Red Sage Seed

Red Sage, Chinese medicine name. Salvia miltiorrhiza Bge is a plant in the labiaceae family. Dried roots and rhizomes. Spring and autumn harvest, remove sediment, dry. It is found in most parts of the country. It has the effect of activating blood circulation and removing blood stasis, relieving pain through menstruation, clearing the heart and eliminating irritability, cooling blood and eliminating carbuncle. It is used for chest arthralgia, abdominal and hypochondriac pain, mass accumulation, heat arthralgia pain, upset and sleepless, irregular menstruation, dysmenorrhea, sore sore.

Biological characteristics of salvia miltiorrhiza

Salviorrhiza salviorrhiza is a typical perennial herb with a height of 35-80 cm. The roots are slender and cylindrical, thick and fleshy. The appearance is brick red, the stem is upright and square, and there are 4 small nuts, 

showing an oval shape. The flowering period of salvia miltiorrhiza is from May to July every year, and the fruit period is from June to August. Salviorrhiza prefers a warm, moist and sunny planting environment, and is more 

suitable for planting on sandy loam soil with thick soil layer, good drainage, medium fertility and good ventilation.

The main breeding mode of salvia miltiorrhiza

1. Root propagation

In the south of our country, we generally choose the method of split root planting, the seeds are left in the ground with salvia miltiorrhiza, and when planting, we should dig with the planting. Under normal circumstances, 

the side roots of salviorrhiza can be selected as seeds with a diameter of 0.3 cm and strong, bright red roots, which can be planted in February to March every year, or selected and planted in October when harvest. The row 

spacing is 45 cm, the plant spacing is 30 cm, the hole depth is maintained as 4 cm, the pig manure and pig urine are applied as the base fertilizer, and 1500-2000 kg of farm fertilizer is applied to each mu of land. When planting, 

the length of the root is 4-6 cm, and it is well protected from freezing and covered with straw to keep warm.

2. Cutting propagation

This planting method is generally used in North China, Jiangsu and Zhejiang regions. In North China, it is generally planted in June to July every year, and in Jiangsu and Zhejiang areas, it is planted in April to May. Take the stems 

and leaves above Salvia miltiorrhiza and cut them into 5-10 cm segments in time, cut off all the lower branches and leaves, and cut off half of the upper branches and leaves, and insert them with the cutting. And according to 20 cm 

row spacing, 10 cm plant spacing for planting, cutting buried in the soil 6-8 cm. After the cutting is completed, it is necessary to water it immediately and shade it in time according to weather conditions. Wait until the salvia miltiorrhiza 

plants grow to 3 cm, transplant into the field for planting.

3. Seed propagation

Also known as seedling breeding, in the northern regions, generally in March for seeding seedlings, covered with 1-1.5 cm thick soil above the seeds, watering immediately after sowing, and covered with plastic film to ensure 

that the soil is moist enough, generally take 15 days to emerge. In Jiangsu and Zhejiang regions, the seeds are mature in June, sown and covered with soil immediately after harvesting, watered and covered with grass to keep 

the soil moist enough, and planted in the field in October.

4. Live breeding

In North China, the seed is generally sown in April, and the method of cave sowing or drill sowing is chosen. If the seeds in each hole are controlled at 5-10 seeds, each mu of land is sown in drill with 0.5-0.6 kg of seeds, the 

trench is 1 cm deep, and the soil above the seeds is 0.6-1.5 cm.

Artificial planting technology of salvia miltiorrhiza

1. Site selection

When planting salviorrhiza, it is generally necessary to choose sunny, deep soil and good drainage area as planting area, and try to choose sandy soil. If the soil viscosity is too large, it will affect the drainage, and then affect 

the respiration of the root system, resulting in the emergence of root rot. After the harvest of the previous autumn crop, the field needs to be deeply ploughed, before the next spring planting, for a width of 1.2 meters, 20 cm 

high field bed, border trench width of 25 cm, in the preparation of the land, apply 1500-2000 kg of fertilizer as the base fertilizer. If you want to achieve high yield, you should choose 1-2 years of unpolluted areas as planting 

areas, laying a high-yield foundation for the growth of medicinal herbs Danshen.

2. ridge film

After tillage, the soil should reach the upper deficiency and lower solid, flat without clogs, and you can begin to lay the bedding. The ridge can be roughly divided into two kinds of high ridge and ridge, high ridge is faster and 

less time-consuming, but the yield is not as good as ridge, ridge planting salvitis is generally about 10% higher than the ridge.

(1) Make ridges

The ridge height is set to 20 cm, the ridge top width is 40 cm, and 2 rows of Danshen can be planted in each ridge. Ridge planting Salvia miltiorrhiza can increase ground temperature, facilitate drainage in rainy season and 

prevent root rot, which is one of the important ways to increase yield of Salvia Miltiorrhiza. The ridges should be slightly higher in the middle, with a gentle slope shape on both sides.

(2) mulch

The film is a high pressure low density ethylene film, its thickness needs to be 0.13-0.18 mm, the amplitude of 90-120 cm. Generally, the amount of mu is 7-10 kg. The mulching film of salvia miltiorrhiza is good for preserving 

soil moisture and increasing temperature. The mulching film should be covered close to the ridge surface and transplanted according to the row spacing.

3. Transplanting

The transplanting of salvia miltiorrhiza can be divided into autumn planting and spring planting. Autumn planting of salviorrhiza is generally carried out in mid-October to early November every year, and it must be planted early 

and take root before the frost falls, and the survival rate is higher. Generally, the root diameter of 0.3 cm, the number of leaves is greater than 10 pieces, and the seedling height is more than 10 cm, cut the taproot 2 cm long and 

soak the root with 50% carbendazim solution for 10-15 minutes to promote root division and sterilization. Then plant according to the row spacing of 20 cm ×25 cm, dig planting holes about 9 cm deep, plant 2-3 plants in each 

hole, water in time to stabilize the roots, and cover the soil in time to the flat hole after watering, and compact the soil around the mulch film at the edge of the hole with fine soil.

4. Field management

(1) Topdressing

In order to promote the expansion of plants and root strips, salvia miltiorrhiza should be fertilized three times during the growth period. Topdressing can be combined with ploughing and weeding. The first topdressing should be 

applied at the time of salvia miltiorrhiza greening. 1250-1500 kg of rotting human manure should be used for each mu of land, and then irrigated with water; The second topdressing must be applied from mid-April to late May 

each year. Plots without salvia miltiorrhiza seeds can be cut after inflorescence, each mu of the application of decomposed human manure 1000 kg, cake fertilizer 50 kg; The third topdressing must be carried out in June-July every 

year, after cutting the old rod, applying long root fertilizer, suitable for heavy application, each mu of thick feces applied 500 kg, and with the application of superphosphate 20 kg, potassium chloride 10 kg. Both the second and third 

application were ditch or hole application, and the soil was covered without fertilizer in time after fertilization.

(2) ploughing and weeding

Generally, three weeding sessions are carried out during the whole plant stage of Salvia miltiorrhiza. The first time is when the seedling height is 6 cm, the second time is in June, and the third time is in July-August. After that, no more 

tillage and weeding, and no herbicides should be used.

(3) Drainage and irrigation

After transplanting, we must keep the soil moist enough to ensure the survival of the plants. Generally do not water after survival, drought in time irrigation or watering. In the rainy season, drainage should be timely to prevent root rot, 

and watering should be done after topdressing.

(4) Remove flower moss

Salviorrhiza blooms one after another from late April to May each year. In order to ensure that nutrients are concentrated in the root growth, in addition to remaining seeds, the flower moss should be removed, and the time should be sooner 

rather than later.
