How does the Radix Isatidis seed grow in the past few years?

How does the Radix Isatidis seed grow in the past few years to make Banlangen? Banlangen is a genus of grasses, blue scorpions, and is a genus of the genus Brassica. It is cultivated all over the country. Banlangen likes to warm the sunny environment, and the soil requirements are not strict. Drought resistance, cold resistance, avoid water accumulation. Banlangen is propagated by seeds, and can be used for live broadcast. Let's take a look at how to plant Banlangen seeds together!

During the planting season, the planting season is different, and the products harvested are different. According to the planting time of Banlangen, it can be divided into four stages: autumn sowing, early spring sowing, spring sowing, and summer sowing. The autumn sowing and early spring sowing are mostly for the purpose of harvesting seeds. The roots of these four periods are not able to be used as medicines;

Summer sowing is suitable for use in areas with long rainy seasons in the south. This method can reduce pests and diseases, but the yield is low. The spring-sown Radix is ​​the most commonly used method for both harvesting and harvesting, and high yield.

Before planting, Banlangen is a deep-rooted plant. It prefers a cool environment, is more resistant to cold, and is afraid of water accumulation. It is suitable for cultivation in North China and Northwest China. Some preparations should be done before the planting of Banlangen, which mainly includes land selection, soil preparation and fertilization.

It is suitable for planting in low-water groundwater, well-drained, loose and fertile sandy loam or river alluvial loam. The sapphire root planted on such land has high yield, good quality, labor saving, small investment and high economic benefits. Here we must pay special attention to the fact that when choosing the land, we must not choose clay and low-lying land, which is easy to cause the roots of the radix.

In addition, the land should be selected in the place where the leeward is sunny and close to the water source, which is convenient for daylighting and watering during the growth of Radix. The front crops of the selected plots are better with soybean meal or corn borer. If the selected plot is a slope, the slope should generally not exceed 15°. Drainage facilities should be well installed on the slope to prevent the loss of water, soil and manure and affect the growth and yield of Radix.

Fertilization: Apply base fertilizer before site preparation. The base fertilizer is best with decomposed pig manure, horse manure and sheep manure. It is forbidden to apply raw manure. Otherwise, it will produce high heat due to post-application fermentation and burn the roots of Radix.

In order to control pests, it is best to spray 90% trichlorfon 800 times in the process of manure accumulation and mix well to kill eggs, mites and larvae. The organic matter content of these fertilizers is high, and the nitrogen, phosphorus, potassium and trace elements are complete, which can not only meet the growth needs of Radix Isatidis, but also loosen the soil, improve soil structure and physical and chemical properties, and promote the growth and yield increase of Radix Isatidis. .

Apply 2000-3000 kg of fertilizer per acre; if the manure is sufficient, it can be applied to 4000 kg per acre. When the manure is insufficient, 50 kg of diammonium phosphate or superphosphate may be added per acre and 15 kg of potassium fertilizer such as potassium chloride or potassium sulfate may be added.

Site preparation: Since radix is ​​a deep-rooted medicinal crop, the root layer must be loose. Therefore, deep fertilization is required after fertilization. In order to ensure the growth conditions of the roots of Radix isatidis, the depth of the soil should be more than 30 cm, which is beneficial to the root extension, straightness, smoothness and no separation. In the land preparation, the sandy land can be turned slightly shallower, and the more viscous land can be turned slightly deeper. Finally, the clods will be broken and the land will be leveled. ?

After the plot is completed, it will be done. In the north, the area with less precipitation can be used for flatness, and the width is 1.5-1.8 meters. In the south, sorghum should be used to facilitate drainage. The height is 20-30 cm. Generally, the place with high terrain will be lower, and the place with lower terrain will be higher.

The length of the land can be determined according to the topography. The flat land can be used as a long raft, and the undulating land can be short. Leave a 30 cm wide work path between the two. Combine the bed to further break the clods, make the soil fine and broken, prevent the soil from mixing with the clods and debris, affect the germination and root growth of the Radix isatidis, and ensure the quality of the land preparation. The good standard for planting is that the surface is smooth and the soil is finely divided. After the whole land is finished, it will be planted.

