What precautions are there for growing Scrophularia ningpoensis? Explained in one article

Scrophularia ningpoensis is also called black ginseng, and in some regions it is also called yangjiao shen. It is mainly used for clearing heat and detoxifying as well as nourishing yin. It has strong adaptability to the environment and is relatively simple to grow. In China, it is mainly grown in places such as Hunan, Hubei, Guangzhou and Chongqing. However, there are also many points to note when growing Scrophularia ningpoensis. Below we will take a look at the precautions for growing it.

1. Time

The time for planting Scrophularia ningpoensis mainly depends on the climate of the planting site. Generally, southern regions can divide planting into two periods, spring and autumn, while northern regions need to consider it according to the situation. Spring planting is generally around February, while autumn sowing is generally between October and November. However, autumn sowing is generally considered, and the yield and quality of autumn sowing are better than those of spring sowing.

2. Soil

Scrophularia ningpoensis does not have many requirements for soil, but there are still a few points to note. First, the soil layer should be relatively deep, and at the same time have good permeability and drainage. Second, it should be planted in a place with sufficient sunlight, and the soil should have sufficient fertility, because Scrophularia ningpoensis likes sunlight and has a strong ability to absorb nutrients. Finally, land that has been continuously cropped cannot be chosen, and it is best if the previous crop was a legume plant.

3. Weeding

When weeding, be careful not to loosen the soil too deeply, so as not to damage the rhizome of Scrophularia ningpoensis. Generally, weeding is carried out when Scrophularia ningpoensis seedlings emerge. Second, from sowing to harvest, four to six weedings are generally needed. When the plants have grown to a certain size, intertillage is no longer needed; simply pull out the weeds growing in the field by hand.

4. Density

If the seed sowing method is used, then generally two or three thinnings are needed to achieve a reasonable density, while if other planting methods are used, then the density needs to be reasonably planned at the time of planting. In general, the final reference standard is a row spacing of 40 cm and a plant spacing of about 35 cm.

5. Fertilizer and water

During the growth process of Scrophularia ningpoensis, three topdressings are generally needed. The first is after the seedlings have all emerged, mainly using urea, with the amount reasonably determined according to the fertility of the field, to promote the growth of the seedlings. The second is during the vigorous growth period of Scrophularia ningpoensis; this time, on the basis of using urea, an appropriate amount of barnyard manure also needs to be added. The third fertilization is during the flowering period of Scrophularia ningpoensis, mainly to promote the growth of its tubers, generally mainly using potassium fertilizer and phosphorus fertilizer. Scrophularia ningpoensis has strong drought resistance, so watering is generally not needed.

6. Topping

When Scrophularia ningpoensis sprouts flower buds, in order to obtain higher economic benefits and let Scrophularia ningpoensis grow better, we need to promptly remove the flower buds and also remove its top to avoid excessive vegetative growth. In this way, nutrients can be concentrated and absorbed by its tubers, promoting rapid growth and increasing the yield of Scrophularia ningpoensis.
