Embodiment 1

[0042] Embodiment 1, the preparation of special-purpose growth regulator of Stevia rebaudiana

[0043] method one:

[0044] 1. Preparation of fermentation products

[0045] 1) Cultivate

[0046] Bacillus sp. Y-25CGMCC 4092 was inoculated into seed tanks and cultured for 12 hours according to the conventional method, and then inoculated into fermentors for 37°C culture (the medium was LB medium, the formula was peptone 10g / L, yeast powder 5g / L, sodium chloride 10g / L.) After 24 hours, the culture solution obtained had a bacterial concentration of 2×10 8 cfu / mL, spare;

[0047] 2) fermentation

[0048] Add lignite (the organic matter content of lignite is 78% (mass percentage), humic acid content is 67% (mass percentage), originating from the Huolinhe area of ​​Inner Mongolia Autonomous Region), wheat bran, straw, and water in proportion to fermentation In the tank, at the same time, the bacillus culture solution prepared above was inserted and fully mixed, and aerobically ...

Embodiment 2

[0069] Embodiment 2, the application of special-purpose growth regulator of Stevia rebaudiana

[0070] 1. Application of growth regulator 1

[0071] Take by weighing 1kg the special-purpose growth regulator 1 of stevia rebaudiana that obtains by embodiment 1, be dissolved in 1000L clear water, fully stir and mix, obtain foliage fertilizer dilution, the average per mu of stevia special-purpose biological growth regulator dilution is 30L .

[0072] When stevia rebaudiana (Stevia rebaudiana Bertoni, from Shenyang Yihua Ecological Park Development Co., Ltd.) was transplanted to the field for about one month, it was sprayed once every 7 days and sprayed twice continuously; During two months, spray 1 time every 7 days and spray 2 times in a row; when about 15 days before stevia flowering, spray 1 time every 7 days and spray 2 times in a row; For the middle and upper leaves of Chrysanthemum chrysanthemum, the main method is to spray on the back of the leaves;

Abstract

The invention discloses a composition for promoting growth of stevia rebaudiana, and a preparation method for the composition. The composition consists of a fermentation product, monopotassium phosphate, diammonium phosphate, and a trace element complexing agent; and the fermentation product is prepared by the following steps of: uniformly mixing bacillus sp. and lignite, fermenting, and collecting a product to obtain the fermentation product. Through experiment, organism growth regulator special for the stevia rebaudiana is prepared, and the method has the advantages that by applying the growth regulator special for the stevia rebaudiana appropriately, micro-ecological environment of the stevia rebaudiana is effectively improved, micro-ecological balance is adjusted, and nutrient supply conditions are improved.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a composition for promoting the growth of Stevia rebaudiana and a preparation method thereof. Background technique [0002] Stevia (Stevia rebaudianum Bertoni) is a perennial herb of Asteraceae native to Paraguay. The stevioside extracted from its leaves is a natural strong sweetener, and its sweetness is 150-300 times that of sucrose. After a large number of long-term toxicological and pharmacological studies, it has been proved that stevioside has no potential or genetic hazards in the body, and its safety has been recognized by international organizations such as FAO and WHO. In 2004, the World Health Organization officially passed The decision to allow stevioside to be used worldwide, along with its safety being recognized by the world, has further increased its economic benefits. In recent years, people have paid more and more attention to healthy diet. As a sweetener, steviosi...
