Detailed Guide to Platycodon grandiflorus Cultivation: Per-Mu Returns Generally Around 20,000 to 30,000 Yuan
SummarySowing: Can be sown in spring, autumn and winter; remove the film promptly after seedlings emerge. Planting: Thin and space the seedlings in time. Weeding: Weed regularly to prevent weeds from taking nutrients. Fertilizing: Apply timely topdressing, mainly with decomposed farmyard manure. Pest and disease control: Conduct regular inspections, and carry out timely prevention and treatment when pests or diseases are found. Per-mu returns: Under conventional cultivation methods, per-mu returns are about 20,000-30,000 yuan.
Per-Mu Yield and Returns of Platycodon grandiflorus
Platycodon grandiflorus is one of the 40 major bulk varieties of Chinese medicinal materials. It has extremely high ornamental value and is a plant with a very wide range of uses. With superior varieties, good management, and no pest or disease disasters, the per-mu yield is generally about 1,200 kg, with a maximum of no more than 1,500 kg. Its price fluctuates high and low according to market conditions, at roughly 18-24 yuan per jin, so the per-mu returns are about 20,000-30,000 yuan.
Planting Environment
The root capacity of Platycodon grandiflorus is relatively poor, so when planting, it is necessary to choose soil that is relatively loose and highly permeable. The planting site also needs a pollution-free water source and good drainage and irrigation conditions, with a semi-shaded, semi-sunny hillside area being best.
After the planting site is selected, prepare the land. The roots of Platycodon grandiflorus are relatively thick and long, so when preparing the land it is necessary to make ridges. First carry out medium-depth plowing and deep turning, then open furrows, placing the soil from the furrows on both sides to make field ridges 2 m wide, providing a high-quality growing environment for Platycodon grandiflorus.
Sowing
Platycodon grandiflorus has strong adaptability and can be sown in spring, autumn and winter, because the summer temperature is too high and unsuitable for germination and seedling emergence.
The best sowing time is September each year and around the Beginning of Spring. This period helps the seeds take root and germinate, improves their growth capacity, and thereby improves their quality and yield.
The best sowing method is drilling. After sowing, cover with soil and film in time, which can improve the soil's ability to retain fertilizer and water, preventing the loss of water and fertilizer and avoiding effects on the seed germination rate. After the seedlings emerge, remove the film promptly to ensure normal growth of the young seedlings.
Later-Stage Management
After the young seedlings grow to about 2 cm, carry out thinning and spacing in time according to their growth conditions and density.
Once the young seedlings grow a bit larger, they can be finalized. Be sure to control the spacing of the finalized seedlings well to prevent overly dense growth. When thinning, it is also necessary to pull out dead and weak seedlings, then replant to ensure yield.
In the later stage, regular weeding is also needed to prevent weeds from taking nutrients and affecting the growth of Platycodon grandiflorus. Apply timely topdressing, mainly with decomposed farmyard manure, which helps improve quality and yield.
Pest and Disease Control
If Platycodon grandiflorus suffers from pests or diseases, it will affect returns, and in severe cases it can lead to a total loss of the Platycodon grandiflorus harvest. For example, the most common pests and diseases include leaf spot and aphids.
Pests and diseases are extremely harmful to Platycodon grandiflorus, so field management must be strengthened and regular disinfection carried out. Reasonable topdressing helps improve the disease resistance of Platycodon grandiflorus, enhance immunity, and thereby reduce the incidence of disease.
Conduct regular inspections to promptly detect pests and diseases, and carry out timely prevention and treatment to avoid unnecessary losses.
