The latest high-yield planting method of Salvia miltiorrhiza

With the further development of the medicinal value of Salvia miltiorrhiza, the economic value of Salvia miltiorrhiza becomes more and more considerable, and the wild Salvia miltiorrhiza which is a little longer in the wild is basically excavated, so the number of people planting Salvia miltiorrhiza is slowly increasing, which means that if they do not improve the quality of Salvia miltiorrhiza and increase the output of Salvia miltiorrhiza, the market will be occupied by someone else. So today, pro-agricultural network has brought you a high-yield planting method of Salvia miltiorrhiza, let's take a look at it.

1. Scientific selection of land

The growth of Salvia miltiorrhiza needs enough light, and the annual temperature had better be kept at about 20 to 25 degrees Celsius. If the previous planting technology is not perfect, then Salvia miltiorrhiza is only suitable for planting in Guangzhou and other places. But now many places can be planted, but there are still requirements for the choice of planting land. If you want high yield, then the planting land had better not be polluted for a year or two. In the mountains and gentle slopes with sufficient soil fertility, perfect drainage system and sufficient light, the land with loose soil, strong permeability and moderate soil acidity and alkalinity is the most suitable.

2. Planting mode

There are three sowing methods of Salvia miltiorrhiza, seed propagation, root propagation and cutting propagation, each of which has its own advantages. If it is propagated with seeds, it is necessary to treat the seeds. This can not only promote seed germination but also enhance the resistance of plants. For root propagation, we need to choose high-quality roots for planting. For example, if tubers are stout and without scars and diseases, they are of high quality. Cutting propagation is to select the better stem of Salvia miltiorrhiza and cut it into nodes, and then cuttage, each section must leave a few leaves, so the survival rate will be much higher.

3. Reasonable density

The planting density also affects the yield of Salvia miltiorrhiza. If the plant is too dense, the moisture in the field will be heavier, and the ventilation, ventilation and light permeability will not be very good, and all the reasonable light can not be carried out at all. In this way, the growth rate of Salvia miltiorrhiza is slow, and even some bacteria and viruses are derived, which lead to some unnecessary problems in the plant. Therefore, the best planting density of Salvia miltiorrhiza is about 600 plants per mu of land, with an average distance of 20 cm per row and about 10 cm between each plant.

4. Fertilizer and water management

We need to top fertilize Salvia miltiorrhiza at least three times a year, the first time is after planting, in order to promote the growth rate of the plant, the second time is when Salvia miltiorrhiza grows to 20 centimeters, that is, in April and May every year, the last time is usually during the flowering of Salvia miltiorrhiza, that is, around summer and July every year, it is best to use organic fertilizer or farm manure. This kind of colleagues who promote the growth of Salvia miltiorrhiza can also improve the medicinal properties of Salvia miltiorrhiza. In general, we do not use chemical fertilizer. Although the effect of chemical fertilizer is better, it has a great impact on the quality of Salvia miltiorrhiza. In other words, it is possible that a small piece of Salvia miltiorrhiza can solve the problem, which may take more than a dozen pieces to solve. Finally, water management is also a more important link, although Salvia miltiorrhiza needs water, but the water should not be too much, we need to set up a good ditch in the field, so it is convenient for us to water and drain when necessary.

5. Weeding and flower management

The growth of Salvia miltiorrhiza is relatively slow, so we can also remove weeds and loosen the soil from time to time, which can enhance the soil permeability, accelerate the growth rate of Salvia miltiorrhiza, and enhance the disease resistance of the plant. Finally, the key point is that in the florescence of Salvia miltiorrhiza, we need to remove some of the flowers, which can reduce unnecessary nutrient consumption and increase the yield of Salvia miltiorrhiza.
