How to Grow Gentian? A Detailed Explanation of Planting Methods and Key Technical Points
Gentian can be abbreviated as gentian, and it can also be called dan cao. It is a perennial herbaceous plant of the Gentianaceae family and can be grown in most areas of our country. For example, Inner Mongolia, Jilin, Guizhou, Hunan, Guangdong, and other places. Wild gentian generally grows in grasslands, roadsides, and other places, so how do you grow gentian artificially? Below are the planting methods for gentian. Let's learn together.
1. Site Selection and Land Preparation
Gentian has the characteristics of liking moisture and coolness, and its requirements for the planting site are not high. Usually, a relatively moist plot with sufficient water sources is chosen; the planting site should be relatively flat with sufficient sunlight. The best soil is sandy loam, and it should contain rich organic matter with relatively sufficient soil fertility. Clay soil and heavy clay soil are taboo. Before sowing, carry out land preparation by deeply plowing the land, combining it with fertilization, mixing the base fertilizer evenly, applying base fertilizer heavily, leveling the soil surface, breaking up soil clods finely, and then opening furrows and making beds.
2. Planting Methods
There are two methods for planting gentian, namely seed propagation and division propagation. Seed propagation can generally be done in spring sowing and autumn sowing. For spring sowing, the seeds need to be treated and then sown, while autumn sowing is carried out in November each year. When sowing, use the drill method, with a distance of 35 cm between rows and 15 cm between plants. Division propagation is carried out in April each year, and planting is done according to the spacing used for seed propagation.
3. Planting Management
After planting, it is mainly necessary to maintain soil moisture and water irregularly. Next, weed in a timely manner. There is no limit to the number of times for weeding in gentian cultivation; we mainly carry out early summer weeding according to the growth of weeds and remove weeds as early as possible. Next, gentian needs to be watered frequently, so in order to prevent soil compaction, it is necessary to loosen the soil and earth up the soil to improve soil permeability. Also, in order to promote the growth of gentian, we need to topdress in a timely manner. First, spray foliar fertilizer, generally about two times. Second, apply cake fertilizer, phosphate fertilizer, and farmyard manure in furrows. Finally, note that in order to improve the yield and quality of gentian and reduce nutrient consumption, it is necessary to thin flowers and remove flower buds, so that nutrients can be supplied in a concentrated way and the growth of rhizomes can be promoted.
4. Pest and Disease Control
The main disease of gentian is leaf spot disease, which mainly harms the leaf surface of the plant and ultimately causes the leaves to wither and die. So first, we need to disinfect the soil. Second, disinfect the gentian seedlings. Then, reasonably control the planting density. Also, use chemicals for control, mainly mancozeb or sandofan. Finally, destroy diseased plants, thoroughly remove the soil near the diseased plants, replace the soil, and completely solve the problem from the source of infection.
Gentian is actually very common in our lives, but for people who do not recognize it, it is just a wild grass or weed. So its vitality is very tenacious, and naturally it is relatively easy to grow and also easy to survive. That is all for today's sharing from the editor.
