Because the nutritional rules and characteristics of Chinese herbal medicines are more prominent, people have little research on their fertilization techniques, which makes there are two kinds of biases in the application of Chinese herbal medicines. One thinks that wild-type Chinese herbal medicines do not need fertilization, especially fertilizers. Organic Fertilizer. The second is to apply fertilization methods for field crops, and to stimulate the production of large water and large fertilizers, but not for the characteristics of Chinese herbal medicine. These two conditions are unfavorable for the production of herbs and the improvement of efficacy of artificially cultivated Chinese herbal medicines. According to the surveys in some areas of Hebei and Henan, the local fertilization management of Chinese herbal medicines is mainly based on organic fertilizers. Based on experience and fertilization, advanced techniques such as soil testing and medicinal plant nutrition diagnosis cannot be applied in fertilization decision-making. Generally, in the fertilization method, the heavy fertilizer is not applied. Most of the base fertilizer is used in the autumn, and a small part is used in the spring. The base fertilizer is organic fertilizer, and the topdressing fertilizer uses decomposed organic fertilizer, such as cake fertilizer (bean cake, sesame cake) and human excrement.
Expert analysis: The fertilization goal of Chinese herbal medicine should not only consider how to increase the yield of medicinal materials, but also focus on improving the efficacy of Chinese herbal medicines. As for how to apply the principle of balanced fertilization to the fertilization of Chinese herbal medicines, we must first see that there are many kinds of Chinese herbal medicines. For Chinese herbal medicines with different medicinal organs, in order to obtain higher medicinal materials and sufficient efficacy, it is necessary to Organ characteristics differ in fertilization.
Chinese herbal medicine fertilization should apply an appropriate amount of chemical fertilizer on the basis of organic fertilizer, and the combined application of the two can contribute to the comprehensive improvement of output and efficacy. In recent years, some studies have shown that the use of organic fertilizer alone is not completely suitable for various medicinal plants. For example, human excrement is easy to inhibit the development of fibrous roots on ginseng and American ginseng; the effect of applying organic fertilizer on scutellaria is not as good as that of special fertilizer. The effect is good.
On the basis of the application of organic fertilizer, the application principle of chemical fertilizer is: careful application of chemical nitrogen fertilizer, emphasis on the application of chemical phosphorus and potassium fertilizer, and application of trace element fertilizer. For example, Chinese herbal medicine plants with flowers and fruits as medicinal organs should pay attention to the application of phosphorus and potassium fertilizers; Chinese herbal medicine plants with roots and bulbs as medicinal organs should pay special attention to the application of potassium fertilizer. For the fertilization of various Chinese herbal plants, the use of chemical nitrogen fertilizers must be particularly cautious, excessive nitrogen application will lead to reduced drug properties or long and bad roots. Because Chinese herbal medicines need to obtain the right amount of medicinal materials and have higher efficacy, according to the research of modern medicinal chemistry, most of the active ingredients of the drug action are some secondary metabolites in the body, for the output of these components. The effect of the application, not only to ensure a large number of elements but also the participation of trace elements in the fertilization supply. However, a small amount of trace element fertilizer (usually between 0.2 and 2 kg per mu, depending on the element) must be mixed with a large amount of organic fertilizer before it can be applied evenly. When the trace element fertilizer is directly sprayed, it is necessary to grasp the proper concentration and number of uses of the fertilizer. This will have the desired effect.
