Detailed Explanation of the Latest Key Points for Field Management of Chuanxiong

Chuanxiong is a perennial herbaceous plant in the Apiaceae family, with a relatively strong root growth capacity and a rather rich fragrance. It has a wide planting area in China, and when cultivating Chuanxiong, management work is very important. A reasonable field management technique is the key to ensuring the yield and quality of Chuanxiong. So how should Chuanxiong be managed when planted? Below, the editor brings you the key points for field management of Chuanxiong. Let's take a look!

1. Intertillage and Weeding

Intertillage and weeding are very important for the growth of Chuanxiong. After the seedlings have successfully emerged uniformly, a timely shallow intertillage and hoeing should be carried out once. Then about 3 weeks later, intertillage and weeding should be carried out again. During intertillage, pay attention to the depth; it should not be too deep, to prevent damaging the roots of Chuanxiong and affecting growth. During the vigorous growth period of the underground rhizomes, a 3rd intertillage should be carried out. In the process of planting Chuanxiong, intertillage should be carried out at least 4 times, with the last time in the spring of the second year. Before intertillage, pay attention to clearing old stems and leaves in the field; after completion, earth up around the roots to improve the cold resistance of the rhizomes and promote the rhizomes' overwintering.

2. Thinning and Final Singling of Seedlings

Thinning is to prevent healthy, vigorously growing seedlings from crowding each other, competing with each other for the nutrients and water needed for growth, and affecting normal growth. Generally, when the seedlings grow to about 12 cm in March to April each year, the work of thinning and final singling should be carried out carefully. During thinning, pay attention to the growth condition of the seedlings. Choose healthy seedlings free of pests and diseases, and remove weak and poorly growing seedlings. Then control the planting density well and do the final singling work properly. It must not be too dense, otherwise the thinning and final singling work will lose its effect. Keep about 10 seedlings per hole.

3. Reasonable Fertilization

In the first two years of planting Chuanxiong, its aboveground part grows relatively vigorously, and the formation of the nutrient area is relatively fast. Only by producing a large amount of dry matter can sufficient nutrient growth of the rhizomes be ensured. Therefore, when planting Chuanxiong, we should pay attention to doing a good job in fertilization. Within the first two months before planting, topdressing should be carried out at least about 3 times, and each topdressing can be carried out together with intertillage and weeding. The fertilizer should mainly be decomposed farmyard manure, applied at the hole opening position of the plants. Generally, all of it should be applied before Frost's Descent to ensure the effect.

4. Timely Harvesting

The harvesting season for Chuanxiong is generally most suitable within about one week around Grain Full in the second year of planting. The harvesting time should not be too early or too late. If too early, the underground rhizomes have not yet fully matured, which will have a certain impact on yield. However, if harvested too late, the rhizomes will be overmature and extremely prone to rotting underground, also causing a decline in yield and affecting the economic benefits of planting. When harvesting, pay attention to choosing a sunny day; it must not be carried out on rainy days. Dig out the whole plant, then remove the stems and leaves, remove the soil, dry it slightly for 2-3 hours, and then process it for market.

The above is a brief introduction to the key points for field management of Chuanxiong. The pest and disease control management work for Chuanxiong is also very important. Common pests and diseases include root rot, stem node moth, and others, which will harm the growth of Chuanxiong plants to varying degrees.
