Notes on cultivation of figwort

Radix scrophulariae is also called black ginseng, and it is also called sheep's horn ginseng in some areas. it is mainly used for heat-clearing and detoxification and nourishing yin and so on. It has a strong ability to adapt to the environment, and it is relatively simple to grow. In China, it is mainly in Hunan, Hubei, Guangzhou, Chongqing and other places. But there are a lot of things to pay attention to when planting Radix scrophulariae, so let's take a look at its planting precautions.

1. Time

The planting time of Radix scrophulariae is mainly related to the climate of the planting place, generally, the southern region can be divided into two periods of spring and autumn, and the northern region needs to be considered as appropriate. Spring planting is usually around February, while autumn sowing is usually between October and November. But generally consider sowing in autumn, the yield and quality of sowing in autumn will be better than that of sowing in spring.

2. Soil

The cultivation of Radix scrophulariae does not require too much soil, but there are still a few points to pay attention to. First of all, the soil layer should be relatively deep, while the permeability and drainage are good. The second is to plant in places with plenty of light, and the soil is fertile, because Radix scrophulariae likes the sun and has strong ability to absorb fertilizer. Finally, the land of continuous cropping can not be selected, and the best front crop is legumes.

3. Weeding

When weeding, we should pay attention to loosen the soil not too deep, so as not to hurt the roots of Radix scrophulariae. In general, weeding is carried out when Radix scrophulariae emerges, followed by weeding four to six times from sowing to harvest. When the plant grows to a certain size, there is no need for intertillage, as long as the weeds growing in the field can be pulled out by hand.

4. Density

If you use the method of seed sowing, it is generally necessary to carry out two or three seedlings to achieve a reasonable density, and if you plant in other ways, then you need to plan the density reasonably when planting. In general, the final reference standard is the row spacing of 40 cm and the plant spacing of about 35 cm.

5. Fertilizer and water

Three times of topdressing is generally needed in the growth process of Radix scrophulariae. The first time is after the emergence of the seedlings, mainly urea, according to the degree of fertility in the field to a reasonable amount to promote the growth of seedlings. The second time is the peak growth period of Radix scrophulariae, and this time we need to add an appropriate amount of barnyard manure on the basis of the use of urea. The third fertilization is in the flowering stage of Radix scrophulariae, mainly to promote the growth of Scrophularia tuber, generally mainly potash fertilizer and phosphate fertilizer. Radix scrophulariae has a strong ability to resist drought, so it generally does not need watering.

6. Topping

In order to obtain higher economic benefits and make Scrophularia grow better, we need to remove the bud in time and remove the top of it at the same time to avoid overgrowth. In this way, nutrients can be concentrated and absorbed by its tubers, promote the rapid growth of fast forward, and increase the yield of Radix scrophulariae.
