Detailed Explanation of Key Points of Paris polyphylla Seed Propagation Techniques
Paris polyphylla, also known as Qiye Yizhihua (seven leaves and one flower), generally uses its rhizome as the medicinal part, and it is mainly cultivated in Yunnan, Guizhou and other places in China. There are two propagation methods for Paris polyphylla, namely seed propagation and division propagation. Today, the editor will introduce the seed propagation techniques of Paris polyphylla. Let's take a look below.
1. Seed Selection
If you are keeping your own Paris polyphylla seeds, they can generally be harvested in September and October. After harvesting, the pulp and seeds should be separated, and seeds with high yield, good quality, plump grains, maturity, no pests or diseases, no mildew and no mechanical damage should be selected for planting. If the seeds are purchased, then we only need to choose excellent Paris polyphylla varieties, because such seeds are all processed and treated seeds, and their seedling emergence rate is relatively high.
2. Seed Treatment
After the self-retained seeds are screened, they need to be stored in warm sand at room temperature for about 25 to 30 days. Then, after the warm sand treatment is completed, low-temperature treatment is carried out, which can promote the sprouting speed of the seeds. The temperature for low-temperature treatment is generally about 3 to 5 degrees, and the storage time is also about 25 to 30 days. During the treatment process, turn them over about once a week to check whether there is any mildew. After the low-temperature treatment, soak the seeds in a chemical agent to increase the rooting speed of the seeds. Finally, place the seeds at a constant temperature of about 20 degrees for sprouting. During the sprouting process, spray water appropriately to maintain the humidity of the seeds, and after about one and a half months, they can be sown.
3. Sowing and Propagation
Two sowing methods can generally be used for Paris polyphylla seeds, namely drilling and broadcasting. Drilling is beneficial to later field management work, while broadcasting is relatively simple during the sowing process. The spacing between rows is generally about 5 cm, then the seeds are evenly scattered in the furrows, and finally covered with soil. For broadcasting, first level the ground, scatter the seeds evenly, and finally gently press the seeds into the soil so that the seeds are not exposed above the ground.
4. Seedling Stage Management
After sowing, a layer of dead leaves can be covered on top, and water should be added. An appropriate amount of nutrient solution can be added to the water, which is beneficial for the seeds to absorb nutrients and sprout quickly. Before emergence, water at least 3 to 4 times, and at the same time build a shade shed before emergence; also, fertilize reasonably, mainly with organic fertilizer. Finally, do a good job in pest and disease control, among which the most important are underground pests and root rot and damping-off disease. The underground pests are mainly cutworms and grubs, which can be poisoned with trichlorfon, while root rot and damping-off disease can be controlled with carbendazim.
Seed propagation of Paris polyphylla is the most traditional propagation method, and it is also the most practical propagation method. That is the end of the editor's sharing, and I hope it can help more friends who like to grow Paris polyphylla. If you have other questions to consult, remember to leave a message for the editor.
