Polygonatum planting and management: how and when to plant Polygonatum? What problems should be paid attention to in Rhizoma Polygonatum cultivation

With the decrease of wild resources, but the growth of demand for medicinal materials, artificial cultivation of medicinal materials has become a tacit project to get rich. Polygonatum planting project has triggered an upsurge in the market in recent years, driving a lot of people into the industry, but many people do not have professional planting technology, so there are a lot of problems in the planting process. Well, today, according to the problems that have arisen, the editor will briefly introduce to you a few points that Huang Jing needs to pay attention to in the process of planting. Let's take a look.

1. Soil

Polygonatum polygonatum has certain requirements on the soil of the planting land, and only under suitable soil conditions can Polygonatum grow and develop better. Polygonatum polygonatum is suitable for planting in humus soil with fertile soil, deep soil layer and rich organic matter. Of course, if there is no such soil, we can also consider sandy loam. Another point we 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 is better.

2. Time

The planting time of Polygonatum polygonatum is also an issue that we have to consider, because not all the time is suitable for the cultivation of Polygonatum. If we use rhizome propagation, we usually dig up Polygonatum tubers from November of the first year to March of the next year, and after treatment, we can plant them after the surface temperature rises. However, if the seeds are propagated, the seeds are usually collected in August, treated with sand storage, and then sown in March of the following year.

3. Moisture

Rhizoma Polygonatum has a large demand for water in the process of growth, but each watering also needs to control the amount of water, and the humidity in the field should not be too high, otherwise it will cause root rot, anthracnose, leaf spot and other diseases. We only need to water regularly to keep the soil moist, and the general humidity can be kept at about 50%. At the same time, according to the different water needs of Polygonatum in different growth periods, we can reasonably control the amount of water. Water in dry times and drain in rainy times to avoid stagnant water in the fields.

4. Nutrients

In order to ensure the quality and yield of Polygonatum polygonatum, the management of nutrients is also very important. In the growth period of Polygonatum seedlings, we should follow the principle of frequent fertilization to promote the growth of seedlings, but not partial application of nitrogen fertilizer, so as not to grow branches and leaves and affect the growth of underground tubers. In the later growth process, mainly cake fertilizer, to promote the growth of Polygonatum tuber, in order to achieve the purpose of increasing production.

5. Lighting

Polygonatum is a negative plant, but that doesn't mean it doesn't need light to grow. In general, when we choose the planting site, we will choose the semi-overcast and semi-sunny area, or the area with shade near the planting site, which has a congenital planting advantage. Secondly, we can build a shade shed in the process of planting, but we should use a transparent one to avoid direct sunlight, which can also ensure that there is a certain amount of light in the field, which is more conducive to the growth of Polygonatum.

In fact, the most important thing in the cultivation of Polygonatum is to be serious and strict in all aspects of it. 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 key to the success of Polygonatum cultivation.
