Planting and growth conditions of Salvia miltiorrhiza

Salvia miltiorrhiza is a traditional Chinese medicine plant of Labiatae, mainly taking its rhizome as medicinal materials, which is distributed in many areas of the country and can treat a variety of diseases. Wild resources are scarce, so the scale of artificial cultivation is very large. There are many cultivated areas and quantities. So how to grow Salvia miltiorrhiza, under what environment, what kind of growth conditions are good, let's go to the following to learn about it.

1. Planting method

Sweet potatoes, corn and peanuts can be planted in the previous crop, followed by salvia miltiorrhiza, and tea orchards, orange orchards, mulberry orchards and intermediate crops can be planted in the middle, which is like semi-wild planting and growing well. Separate root planting, the plant remains in the ground, when you need to replant, you can take the lateral root to plant from February to March, but pay attention to cover the straw to prevent frost injury. Cuttage planting, take the strong stems on the ground to remove the lower leaves, oblique cultivation before transplanting. Sowing and propagation, strip sowing, film mulching and moisturizing, emergence and transplanting.

2. Temperature condition

Like the warm climate environment, if the temperature is low, the growth is very slow, the overall development is slow, in general, the annual average temperature of the most suitable place for growth is not less than 17 degrees, but the root can survive the winter at about 15 degrees below zero, so the span of temperature tolerance is relatively large. In general, the most suitable temperature for growth is about 15 to 18 degrees, below 28 degrees can grow very well, but more than 30 degrees, it is easy to affect some growth.

3. Lighting requirements

Salvia miltiorrhiza is a light-loving plant, which requires sufficient light during its growth period, but it grows slowly without enough light. Generally, Salvia miltiorrhiza grows in deciduous broad-leaved forests in temperate regions. So Salvia miltiorrhiza needs light, but can not accept strong light, strong light makes Salvia miltiorrhiza grow slowly, and the plant may lose water.

4. Soil conditions

Generally speaking, wild Salvia miltiorrhiza grows in woods, roadsides and hillsides. In fact, the soil in these places is relatively dry. Salvia miltiorrhiza is afraid of stagnant water, so it needs high-lying dry soil. Most like fertile, loose, sandy loam, for soil pH requirements are not strict, micro-acid, micro-alkali, neutral can be planted. Generally speaking, the fertile, dry and permeable soil is more suitable for planting.

The planting method of Salvia miltiorrhiza is mainly followed by the previous crop, tea garden and forest interplanting, the wild method is better, but the field planting provides good conditions for good growth and higher yield.
