Planting prospect of Radix Isatidis

Radix Isatidis, alias Indigo Root, Radix Isatidis, Radix Isatidis, is a kind of traditional Chinese medicine, which is the dried root of Isatis indigotica, a cruciferous plant. It is usually dug in autumn and can be used in medicine and produced in all parts of China. Let's take a look at the planting benefits and prospects of Radix Isatidis.

Planting conditions of Isatis root

Radix Isatidis has a strong adaptability to climate and soil conditions, resistant to cold, like warmth, but afraid of water stains, the Yangtze River Basin and the vast northern areas of China can grow normally. Seeds germinate easily, all germinate well in the range of 15C~30C, the germination rate is generally more than 80%, and the seed life span is 1-2 years.

The normal growth and development process of Radix Isatidis must go through the stage of low temperature in winter before it can blossom and seed, so in production, spring or summer sowing is adopted, the leaves are harvested and the roots are dug in the same year, and the planting time is 5-7 months. If cultivated according to the normal growth period, it is only used to keep the seed.

Planting benefit of Radix Isatidis

Radix Isatidis, a plant of the genus Cruciferae, is one of the commonly used bulk medicinal materials. In recent years, due to the increasing social demand and the steady rise in commodity prices of Radix Isatidis, the market of Radix Isatidis has been in short supply. Recommended by the State Administration of traditional Chinese Medicine as one of the 63 kinds of scarce traditional Chinese medicine. Therefore, the prospect of artificial cultivation of Radix Isatidis is very promising, and drug farmers can develop production on a large scale according to local conditions. Radix Isatidis is suitable for cultivation in all parts of our country. It can be sown in spring, summer and autumn. It takes only 6 to 7 months from seed to harvest, and can be replanted twice a year. It is a medicinal variety with low cost and quick effect. Take the planting of 1 mu of Radix Isatidis as an example:

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

2. Income: Radix Isatidis produces 250 kilograms of tuber root every year (more than 400kg in high yield). At present, the market purchase price is 20,25 yuan / kg. According to the minimum output and price, the output value is 250kg × 20 yuan / kg = 5000 yuan.

3. Net profit: 5000 yuan-330yuan = 4670 yuan.

Planting prospect of Radix Isatidis

Radix Isatidis is one of the commonly used bulk traditional Chinese medicine in China, which has the effect of clearing heat and detoxification, cooling blood and promoting pharynx. Radix Isatidis has the most obvious antiviral effect, and it is a good medicine for the prevention and treatment of epidemic diseases such as influenza, mumps, Japanese encephalitis and infectious hepatitis. Therefore, in history, whenever an epidemic or disease is found in various places, there is Banlangen. Since China's reform and opening up in the last century, the market of Banlangen has fluctuated greatly under the influence of various factors, such as the outbreak of infectious hepatitis in Shanghai in 1987. Banlangen soared from 2 yuan (kg price, the same below) to a high price of 22 yuan; the second time was Guangzhou, where the epidemic was most serious during SARS in the spring of 2003, and rose to more than 100 yuan when it was high. The third time was when bird flu occurred in some parts of China in 2005, and Banlangen was mainly used in the prescription. It is not difficult to see that the brilliant history of Banlangen is closely related to the sudden epidemic situation.

Due to the obvious antiviral effect of Radix Isatidis, new products have been introduced in recent years, and the sales volume of Radix Isatidis has been increasing. The annual sales of Radix Isatidis (except SARS in 2003) has been about 15000 tons in recent years. The drugs with Radix Isatidis as the main raw materials are: Radix Isatidis granules, Radix Isatidis injection, Radix Isatidis syrup, Radix Isatidis tablets, Radix Isatidis buccal tablets, Radix Isatidis tea and so on, among which Radix Isatidis granules are well known. it is cheap, convenient to take, obvious effect, no side effects, is a good medicine to prevent colds in the early spring, autumn and winter, and has a huge sales volume.

Radix Isatidis is also widely used in veterinary drugs. with the continuous development of China's aquaculture industry, various diseases of livestock occur frequently, such as bird flu this year. The antiviral effect of Radix Isatidis is obvious, and the annual sales volume in veterinary use is more than 2000 tons.

In addition, Banlangen has been abandoned or reduced substantially since 2004, which is mainly due to two reasons: one is that under the influence of national preferential policies such as rising grain prices and direct subsidies for growing grain, farmers have abandoned medicine to grow grain, and the area of planted medicinal materials has decreased year by year; second, the price is extremely high when Banlangen is brilliant, and it is difficult for prices to fall in bad markets, and the price changes are dramatic, sudden and slow. In addition, Radix Isatidis is prone to discoloration, oil and insects, so it is difficult to store for a long time. As a result, producers and operators will miss the opportunity every time of price fluctuation, especially the farmers in the producing area will be hit hardest.

In view of the above reasons, people in the pharmaceutical industry predict that the development of Radix Isatidis has broad prospects. Hope to seize the favorable opportunity to develop the planting of Radix Isatidis according to the GAP standard.
