Mining, dredging and drying in spring and autumn are distributed in most parts of the country.
Danshen likes mild climate, plenty of sunshine, moist air and fertile soil.
During the growing period, there is insufficient light, low temperature, slow seedling growth and poor plant development.
Under the conditions of annual average temperature 17. 1℃ and average relative humidity of 77%, it grows well.
It is suitable for growing on sandy soil with fertile soil, has wide adaptability to soil pH, and can grow under neutral, slightly acidic and slightly alkaline conditions.
Salvia miltiorrhiza seeds are usually produced in early July, and can be sown after planting. Can be raised in the field, can also be planted under the seedlings, 5-6 kilograms of seeds per mu. In that year, the yield of salvia miltiorrhiza seedlings per mu could reach 200,000-300,000 plants.
2. Radix Isatidis
Isatis indigotica is a biennial herb with strong adaptability. It is cultivated in most parts of the country, mainly in Anhui, Gansu, Shanxi, Hebei, Shaanxi, Inner Mongolia, Jiangsu, Heilongjiang and other places.
Isatis indigotica likes warm environment, is cold-resistant and afraid of waterlogging, so it is suitable to choose sandy loam with good drainage and loose fertility, and should not be planted in low-lying land which is easy to accumulate water.
Banlangen is planted in spring and summer.
Summer sowing generally adopts the new species of the year, and seeds are produced in mid-June, with an average yield of 3 kg per mu 150-200 kg.
3. Achyranthes bidentata
Achyranthes bidentata is a perennial herb of Amaranthaceae, also known as Achyranthes bidentata (Sichuan) and Achyranthes bidentata (Huaiqingfu, Henan).

Achyranthes bidentata likes warm climate and is suitable for growing in dry, sunny and well-drained sandy loam. It requires deep soil layer, loose and fertile soil, which is conducive to root growth. Sticky orange soil and waterlogged saline-alkali soil are not suitable for planting.
Achyranthes bidentata was planted in mid-July, which led to early flowering and fruiting, lignified roots, and short growth period of Achyranthes bidentata, generally about 70 days, with 4 kilograms of seeds per mu.

Cultivated in northern and southern provinces of China, the soil yield in Northeast China and Inner Mongolia is relatively large, and the domestic species yield in East China and North China is relatively large.
Platycodon grandiflorum is best planted in summer.
But the planting area should not be too large, and it is better to plant in a small area. When planting, you must cover weeds to conserve moisture, and you can plant seedlings in 5-7 days.
