What should be paid attention to when planting Polygonatum odoratum

Polygonatum odoratum is a kind of Liliaceae, mainly because its branches and leaves are very similar to lilies, but the underground tubers are completely different. Although they all have nourishing effects, Polygonatum odoratum is not as well known as lilies. But we can not deny its value, it also accounts for a large proportion in traditional Chinese medicine, and the scope of use is relatively wide. And in recent years, the cultivation of Polygonatum odoratum has not been paid attention to by everyone, so what do we need to pay attention to? Next, let's take a look at it with the pro-farm network.

1. Soil

The soil for planting Polygonatum odoratum should first of all be selected in the land where crop rotation is frequent, because it cannot be cropped continuously, the yield of continuous cropping is not high, and it is easy to get sick. Secondly, the soil of the planting land should be relatively loose, the drainage system should be more perfect, and the land with sufficient light and nutrients should be more adequate, preferably acidic sand. Finally, it is necessary to pay attention to the leveling of the ground when preparing the land so as to facilitate the later management of the ditch.

2. Time

There are two planting times for Polygonatum odoratum, which are divided into spring and autumn, usually in April and October of each year, when the weather temperature is about 15 to 20 degrees. During this time, the survival rate of seeds will be higher. At the same time, it is best to choose sunny days when sowing, so that the seeds will sprout faster.

3. Density

The planting density is also a point to pay attention to, because if the planting is too dense, then the permeability of the field will become worse, then Polygonatum odoratum is easy to get sick, and in this way, if exposed to the sun after heavy rain, it is very difficult to drain water, so it is easy to cause root rot. So the best planting density is 30 to 40 centimeters between rows and 15 to 20 centimeters between plants, which can not only avoid some diseases, but also reduce a lot of labor, and achieve the effect of high yield at the same time.

4. Fertilizer and water

Generally speaking, as long as the planting of Polygonatum odoratum is sufficient when applying base fertilizer, then basically there is no need for topdressing in the first year, but we do not rule out the shortage of base fertilizer. therefore, we need to carry out reasonable topdressing according to the growth of Polygonatum odoratum seedlings and various conditions. if the plant grows very slowly and the leaves are yellow, it means malnutrition and topdressing is needed. Topdressing we can use potash and phosphate fertilizer, we can also use farm manure and organic fertilizer. If the base fertilizer is fully applied in the first year, it will not be fertilized until the next spring. Polygonatum odoratum likes to be wet, so we should water it irregularly, especially in case of drought, and then pay attention to drainage during the rainy season.

5. Pest control

The common diseases of Polygonatum odoratum are root rot, leaf spot and gray spot. The main prospect of these three diseases is improper water management, excessive humidity in the field, and then high temperature, so there are a large number of bacteria, leading to the occurrence of the disease. So we can use chlorothalonil or carbendazim and Bordeaux solution for control. The main pest is grub, which is an underground pest, similar to the ground tiger, so it mainly damages the tubers of Polygonatum odoratum and has a great impact on the yield and quality of Polygonatum odoratum. The general control method is to use trichlorfon to irrigate roots.
