As a vital medicinal herb and health ingredient, the quality and active components of *Eucommia ulmoides* (duzhong) are directly influenced by its growth environment. Among these factors, soil pH value and mineral composition play pivotal roles in determining plant health, growth rate, and the accumulation of bioactive compounds. Through scientific research and optimized agricultural practices, we can enhance duzhong's quality by fine-tuning soil conditions.
Soil pH dictates the solubility and availability of nutrients to plants. Studies show that duzhong thrives best in slightly acidic to neutral soils with a pH range of 6.0–7.0. Within this range, essential minerals such as calcium (Ca), magnesium (Mg), iron (Fe), and manganese (Mn) are more readily absorbed by roots, supporting optimal growth and active compound synthesis. Additionally, a suitable pH fosters the proliferation of beneficial microorganisms—including nitrogen-fixing bacteria and organic matter decomposing microbial communities—which improve soil structure and nutrient cycling efficiency.
If the soil becomes too acidic (pH < 6.0), aluminum (Al) and manganese (Mn) become overly soluble, disrupting Ca/Mg absorption and inhibiting root development. Conversely, excessively alkaline soils (pH > 7.0) reduce the availability of Fe and Mn, leading to slow growth, chlorosis (yellowing of leaves), and compromised metabolic functions. To maintain optimal pH levels, regular soil testing is conducted, followed by adjustments using agricultural lime, gypsum, or organic matter applications.
High-quality duzhong soil requires a balanced supply of macronutrients and micronutrients. Research indicates that an ideal N:P:K ratio of 3:1:2 promotes robust root development, enhances plant stress resistance, thickens leaves, and maximizes active ingredient accumulation.
Calcium (Ca) and Magnesium (Mg): Essential for cell wall formation and photosynthesis.
Iron (Fe) and Manganese (Mn): Involved in respiratory metabolism and enzymatic regulation.
Boron (B) and Zinc (Zn): Boost disease resistance and further activate bioactive compound synthesis.
By implementing precision fertilization and soil amendment techniques, growers achieve a scientifically optimized "golden ratio" of nutrients, significantly enhancing duzhong's growth quality and economic value.
