What should be paid attention to in the latest planting of Polygonatum odoratum

Polygonatum odoratum is a kind of lily family, mainly because its branches and leaves and lily are very similar, but underground tubers are completely different, although they all have nourishing effect, but polygonatum odoratum is not as well known as lily, but we can not deny its value, it is also a large proportion of traditional Chinese medicine, the scope of use is also relatively broad, and in recent years the planting of polygonatum odoratum is not beginning to be valued by everyone, so what do you need to pay attention to when planting polygonatum odoratum? Let's take a look at it together with the pro-agricultural network.

1. Soil

The soil for planting Polygonatum odoratum should first be selected in the land with frequent rotation, because it cannot be continuously cropped, the yield of continuous cropping is not high, and it is easy to develop diseases. Secondly, the soil of the planting land should be loose, the drainage system should be perfect, the light and nutrients should be sufficient, and the best is acidic sand. Finally, there is also a need to pay attention to the preparation of the ground when leveling, from a good ditch to facilitate the later management.

2. Time

There were two planting times for Polygonatum odoratum, spring and autumn. Generally, it was planted in April and October every year. At this time, the weather temperature was basically around 15 to 20 degrees Celsius. The survival rate of seeds would be higher during this period of time. At the same time, it was best to choose sunny days when sowing, so that the germination speed of seeds would be 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 very easy to develop, and if it encounters the exposure after heavy rain, the water is difficult to drain out, so it is easy to cause root rot. Therefore, the best planting density is 30 to 40 centimeters between rows and 15 to 20 centimeters between plants, which not only avoids the occurrence of some diseases, but also reduces a lot of labor, and at the same time can achieve high yield.

4, fertilizer water

Polygonatum odoratum planting generally as long as the base fertilizer is sufficient, then basically in the first year there is no need to carry out topdressing, but do not rule out the lack of base fertilizer, so we need to according to the growth of polygonatum odoratum seedlings and various aspects of the situation to carry out reasonable topdressing, if the plant grows very slowly, and the leaves are yellow, that is, malnutrition, then need to carry out topdressing, topdressing we can use potassium fertilizer and phosphorus fertilizer, You can also use farm manure and organic manure. If the base fertilizer is sufficient in the first year, it will have to wait until the spring of the second year to fertilize. Polygonatum it likes wet, so we have to water Polygonatum from time to time, especially when it is dry, followed by the rainy season when we should pay attention to drainage.

5, pest control

The common diseases of Polygonatum odoratum are root rot, leaf spot and gray spot. The main prospects of these three diseases are improper water management, excessive humidity in the field, and then high temperature, so a large number of bacteria are bred, resulting in the occurrence of diseases. Therefore, we can use chlorothalonil or carbendazim and bordeaux mixture to control them. The main pest is white grubs, it is an underground pest, similar to the ground tiger and the like, so the main damage to the tubers of Polygonatum odoratum, the yield and quality of Polygonatum odoratum have a great impact, the general control method is to use trichlorfon for root irrigation.
