Cultivation Techniques of High-yielding Japanese Red Ginseng
Hao Lishen is a revolutionary, high-yield carrot variety developed by Japanese scientists using advanced gene-enhancement technology. This special type of carrot not only offers excellent cancer-fighting properties but also delivers impressive agricultural returns. It can produce up to 10,000 kilograms per mu (approximately 667 square meters), and it's suitable for planting throughout the year. Especially during the summer season, it performs exceptionally well, with a profit of about 4,000 yuan per growing cycle. When processed through quick-freezing preservation, the economic benefits can even double.
The growth cycle of Hao Lishen is relatively short, lasting between 90 to 100 days, making it ideal for various regions and farming conditions. Its adaptability and resilience make it a great choice for both small-scale and large-scale cultivation.
To grow Hao Lishen successfully, certain key practices should be followed:
1. **Soil Selection**: The best plots are those with sandy soil or double-crop land, which provide good drainage and nutrient retention.
2. **Fertilization**: Apply a generous amount of farmyard manure—more than 6,000 kilograms per acre. Additionally, use 15 kilograms of potassium sulfate and add appropriate amounts of micronutrients such as molybdenum and selenium to enhance plant health and yield.
3. **Land Preparation**: Plow the soil to a depth of over 20 centimeters, then break up clods and ensure the soil is fine and smooth to create an ideal seedbed.
4. **Sowing Techniques**: Plant seeds in rows spaced 20 centimeters apart, with each seed placed 2 centimeters deep. Cover the seeds with a thin layer of soil (about 1 cm). Water gently if there's a drought, but avoid flooding, as this can damage the young plants. Avoid overcrowding to save on labor and improve efficiency.
5. **Weed Control**: Use specialized herbicides designed for carrots, such as Dimethylamine Phosphorus, to effectively manage weeds. Manual weeding is time-consuming and less efficient, so chemical control is recommended. Do not use conventional herbicides, as they may harm the crop.
6. **Thinning Seedlings**: Once the seedlings reach a height of 3–5 cm, thin them out to maintain a spacing of 5–10 cm between plants. This helps prevent competition for light and water, ensuring better growth and higher yields.
7. **Water Management**: Excessive water can lead to root rot and reduce the quality of the harvest, making the carrots difficult to sell. After heavy rains, promptly drain excess water and loosen the soil to maintain optimal growing conditions and ensure a high yield and profitability.
By following these detailed steps, farmers can maximize the potential of Hao Lishen, achieving both high productivity and superior quality in their carrot crops.
