Planting Prospect of Salvia miltiorrhiza

Salvia miltiorrhiza, also known as Radix Salviae Miltiorrhizae, relieving pain, cooling blood and eliminating carbuncle, clearing the heart, nourishing blood and calming the mind, is a commonly used bulk of traditional Chinese medicine. It is suitable for planting in hilly areas with drought and little rain, water shortage and sandy loam. The yield is stable and the benefit is high. Let's take a look at the planting prospects and benefits of Salvia miltiorrhiza.

Planting Prospect of Salvia miltiorrhiza

Salvia miltiorrhiza has a wide range of uses and high curative effect, the national demand is growing rapidly, and in some years supply exceeds demand. In the early 1960s, the national annual demand was less than 1 million kg, which increased to 6.52 million kg in 1978, and sales increased by more than 5.5 times in the past 18 years. The reason for the rapid increase in demand, in addition to demographic factors, is that the development of science and technology has made more and more uses of Salvia miltiorrhiza.

Scientific research has found that Salvia miltiorrhiza not only has the function of promoting blood circulation and removing blood stasis, but also has a new curative effect on cardio-cerebrovascular disease, liver disease, vasculitis, neurasthenia and other diseases. There are nearly 100 kinds of proprietary Chinese medicines such as Danshen ointment, Danshen tablets, compound Danshen Tincture, Guanxin tablets, Danshen Gegen Liuhu tablets, Danshen pills, Salvia miltiorrhiza injection, Shuxin granules, Guanxin granules, compound Glycyrrhiza Danshen tablets, etc., and more than 10 dosage forms are produced, such as honey pills, water pills, tablets, sprays, granules, syrup, injections and so on.

Especially in recent years, with the change of people's dietary structure and the emergence of social aging, the incidence of cardiovascular disease is on the rise. Salvia miltiorrhiza plays an irreplaceable role in clinical treatment and prevention, so that the value of Salvia miltiorrhiza doubles and the dosage doubles. Demand-stimulated production also stimulates mining, which has caused serious damage to wild resources in successive years, with some places on the verge of extinction, resulting in a continuous reduction in output and a great decline in quality. The promotion of the new technology of artificial cultivation is not fast, the per unit yield is not high, and the total yield is not stable. in some places, due to serious diseases and insect pests, a large number of pesticides and fertilizers are applied unscientifically in some places, which greatly affects the quality of artificially cultivated Salvia miltiorrhiza.

Therefore, the market for medium-and high-grade products, especially export products, has been tight, and the prices have risen steadily. From 1998 to 1999, the market prices of the 75 largest medicinal materials in the country have been maintained at 11,18 yuan / kg. Thus it can be seen that the benefit of producing green medium-and high-grade Salvia miltiorrhiza is good, and the market potential is still quite great by selecting pollution-free and pollution-free plots in suitable areas, selecting excellent varieties and adopting standardized cultivation techniques of Salvia miltiorrhiza.

Investment cost of Salvia miltiorrhiza (excluding land)

1. Seedlings: 8000 Salvia miltiorrhiza seedlings are planted per 667 / mu, the price of high-quality seedlings on the market is 0.06 yuan per mu, and the investment per mu is 480 yuan.

2. Cultivated land: generally deep ploughing once, rotary ploughing once, the cost per mu is about 80 yuan.

3. Fertilizer: use 50 kg compound fertilizer as base fertilizer per mu, about 150 yuan. Plus topdressing, about 50 yuan. The total is 200 yuan (excluding farm manure).

4. Pesticides: in general years, Salvia miltiorrhiza disease is less, in the growing period, the disease occurs twice, mainly to prevent, the cost is less.

5. Other: the labor cost of planting, receiving and drying, due to different factors such as cultivation method, planting time, environmental conditions, etc., if there is no budgeted investment, it will be calculated at 800 yuan.

Planting benefit of Salvia miltiorrhiza

Salvia miltiorrhiza is planted in late autumn or early spring, the growing period is one year, and the harvest is in the autumn of that year. In general years, in the absence of major natural disasters, the average yield of dry goods is 50g / tree, and 8000 trees are cultivated per mu. According to the survival rate of 90%, dry salvia miltiorrhiza can be harvested per mu.

If according to the unified goods (regardless of size) market price 14-18 yuan / kg, the income per mu is 6000-6500 yuan, excluding the undergraduate profit of 3300-4800 yuan.
