Suitable for early sowing of Chinese herbal medicines
Chinese herbal medicines come in a wide variety, each with its own growth habits and cultivation requirements. Over the years, many farmers have developed long-term experience in cultivating these plants, and they believe that certain herbs can be planted earlier in the season. These early-planted herbs often exhibit faster germination, stronger growth, better resistance to diseases, and higher yields.
One commonly used herb is Platycodon grandiflorum, also known as Balloon Flower, which is widely used both medicinally and as a food ingredient. It grows naturally in mountainous areas, hills, and plains across China. Currently, there are four main production regions and several secondary ones. Traditionally, it has been sown in spring or summer using about 2 kg of seeds per acre. The seeds are evenly distributed on the soil surface, and the field is often soaked and broken up. However, this method has some drawbacks: it's difficult for the seeds to emerge during dry periods, and weeds can interfere with seedling growth.
In contrast, winter planting offers significant advantages. Seeds are mixed with soil in a specific ratio and then sown without covering. Through the snow and rain of winter, the seeds make full contact with the surface and begin to expand. By early spring, the seedlings emerge quickly. This method results in more uniform sprouting, earlier emergence, and healthier plants.
Another important herb is Bupleurum chinense, commonly known as Chaihu. Historically, it was mainly found in the wild, leading to a supply-demand imbalance. In the 1980s, efforts were made to cultivate it more extensively, primarily in spring. However, Bupleurum seeds have a tough outer layer, and germination usually takes 18–25 days at temperatures above 20°C. Over time, low germination rates have become a major challenge for its large-scale cultivation.
Farmers have found that planting Bupleurum in winter helps improve germination. During winter, the cold climate gradually weakens the hard seed coat, making it easier for the seeds to germinate when spring arrives. Another effective practice is to broadcast Bupleurum seeds in wheat fields. After the wheat harvest, the Bupleurum begins to grow rapidly. This natural method not only improves germination but also enhances the quality of the final product. Winter planting has proven to be an effective and reliable approach.
Atractylodes macrocephala, commonly known as Baizhu, is another widely used medicinal herb. Its growth cycle typically lasts two years: one year for seedling development and another for mature cultivation. Traditionally, seedlings are started around the Qingming Festival, when the weather is mild. Seedlings usually appear 7–10 days after sowing. However, this method has several issues: the seedlings are short due to shallow sowing, they are weak and prone to disease, and yield tends to be low.
By advancing the sowing time to colder periods, these problems can be addressed. Cold-seeded Atractylodes seeds are generally planted deeper to avoid freezing. The resulting seedlings grow more vigorously, emerge faster, and produce higher yields. Early emergence also leads to stronger, more resilient plants. Experienced farmers often use this technique to ensure better growth and higher productivity.
