Corydalis Planting Methods and Key Technical Points
Corydalis is a perennial herb in the Papaveraceae family and a traditional Chinese medicinal herb in our country, with the tuber being the main medicinal part. Its primary medicinal effect is pain relief, and it has the properties of dispersing with pungent warmth and draining with bitter cold. It is widely distributed across our country. At present, the planting area of corydalis 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. Let's take a look!
1. Land Selection and Preparation
The root system of corydalis is relatively shallow, usually not exceeding 20 cm in distribution, concentrated at around 15 cm. Therefore, before planting, we must select good soil, preferably soil that is soft in texture, with ample sunlight, and loose, fertile, and well-drained. It must not be overly moist and must 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, land preparation work must be done well by deep plowing to about 22 cm to improve soil softness, then making beds ready for planting.
2. Timely Planting
The main propagation method for corydalis is tuber propagation. The tubers should be plump, juicy, healthy, multi-budded tubers free of pests and diseases. Planting is generally carried out around October each year. When planting, attention must be paid to planting density, with plant and row spacing 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 before sowing. Sowing is mainly done in furrows, with two rows of seeds placed every 10 cm in each sowing furrow according to row spacing.
3. Field Management
Field management work is very important for the yield of corydalis, and the first thing to do well is fertilization. In addition to applying sufficient base fertilizer before planting, attention must also be paid to topdressing with winter fertilizer, seedling fertilizer, etc., to ensure the nutrients needed for corydalis growth are met. When fertilizing, it should also be combined with cultivating and weeding. Cultivating can prevent soil compaction, improve soil aeration, and enhance the plant's nutrient absorption. Proper weeding can prevent weeds from competing for the nutrients needed for corydalis growth, concentrating nutrients on the corydalis plants. Finally, reasonable watering is necessary. On the premise of ensuring corydalis has sufficient water, attention must also be paid to drainage work, especially during rainy periods, when there must be no water in the furrows; otherwise, corydalis is highly 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. Pests and diseases harm different organs of the corydalis plant, seriously hindering its growth and causing yield to decline 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 dosage to prevent waterlogging and fertilizer damage that could trigger pests and diseases. Common pests and diseases of corydalis include downy mildew, sclerotinia, etc. When carrying out pest and disease control, everyone should also pay attention to doing it in a targeted and purposeful manner.
The above is a brief introduction to corydalis planting methods. Corydalis 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, so they should not be underestimated. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
