Salvia miltiorrhiza, ginseng, red ginseng, red salvia, red root and so on. Taking root medicine, is a commonly used Chinese herbal medicine. There are blood circulation to silt, swelling and pain relief, nourishing and sedative function. Sichuan, Hebei, Henan and Shandong provinces are all cultivated.
First, selection and site preparation
The cultivation of sandy soil with sunny, deep soil, and well-drained water is preferred. The soil is too viscous, aeration and poor drainage, often causing rot. Deep plowing after the previous autumn harvest. Before planting in the spring of the following year, the beak is 1.2 meters wide and 20 centimeters high. The sulcus is about 25 cm wide. During the site preparation, 1500-2000 kg of compost or manure per acre was used as base fertilizer.
Second, the breeding method
1. Seed Reproduction Plants left in the field are harvested in batches after the seeds mature in June and then dried in the sun. The seed germination rate of Salvia miltiorrhiza is about 70%, and the germination rate of Chen seeds is very low and cannot be adopted. After the seeds are harvested, they must be sown in time, and in some places, sown in the fall of September. Southern areas, such as Zhejiang, are sown after the June seeds are harvested. Drilled or sowed, covered with thin soil after sowing, back cover grass or plastic film. After the emergence, the cover was gradually removed. The seedlings were transplanted at a height of 6-10 cm and the spacing was 3020 cm.
2, the roots of the majority of provinces and regions to adopt this method. When digging, the digging will not be digging, and the digging and planting will be carried out in the next 2-3 months of the following year. The seedlings for seeding should be selected to be 0.7-1 cm in diameter. The robust rootless, disease-free and red-colored annual roots are preferred. . The selected roots were chopped into a length of about 5 cm. Plants were planted at a spacing of 3025 cm and covered with about 3 cm of soil. Use 50 kg per mu.
Third, field management
1. Weeding and weeding are usually conducted three times in cultivating and weeding; the first time when returning to green or when the height of seedlings is about 6 cm; the second time is in June; and the third time in July and August. After the ridge closure, it is inconvenient to carry out cultivating and weeding again. Herbs are planted with herbicides disabled.
2. Top dressing is mainly based on base fertilizer, such as insufficient base fertilizer, which can be combined with cultivating and weeding topdressing.
3, pay attention to drainage rain flood season. The stagnant water affects the growth of Salvia miltiorrhiza, reduces yield, quality, and even kills roots.
4. In addition to the plants that are ready to harvest the seeds during the flowering and flowering period, the inflorescences must be removed in order to facilitate root growth.