Banlangen sowing

1. Seed selection: The seeds of Radix is ​​selected from the previous year, and the seed coat has black new seeds. Such seeds have good maturity and the germination rate can be guaranteed above 95%. Moreover, such seeds will not bloom in the same year after sowing; and if the seeds are stored for many years, not only the germination rate is low, but also easy to bloom in the same year, which affects the yield and quality of Radix isatidis.
2. Seed treatment: After the seeds are selected, in order to increase the germination rate of Radix isatidis seeds, the seeds are also treated before sowing. Soak the seeds in water for 12-24 hours. In this way, the grass clippings and scorpions mixed in the seeds of Radix isatidis can be removed, and the seed coat of the Radix isatidis seeds can be softened to facilitate budding. After soaking, remove and dry, then you can plant.
3. Sowing time: During the planting process of Banlangen, there are strict requirements for sowing time and sowing methods. Let us know the time of sowing. For the spring-sown Banlangen, the northern region is generally planted in early April, and the southern region can be appropriately advanced, but it is required to be planted when the local temperature is stable above 12 °C, which is conducive to deep rooting and prolonging the growing season.
4. Sowing: One week before sowing, water should be poured once to ensure the water needed for the roots of Radix Isatidis to germinate. There are many methods for planting Radix Isatidis, but the commonly used methods are both seeding and hole sowing. The striping adopts a line spacing of 30 cm, and the seeding amount is about 3 kg per mu; the seeding distance is 30×20 cm or 30×30 cm, and the seed amount is relatively small, and the amount is between 1.5 and 2 kg per mu.

The sowing depth is 3 cm. After sowing, it is covered with a layer of fine soil and covering soil. The thickness is about 1 cm. Finally, the mulch is covered with mulch to moisturize. Due to the large wind in the spring, in order to prevent the wind from blowing up the film, the film is covered on the surface of the concrete, and in addition to the surrounding soil pressure, the soil is also pressed in the center of the film. It should be noted here that since the seed topping of the Radix isatidis is weak, it is necessary to crush the soil between the two sowing ditch so as not to affect the germination of the seed.

After the seedling management board, the seeds of the blue roots are usually released in 7 to 10 days, and the seedlings can be produced in 15 days.

1. Venting ventilation: It is found that after the seedlings of Radix isatidis, the film on the seedling should be picked up in time, so that the seedlings can continue to grow upwards, and the seedlings can be prevented from burning at high temperatures. Therefore, the temperature at night is still low, so the ventilation holes cannot be opened too much, otherwise the seedlings will stop growing. The size of the ventilation holes is slightly larger than the seedlings. The tying membrane ventilation work is carried out every day, and it is continued until the seedlings on the sorghum surface are in line.
2. Weeding: During this period, due to the high temperature and humidity under the membrane, some weeds will grow rapidly, and the membrane will be broken. When the weeds are found to break out, it should be removed in time. In order to prevent the weeds from continuing to grow here, the hard clods are pressed at this position after the weeds are removed.
3. Intercropping: With the growth of the seedlings of Radix isatidis, in order to improve the ventilation and light transmission conditions of Radix isatidis seedlings, and to ensure the normal supply of nutrients, it is necessary to carry out a seedling when the seedlings grow to 5 to 6 true leaves, this time the seedlings should be small Stay big, go weak and stay strong, keep the seedling spacing between 5 and 8 cm. When the seedlings of Radix isatidis are 10 cm long, the second seedling is to be carried out. At this time, the seedlings are also the seedlings of the seedlings of the Radix Isatidis. Before the seedlings are fixed, the covering film on the surface of the sorghum is first removed, and then the cultivating is carried out on the glutinous rice noodles.
4. Secondary tillage: the medium tillage can change the permeability of the soil in the noodle soil, which is conducive to the preservation of the soil. Second, the cultivating is beneficial to the roots of the seedlings. Because the roots of the blue roots are not deep, the depth of the cultivating should be deep. Shallow should not be deep, 2 to 3 cm is appropriate. After the completion of the cultivating, the seedlings will be fixed.
5. Ding Miao: The spacing of the seedlings is 20 to 25 cm. The weeds should be removed at the same time as the seedlings are fixed. If the ridges are missing in the seedlings, the seedlings should be replenished in time. After the seedling work is completed, it is necessary to spray a 50% carbendazim WP 1000 times solution to prevent the occurrence of Sclerotinia.
6. Topdressing: After 3 days of film uncovering, the organic fertilizer should be applied once after the seedlings adapt to the environment. In the seedling stage, the nitrogen fertilizer is used, and the water is poured once after fertilization. Considering that the seedlings are still small at this time, the watering amount of the watering should be smaller, so that the surface is wet.

The planting effect and the prospect of Banlangen make money?

Banlangen is a kind of Chinese medicinal material, which is a dry root of the indigo plant indigo. It is usually harvested in autumn. It can be used in medicine after processing. It is produced in all parts of China. Let’s take a look at the planting benefits and planting prospects of Banlangen!

