What should be paid attention to in the latest planting of Prunella vulgaris

Prunella vulgaris is very common in many places in rural areas. most of the time, it is used for soaking water, and it has high medicinal value, and it is also a kind of medicine that is very easy to feed, because it does not have too many requirements for the growing environment. Prunella vulgaris can be seen in many places, but in recent years, the demand for Prunella vulgaris has increased, coupled with the destruction of the environment, so slowly began to plant Prunella vulgaris artificially. So what do you need to pay attention to when growing Prunella vulgaris? Let's take a look.

1. Soil

Wild Prunella vulgaris has no requirements for the planting environment, but when we carry out artificial planting, we are mainly in order to grow high-yield and high-quality medicinal materials, in order to obtain higher economic benefits, so we need to choose a good planting site when planting. It is generally appropriate to choose loam or humus with sufficient light, fertile soil and good drainage and storage, rather than heavy clay for planting.

2. Time

The planting time of Prunella vulgaris we need to choose the best planting time according to the mature time of Prunella vulgaris seeds and its growth habits. usually we will choose to plant in August and September every autumn. at this time, the budding rate of Prunella vulgaris is fast, and the growth rate is fast, at the same time, it is convenient to manage, and there are relatively few diseases and insect pests. The second is that if you miss planting in autumn, you can also sow in spring, but the yield is high every autumn.

3. Density

There are two main ways to sow Prunella vulgaris, which are strip sowing and sowing. Strip sowing requires us to first trench the whole land at an interval of about 15 to 25 cm per row, and then sprinkle the seeds evenly in the ditch and cover the seeds with soil. Sowing is to sow directly, and what we should pay attention to after emergence is the need for inter-seedling and supplementary seedlings. The seedlings are usually carried out according to about 20 cm per row and 15 cm per plant, and reasonable density is a basic condition for high yield. secondly, we also need to divide the specific density according to the fertility of the soil and the varieties of Prunella vulgaris.

4. Fertilizer and water

Fertilizer and water management is not only a very important point in field management, but also the key to the high yield of Prunella vulgaris. We need to top fertilizer according to the growth of Prunella vulgaris. After planting, we need topdressing, which can be irrigated with fecal and urine water. This can promote the growth of Prunella vulgaris. Secondly, when the seedlings grow to about 15 cm, the most appropriate amount of phosphate fertilizer and calcium fertilizer, at the same time, should be combined with watering. The last thing to pay attention to is not only to maintain the humidity in the field, but also to drain waterlogging in time.

5. Diseases and insect pests

The resistance of Prunella vulgaris is very strong, and it is rarely affected by diseases and insect pests in the whole process of its growth. If there are diseases and pests that harm the branches and leaves of Prunella vulgaris, such as blight and aphids, we can usually use Bordeaux solution to control the disease, and we can also use yellow boards to trap aphids or spray them with trichlorfon solution. But it should be noted that chemical control can not be carried out from half a month to one month before harvest, which will seriously affect the quality of Prunella vulgaris.
