed in time after rain or watering. Rehmannia is generally planted in mid to late March. When planting, cut the roots and stems of Rehmannia into small pieces of about 5 cm.

Each segment has more than 2 eyes, and the ends of the incision are dipped in vegetable ash. Rehmannia has high requirements for water, different growth times have different water requirements, the initial growth of water requirements is larger, to water frequently, keep the soil moist, the later underground root expansion period, less water requirements, keep the soil dry, but also to prevent waterlogging and root rot after rain.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

To choose the right variety, in the planting process must be put in water soaked in water for about two days, and then to choose fertile and well-drained soil, to choose the right time, you can choose to plant in April, planting must pay attention to density and depth, and then the temperature in the planting process should be controlled at about 23 degrees, to water in time, do a good job of insecticide and weeding.

Rehmannia should be planted in a place with relatively flat terrain and sufficient sunlight, and at the same time, the soil should be relatively fertile, the water should be sufficient, and chemical fertilizers should be applied and watered appropriately.

Buy the seeds of Rehmannia and then find a piece of fertile soil, dig a pit in the soil, put in fertilizer, add water, and put in the seeds.

Generally, the requirements for the soil are relatively high, the need for fertile soil, and the drainage is also relatively good, generally in the planting to keep a distance of about 40 cm, and planted, after the weeding, fertilization and watering, but also appropriate pesticides to prevent pests.

First of all, seedlings should be raised first, and then planted when they grow to a certain stage, which can also improve the growth rate of rehmannia and have certain medicinal value.

First of all, Rehmannia prefers sunny, dry, warm climates; It has poor adaptability to soil, and should grow in neutral or slightly alkaline sandy loam soil with deep soil layer, loose soil, rich humus and high terrain, which can drain energy for irrigation, while clay soil does not grow well. Rehmannia reproduces mainly through rhizomes.

Soil: Rehmannia prefers fertile soil and generally chooses sandy soil for planting. Moisture:

Usually you should water less, the soil is in the best state of moisture, and in the rainy season, you should drain water in time to prevent waterlogging. Nutrients: After cultivating, it should be fertilized once, using chicken, duck, pig manure and human manure.

Introduction: Rehmannia itself is a traditional Chinese medicinal material in China, and it has a good ornamental value. Because from the outside, it blooms very beautifully.

In early summer, lilac flowers bloom. Therefore, the planting base seems to be a sea of flowers, and for those who like flowers, they can have a better experience. There are also those who have special hobbies and prefer to grow some plants of traditional Chinese medicine, so you can choose Rehmannia at this time.

By checking the relevant information, it is possible to find out when he was planted, mainly in mid-April. This ensures that some of his nutrients can meet his basic needs, and at the same time, his habit is to prefer loose and fertile soil, and those sticky red soils are not suitable for planting. Because it is a favorite plant, it is not possible to get close to tall crops.

Because this will lead to malnutrition, when the soil temperature reaches about 11 degrees, it is also more suitable for germination.

Morphological characteristicsThe morphological characteristics of Rehmannia rehmannia, which itself is a herbaceous plant, its height is about 30 cm, and its roots will have a lot of fine hairs. And the flesh of the rhizome is very thick, it has a red color. And under the conditions of cultivation it can reach centimeters in straight lines, and its stems are purplish-red.

Therefore, it has a very good appreciation value, and he often grows on some barren mountains at high altitudes.

Control measures: Like these medicinal materials, it also has some prevention and control measures, because each kind of medicinal materials may have some pests and diseases in its own growth period, and some pesticides are used to prevent it. Like those who have adopted his brother and colonists, he can choose some disease-resistant varieties and then spray them with Bordeaux liquid spray at the beginning of the disease. Because in this way, it can ensure that Rehmannia can grow normally, mainly because of those cotton-red spiders, pesticides can be used during the occurrence period.

First of all, it is necessary to choose a deep soil layer, well-drained fertile soil, deep ploughing Yuqing soil, applying foot fertilizer, regular fertilizer and water management, intermittent dismantling and seedling replenishment, cultivating and weeding, preventing pests and so on.

After planting them in the soil, there should be a very good spacing, and the soil should be a little fertile, and it should be watered and fertilized frequently, and their growth should be observed in a timely manner, and some pests and diseases should be prevented, and it is best to plant them in some sunny places. Pure width.

In the process of planting, we must choose high-quality soil, and then we also need to ensure the fertility of the water and soil with Henai, and then we also need to water in time after the acre, and Zen Lu also needs to be insecticidal and sterilized in time, and then we need to loosen the soil in time, and it is necessary to ensure temperature and humidity.

When planting, you should choose some flat terrain, and you should choose some more fertile soil, in the soil to have enough nutrients, at this time Tanchai potatoes must be fertilized more, and should also be watered a lot, with good drainage to grow particularly well.

