Planting prospect of Corydalis yanhusuo

Rhizoma Corydalis, also known as Yuanhu, Xuanhu, etc., warm in nature, hard in taste, entering the heart, spleen, liver and lungs, is the effect of promoting blood circulation and removing blood stasis, promoting qi and relieving pain, is one of the commonly used varieties of traditional Chinese medicine, with an annual consumption of about 5000 tons, with high planting prospects and planting benefits. Let's take a look!

Planting prospect of Corydalis yanhusuo

Rhizoma Corydalis is a commonly used variety of traditional Chinese medicine, and its extract contains more than 20 kinds of alkaloids, which are mainly effective in promoting blood circulation and removing blood stasis, regulating qi and relieving pain. because it relieves pain without addiction, it can also be used in the late stage of cancer, which is similar to the function of "Panax notoginseng". Due to the high price of Panax notoginseng, as a substitute, the market demand of Rhizoma Corydalis is increasing, as China's traditional Chinese medicine products gradually begin to go abroad. The demand of Rhizoma Corydalis abroad is also increasing, with a total demand of more than 20,000 tons, nearly twice the production capacity.

In recent years, the production and sales of Rhizoma Corydalis in China are booming, and the price is rising steadily. With the more and more extensive application of Rhizoma Corydalis in the field of medicine, the demand is increasing, and the market prospect is very broad. Rhizoma Corydalis and Atractylodes macrocephala, Paeonia lactiflora, Fritillaria and so on are called "Zhejiang eight flavors".

After the price trough occurred in 2002, the planting area of Panan, Dongyang and Jinyun in Zhejiang and Xuanzhou in Anhui gradually shrank, and the production of Corydalis yanhusuo was continuously reduced due to the impact of industrial development and other cash crops. Shaanxi Chenggu has outstanding economic benefits due to suitable ecological environment and relatively low labor force, and the planting area has expanded year by year. At present, China has basically formed two major production areas with Zhejiang Pan'an and Shaanxi Chenggu as the center. In 2012, the annual cultivation area of Corydalis was 104600 mu, with an annual output of 12600 tons.

Planting benefit of Rhizoma Corydalis

1. Panan producing area: the economy of this producing area is more developed, the per capita land area is less, and the land cost is higher. Few people planted Corydalis yanhusuo, and most of them were planted by drug farmers in their own land. The cost is also mainly occurred in chemical fertilizer, please a small number of people to dig, generally the cost per mu of land is about 1000 yuan. The yield per mu is not different from that in Hanzhong, and most of them are processed by drug farmers into dry goods for sale, and the income is much higher than that in Hanzhong.

2. Hanzhong producing area

① mu planting cost: most of the drug farmers in Hanzhong area keep their own seeds, and few people buy Corydalis yanhusuo planting. The planting cost mainly occurs in the aspects of planting, mining, chemical fertilizer, watering, field management, land concession and so on. The total investment per mu is about 2500 yuan (seed cost: the producing area is generally planted by machine, and the cost per mu is about 90-100 yuan. Mining costs: Yanhusuo mining can not use machinery, mostly manual excavation, a mu of land needs about 20 man-hours, the cost is about 1500-1600 yuan. The total cost of chemical fertilizer, watering, field management and land concession is about 900 yuan. )

② yield per mu: yanhusuo yield per mu is generally 400kg-500kg.

③ mu income: the purchase price of fresh Corydalis is 9-9.6 yuan this year, the total income per mu is about 4200 yuan, and the net income per mu after deducting the cost is about 1700 yuan.

Present situation of processing of Rhizoma Corydalis

1. Zhejiang producing area: Panan producing area of Zhejiang is the authentic producing area of Rhizoma Corydalis, which has a long history of planting and mature planting and processing technology, and the purchase price of Corydalis is higher than that of Hanzhong. In addition, most of the drug farmers in this producing area process fresh Rhizoma Corydalis into dry Corydalis, and their income is much higher than that in Hanzhong. The net income of ordinary pharmaceutical farmers in Zhejiang producing areas can reach more than 3,000 to 4,000 yuan per mu.

2. Hanzhong producing area: because the processing and drying of Corydalis is troublesome, it will be sunny all day, pile it up at night, spread it out again the next day, and turn it over for two hours. When the weather is good, it can be dried in seven days, but the weather is bad for more than ten days. Therefore, pharmaceutical farmers seldom process fresh Corydalis into dry Corydalis for sale, and mostly sell fresh Corydalis to local processing households for processing. The total amount of Rhizoma Corydalis processed by processing households is about 70-80% of the total output of Rhizoma Corydalis. The drying rate of Rhizoma Corydalis is generally 3.5-3.7. In other words, when processing one kilogram of Rhizoma Corydalis, the cost of processing fresh Corydalis is 32-34 yuan. Plus some other costs (such as labor costs, etc.), the cost of a kilogram of dried Corydalis is about 37-38 yuan. At present, the purchase price of yanhusuo is 40-41 yuan, and processors can only earn 2-3 yuan per kilogram. Although it is profitable for processing households, if the supply of goods is not good and the market is weak, the financial pressure will also be great.
