Special fertilizer for red sage root and fertilization method of red sage root

Abstract

The invention discloses a special fertilizer for red sage root and a fertilization method of red sage root. The total amount of the applied fertilizer is as follows: 204.55-218.07 kg / hm<2> for N, 248.26-263.09 kg / hm<2> for P2O5, 127.84-135.74 kg / hm<2> for K2O, 3.06-3.28 kg / hm<2> for MnSO4 and 3.06-3.27 kg / hm<2> for ZnSO4; the fertilizer is applied twice to be respectively used as the basal fertilizer and the additional fertilizer; the amount of the applied basal fertilizer is as follows: 30% of the total amount of N, 100% of the total amount of P2O5, 70% of the total amount of K2O and 50% of the total amount of MnSO4 and ZnSO4; and the amount of the applied additional fertilizer is as follows: 70% of the total amount of N, 30% of the total amount of K2O and 50% of the total amount of MnSO4 and ZnSO4. By the optimal combination of major elements and trace elements, the yield of the red sage root is increased by 20.5-25.6%, the output value is increased by 31.5-40.5%, and the first-grade product rate of the red sage root is increased by 17.1-19.3%.

Description

technical field [0001] The invention relates to the field of salvia plantation, in particular to a special fertilizer for salvia miltiorrhiza and a fertilization method for salvia miltiorrhiza. Background technique [0002] Salvia miltiorrhiza Bunge is a perennial herb of Lamiaceae. Its dried root is used as medicine. It is clinically used for the treatment of coronary heart disease, cerebral embolism, heart disease, angina pectoris and other diseases. Salvia miltiorrhiza is mainly distributed in Northeast China, North China, Northwest China and other places in my country. [0003] With the increasingly in-depth chemical and pharmacological research of Salvia miltiorrhiza and the requirements of pharmaceutical companies to produce traditional Chinese medicine raw materials, the demand for Danshen at home and abroad is increasing. Only relying on traditional limited wild Salvia miltiorrhiza can no longer meet the needs of modern pharmaceuticals. In recent years, the market ...

AI Technical Summary

Problems solved by technology

If the amount of fertilizer is insufficient, it will affect the yield and appearance quality; if the amount of fertilizer is too large, it will exceed the nutrient requirements of Danshen, and the pesticide residues will exceed the standard, which will reduce the medicinal quality of Danshen

At present, the research on the key technology and theory of formula fertilization in the cultivation of Salvia miltiorrhiza is still very weak. According to the data, there is still a lack of systematic research at home and abroad. The research on the fertilization formula technology of Danshen local artificial cultivation is an important basis for realizing the standardization of Salvia miltiorrhiza. The purpose of this study It is to formulate the standardization index of salvia miltiorrhiza, provide optimized fertilization technology formula, form the fertilization formula technology of artificial cultivation of salvia miltiorrhiza in the original place, and ensure the output and quality of artificial cultivation of red sage root in the authentic place of origin
