Stevia rebaudiana seedling nutrient solution and preparation method thereof

Abstract

The invention provides a stevia rebaudiana seedling nutrient solution and a preparation method thereof. The stevia rebaudiana young seedling nutrient solution is prepared from the following ingredients in parts by weight: 0.4 to 0.6 part of urea, 2 to 4 parts of calcium superphosphate, 0.3 to 0.5 part of potassium chloride, 0.008 to 0.012 part of brassinolide, 0.03 to 0.05 part of sodium borate, 0.02 to 0.04 part of zinc sulfate, 0.02 to 0.04 part of ferrous sulfate, 1 to 2 parts of edetate disodium, 4 to 5 parts of fulvic acid, 0.009 to 0.012 part of isoflavone, 2 to 4 parts of amino acid, 12 to 15 parts of polyglutamic acid, 0.1 to 0.3 part of matrine, 10 to 12 parts of ethyl alcohol and 1000 parts of water. The brassinolide, the isoflavone and the matrine are dissolved into the ethyl alcohol; the other ingredients are dissolved into the water; mixing is performed, and the stevia rebaudiana seedling nutrient solution is obtained. The stevia rebaudiana seedling nutrient solution is composite nutrition liquid; all the ingredients are mutually matched; the growth and the health of stevia rebaudiana seedlings are promoted; the transplanting survival rate of the stevia rebaudiana seedlings is improved.

Description

technical field [0001] The invention relates to the technical field of stevia planting, in particular to a stevia seedling nutrient solution and a preparation method thereof. Background technique [0002] Stevia is a perennial herb of the genus Stevia in the Asteraceae family. The whole Stevia plant contains sugar, and the sweetness of the leaves is the highest, containing about 14% glycosides. The glycosides of the branches are equivalent to half of the leaves. Stevia leaves can be used as sugar after drying and crushing, or through ethanol precipitation Obtain stevioside, the sweetness is equivalent to 250-300 times that of white sugar, and the calories are only 1 / 300 of white sugar. Not only that, stevioside has no toxic side effects, no carcinogens, safe to eat, regular consumption can prevent high blood pressure , diabetes, obesity, heart disease, dental caries and other diseases, it is an ideal sweetener to replace sucrose. At present, it has been widely used in food...

AI Technical Summary

Problems solved by technology

[0003] Stevia mostly uses asexual cutting seedlings to propagate seedlings. Stevia cutting seedlings are an effective way to maintain the purity of stevia varieties, prevent degradation and expand seedling breeding. At this time, the stevia seedlings are relatively fragile, which will reduce the survival rate of stevia transplanting.
