Description

A kind of culture technique of Radix Isatidis

Technical field

The present invention relates to culture technique, relate in particular to a kind of culture technique of Radix Isatidis, belong to the planting technology field.

Background technology

Radix Isatidis (another name commonly used: indigo-blue, indigo root, manyflower glorybower root) is a kind of traditional Chinese medicine.All produce all over China.Radix Isatidis is divided into northern Radix Isatidis and rhizoma et Radix Baphicacanthis Cusiae, and northern Radix Isatidis source is the root of cruciferae isatis (Isatis tinctoria L.) and careless smalt (I.indigotica Fort.); Rhizoma et Radix Baphicacanthis Cusiae is rhizome and the root of acanthaceous vegetable acanthaceous indigo (Baphicacanthus cusia (Nees) Brem.).Effect with clearing heat and detoxicating, cool blood detumescence, relieve sore throat.

Radix Isatidis is the medicinal material that a kind of consumption is very big and long-term sales does not wane, and makes a general survey of the history of Radix Isatidis, and we can see that its sales volume is in growth at full speed.Sales volume is at 500,000 kg Radix Isatidis year before the sixties in 20th century; The many curative effects of the Radix Isatidis seventies determine that annual turnover is broken through 3,000,000 kg; To the mid-80, the purchase and sale amount reaches 8,000,000 kg; Annual production at the beginning of the nineties reaches 2,000 ten thousand kg, occurs that serious supply exceed demand; The mid-90, output was about 9,500,000 kg, and demand is about 8,000,000 kg, and the situation that supply exceed demand is not extenuated; After 2000, the cultivated area of Radix Isatidis to western part, the northwestward and northeast expanding species, causes 2002 annual productions to break through 3,000 ten thousand kg by the area, Central Plains, and the Radix Isatidis price reaches historical freezing point.SARS had spurred demand in 2003, but SARS has also stimulated the medicinal herb grower when consuming the stock plantation enthusiasm so that SARS later Radix Isatidis supply exceed demand becomes foregone conclusion.

In history, its price usually can cause demand to escalate suddenly because of epidemic disease.In Shanghai in 1989 and peripheral provinces and regions hepatitis B popular, pulling is to the demand of chromatogram of Radix Isatidis rapidly, the Radix Isatidis price is soared to 10～12 yuan/kg by 1.5-2 unit/kg, has greatly stimulated production.Surplus appearred in the whole nation in 1992, slided under the market price about 3 yuan/kg, fell into 2 yuan/kg of low ebb in 1993.Enter 1996, because the stock empties, price has a rebound again, rises to 6～7 yuan/kg in 1998, and price progressively descended in 4 years subsequently, and 2002 reduce as far as possible is 1.5-2 yuan/k.2003 because the SARS epidemic, Radix Isatidis is as the simply medicine that all has in various preventions and the treatment SARS proved recipe, and suddenly fast-selling, market price is unprecedented soaring, once created the high price of 100 yuan/kg April, and annual turnover is according to a preliminary estimate also about 1,000 ten thousand kg.SARS later Radix Isatidis price descends rapidly, and 6～December in 2003, price maintained 5～12 yuan/kg substantially.During Radix Isatidis in 2004 produced newly, the pharmacist began to hoard bulk production, replenished the stock, and waited for and improving price for the second time.A large amount of purchases make the Radix Isatidis price that rise slightly be arranged.But along with Radix Isatidis goes on the market in a large number, and SARS is controlled, and not recurrence makes Radix Isatidis immediately eclipsed, and the dream that Radix Isatidis hoarder secondary is made a good deal of money is thoroughly vanished, and begins a large amount of goods puttings, and the Radix Isatidis price is fallen back to rapidly about 4 yuan/kg.The Radix Isatidis price still was stabilized in about 4 yuan/kg in 2005.The market price of estimating Radix Isatidis will present the trend of slightly falling in steady, make sure to keep in mind not confused by the high price of during SARS, the blindly plantation of ground of jumping on the bandwagon, should because of the time, suitably develop production because of ground, because of the market demand.At present in Anhui, the province such as Shaanxi, Jiangsu actively setting up the isatis root GAP base, and the isatis root GAP base that the Taihe County, Anhui Province is set up is by first GAP ' authentication of base of national Bureau of Drugs Supervision, and the foundation in base will make the Radix Isatidis market price more steady.

Summary of the invention

The invention provides a kind of culture technique of very simple and convenient a kind of Radix Isatidis, all kinds of crowds all can learn to use.

The present invention is achieved by the following technical programs:

A kind of culture technique of Radix Isatidis, the culture technique of this Radix Isatidis may further comprise the steps:
