What problems should be paid attention to in Rhizoma Polygonatum cultivation

With the decrease of wild resources, but the increase of demand for medicinal materials, artificial cultivation of medicinal materials has also become a well-known project. The Polygonatum odoratum planting project has triggered a wave of enthusiasm in the market in recent years, driving many people into this industry, but many people do not have professional planting technology, so there are many problems in the process of planting. So today's small series will give you a brief introduction to the points that need to be paid attention to in the planting process according to the problems that everyone has. Let's take a look together.

1. Soil

Polygonatum has certain requirements for the soil of planting land. Only suitable soil conditions can Polygonatum grow and develop better. Polygonatum suitable for fertile soil, deep soil layer, rich in organic matter in humus soil planting. Of course, if there is no such soil, you can also settle for the next step, consider sandy loam. Another point we should pay attention to is that when preparing the soil, we should clean up the impurities in the soil and disinfect the soil, so that the quality of polygonatum planted in this way is better.

2. Time

The time of polygonatum cultivation is also a problem we have to consider, because not all the time is suitable for polygonatum cultivation. If rootstock propagation is used, we usually dig the tubers of Polygonatum sibiricum from November of the first year to March of the following year, and plant them after the surface temperature rises. However, if it is seed reproduction, it is generally harvested in August, sand storage treatment, and sowing in March of the following year.

3. Moisture

Polygonatum in the growth process of water demand is large, but each watering also needs to control the amount of water, the humidity in the field should not be too large, otherwise it will cause root rot, anthracnose, leaf spot and other diseases. We only need to water frequently to keep the soil moist, and the general humidity can be kept at about 50%. At the same time, according to the different growth periods of Polygonatum odoratum, we can reasonably control the amount of watering. Watering in dry times and draining in rainy times to avoid standing water in the field.

4. Nutrients

In order to ensure the quality and yield of Polygonatum sibiricum, the management of nutrients is crucial. In the growth period of Polygonatum sibiricum seedlings, we should follow the principle of frequent fertilization to promote the growth of seedlings, but we should not apply nitrogen fertilizer to avoid excessive growth of branches and leaves, affecting the growth of underground tubers. In the later growth process, cake fertilizer was mainly used to promote the growth of Polygonatum sibiricum tubers and achieve the purpose of increasing production.

5. Light

Polygonatum is a kind of plant that likes shade, but this does not mean that its growth does not require light. Under normal circumstances, when we choose planting sites, we will choose semi-shady and semi-sunny areas, or areas with shade near planting sites, which have congenital planting advantages. Secondly, we can set up shade shed in the process of planting, but we should adopt transparent type to avoid direct sunlight, so as to ensure that there is certain light in the field, which is more conducive to the growth of Polygonatum sibiricum.

In fact, the most important thing about polygonatum cultivation is to be serious, and the requirements for all aspects of it should be stricter. Secondly, we should pay great attention to the selection of soil and seeds and tubers. The most important thing is scientific planting technology and reasonable management technology, which are the keys to the success of Polygonatum cultivation.
