Abstract
The invention discloses a compound for preventing the ligusticum wallichii root rot. The problem of pesticide remaining in the ligusticum wallichii root rot preventing in the prior art is solved. The compound is prepared through following raw materials including, by weight, 10-18 parts of fructus cnidii, 4-9 parts of large-leaved gentian and 6-12 parts of cortex dictamni. The method for the compound comprises the following steps of raw material weighing, ethyl alcohol adding, heating and backflow, filtering, ethyl alcohol recycling, concentrating, concentrated liquid obtaining, adding of a suspending agent and a dispersing agent into the concentrated liquid and compound obtaining. The invention further discloses application of the compound to preparing of pesticide for preventing the ligusticum wallichii root rot. According to the compound and the preparing method and application thereof, ligusticum wallichii root rot prevention is definite and effective, degrading is easy, pesticide remaining is avoided, and the quality of ligusticum wallichii cannot be influenced. The method is simple in technology, operation is simple and convenient, and the method is suitable for usage and popularization.
Description
technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a composition for preventing and treating Rhizoma Chuanxiong root rot, its preparation method and application. Background technique [0002] Chuanxiong is a commonly used traditional Chinese medicine, traditionally used as the dried rhizome of Ligusticum chuanxiongHort. In summer, when the node disk on the stem is obviously protruding and slightly purple, it is excavated, the sediment is removed, dried in the sun, and then the fibrous roots are removed. [0003] Rhizoma Chuanxiong is pungent and warm in nature; it returns to the Liver, Gallbladder, and Pericardium Meridians. It has the functions of promoting blood circulation and promoting qi, expelling wind and relieving pain, and is used for chest obstruction and heartache, tingling pain in the chest and hypochondrium, swelling pain in tumbling, irregular menstruation, amenorrhea dysmenorrhea, abdominal pain ...
