Abstract

The invention relates to the technical field of agricultural seed breeding, and particularly discloses a seed soaking liquid for promoting seed germination of stevia rebaudiana and a preparation method. The preparation method comprises the following steps: respectively weighing folium artemisiae argyi, fructus cnidii, folium isatidis, gallnut, honeysuckle and liquorice, crushing, adding into a reactor, adding a solvent, namely, ethanol, performing heating reflux extraction for 1-2 hours under ultrasonic conditions, filtering, and washing filter residues; repeating the extraction operator twice, and combining filtrate and washing liquor so as to obtain a mixed extraction liquid; respectively weighing tender willow twigs and tender aspen leaves, smashing in a container, adding water to soak for 1-2 hours at the room temperature, and filtering so as to obtain a soaking liquid; extracting a mixed liquid and a soaking liquid, combining the liquids, concentrating, adding gibberellins into the mixed concentrated liquid, and dissolving sufficiently, so as to obtain the seed soaking liquid. By adopting the seed soaking liquid disclosed by the invention, seed germination can be effectively promoted, a relatively good sterilization and disinfection function can be achieved; the preparation method is simple, convenient to operate, applicable to popularization and application, and relatively good in application value.

Description

technical field [0001] The invention relates to the technical field of agricultural seed breeding, in particular to a seed soaking solution for promoting the germination of Stevia rebaudiana seeds and a preparation method thereof. Background technique [0002] Stevia is a perennial herbaceous plant of Compositae, native to subtropical South America. The roots, stems and leaves of Stevia rebaudiana contain steviol glycosides. Stevioside has the characteristics of high sweetness (200-300 times that of sucrose), low calorie (only 1 / 300 of sucrose), and can increase blood sugar, lower blood pressure, and promote metabolism. Heart disease, dental caries, etc. have a certain auxiliary effect, so it has increasingly attracted people's attention and attention, and has become the "third sugar source" after sucrose and synthetic sugar. [0003] In recent years, with the increase in demand for stevia, the planting area is also expanding. It is planted in Hainan in the south, Heilongj...
