There are numerous types of herbal medicines, most of which come from perennial herbaceous plants. These plants have traditionally grown in the wild, relying mainly on natural weather conditions for their development. However, due to the unique nutritional requirements and characteristics of Chinese herbal medicines, there is limited research into their fertilization techniques. As a result, current practices in the application of fertilizers for medicinal herbs are often imbalanced.
One common approach is to avoid fertilization altogether for wild-type herbs, with only organic fertilizers being used if necessary. The other approach involves applying large amounts of water and chemical fertilizers, similar to conventional crop farming, without considering the specific needs of the medicinal plants. Both methods are not ideal for ensuring high-quality herb production or maximizing medicinal efficacy.
Studies conducted in parts of Hebei and Henan show that local farmers primarily rely on organic manure and traditional experience for fertilization. Advanced techniques such as soil testing and nutrient diagnosis are rarely used. In most cases, top-dressing is not properly applied, and base fertilizers are typically applied in the fall, with some used in the spring. These base fertilizers are usually organic, and top-dressing often consists of composted materials like cake fertilizer or human waste.
Experts emphasize that the goal of fertilizing Chinese herbal medicine should not only focus on increasing yield but also on enhancing the medicinal properties of the plants. To achieve both higher quantity and quality, it is essential to tailor fertilization strategies based on the specific characteristics of the medicinal parts—such as roots, leaves, flowers, or fruits.
It is recommended to combine organic and chemical fertilizers in appropriate amounts. This combination can improve both the yield and the potency of the herbs. Recent studies have shown that using only organic fertilizers may not be suitable for all medicinal plants. For example, human urine can inhibit root development in ginseng, while specialized compound fertilizers produce better results for certain species like safflower.
The principle behind chemical fertilizer use is to apply them cautiously alongside organic materials. Nitrogen should be used sparingly, while phosphorus and potassium should be emphasized. Trace elements also play a key role, especially when targeting secondary metabolites, which are often responsible for the medicinal effects. When applying trace element fertilizers, they must be mixed well with organic material to ensure even distribution. If sprayed directly, the concentration and frequency must be carefully controlled to avoid over-application or damage to the plants.
By adopting a more scientific and tailored approach to fertilization, farmers can enhance both the productivity and therapeutic value of Chinese herbal medicines.
