How to manage planting polygonatum

Polygonatum odoratum is not only a perennial herb of Liliaceae, but also a commonly used traditional Chinese medicine. At present, the main varieties of Polygonatum odoratum are Hunan Polygonatum odoratum, Haimen Polygonatum odoratum and Western Polygonatum odoratum. At the same time, there are two common wild varieties: Polygonatum odoratum and Jiangbei Polygonatum odoratum. In fact, the planting technology of Polygonatum odoratum is very simple, but if you want to have a high yield, don't let go of its management skills. So what we are going to learn today is the planting management technology of Polygonatum odoratum. Let's take a look.

1. Density management

Polygonatum odoratum is usually planted in April or October every year, and when planting, its planting density is also worthy of our attention. With reasonable planting density, it can avoid some diseases to a great extent. Generally speaking, the planting density row spacing is preferably 30 to 40 cm, and the plant spacing is 15 to 20 cm. At the same time, it is more convenient for us to operate in the field, and it can also reduce a certain amount of labor.

2. Ploughing and weeding

The growth cycle of Polygonatum odoratum is long, generally, it will not emerge in the first year after planting, but will not emerge until the spring of the second year. After the emergence of Polygonatum odoratum, we will start ploughing and weeding. At the beginning of weeding, we all use shallow ploughing or pulling out weeds to ensure that there are no weeds in the field. Wait until the third year, its rhizome growth distribution is dense, in order to avoid damage to tubers, can only pull weeds, if the land is hardened, then it is necessary to loosen the soil and cultivate the soil properly, so as not to affect the yield of Polygonatum odoratum.

3. Fertilizer and water management

Although Polygonatum odoratum is a high-fertilizer and high-yield plant, there is no need for topdressing in the first year when the base fertilizer is fully applied. But if the growth rate of Polygonatum odoratum is very slow, and the leaves turn yellow, it is usually malnutrition, then it means to apply fertilizer. When we are topdressing, we mainly use feces and urine water, and use soil fertilizer, cake fertilizer, phosphate fertilizer and so on. We should pay attention not to use nitrogen fertilizer as much as possible, because Polygonatum odoratum is very sensitive to nitrogen fertilizer. In the growth process of Polygonatum odoratum, we should irregularly water it, the specific situation according to the precipitation of planting and the growth of Polygonatum odoratum to determine, when necessary, timely drainage treatment.

4. Disease and pest control

In the process of planting, we also need to pay attention to the prevention and control of diseases and insect pests. For example, leaf spot, root rot, gray spot, purple verticillium these four diseases are relatively common, we can use Bordeaux liquid, carbendazim, chlorothalonil, trichlorfon and other agents to control. Secondly, the harm of grubs to Polygonatum odoratum is relatively great, so we should spray it in time so as not to affect the yield and quality of Polygonatum odoratum.

These are all the contents that the editor wants to share with you today. I believe you also have a certain understanding of the planting management technology of Polygonatum odoratum. At the same time, the editor also hopes to help more friends in need. If you have anything else to add, or other planting techniques to consult, you can also leave us a message.
