What are the precautions for Polygonatum planting? A detailed explanation of the latest key growing points
With the decline of wild resources, but the growth in demand for medicinal materials, artificially cultivating medicinal materials has also become a wealth-building project that everyone tacitly understands. The Polygonatum planting project has triggered a wave of enthusiasm in the market in recent years, driving many people into this industry, but quite a few people do not have professional planting techniques, so quite a few problems have also appeared during the planting process. So today, based on the problems that have appeared for everyone, the editor will briefly introduce a few points that need attention during Polygonatum planting. Let's take a look together.
1. Soil
Polygonatum has certain requirements for the soil of the planting site. Only with suitable soil conditions can Polygonatum grow and develop better. Polygonatum is suitable for planting in humus soil that is fertile, has a deep soil layer, and is rich in organic matter. Of course, if this kind of soil is not available, you can also settle for the next best option and consider sandy loam. There is one more point we should note: when preparing the land, we need to clean out impurities in the soil and disinfect the soil, so that the Polygonatum grown will be of better quality.
2. Time
The time for Polygonatum planting is also an issue we need to consider, because not all times are suitable for Polygonatum planting. If rootstock propagation is used, we generally dig up Polygonatum tubers from November of the first year to March of the following year, and after processing, they can be planted once the surface temperature rises again. But if seed propagation is used, the seeds are generally harvested in August, treated by sand storage, and then sown in March of the following year.
3. Water
Polygonatum has a relatively large demand for water during its growth process, but the amount of water also needs to be controlled each time it is watered. The humidity in the field should not be too high, otherwise it will cause various diseases such as root rot, anthracnose, and leaf spot disease. We only need to water frequently to keep the soil moist. Generally, keeping the humidity at around 50 percent is sufficient. At the same time, according to Polygonatum's different water needs at different growth stages, we just need to reasonably control the amount of watering. Water during drought and drain during rainy periods to avoid water accumulation in the field.
4. Nutrients
In order to ensure the quality and yield of Polygonatum, nutrient management is also crucial. During the seedling growth period of Polygonatum, we should follow the principle of frequent fertilization to promote seedling growth, but we must not apply too much nitrogen fertilizer, so as to avoid excessive vegetative growth of branches and leaves, which affects the enlargement of underground tubers. In the later growth process, cake fertilizer is mainly used to promote the enlargement of Polygonatum tubers, so as to achieve the goal of increasing yield.
5. Light
Polygonatum is a shade-loving plant, but this does not mean that its growth does not need light. Under normal circumstances, when choosing a planting site, we choose a half-shade and half-sun area, or an area with shade objects nearby. Such areas have innate planting advantages. Secondly, during the planting process, we can build a shade shed, but it should be a transparent type to avoid direct sunlight. This can also ensure that the field has a certain amount of light, which is more conducive to the growth of Polygonatum.
In fact, the most important thing in Polygonatum planting is to be careful, and the requirements in all aspects should be relatively strict. Secondly, we should also pay great attention to the selection of soil as well as the selection of seeds and tubers. The most important thing is scientific planting techniques and reasonable management techniques. These are the key to successful Polygonatum planting.
