Scientific cultivation methods of Salvia miltiorrhiza

Salvia miltiorrhiza is a kind of ginseng plant, which is also called Radix Salviae Miltiorrhizae because it looks red. It is widely distributed in various areas of Sichuan, especially in Zhongjiang. Salvia miltiorrhiza is usually planted in sweet potato field or corn field. Then it is planted after soil preparation. So how to cultivate Salvia miltiorrhiza, a traditional Chinese medicine plant? Now let's introduce the cultivation methods to you.

I. planting methods

1. Root-splitting propagation

Most of the producing areas in Sichuan use the method of root-splitting propagation, and the salvia miltiorrhiza to be planted is left in the ground. When we plant, we can dig and plant it at any time. When we choose, we should choose those with no diseases and insect pests, and the color is sturdy and red. The planting time can be planted from February to March, or you can choose to plant in November. After determining the row spacing and plant spacing, you can start planting. After planting can be carried out pig manure urine, generally 1500-2000 kg per mu of fertilizer, the use of root planting should pay attention to the landlord warm measures.

2. Cuttage propagation

Cutting propagation is mainly used in North China, selecting the aboveground stem of Salvia miltiorrhiza, taking out the aboveground stem, cutting off the leaves of the lower part with special scissors, cutting the upper part in half, cutting after cutting, according to a certain line spacing, plant spacing, watering should be carried out after cutting, and after it grows to a certain length, it can be transplanted to the ground.

3. Seed propagation

The method of seed reproduction is relatively simple. First, the seeds are soaked, disinfected and sterilized, then strip sown, watered after sowing, then covered with plastic film, covered with soil, and then covered with grass for moisturizing. Direct seeding is the best when sowing in mid-April in North China. The follow-up work such as emergence and determination of seedlings can be carried out after half a month.

II. Field management

1. Ploughing and weeding

Because the soil cover will be relatively thick, so the emergence of seedlings will be relatively slow, so we have to choose the time when the seedlings begin to be unearthed and check the growth of the seedlings. If there is soil consolidation, it will affect the emergence of seedlings, so it will affect the emergence of seedlings. The covering soil of the hole should be removed in time to promote the speed of seedling emergence.

2. Fertilization

In combination with ploughing and weeding during the growth period, generally topdressing more than 2 times according to the situation, more than 1000 kg of fermented farm manure is used per mu, and more can be applied when the rainfall is not ideal. Fertilizer can be used, such as cake fertilizer, which does not limit the kind. Just make sure it's enough.

3. Drainage and irrigation

Observe the drainage situation at ordinary times, avoid waterlogging, keep the soil moist in the seedling stage and seedling stage, and irrigate or water it in time.

III. Pest control

1. Root rot

Root rot is a season that often occurs in high temperature and rainy season. after suffering from root rot, the roots of the injured plants will turn black, and the top of Salvia miltiorrhiza will turn black. for the plant areas with this disease, we should taboo continuous cropping to avoid the infection of the disease, and then use carbendazim solution to irrigate.

2. Aphids

Aphids are mainly sanitary by sucking plant sap, and most of them occur in summer, so we can use chlorpromazine for spraying treatment, spraying once a week and spraying several times in a row can be controlled.

These are the scientific cultivation methods of Salvia miltiorrhiza. The most common pests of Salvia miltiorrhiza are aphids and root rot, and other pests include Spodoptera litura, Helicoverpa armigera and grubs, but these are very rare, and the common ones are those two, so they are not introduced in detail.
