What are the latest planting precautions for Saussurea lappa

Saussurea lappa is a perennial herb in the Asteraceae family and also a type of traditional Chinese medicinal material. It is currently mainly distributed in Yunnan, Sichuan, and Guizhou in China. Saussurea lappa can reproduce both sexually and asexually. So today we will mainly learn about some precautions to pay attention to during the planting process of Saussurea lappa.

1. Soil

Saussurea lappa has certain requirements for the soil of the planting site. Generally, it is best to choose land whose previous crop was corn, Codonopsis, or similar crops. Next, the planting site should have good drainage and permeability, and the soil should be rich in humus. Black soil with sufficient soil fertility is best. In order to prevent the aroma of the Saussurea lappa roots from attracting underground pests, we need to apply an appropriate amount of sheep manure and barnyard manure, and make the land into high ridges.

2. Seeds

If Saussurea lappa is planted by seed propagation, then we need to treat the seeds so as to ensure its emergence rate and later survival rate. Before sowing, we need to soak the seeds in warm water at about 30 degrees for about 24 hours, then select plump seeds without impurities, dry them in the shade, and then mix the seeds with chemicals before sowing.

3. Seedling fixing

After Saussurea lappa emerges, what we need to do is fix the seedlings. Generally, when the Saussurea lappa seedlings grow to about 8 to 10 cm, we need to transplant the seedlings and fill in missing seedlings and thin the seedlings. When planting, each planting hole needs to have two seedlings placed in it, and the planting amount per mu is about 15,000 plants.

4. Bud removal

The growth cycle of Saussurea lappa is about two years, which means it will bloom after two years. So in order to avoid the loss of nutrients, allow nutrients to be supplied in a concentrated way, promote root growth, and increase the yield of Saussurea lappa, we need to remove both its flower buds and flower buds when it blooms. However, it should be noted that those used for seed retention should not have their flower buds removed, while all the rest should have their flower buds completely removed.

5. Fertilizer and water

Saussurea lappa likes fertilizer and has a relatively large demand for nutrients, so topdressing should be carried out reasonably during the planting process. It also does not have high requirements for fertilizer types; generally, farmyard manure, organic fertilizer, and chemical fertilizer can all be used. But we still need to pay attention to some matters, for example, farmyard manure is best based on manure and urine, plant ash, and cake fertilizer; chemical fertilizer is best based on phosphate fertilizer and urea, and after fertilizing, irrigation should be carried out to avoid burning the seedlings. Finally, what we need to pay attention to is the watering of Saussurea lappa. Watering especially in spring is more conducive to the growth of Saussurea lappa, so we should irrigate reasonably, but also control the amount of watering. Secondly, during the rainy season, drainage should also be carried out in time. If the field humidity is too high, it may cause root rot of Saussurea lappa and cause irreparable losses.

Saussurea lappa is not only a medicinal material, but its ornamental value is also very high, so its use value and economic value in the market are also relatively high. There are also many issues we need to pay attention to during the planting process, but these few shared with everyone by the editor are places that are easily overlooked or prone to misunderstandings during the planting process. Everyone can read and understand them carefully.