The radix is ​​suitable for climate and soil conditions. It is resistant to severe cold and warm, but it is afraid of water stains. It can grow normally in the Yangtze River Basin and the vast northern regions of China. The seeds are easy to germinate, and the germination is good in the range of 15C to 30C. The germination rate is generally above 80%, and the seed life is 1 to 2 years.

The normal growth and development process of Radix Isatidis must pass through the low temperature stage in winter, so that it can bloom and seed. Therefore, this characteristic is utilized in production, and spring or summer sowing is adopted. The leaves are harvested and the roots are harvested in the same year. The planting time is 5-7 months. If cultivated according to the normal growth period, it is only used for seed retention.

The blue roots of Radix isatidis are the genus Brassica, which is one of the commonly used bulk medicinal materials. In recent years, due to the increasing social demand, the price of sapphire roots has steadily increased. At present, the market for medicinal materials has been in short supply. The Chinese Medicine Administration recommended one of the 63 scarce Chinese herbal medicines to be developed.

Therefore, the prospect of artificial cultivation of Radix is ​​very promising, and the farmers can develop production according to local conditions. Banlangen is suitable for cultivation in all parts of China. It can be sown in spring, summer and autumn. It takes only 6 to 7 months from planting to harvesting, and can be used twice a year. It is a low-cost, fast-acting medicinal material. Take 1 mu of radix radicans as an example. :

1. Input: 2 kg of seed, 200 yuan of fertilizer, 100 yuan of fertilizer (50 kg of phosphate fertilizer, 20 kg of compound fertilizer, 10 kg of urea), 30 yuan of pesticides, herbicides, etc., totaling 330 yuan.

2. Revenue: Banlangen produces 250-350 kilograms of roots per year (up to 400 kilograms at high production). The current market purchase price is 20-25 yuan/kg. Calculated according to the lowest output and price, the output value is 250 kg×20 yuan/kg. = 5000 yuan.

3, pure profit: 5000 yuan -330 yuan = 4670 yuan.

Banlangen planting prospects Radix is ​​one of the most commonly used Chinese herbal medicines in China. It has the effects of clearing away heat and detoxifying, cooling blood and pharynx. Radix isatidis has the most obvious antiviral effect and is a good medicine for preventing epidemic diseases such as influenza, mumps, Japanese encephalitis and infectious hepatitis. Therefore, in the history, every time an outbreak or disease is discovered in various places, there is a figure of Banlangen.

Since the reform and opening up in China in the last century, the market of Banlangen has been greatly affected by various factors. For example, in 1987, Shanghai’s sudden epidemic infectious hepatitis, Banlangen rose from 2 yuan (kg price, the same below) before the incident. Up to 22 yuan high price;

The second time was in Guangzhou in the spring of 2003, when SARS was the most serious epidemic, when it was raised to more than 100 yuan in high time; the third time was when bird flu occurred in some parts of China in 2005, and the prescription was also dominated by Banlangen. It is not difficult to see that the brilliant history of Banlangen is closely related to the sudden outbreak.

Due to the obvious anti-viral effect of Radix isatidis, new products have been introduced in recent years, and sales of Banlangen have been increasing. The annual sales of Banlangen (except for SARS in 2003) have been around 15,000 tons in recent years.

The main raw materials for Banlangen are: Banlangen Granule, Banlangen Injection, Banlangen Syrup, Banlangen Tablet, Banlangen Lozenge, Banlangen Tea, etc. Among them, Banlangen Granule is well known, it is cheap, easy to take, obvious effect, no side effects. It is a good medicine for preventing colds in the early spring and autumn, and the sales volume is huge.

Banlangen is also used in veterinary medicine. With the continuous development of China's aquaculture industry, various diseases of livestock occur frequently, such as bird flu that occurred this year. The anti-viral effect of Banlangen is obvious, and the annual sales volume in veterinary use is also over 2,000 tons.

Warm reminder, Banlangen has seen a large number of abandoned or reduced seeds since 2004. There are two main reasons for this:

First, under the influence of national preferential policies such as grain price hikes and direct grain supplementation, farmers have abandoned food and medicine, and the area of ​​planted medicinal materials has decreased year by year;

Second, when the price of Banlangen is extremely high, the price of the market is difficult to rise, and the price changes are dramatic, sudden and slow. In addition, Banlangen is easy to change color, oil, and insects, and it is difficult to store for a long time. As a result, producers and operators will miss the opportunity every time the price fluctuates, especially the farmers in the production area are the hardest hit.

In view of the above reasons, the pharmaceutical industry predicts that the development of Banlangen has broad prospects. I hope to seize the favorable opportunity to develop Banlangen planting according to the GAP standard.
