Detailed Explanation of Cultivation Techniques for the Chinese Medicinal Herb Huangjing (Polygonatum), with Early Pest and Disease Prevention
Huangjing (Polygonatum) is currently one of the hottest Chinese medicinal herbs on the market, and many growers or buyers interested in Chinese medicine are probably quite familiar with it. Because of the sudden market boom, more and more people have been cultivating Huangjing over the past two years. Although Huangjing is easy to keep alive, producing a high-quality crop definitely still requires experience. We at the editorial team have also put together a summary of Huangjing cultivation techniques for everyone, so let's take a look!
Huangjing Cultivation Techniques
1. Site Selection
Huangjing is fairly strict when it comes to site selection. First of all, before planting, we need to be clear about what type of medicinal herb this roughly is: Huangjing prefers a shady environment, so when choosing a site, you can mark hillside positions that do not face the sun as key options. Half a month before transplanting the seedlings, you should begin the soil-turning work, mainly to clear weeds and add the first round of fertilizer. The fertilizer should be mainly organic mixed fertilizer, and you can use your usual amount. When planting, the land should be leveled into strips about 1.5 m wide, with each strip spaced about 20 cm apart, to facilitate drainage and daily management.
2. Seed and Seedling Management
Huangjing seeds need to be awakened (stratified), and friends with experience in this kind of cultivation should be very clear about that. The seed-awakening period is relatively long, and you can use this time to build a nursery bed for breeding. Prepare the sandy soil you will need in advance, because sandy soil has better water permeability, then select seeds and moisten them with water, and finally place them in the sandy soil. Remember not to bury them completely. The nursery should be watered regularly to keep it in a relatively moist state. After about 4-6 months, the seeds will basically be ready after awakening, and you can prepare to begin planting work.
3. Field Management
Once the seeds have sprouted, field management should begin. In the early stage, the main focus is on fertilizer and water, and on protection from strong light. Some base fertilizer needs to be prepared at the bottom of the seedlings. After planting the seedlings, control watering to once a week according to the degree of soil moisture, for about one month, and then take measures to provide shade. Generally, in the first month after Huangjing sprouts, weeds will begin to appear in the field, and you will need to carry out weeding work, using pesticides to remove these weeds. Later on, you can do appropriate clearing once each quarter.
4. Pest and Disease Prevention
Pest and disease problems in Huangjing are not serious, but they cannot be ignored either. If Huangjing is managed very well, the probability of pests and diseases will certainly be somewhat lower. However, root rot is still unavoidable in the growing environment, mainly caused by excessive watering. Here, the editorial team reminds farmers that watering should still be based on the actual degree of soil moisture, and it is not necessary to water according to a fixed schedule. Its symptoms are a tendency for the plant to wither and black rot at the roots, and it can be treated with metalaxyl and hymexazol.
