How to formulate Chinese medicine for fertilization

In recent years, the prices of various fertilizers have increased year by year. In the production of medicinal materials, how to obtain greater economic benefits through small fertilization through rational fertilization, and to achieve the purpose of increasing production and income, fertilizing soil, and saving costs, is an important problem that needs to be solved urgently. Formulated fertilization is a comprehensive application of modern agricultural science and technology achievements. According to the fertilizer requirements of medicinal plants, soil fertility status and fertilizer effect, under the conditions of organic fertilizer, nitrogen, phosphorus, potassium and trace element fertilizers are proposed beforehand. Appropriate amount and ratio and corresponding fertilization techniques. The specific practices are as follows:
Soil testing The effective nutrient content of cultivated land is tested to see which nutrients are necessary and which are less.
Formula After analyzing the soil test results, according to the medicinal plants required for fertilizer rules, the amount of fertilizer required to make up what to make up. (The above two steps are generally completed by professional units.)
Fertilization is mainly based on reasonable fertilization methods (such as point application, ridge application, spreading, pouring, etc.) and the best fertilization period (one step by the professional unit in the topdressing period, the implementation of the drug farmers).
In production, if the soil is tested one by one, that is, soil testing first, and then formulating fertilization is the most ideal, but it is difficult to achieve one household. Therefore, fertilizers should contain fertilizers containing nitrogen, phosphorus and potassium in the fertilizer selection, and the application ratio is preferably 1:0.29 to 0.40: 0.29 to 0.40. If the proportion of chemical fertilizers that have been purchased is not suitable, the method of adding nitrogen fertilizer and potassium fertilizer can be adjusted.
Precautions Formula fertilization must be carried out under the premise of fully understanding the nutritional characteristics of the medicinal plants, soil fertility status and supply performance, climatic conditions and cultivation techniques, and rationally managing the amount and method of base fertilizer, seed fertilizer and top dressing, and gradually forming suitable local production conditions. Rational fertilization system. In addition, attention should be paid to formulating fertilization according to the effects of synthesis and accumulation of active ingredients: the synthesis and accumulation of different active ingredients in different medicinal plants have different laws, and different fertilizers have different effects on them. While fertilizing to increase the yield of the medicinal materials, it is necessary to ensure a high content of the active ingredients of the medicinal materials. For example, nitrogen fertilizer has a certain promoting effect on the synthesis and accumulation of alkaloids, but inhibits other components such as green pump acid and flavonoids. In this way, when formulating fertilization, it is necessary to consider the law of synthesis and accumulation of different active ingredients, the type, quantity and application period of the applied fertilizer, and should be based on the principle of increasing or guaranteeing a certain content of the active ingredient.
According to different medicinal plants and different active ingredients, the production and application of special fertilizers for medicinal plants is the direction that requires arduous efforts in the production of medicinal materials.
