Scientific planting techniques of Radix Salviae Miltiorrhizae
I. Overview
Alias salvia miltiorrhiza, blood ginseng root. Take medicine with root, activate blood circulation and regulate menstruation, insomnia and palpitation. Modern medicine has a significant effect in the treatment of coronary heart disease and angina pectoris.
II. Biological characteristics
Like a warm, moist, sunny environment, the stems and leaves are frozen at minus five degrees Celsius, and the underground roots are cold-resistant and can survive the winter. High temperature at seedling stage, drought seedling stagnation or even death, avoid waterlogging, over-sand, over-sticky low-lying soil is not suitable for planting.
III. Cultivation techniques
1. Land selection and preparation. The main results are as follows: (1) Seedling land, land with high topography and loose soil layer. Make a high bed and apply rotten barnyard manure or compost as base fertilizer. (2) the planting land should be planted on the land with deep soil layer, loose and fertile soil, high topography and good drainage. (3) in mountainous areas, choose sunny low slopes.
2. Raising seedlings. The border was made in late March with a width of 1.3 meters, a horizontal trench sowing according to the row spacing of 33 cm, a ditch depth of 1 cm, seeds mixed with fine sand into the ditch, covering the soil with no seeds, covering with plastic film after sowing, punching and releasing seedlings with plastic film after emergence, seedlings with a height of 6 cm and transplanting in late May.
3. Transplant. Spring planting in mid-May, autumn planting in late October, early transplanting, early rooting, early turning green the following year. The surface of the border is dug according to the row spacing of 33 × 23 cm, and the depth of the hole depends on the length of the root, and the base fertilizer is applied at the bottom of each hole to plant 1-2 seedlings (that is, seedlings).
4. Seed propagation and seedling co-breeding.
IV. Field management
1. Ploughing, weeding and topdressing three times a year.
2. Except that the buds concentrate the root nutrients and leave the seed land, all the buds should be cut off.
3. Drainage and irrigation timely drainage in rainy season and timely ditch irrigation or watering in dry days.
Prevention and control of diseases and insect pests
The main results are as follows: 1. Dark brown spot appeared in the disease part of leaf spot, and when the leaf was serious, the leaf withered and died, so crop rotation was carried out. Spray 0.3% potassium dihydrogen phosphate or carbendazim, thiophanate, and zinc benzoate.
2. the branch root or whisker root of root rot turned brown and rotted, resulting in the death of the whole plant. It was irrigated with 50% carbendazim 800-1000 times solution and 50% methyl topiramate 1000 times solution.
3. Root-knot nematode disease due to the parasitism of root-knot nematodes, many nodules are produced in the roots, so that the plant develops slowly, and finally the whole plant dies, and the control rotates with cereal crops; 3% isosphos-methyl is applied.
4. The larvae of Spodoptera litura fed on the leaves of Salvia miltiorrhiza, and in serious cases, the leaves were eaten up to prevent and destroy the residual branches and leaves after harvest; spraying 10% permethrin 2000-3000 times, 40% omethoate 1000 times, and 90% trichlorfon 1000 times.
VI. Harvesting and processing
In the year of asexual reproduction, it can be collected before germination in November of the same year or in the spring of the second year, and can be dug from October to November of the second year to the early spring of the third year. After digging, it can be exposed to the sun in the field, removed soil and transported back, and water washing is avoided. When drying to the fifth layer, tie it into small bundles, pile 2-3 angels to sweat, then spread out to dry, remove the hair and trim the rash, cut off the fine tail to become a commodity.

Field management measures of Salvia miltiorrhiza
Speaking of Salvia miltiorrhiza, I think we are very familiar with it. Salvia miltiorrhiza is a common and commonly used traditional Chinese medicine. Many people should know the efficacy of Salvia miltiorrhiza. It is precisely because the market demand of Salvia miltiorrhiza is relatively large, so the planting scope of Salvia miltiorrhiza is gradually increasing.
