Planting method of Platycodon grandiflorum

Platycodon grandiflorum is a perennial herb, its value is relatively high, not only has a very high ornamental value, its root is also a kind of traditional Chinese medicine. And it is also used to pickle into pickles in the north of our country, which is a kind of plant with a wide range of uses. Now there are not a few people growing Platycodon grandiflorum, so how to grow Platycodon grandiflorum? What are the specific planting techniques? Today, the editor brings you the planting method of Platycodon grandiflorum. Let's have a look!

1. Land selection and preparation

The root capacity of Platycodon grandiflorum is not strong, so it needs to be planted on the soil with strong permeability and loose soil. Clean water is needed around the planting site, and the drainage and irrigation system is good, preferably on a half-shaded and half-sunny hillside. Prepare the soil in time after selecting the land, because the root of Platycodon grandiflorum is longer and thicker, so you need to make ridges, turn the ground deeply into ploughing, and then open ditches to pile up the soil on both sides. Field ridges with a width of 2 meters are made to provide a good growth environment for Platycodon grandiflorum.

2. Sowing seeds at the right time

Platycodon grandiflorum can be sown in the other three seasons except that it is not suitable for germination and emergence in the high temperature environment in summer. However, the best time is around mid-September and the Beginning of Spring every year, when sowing helps to promote the seed to take root and germinate. Enhance the growth ability of seedlings and improve the yield and quality. It is best to use strip sowing when sowing. After sowing, it is necessary to cover fine soil and plastic film in time to improve the water and fertilizer conservation of soil, prevent the loss of water and fertilizer, and affect the germination rate of seeds. After emergence, the plastic film should be opened in time to ensure that the seedlings can grow normally.

3. Field management

When the seedlings break the soil and grow to about 2 cm, it is necessary to observe the growth and density of the seedlings and do a good job of thinning seedlings in time. Then wait until the seedlings elongate again, you can start to fix the seedlings, when fixing the seedlings to control the distance between the seedlings to prevent the growth of too dense. And in the middle of the seedlings, it is necessary to pull out the dead and weak seedlings, and then replenish the seedlings to ensure the yield. Weeding should be done regularly in the seedling stage of Platycodon grandiflorum to prevent excessive weeds from leading to malnutrition. After weeding, topdressing in time, you can use mature farm manure, and then in the later stage according to the growth of Platycodon grandiflorum.

4. Disease control

Platycodon grandiflorum is most afraid of all kinds of diseases and insect pests, which can lead to no harvest of Platycodon granules when the diseases and insect pests are serious. For example, common diseases include spot blight, insect pests, aphids and so on. No matter what the diseases and insect pests are, the harm to Platycodon grandiflorum is very serious, so we must strengthen field management and disinfect them regularly. Control the nutrition in fertilizer, enhance the disease resistance of Platycodon grandiflorum, improve the immune ability and reduce the incidence. After the disease, the diseased plants should be removed in time, the specific diseases and insect pests should be examined, and then the corresponding treatment methods should be used to control the disease so as to reduce the loss to the minimum.

The above is a brief introduction of Platycodon grandiflorum planting technology, it should be noted that when harvesting, we must pay attention not to hurt the root of Platycodon grandiflorum, to prevent the occurrence of wounds, leading to wound infection and decay. Because the highest value of Platycodon grandiflorum is the root, the root disease basically lost the commodity value.
