Planting techniques of Salvia miltiorrhiza cultivation and management methods of Salvia miltiorrhiza

Sowing in North China in the middle of April, strip sowing or hole sowing can be selected, hole sowing row spacing is 30-45 cm, plant spacing is 25-30 cm, each hole sows 5-10 seeds, strip sowing groove depth is about 1 cm, soil cover is 0.6-1 cm, sowing amount per mu is about 0.5 kg, in case of dry climate, it is necessary to water thoroughly before sowing before sowing, generally seedling emergence half a month after sowing, seedling determination can be carried out when the seedling height is 6 cm. Ploughing and weeding 3-4 times a year, and topdressing in time for the second and third years.

When it comes to Salvia miltiorrhiza, many people should know better, because Salvia miltiorrhiza is a famous traditional Chinese medicine in China, and it is not common in daily life. It not only has very high medicinal value, but also has high health care efficacy. Today, the editor will introduce to you the planting skills of Salvia miltiorrhiza.

Planting technique 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 row spacing of 30-45 cm, plant spacing of 25-30 cm, hole depth of 3-4 cm, pig manure and urine, 1500-2000 kg per mu. 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, the soil is covered with a thickness of about 1.5 cm. According to the production practice, using the head and tail of the root to plant seedlings early and late in the middle, therefore, it is necessary to plant separately to facilitate field management. The Lignified mother root is not suitable for seed planting because of its poor germination ability and low yield. Separate root planting should pay attention to anti-freezing, can cover straw to keep warm.

2. Cutting 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. On the finished border, open a shallow trench according to the row spacing of 20 cm and the plant spacing of 10 cm, then insert the cuttings obliquely along the trenches, and bury the cuttings in 6 cm of soil. Watering and shading should be carried out after cutting. When the regenerated root grows to about 3 cm, it can be transplanted in the field. Others will split off the root of the plant directly planted, pay attention to watering, can also survive.

3, seed planting: ① seedling transplant: in Beijing, strip sowing is carried out in March, covering soil 0.3cm, watering after sowing, covering with plastic film, keeping the soil moist, about 15 days emergence; in Jiangsu and Zhejiang areas, when the seeds mature in June, sowing immediately after harvest, covering the soil to cover the seeds, sowing grass to protect moisture, transplanting in October in the field. ② live 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. In case of drought. Water thoroughly before sowing. The seedlings emerged half a month after sowing. The seedlings were fixed when the height of the seedlings was 6 cm.

Cultivation and management methods of Salvia miltiorrhiza

It is better to replenish seedlings sooner rather than later, so that they can catch up with the surviving seedlings as soon as possible. To achieve consistent growth. Intertillage weeding needs to be carried out 3 or 4 times a year. Weeding methods can be manual weeding or pulling, or mechanical weeding, but not chemical weeding. The florescence of Salvia miltiorrhiza is from May to June. The tidbits should be removed as soon as possible without collecting the seeds. Salvia miltiorrhiza is a kind of plant which likes potassium and organic fertilizer. The cake fertilizer or high-quality mature farm manure was applied once after spring germination in the second and third year (late April). In addition, extra-root topdressing was carried out in early March and July every year, and foliar nutrient solution and humic acid were sprayed. The application rate is 150g per mu. Foliar spraying of topdressing outside roots should be carried out before 10:00 and after 4 p.m., foliar spraying should be uniform, both front and back of leaves should be sprayed.

Growth habit

Salvia miltiorrhiza prefers a warm, humid and sunny environment. It grows well under the conditions of an annual average temperature of 17.15 ℃ and an average relative humidity of 77%. When the temperature is-5 ℃, the stems and leaves suffer frost damage; the underground roots are cold-tolerant and can survive the winter in the open air, and the seedlings encounter high temperature and drought weather, growth stagnation or death. Salvia miltiorrhiza is a deep-rooted plant, which grows well in sandy loam with deep and fertile soil, good drainage and medium fertility. The soil is too fertile and ginseng roots do not grow sturdy; rotting roots can be caused in low-lying land with waterlogging and poor drainage. It is better that the pH of soil is near neutral. Salvia miltiorrhiza grows poorly in sandy or clayey soil.

After the salvia miltiorrhiza plant turned green, the stem and leaf grew faster from March to April, and the plant died after the fruit matured. After falling the seedling, the plant grew new buds and leaves again, and entered the second growth. The mother plant generally had 3-5 ramets, and began to branch from the first ten days of April. Flowering stems are less in autumn, and only 1/3 in spring, long sunshine time from July to August is beneficial to root growth.

Harvest and processing

Radix Salviae Miltiorrhizae can be collected in the next year. The harvest time is the shoot withered in the middle of December or dug before germination in the following spring. First remove the aboveground stems and leaves, and open a deep trench at one end of the border to expose the ginseng roots. Dig out the complete root strip forward along the bed to prevent it from breaking. After digging up, cut off the stump. If you need a piece of Salvia miltiorrhiza, the root strips above 0.8cm in diameter can be cut off at the mother root, arranged in order, exposed to the sun, and turned from time to time. When it is 70 or 80% dry, it is tied into a small handful, then exposed to dry, and boxed into "Salvia miltiorrhiza". If you don't distinguish the thickness. Dried and packed in gunny bags is called Salvia miltiorrhiza.

Through the above content, I believe you also have a certain understanding of the planting method of Salvia miltiorrhiza. In our life, many people like to use Salvia miltiorrhiza to treat and prevent some diseases, and even eat Salvia miltiorrhiza to maintain health and health care. Salvia miltiorrhiza is very popular in the market, so the prospect of planting Salvia miltiorrhiza is still very broad.
