Latest Planting Methods and Key Cultivation Techniques for Corydalis yanhusuo
Corydalis yanhusuo is a perennial herbaceous plant of the Papaveraceae family and a traditional Chinese medicinal herb in our country, with the tuber as its main medicinal part. Its primary medicinal effect is pain relief, and it has the properties of dispersing with pungent warmth and clearing with bitter purging; it is widely distributed across our country. At present, the planting area of Corydalis yanhusuo in our country is continuously expanding, but many people still do not know exactly how to grow it. Below, the editor brings you the planting methods for Corydalis yanhusuo. Let's take a look!
1. Land Selection and Preparation
The root system of Corydalis yanhusuo is relatively shallow, usually not extending beyond 20 cm, and concentrated at around 15 cm. Therefore, before planting, we must select good soil, preferably soft-textured, sunny, well-drained and fertile soil. It must not be overly moist and should have good drainage and irrigation capacity, rich in humus, etc. It should not be planted in clay or heavily sandy soil, and proper crop rotation should be practiced. After selecting the land, do a good job of land preparation by deep plowing about 22 cm to improve soil looseness, then make beds ready for planting.
2. Timely Planting
The main propagation method of Corydalis yanhusuo is tuber propagation. The tubers should be plump, juicy, healthy, multi-budded, and free of pests and diseases. Planting is generally carried out around October each year. When planting, pay attention to planting density; the plant and row spacing should be maintained at more than 10 cm. However, before planting, the tubers should be cut into small sections of about 1.5 cm, then placed in a solution such as Tuzet for disinfection, soaked for about 12 minutes, then removed and dried in preparation for sowing. Sowing is mainly done in furrows, with two rows of seeds placed every 10 cm in each sowing furrow according to the row spacing.
3. Field Management
Field management work is very important for the yield of Corydalis yanhusuo. First of all, do a good job of fertilizing. In addition to applying sufficient base fertilizer before planting, also pay attention to topdressing with winter fertilizer, seedling fertilizer, etc., to ensure the nutrients needed for the growth of Corydalis yanhusuo are met. When fertilizing, it should also be combined with intertillage and weeding. Intertillage can prevent soil compaction, improve soil permeability, and enhance the plant's nutrient absorption. Proper weeding can prevent weeds from competing for the nutrients needed for the growth of Corydalis yanhusuo, concentrating the nutrients on the Corydalis yanhusuo plants. Finally, water reasonably. On the premise of ensuring sufficient water for Corydalis yanhusuo, also pay attention to drainage, especially during rainy days. There must be no water in the furrows; otherwise, Corydalis yanhusuo is very prone to root rot, leading to reduced yield.
4. Pest and Disease Control
Pest and disease control is very important for the growth of Corydalis yanhusuo. Pests and diseases harm different organs of the Corydalis yanhusuo plant, seriously hindering its growth and reducing yield accordingly. Therefore, during the planting process, we must do a good job of pest and disease control, strengthen field management, water and fertilize in a timely manner, and pay attention to the amounts used, to prevent waterlogging and fertilizer damage that could trigger pests and diseases. Common pests and diseases of Corydalis yanhusuo include downy mildew, sclerotinia, etc. When carrying out pest and disease control, everyone should also pay attention to doing so in a targeted and purposeful manner.
The above is a brief introduction to the planting methods of Corydalis yanhusuo. Corydalis yanhusuo has relatively strong growth ability and is relatively simple to plant and manage. The main thing is still to pay attention to pest and disease control, because pests and diseases can cause fatal harm to the growth of Corydalis yanhusuo, so they should not be underestimated. That's all for today's introduction. This article is for reference only, and we hope it can help everyone!
