Planting and Management of Salvia miltiorrhiza

The methods of root propagation, cutting propagation and seed propagation can be used to plant Salvia miltiorrhiza. Among them, split-root propagation is mostly used in Sichuan, cutting propagation is mostly used in North China, Jiangsu and Zhejiang, and seed propagation is available in most areas. In general, cultivated Salvia miltiorrhiza needs to do a good job in the management of weeding, water and fertilizer, bud picking and pest control.

The following is a detailed introduction of the planting method of Salvia miltiorrhiza:

1. Split root propagation

Split root propagation is mostly used in Sichuan producing areas. Salvia miltiorrhiza used for planting is generally left in the ground and planted with digging. The annual lateral roots, which are about 0.3 cm in diameter, stout and red in color and free from diseases and insect pests, are selected to be planted from February to March. It can also be planted at the time of harvest in November. According to the row spacing of 30-45 cm, plant spacing of 25-30 cm, hole depth of 3-4 cm. When planting, fold the selected root strips into 4-6 cm long root segments, fold while planting, root strips upward, 1-2 segments per hole. Immediately after planting, it is covered with about 1.5 cm of fine soil.

two。 Cuttage propagation

Cutting propagation is mostly used in North China, Jiangsu and Zhejiang. In general, the aboveground stems of Salvia miltiorrhiza were taken from June to July in North China and from April to May in Jiang and Zhejiang, and cut into small segments of 10-15 cm. The lower leaves were cut off and the upper leaves were cut off.

3. Seed planting

(1) Seedling transplanting: strip sowing was carried out in Beijing in March, covering 0.3 cm of soil, watering after sowing, covering with plastic film, keeping the soil moist, and emergence in about 15 days; in Jiangsu and Zhejiang areas, when the seeds were mature in June, they were sown immediately after harvest, covered with soil to cover the seeds, covered with grass and moisturized after sowing, and transplanted to the field in October.

(2) Direct broadcast: sowing, strip sowing or hole sowing in North China in mid-April. According to the same root-splitting method, 5-10 seeds were sown in each hole, the depth of strip sowing furrow was about 1 cm, the soil cover was 0.6-1 cm, and the sowing amount per mu was about 0.5 kg.

At present, the price of Salvia miltiorrhiza in most parts of the country is about 12 yuan / kg, and the inventory is not much, so the market situation is still very good. However, the majority of pharmaceutical farmers should always pay attention to the changes in the market, timely shipment, in order to obtain the maximum benefit.
