Salvia miltiorrhiza breeding method Danshen planting prospects and benefits, Danshen, also known as red ginseng, purple salvia, red roots, with blood circulation, phlegm and stasis, pain relief, cooling blood to eliminate phlegm, clear heart and trouble, nourishing blood and soothe the effect, is commonly used Large Chinese herbal medicines are suitable for planting in hilly areas with drought and little rain, lack of water resources and sandy loam. The yield is stable and the benefits are high. Let's take a look at the planting prospects and planting benefits of Salvia miltiorrhiza!
The prospect of planting Danshen is widely used and has high curative effect. The demand in the country is growing rapidly, and some years are in short supply. In the early 1960s, the national annual demand was less than 1 million kilograms, and by 1978 it had increased to 6.52 million kilograms. In 18 years, sales volume increased by more than 5.5 times. The reason for the rapid increase in demand, in addition to population factors, is mainly the development of science and technology to make the use of Danshen more and more.
Scientific research has found that salvia miltiorrhiza not only has the function of promoting blood circulation and removing blood stasis, but also has new curative effects on various diseases such as cardiovascular and cerebrovascular diseases, liver diseases, vasculitis and neuropathic debilitation. Nearly one hundred kinds of Chinese patent medicines such as Danshen cream, Danshen tablets, compound Danshen sputum, Guanxin tablets, Danshen Gegen Liuhu tablets, Danshen pills, Danshen injection, Shuxin granules, Guanxin granules and compound licorice Danshen tablets The dosage forms produced include more than 10 kinds of honey pills, water pills, tablets, sprinkles, granules, syrups and injections.
Especially in recent years, with the changes in 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 other drugs during clinical treatment and prevention. The value of Salvia is doubled and the dosage is doubled.
Demand stimulation stimulates mining, and large-scale mining has caused serious damage to wild resources. Some places are on the verge of extinction, production continues to decrease, and quality is greatly reduced. The new techniques of artificial cultivation are not popular, the yield is not high, and the total output is unstable. In some places, due to serious diseases and insect pests, a large number of unreasonable application of pesticides and fertilizers have been carried out in successive years, which has greatly affected the quality of artificial cultivation of Salvia miltiorrhiza.
Therefore, the market's high-end products, especially export products, have been tight, and prices have risen steadily. From 1998 to 1999, the price of the 75 major medicinal materials in the country has been maintained at 11-18 yuan/kg. It can be seen that the current selection of non-polluting and pollution-free plots in suitable areas, the selection of excellent varieties, and the adoption of standardized Danshen cultivation techniques, the benefits of producing green high-grade Danshen are good, and the market potential is still quite large.
Danshen's investment cost (excluding land)
- Seedlings: 667 trees per square meter of gansu seedlings planted 8000 trees, the market price of high-quality seedlings 0.06 yuan / tree, each mu needs to invest 480 yuan.
- Cultivated land: Generally, the land is deeply cultivated once and rotated once, and the cost per mu is about 80 yuan.
- Fertilizer: 50 kg of compound fertilizer per mu as base fertilizer, about 150 yuan. Plus topdressing, about 50 yuan calculation. A total of 200 yuan (farm is not counted).
- Pesticides: In the general year, Danshen has fewer diseases. In the growing season, the disease occurs twice, mainly for prevention, and the cost is less.
- Others: labor costs for planting, receiving, and drying. Due to different factors such as cultivation methods, planting time, and environmental conditions, there is no budget-oriented investment, which is calculated at 800 yuan.
The planting benefit of Salvia miltiorrhiza is planted in late autumn or early spring, and it is harvested in the autumn of the year. In the general year, in the absence of natural disasters, the average yield of dry goods is 50 g/tree, and 8,000 trees per mu are cultivated. According to the survival rate of 90%, 360 kg of dried salvia can be harvested per mu. If the market price is 14-18 yuan/kg according to the unified goods (excluding size), the income per mu is 6000-6500 yuan, and the cost of the section is 3300-4800 yuan.
Method of breeding Salvia miltiorrhiza
Danshen is born in the grass, ditch, roadside or forest edge of Xiangyang hillside. It is distributed in most parts of the country. The breeding methods are divided into seeds, roots, reeds or cuttings. The yield of reproductive material is the highest. Followed by roots.
The seeds are propagated in spring, in the middle and late March, and they are sown on the whole surface of the glutinous rice. After sowing, the mulch is covered and moisturized. It can be emerged in about 15 days. Seedling height 5-6 cm time seedlings. When the seedling height is about 10 cm, it will be planted.
The roots are propagated in the south for 2-3 months and the north for 3-4 months. On the whole surface, the row spacing is 33-35 cm, the plant spacing is 23-25 ​​cm, and the base is applied to the base. The roots of the stored roots are cut into 5-7 cm segments, with the heads facing up, each hole. Straight into a section, covered with soil about 3 cm after planting, covering soil should not be too thick, otherwise it is difficult to emerge, and can not be planted, otherwise it will not germinate.
When the head of the reed head is harvested and digested, the plants with strong growth and no pests and diseases are selected, and the roots are used for medicinal purposes. The fine roots with a diameter of 0.6 cm are cut off together with the reeds on the roots, and the burrowing and rooting propagation methods are used. the same.
Cutting and cutting to grow strong stems, cut into small pieces of about 20 cm, with the cutting and inserting, deep into the 1/2 or 1/3 of the cuttings, keep the surface moist after the insertion, appropriate shading for about half a month That is, it can take root.