First select some excellent rehmannia seedlings, and then choose a piece of fertile soil, Bi Sui is digging a few pits, put seedlings in the pits, cover with soil, water more, fertilize, spray pesticides.

The way to plant Rehmannia is to first choose a piece of land that is suitable for the feast of filial piety, and then fertilize the land, and then carry out the planting of Rehmannia Youhuang, and after the planting is completed, the land should also be topdressed, and the growth temperature and humidity of Rehmannia should be guaranteed.

Soil selection and preparation should be selected for deep, fertile, well-drained loam and sandy soils, and deep digging of the soil with Huangxi fertilizer in the winter or early spring of the previous year. In addition to the application of sufficient basal fertilizer, 100 kg of superphosphate and 30 kg of rotten cake fertilizer were applied per mu after reclamation to promote the development and expansion of rhizomes. When you close the pipes, sprinkle a quarter of an inch of fire dust between the pipes.

When planting yellow soil, choose a soil with strong air permeability, good moisture, deep soil layer, soft and fertile, which is very beneficial to the growth of root tubeers. Rehmannia planting plots should be applied with 2000-3000 kg of decomposed compost at the same time. The cultivation method of Rehmannia is introduced from the following aspects:

Soil selection and soil making. > Rehmannia is suitable for growing in sandy soils with mild climate, abundant sunshine, good drainage and irrigation, deep soil layer, and fertile and loose soil (can not be planted in lowland waterlogged; Adhesive mulch film technology is used in many places). Due to the high soil temperature, good water retention effect, fast emergence of glutinous rehmannia seedlings, prolonged growth period, and the yield increase is generally more than two times, which is worth promoting, and can be sown first and then mulched. From September to November of that year, the rehmannia stopped growing and was ready to be harvested.

Cut off the stems and leaves of Rehmannia and dig carefully. Do not cut rehmannia.

to avoid root breakage. Remove sediment and debris, i.e. cover the grass mud with fresh waxy rehmannia roots. Once rehmannia has been planted and covered with soil, straw or other propagation methods can be used:

Mainly used for vegetative propagation of tuber roots, MAS can also be used for seed propagation, but not usually for production. It is commonly used for breeding, but usually reaches cal8451 at average daily temperatures; Planting is the right time to plant. For example, the planting technique commonly used in early spring in Henan Province and the Muda rehmannia.

Before planting rehmannia, it is necessary to penetrate deep into the soil, fertilize and sow seeds, and in case of emergency to strengthen water and fertilizer management, and the costs and benefits of planting smallpox pollen are mainly roots. Raw and cooked soil can be obtained by different processing methods. This is a kind of cool rehmannia rehmannia, but people who grow glutinous rice don't know it, so today I will give you a brief introduction to the technology of planting glutinous rice after planting rehmannia rhizomes, which requires a certain temperature for germination; about ten days; in the blood of the drug.

Introduction: After the new crown epidemic, China's traditional Chinese medicine industry began to develop vigorously, and more and more people feel that the profession of doctors is more important, especially in the traditional Chinese medicine industry, because the traditional Chinese medicine industry has appeared a phenomenon of green and yellow, and many farmers do not understand the planting of some Chinese medicinal materials, so they do not dare to plant rashly, for fear of losing money. The emperor is a very important Chinese medicinal material.

1. Rehmannia rehmannia. Rehmannia is a kind of rehmannia that can reach a height of 30 centimeters, and the leaves of myopia purple are oval, and its flowers are sometimes purple-red, sometimes yellow, and generally grow on the slopes of mountains and on both sides of roads at an altitude of more than 100 1000 meters. He can be seen in many provinces in our country, he prefers to grow on some fertile sandy soil, but can not be planted on paddy soil, rehmannia is a plant that likes sunlight, generally grows on the leeward slope, rehmannia is mainly sown in spring.

Second, the characteristics of rehmannia

When planting rehmannia rehmannia, we must choose a flat terrain, the soil to be selected has a rich organic matter rotation period of 10 years, combined with the soil, each mu should be prepared to mix, Hefei to control the underground pest wilt and so on. During the planting process, the soil must be disinfected, and the ground pattern should be used to cover it in mid-April every year, and it must be used before planting rehmannia ground. Soak the seeds for 30 minutes and dry them before sowing them.

The method of weeding rehmannia uses chemical methods to sanitize it with herbicides. <>

3. Planting skills.

Rehmannia is very afraid of drought, waterlogging and pests, so in the whole growth process, farmers must pay attention to the early stage of rehmannia growth, the soil water content requirements are low, and the soil must be kept moist in the middle and late stages of growth, but there can not be too much water, because its root water absorption ability is very poor. In the course of the war, the average temperature of the day should be maintained, and at around 20, after the local yellow flowers have bloomed, it is necessary to choose a sunny day to pick them.
