The invention discloses a method for producing high-quality high-yield peel type traditional Chinese medicinal material eucommia bark. Nutrient is applied to the growing process of the eucommia bark, and the nutrient comprises the following components in percentage by weight: 10 to 30 percent of nucleotide salts, 20 to 70 percent of glucose, 10 to 20 percent of amino acid and 10 to 30 percent of medium trace elements, wherein the nucleotide salts are four sodium salts or potassium salts of 5'-mixed nucleotide, generated after ribonucleic acid alkali is hydrolyzed; and the medium trace elements are Zn, Mn, Mg, Fe and B, in particular zinc sulfate, manganese sulfate, magnesium sulfate, ferrous sulfate and borax. In term of the application method, the nutrient is dissolve in water and applied in a spray manner. The method is low in production cost, is convenient, is easy to produce and popularize in large scale, is strong in pertinence, is non-toxic and harmless, does not have residues or side effects, and has the functions of increasing yield, income and efficiency, increasing resistance and improving quality of bark type traditional Chinese medicinal materials.
